Recalled: Mazda RX8 Sports Car

Mazda RX-8
If you own a Mazda RX8 sports car, then you better go ahead and read this. You see, your car might be one of those Mazda RX8 units that the Mazda Motor Corporation is recalling.

Plans of recalling the mentioned sports car from the company had already leaked out in the auto industry. And according to the company, all these moves are due to the fact that they have found out some defects with the vehicles’ rotary engines. And just in case you did not know, the Mazda RX8 is much known for its share of rotary engines. Add up the best kind of Mazda accessories, and you get an exemplary vehicle all in all. Except for the engine problems, of course.

Anyhow, this is the main reason why the company has decided on recalling the mentioned vehicle model. But if you do own Mazda RX8 vehicles that were made before the year 2003, then you need not worry for only those Mazda RX8 units that were produced in 2004 and in 2005 are included. There would also be some Mazda RX8 units that were created in 2006 that would be included in the recall.

According to the company, those vehicles that are part of the recall would be undergoing engine checks. And if the company finds that the vehicles’ engines would not pass a specific vacuum test, the engine units would be replaced. Owners would not have to shell out any finances for that. The company would be doing that free of charge.

The recall was brought about after the company had found out that some Mazda RX8 vehicles had engines that were leaking oil. And in the process, the oil that leaked out was damaging the vehicle’s catalytic converters. Furthermore, there were already reports of technical problems with the mentioned sports car.

The Mazda RX8 is a sports car that has first appeared back in the year 2001 when it debuted at the North American International Auto Show. It took the place of the Mazda RX 7 and is also powered by the Wankel rotary engine. But production of this sports car actually started only in the year 2003.

Mazda Hydrogen RE (Hybrid) - Commitment to a Greener Earth

Mazda RX-8 Hydrogen RE Dual-Fuel System
In order to contribute to a greener environment, Mazda Motor Corporation developed its well-known Hydrogen Rotary Engine (RE). The Hydrogen RE combines the company's trademark and original Zoom-Zoom performance, which Mazda calls the 'emotion of motion.' Since 2006, Mazda has already been leasing the RX-8 Hydrogen RE to various business corporations and government bodies. This is done in order to exhibit the efficiency of the engine in burning hydrogen as a means of generating motive power while at the same time, emitting zero carbon dioxide.

However, the hydrogen engine with its inherent 'emotion in motion' is more than just about clean performance. In fact, the overall dynamic and smooth driving experience is not compromised, because the RX-8 Hydrogen RE also offers an extremely powerful combustion engine that runs in gasoline. The model's dual-fuel system allows one to conveniently switch between gasoline and hydrogen fuel. The RX-8 Hydrogen RE still boasts of the remarkable features of the initial model RX-8, including a four-seater sports coupe and freestyle doors.

It was in the 2007 Tokyo Motor Show when Mazda first exhibited the new Mazda Hydrogen RE Hybrid. This year, Mazda has commenced its leasing of the hydrogen engine-powered car. It is through the utilization of the improved hybrid system and the refinements to the engine that excellent driving performance can be truly achieved. Some of the key concepts that were incorporated to the engine enhancements involve the following:

• powerful, high-speed, fun driving,

• larger trunk space and higher seating capacity (up to five full-sized adults),

• longer periods of in-between refueling.

Perhaps the main reason why RX-8 Hydrogen RE is one of the most outstanding creations of Mazda is because of the integration of their mission to keep their cars environment-friendly. The materials that were used to further reduce the emission of carbon dioxide were plant-derived. Thus, aside from providing optimum car performance, these materials also exhibit great resistance to shock, heat, and damages caused by fire and extreme weather conditions. RX Hydrogen RE also ensures versatility, as its interior and exterior design (seat covers, audio system) and other various features offer high-quality dynamism for all car enthusiasts.

Up to now, Mazda Motor Corporation is active in developing different technologies that serve as the company's contribution in achieving a sustainable energy and power plant. Mazda takes part in providing clean performing vehicles that run in alternative fuels like hydrogen, diesel, and gasoline.

For increased acceleration performance, the initial RX-8 Hydrogen RE was further enhanced. A total 40 percent increase in energy generation resulted from the enchanced power unit. This is done by changing the core unit (the main hydrogen RE) to a transverse-style layout. Consequently, the resistance to intake and exhaust, as well as the efficiency of combustion significantly increased, and thus, providing better output for a wide range of engine velocity.

In order to complement the brand new hydrogen RE, a unique hybrid system concept was also developed. This is because the traditional hydrogen RE has poor efficiency of combustion, decreased torque and revolution range, which are all resolved with the new hybrid system. In addition, the system combines higher capacity for hydrogen with a more extensive range for hydrogen fueling-twice more efficient than that of the initial RX-8 Hydrogen RE. Despite these key changes, the vehicle still uses a dual-fuel system; thereby living up to the car's practicality of use.
Instead of using the conventional combustion power-pump, the engine makes use of an electric motor rack. This is powered by the energy that comes from the combustion of hydrogen into electricity. Through this electric-drive innovation, the hybrid system is able to integrate maximal and efficient energy, quick responsiveness, and reduced consumption of fuel. Indeed, the new hybrid system concept paves the way for a driving pleasure that's like no other.

Moreover, the most exceptional components of the hybrid system that includes the hydrogen RE, inverter, generator, battery, and electric motor, all works together in fully optimizing car performance. This is done by altering and controlling the way the system generates electricity and how the battery is discharged or recharged. This mechanism of hybrid system monitoring is largely dependent on the driving conditions to which the vehicle is subjected to. For instance, if the car is pulling away after a stop, the system runs on battery power. However, during steady running, the vehicle runs on hydrogen RE and on generator. When accelerating, the vehicle also runs on battery power, along with the hydrogen RE and the generator power. Alternatively, during deceleration, regeneration occurs through the motor when engine braking. The hydrogen RE then stops from being inactive, unless there is a need to recharge the battery.

Just like the initial Mazda RX-8 Hydrogen RE, the hybrid model also makes use of Mazda Biotechmaterial, which is a collective term for the plant-derived materials, such as biofabric and bioplastic, which the company develops. In order to showcase the best of Mazda technologies that cares for the environment, the company collaborates with various universities, corporations, and also the government bodies in the Hiroshima region. This is part of the company's participation in the projects launched by government departments concerning Trade, Industry and Economy.
Mazda is the pioneering company which introduced the use of plant-derived bioplastic that exhibits remarkable properties such as resistance to intense shock, wear and tear, heat, and other unfavorable weather conditions. Additionally, the hybrid model of the Mazda Hydrogen RE makes use of these plant-derived materials for its seat covers and interior trimmings.

What's so great about using such materials-bioplastic and biofabric-is their quality appearance that is not compromised even with their resistance properties. The most probable reason for this is the careful production of these materials and the in-depth research that was conducted prior to their manufacture. In particular, a "compatibilizer" was developed in order to melt flexible components that contribute to improved absorption of shock.

Lastly, Mazda introduced recycling of bumpers as a way to decrease waste on landfills. The company developed a system of collecting damaged bumpers and since March 2005 (when RX-8 made use of recycled bumpers), recycled bumpers has been continually applied on newer models. The hybrid model of the RX-8 Hydrogen RE is not an exception.

The Features and Options of the Mazda RX 8

Mazda RX 8
The North American International Auto Show back in the year 2001 served as the avenue and channel for the Mazda Motor Corporation to show off and introduce to the public one of the vehicles that showed much potential and delivered greatly. This vehicle is the Mazda RX 8. During its introduction that year, it held a 250 PS JIS RENESIS engine that could produce some 247 units of horsepower at 8500 rpm. This engine won the International Engine of the Year award and the Best New Engine award in 2003.

The Mazda RX 8 was made available in two variants. These variants are the 197-horsepower base model that held an automatic transmission system, and the 238-horsepower performance model with a six speed manual transmission system. Of course, there are differences between these two trim levels. The Mazda RX 8 with the automatic transmission system holds standard features like air conditioning, sixteen inch wheels, power windows, power locks, and power mirrors. As per the trim level with the manual transmission system, this vehicle has the same features as per the other one however, it has added features like a limited slip differential, a sport tuned suspension, and 18 inch wheels and tires.

Mazda has designed and manufactured the Mazda RX 8 to be a vehicle that could be upgraded. And the company has made sure that there are packages available for those interested in sprucing up their Mazda RX 8 vehicles. One package is the Sport package. This gives the vehicle additional xenon headlights, a stability and traction control system, fog lights, a limited slip differential, larger brakes, a retuned suspension, and eighteen inch wheels and tires. There also is the Touring package that has features like the Sport package but adds several more features like a sunroof, a Bose audio system, a HomeLink system, and auto dimming mirrors. The last package is the Grand Touring package that is considered to be a combination of the previously mentioned two packages. This package is considered to be top of the line and has additional equipment and features for the Mazda RX 8 like a six way power adjustable and heated driver’s seat, leather upholstery, heated side mirrors, a navigation system, and an in-dash six disc CD changer.

Mazda RX-8
Mazda is offering something big in its new lineup. It includes all-new RX-8 that is made more powerful and lightweight. The release of said models has introduced it to be a sports car like no other.

Tetsu Nakazawa, RX-8 vehicle line manager, “Since its creation, the RX-8 has continued to win rave reviews from the automotive press. The RX-8 is a sports car built for the real world, ideal for zooming around a track, but equally suitable for taking the kids to soccer practice. It is a true sports car that can pull double duty."

2007 Mazda RX-8 is available as a 232-horsepower model engineered with a six-speed manual transmission or a 212-horsepower model engineered with a six-speed automatic with steering- wheel-mounted paddle shifters for a drive feel that is similar to that of Formula 1-style. Both cars are equipped with power door locks, mirrors, cruise control and an AM/FM/CD audio system with 6 speakers. Basically, most of these power parts are based from 1981 Mazda RX-7 parts only that they were upgraded and modified to come up with something better.

Underneath Mazda RX-8 is a race car character wraps in a sleek sports car. Its groundbreaking Rotary Engine Genesis engine (RENESIS) also known as the rebirth rotary engine is a product of meticulous design, engineering and manufacturing processes. In fact, it is the only rotary-powered passenger car around the globe which is mass produced. The engine is capable of efficiently performing the four essential processes crucial to keep the car powerful and agile.

Mazda RX-8 has a muscular built and a unique 'freestyle' design. It aims to prove that true sports car does need not compromise the space, convenience and comfort. Mazda engineers have designed the latest addition to exude versatility, style, performance and safety. In fact, they have integrated in the car several active and passive safety elements.

Active safety elements include the use of big ABS-equipped disc brakes on all wheels, accurate steering, Dynamic Stability Control and suspension systems. On the other hand, passive safety elements consist of the front airbags, seat-mounted side-curtain airbags and side-impact airbags. Furthermore, the front end and engine bay have ample crumple zones and the front seats are designed to diminish whiplash injuries.

Mazda has long established and maintained the tradition of developing new and exciting concept cars. A company that pours most of its time and energy into excellent engineering and ingenious designs, efforts bore fruit and Mazda gained success unmatched by most. From a small, Japanese, machine-tools company called Toyo Cork Kogyo Co., Ltd founded by Jujiro Matsuda, the company soon ventured into automobile production. In 1931, it introduced the ever Mazda car: the three-wheeled Mazda-Go.

Progressing onwards since that day, Mazda has become pioneer to a lot of innovations previously unknown to the automotive industry. It has also spawned a lot of impressive models since its launch as a car manufacturer – models which continue to gain admiration from all parts of the world. An example of these magnificent makes is the Mazda RX-8, which set the standards for genuine sports cars. Meanwhile, Mazda5’s communicative and dynamic concept was much praised and sold. Other top class Mazda vehicles that are popular today include the Mazda3, Mazda6, and the Mazda Miata. But despite the raves for these newer models, the Mazda classics remain to be much used and continue to traverse the roads of US and all parts of the world.

With the various Mazda vehicles being driven everywhere you go, more Mazda parts are being manufactured and supplied for consumers’ needs. More importantly, Mazda replacement parts abound, in case the urgent need to repair or replace comes, wherever you are. Crucial parts like filters, plugs, and fluids are always going to need replacement whatever auto brand and make you drive, and for Mazda cars, quality parts of these kinds are always available in the market. Maintenance and mechanical Mazda parts are made to OE specifications and are a perfect fit for perfect function anytime, anywhere. So whether you’re on your way to work, on a laborious off-road excursion or simply in a dangerous condition, you can trust on your Mazda parts to do its work and be available anywhere.

More than functionality, Mazda parts that accessorize are also widely accessible. When it comes to Mazda, style does not come after function – style is equal to function. Parts that offer both function and look enhancement are particularly important, and it is vital to always have Mazda parts like car covers and floor mats to protect your car against everyday hazards. For racing and speed enthusiasts, a wide line-up of street and race Mazda parts exist as well to make sure you zoom on that race track well-equipped and full of power.

Mazda Launches Revised Rx-8

Mazda RX-8

The Mazda Motor Corp. has launched its four-door, four-seater sports coupe RX-8 at this year’s North American International Auto Show with a serious bang. The new generation coupe boasts of a refreshed styling and an improved performance to wow more auto enthusiasts.

The Japanese automaker restyled the front and rear bumpers, wheels, headlights, and LED taillights while retaining the traditional rear-hinged rear doors. What is more, the automaker made the exhaust pipes and alloy wheels bigger than the previous model.

The RX-8 entertained a stiffened body by using a bar between the front suspension towers. Aside from enhancing stability of the car, it is also resorted to improve handling. The gearing was also modified to make the car even faster.

"Dating back to the Cosmo Sport released in 1967, every sports car ever developed by Mazda has had the same fundamental mission - to provide car lovers with a vehicle that's fun-to-drive, exciting to look at and easy to own," said Tetsu Nakazawa, Mazda North American Operations' RX-8 vehicle line manager. "The new RX-8 embodies that mission, conveying the unique and distinctive Mazda brand DNA to the fullest."

To make the revision catchier, Mazda’s pool of engineers zeroed in on innovation in three areas – styling, packaging and performance. "The enhancements made to RX-8's exterior, interior, packaging and performance takes it to a whole new level of visual and driving excitement," added Nakazawa.

Also, a flagship new sport package of the car will also be available. This will include a sport-tuned suspension, a body kit (with a new front bumper and side sills as well as fog lights and high-performance tyres) and Recaro front seats with leather side bolsters, reported Reuters.
Mazda RX-8
The revised models are expected to go on sale in the United Kingdom in the summer. According to the maker of Mazda spark plugs, prices and specifications will be announced nearer the time.

Separately, Mazda will be entertaining the use of new skins to lure more shoppers. Because it still takes four to five years to create a new car, there is a gap before the design themes reach production, said Franz von Holzhausen, the director of design for Mazda North American Operations.

"You will see this design philosophy in the future," von Holzhausen said last Wednesday at the AutoWeek Design Forum. “If Mazda doesn't evolve and reinvent its "skin," it runs the risk of becoming obsolete. Look at BMW. They recreated their skin. It was controversial but now they are selling more cars because of it.”

2008 Mazda Rx-8 Review - a Review of the 2008 Mazda Rx-8 Coupe

Mazda - Born to Be Wild

Zoom, zoom, zoom… Do you remember the old Mazda RX-7 or the ever popular autocross champion Mazda Miata? Mazda cars have always focused on exhilarating performance, as it is in fact the hallmark of their brand. Mazda was actually the first to put the performance benefits of Wankel's rotary engine to work in consumer production vehicles; now today the Renesis rotary engine which is found in the amazing new Mazda RX-8 has the title of International engine of the year.

With all of these choices, which is the best choice for you? Well to clearly identify that you need to take a trip down to your local Mazda shop and test drive a few, stop by Mazda parts and service to look over your choice of accessories, as once you have a Mazda you will have to make it your very own. There are so many ways to dress up and make your Mazda stand out in the crowd; it would truly be a shame not to take advantage of them.

Whether you are in Mazda USA, Mazda Canada, or Mazda Japan, you will find a high quality well performing vehicle for your needs. Unfortunately for you United States and Canada folks, you will have to take a backseat on the Mazda Bongo, which will be primarily sold in Japan. We're talking kitchen units, fold out beds, and elevated roof for heightened adult comfort. Great comfort, decent economy, and a look that will bring you back to the days of tie dye and flowers in your hair, that is what is know as the Mazda Bongo.

Mazda is not all performance cars and hippy vans of course; in fact there is quite a line of classy family coupes and sedans that would great in just about anyone's driveway. The Mazda Protege, also known as the Mazda 323 has been around since 1976 when it was first introduced as a rear wheel drive economy based compact. Built to last the Mazda Protege is not as of yet extinct, but has been promoted as the all new Mazda 3.

The all new Mazda 3 has a much roomier feel these days, and the engine choices will have you humming the entire way to work. They are all around great cars for everyone from your father to your teenager. The Mazda 3 is a definite winner. But if three is this good; you just have to wonder what the six could be.

The Mazda 626 came in around the same time as the 323, and was considered to be a moderately upscale compact with more flair and comfort than the 323. Just a few years later the Mazda 626 would be called Motor Trends import car of the year, and Mazda was definitely looking like they were going to be around for awhile. Now if a sport coupe was more to your liking then all you had to do was remove the last two numbers, and the Mazda 6 was the car for you.

The Mazda 6 was a rather nice performer compared to the previous 626, and could be woken up even more with its optional 2.2 liter turbo engine. Sold to the consumer at various trim levels the Mazda 6 definitely had a sporty feel; with a leather interior, 3-way adjustable suspension, ABS brakes, and electric sunroof the Mazda 6 was albeit not as sporty as the Mazda RX-7, but was definitely the next best thing. Now if ripping the streets is not your thing and an occasional romp through the trails is more your speed, then the Mazda tribute, which is actually based on the Mazda 626 platform, should be your weapon of choice.

The Mazda Tribute is a small crossover SUV, designed for the city folk with a country heart. With a four or six cylinder engine and firmer ride, the Tribute makes a great all around family transporter. But once again, Mazda did not quit here. Today's buyer now has the option of the all new Mazda CX-7, which is considered to be "the SUV you never saw coming". Sleek, Muscular, and performance car handling brings the CX-7 into the next millennium singing "Zoom, zoom, zoom" all the way to the grocery store!

Upgraded Mazda Rx-8, for the World to Experience

Mazda RX-8
Mazda has announced that its four-door sports car- RX-8 is now accepting orders through Mazda and Mazda Anfini dealers located in Japan. According to Mazda, sales transactions will commence on said state in mid-October this year.

Mazda RX-8 has been launched to the automotive world in April 2003. Since then, the company is receiving positive feedback from the customers. In view of giving better service and comfort to Mazda cars enthusiasts, an upgrade was made to said car model. The new version of Mazda RX-8 comes with a 6-speed automatic transmission to replace the former 4-speed slushbox.

Upgraded version of Mazda RX-8 assures the delivery of smooth acceleration plus improved noise reduction during high speeds. Aside from that, the 6-port design of its engine, which is 2-ports more that its previous model, augments intake efficiency.

Further, Mazda RX-8 has also added the all-new Active Adapt Shift (AAS) control which improves the pleasure of driving sports car. AAS is responsible for optimizing transmission shift points based on driver input using data from various sensors and vehicle handling. Moreover, AAS contribute to a more relaxing or more rugged driving depending on the driver's preference.

The new cog swapper is available in the base RX-8 and Type E models. Nonetheless, it is not available in Type S models with a 6-speed manual. The powerful 6-port rotary engine is incorporated in the 6-speed AT RX-8.

Mazda RX-8 Type S and Type E models can be ordered with a Sand Beige Leather Package. Said package complements the upholstery and trim of Mazda RX-8. On the exterior, 2 new body colors are introduced - the stark blue Stormy Blue Mica and radiant white Crystal White Pearl Mica. These colors are said to boost the sporty pedigree, identity and quality associated with Mazda RX-8 parts and vehicles.

Mazda RX-8 upgrade paved way for an enhanced sports car performance as well as overall quality. This car is now ready for the world to possess and enjoy.

Nemesis: The Mazda RX-8’s Third Special Ed

Mazda RX-8

The Nemesis is the name given to the Mazda RX-8 vehicle’s third special edition vehicle. Why third? Well, simply because this is the third special edition vehicle that has been built using the Mazda RX-8 which has been mainly known for its rotary powered engines.

According to the Mazda 808 parts manufacturer, this new Mazda RX-8 Nemesis special edition vehicle would still be created as a sports coupe that models four doors. They do further maintain that they had decided to build yet another special version because of the success of the two previous special edition vehicles for the Mazda RX-8 – the Evolve and the PZ.

So what should one expect from the Mazda RX-8? Mazda says that this vehicle would be coming with unique paint colors. The interior trim would also be colored in unique hues. Not too unique perhaps but simply unique enough in the world of automobiles. The Nemesis would also be having an exclusive accessory package which also comes with a really low price knowing that it is a special vehicle. How much? Well let us say that it is only priced at £22,995. And by looking at its price tag, you would now see that it is only some £330 less than the current Mazda RX-8 model.

Leather seats come as a natural for the Mazda RX-8 Nemesis. This vehicle also has been mounted with a five speed transmission system for a further boost in performance. Mazda even boasts that the Mazda RX-8 Nemesis has got a unique exterior and an even more unique interior. You can choose from two exclusive colors for the vehicle’s exterior. There is the Copper Red Mica and the Stormy Blue Mica. These are the only two color choices offered.

Alongside with that, you would find on the vehicle’s front air dam a polished aluminum Rotary crest. There are also aluminum side air outlet trims that have been thoroughly polished right behind the front wheel arches.

Inside the vehicle’s interior, the Mazda RX-8 Nemesis comes with special edition and very unique stone leather seat trims. There are also special and Nemesis branded luxury carpet mats.

Mazda RX-8 PZ: More Focused Coupe

Mazda RX-8
In response to customer feedback, Mazda has introduced a more focused version of its coupe – RX-8 PZ. The four-door sports coupe went on sale in the United Kingdom last July. From July Mazda RX-8 PZ has already established a good standing in both sales and reviews.

RX-8 PZ used some of the outstanding RX8 parts Mazda RX 8 and accessories to create the high-power version of the coupe. PZ has been developed through the collaboration of Mazda with Prodrive, a leading motorsport company.

Mazda’s agreement with Prodrive is to build a special car model that has the standard attributes of RX-8 without sacrificing the passenger’s comfort. Moreover, Prodrive developed bespoke suspension settings after conducting several extensive testing on selected roads and motorways. Another specification made by Prodrive is the lowering of the ride height by 15mm.

Aside from said special collaboration, Mazda also sought the help of specialist component suppliers like Eibach, Bilstein and OZ Racing. Top-quality components from the mentioned suppliers were used in manufacturing Mazda RX-8 PZ. This is to ensure exclusivity and power of the new vehicle.

The company also contemplated on reducing the roll and pitch and to making a flatter cornering attitude hence special Bilstein dampers and Eibach coil springs were used. Moreover, Prodrive specifications were satisfied. The spring rates were also increased by 60 percent and the mono-tube dampers were given tighter body control. However, the superb compliance over ridges and bumps in the road was maintained.

Mazda RX-8 PZ also comes with a bunch of unique features such as 18-inch OZ alloy wheels, rear silencer and aerodynamic rear spoiler, lowered suspension, grille mesh inserts on front and rear bumpers, door mirrors, and the one-of-a-kind 'Prodrive' badging. The distinguishing features of the latest of Mazda family include its color which is available in solid Brilliant Black and metallic Galaxy Grey. In addition, Mazda RX-8 PZ also features black leather seat trim, plus black leather-wrapped steering wheel, gear knob and hand-brake lever, which make it more classy and sophisticated.

Mazda RX8 Horsepower Controversy

Mazda RX-8
Since its launch, the Mazda RX8 has been the subject of close scrutiny by enthusiasts. The high level of attention is not only due to the car’s admirable driving dynamics but, in part to the early reports of below-than-expected performance. To be more specific: wheel horsepower measured on several chassis dynamometer runs resulted in values well below the expected 17%~20% drivetrain parasitic losses. And quarter mile runs of anywhere between 0.5 and 1.5 seconds off of those produced by magazines on allegedly pre-production vehicles.

In connection with the RX8’s horsepower rating: the original marketing material from Mazda North America (MNAO) advertised the 6 speed manual transmission RX8 at 247hp @ 8,500rpm. Assuming parasitic drivetrain loses between 17%-20% –common for modern rear wheel drive vehicles, a stock RX8 should measure between 205~197 horsepower at the rear wheels (rwhp) –depending on elevation, barometric pressure, temperature and correction factors applied. Instead, a stock RX8 chassis dyno run shows results ranging anywhere from mid-high ~160 to ~185rwhp. Such readings would represent parasitic drivetrain loses in excess of 25%. To say that, it is unacceptable to experience such a high level of loss through the drivetrain of a “sports car” with a carbon fiber drive shaft –amongst other things- is an understatement.

To further consolidate doubts about the actual power output of the new Renesis, several owners were unable to reproduce mid-low 14 second quarter mile passes -as seen published by well known U.S. car magazines. Low trap speeds were another hint towards the apparent lack of power output.

Shortly after, several debates on online enthusiast forums and discussion boards turned into heated arguments as to what was causing such poor "straight line performance." Many former Miata owners remembered a previous "snafu" in Mazda's history, when the manufacturer admittedly overstated the horsepower figures of their redesigned Mazda Miata.

After a few months, MNAO came forward and explained that they had misrepresented the Renesis' power output. The revised figure was now 238hp @ 8,500rpm; however, according to MNAO, this revision did not change the previously achieved track performance results.

Speculations about the reasons behind the sudden lack of power output were many. However, there are currently two schools of thought:


The first one supports the idea that the RX-8's engine management unit (ECU), in conjunction with the many "nanny" devices -such as ABS & TCS- do not allow to obtain accurate readings from a chassis dynamometer. To simplify, when the car is run on a chassis dyno, only the driven wheels are turning. The RX-8's ECU would detect an abnormal driving situation and retard timing and apply other safety measures to preserve either the "driver" or the "engine" -or both- from damage (read: skidding situation, or a car going out of the road.)
The second one believes that MNAO was forced to re-engineer the software that runs the engine management even before the first batch of RX-8's reached U.S. shores, due to upcoming Federal emissions regulations. I have read of one in particular, which requires catalytic converter lifespan of ~100,000 miles. The enemy number one of catalytic converters on any vehicle is heat (and heat is the number one attribute of rotary engine's exhaust gases.)

MNAO offered two options to those who had pre-ordered an RX-8, or had purchased no late than September 2003:


They would buy back the vehicle, no questions asked.
They would offer FREE Scheduled Maintenance for the life of the warranty, plus a 500 dollar "gift card" to those who opted to keep the car.

I was among those who opted to keep their RX-8. After all, the driving experience had not changed since test driving the vehicle prior to purchasing it. Since August 2003 I have clocked well over 20,000 miles -as of 1/18/2005- and I have but one ounce of regret about my decision. If you'd like to read more about owners' opinions, visit this thread @ RX8Club.com

There have been a number of ECU "updates" released during the past 2 years. To the best of my knowledge, all early samples of '04 RX-8s, came from port with level "J" of engine management software. Since then, we have escalated all the way through the alphabet to "M" -which was released on a TSB campaign by Mazda North America (MSP04) in order to have ALL vehicles taken in for Service @ Authorized Dealers flashed to "M" calibration.

ON THE ROAD MAZDA RX-8; Amazing, all-round Wankel winner

Hyper Sport Patrick Dempsey

THERE IS no other car quite like the Mazda RX-8. It has the singular body style to go with its singular engine, and it brings a whole new slant to the notion of a sporty GT coupe.

Its Audi arch-rival is a four-seater, but only just. The new Nissan 350Z and Chrysler Crossfire do not even attempt that feat. In the Mazda, though, we find not just a pair of habitable rear chairs but also dedicated doors through which to reach them. Mazda calls them "freestyle" doors; they are short and hinged on their rear edges, and have no pillar ahead of them against which to close.

Instead, they latch at the top and bottom of their front edges, to form the "pillars" against which the long front doors then shut. It is an inspired piece of packaging, but another piece of RX-8 is arguably even more inspired: its rotary engine.

This smooth-spinning, piston-less engine design, invented by German engineer Felix Wankel, was first used in an NSU sports car. It gained equal adulation and notoriety powering NSU's fabulous but flawed Ro80 saloon of 1967, a futuristic car whose warranty claims sunk its maker, but Mazda, which has made rotary-engined cars since 1967's Cosmo Sport 110S, rendered it reliable.

But Mazda could not solve the fuel thirst and noxious emissions, which is why the RX-7, descendant of a sports coupe line begun in the 1970s, was denied to Europe after 1997 although buyers on the Japanese home market could purchase one until last year.

Now, the RX-8's new "RENESIS" (Rotary Engine Genesis) engine has fixed the emissions and economy issues well enough to satisfy EC pollution police, and we can again enjoy an engine with less vibration than any other internal- combustion unit. Its two convex- triangular rotors sweep chambers with 1,308cc total volume, but because of the way the engine works this equates to 2,616cc of normal motor.

You can sense the difference as soon as you start it. The sound is halfway between a regular straight-six and a two-stroke engine without the pops and bangs. This Mazda comes with a choice of power outputs, the regular 192bhp matched to a five-speed gearbox (pounds 20,000) and the Hi-Power with 231bhp, xenon headlights with washers, aluminium pedals and, crucially, a six-speed gearbox. It costs an extra pounds 2,000, and is worth every penny.

I drove the 192bhp version first. It looks just like the more powerful RX-8 apart from the lack of headlamp washers, with front wheel arches so bold and a bonnet so tapered it almost seems to have the separate front wings of a pre-war sports car. And then there are the engine-rotor motifs, on the lower front air intake, the rear foglight, the holes in the headrests and on the gearlever. They are there to remind you; apparently, many American RX-7 owners did not even know their cars had rotary engines.

First, the downsides. The perforated sunvisors do not shield the sun well. The accelerator response can be snatchy, there is engine surge in traffic and occasionally the transmission clonks. Then, when you are out on a fast, open road you find the engine runs out of puff on hills so you have to downshift and rev it to oblivion.

But, on the bends, the RX-8 is total joy. The steering's response is instant and precise, a true mechanical connection to the front wheels without the initial uncertainty found in the Mazda's key rivals. The front wheels bite cleanly into the road, and you can power out of corners with that balanced, slingshot feeling only a powerful rear-wheel drive car can give. It also feels solid and well- made, so the firm suspension does not result in a turbulent ride. But should it not feel a little faster?

It should, which is why the Hi-Power is the RX-8 to have. The engine revs to crazy heights (well past 8,000rpm) and that extra gear exploits this broader rev-range. It does not matter that the engine speeds are higher because it is so smooth and musical, and the engine is never caught napping because there is always a suitable gear to keep it interested. I have not driven a more beguiling engine all year.

In every major way, this is the best of the new breed of sporty coupes. The driver of a grey-import RX-7, who followed me for miles before passing with a thumbs-up, thought so too.

Mazda Hits Home Run With RX-8 Styling, Price Point; - New Rotary-Powered RX-8 Is a Sports Car Like No Other -

Mazda RX-8 at Sendai Port
Mazda hit the sweet spot when it debuted the all-new, rotary-powered RX-8 sports car in January at the North American International Auto Show in Detroit. With an athletically sculpted exterior and one-of-a-kind rotary engine, the Mazda RX-8 is priced from $25,180 with a 210-horsepower engine and four-speed automatic transmission. Equipped with a 250-horsepower engine, six-speed manual transmission and 18-inch wheels and tires, the RX-8 is priced from $26,680. It is propelled by the all-new 13B RENESIS rotary engine and is the latest in a three-decade-long line of Mazda rotary-powered vehicles.

Mazda continues to pioneer cutting-edge styling with the RX-8's unique freestyle four-door design, effectively demonstrating that a true sports car does not need to sacrifice space or convenience. With enough passenger room for four full-size adults and enough trunk space to fit luggage for a weekend or two full-size golf bags, soulful driving is no longer solely for the driver.

Both automatic and manual transmission cars come equipped with power windows, mirrors and door locks, cruise control and an AM/FM/CD audio system with six speakers. To make ordering easy, both the automatic and manual are offered in four trim packages: a Base Model, Sport Package, Touring Package and Grand Touring Package. Priced from $1,100 for the manual transmission Sport Package to $4,600 for the automatic Grand Touring Package, they include accoutrements like Xenon headlights, Dynamic Stability Control with traction control, a BOSE(R) audio system, heated seats and leather trimmed upholstery.

The RX-8 delivers unprecedented sports car driving pleasure with the RENESIS rotary engine offering smooth, immediate power. Double wishbone front and multi-link rear suspension, complemented by electric power-assisted steering, yields razor sharp handling.

In addition to being the most revolutionary and cutting-edge sports car, the RX-8 is also one of the safest with standard features like ABS with Electronic Brake Distribution, front- and seat-mounted airbags as well as side air curtains. Mazda also incorporated high-strength steel construction for the side paneling and a special door-latch system in the freestyle door openings to create a solid exterior shell. The RX-8 is truly a sports car like no other at a value like no other.

The Mazda RX-8 comes with a four-year roadside assistance program. With a call to a toll-free number, RX-8 owners can access roadside assistance 24 hours a day, 365 days a year throughout the United States and Canada. For all 2003 Mazda vehicles, the company will provide a free loaner car in the event a warrantable condition requires alternative transportation.

The RX-8 is covered by a comprehensive four-year/50,000-mile warranty that covers every part on the vehicle except those subject to normal wear. In addition, the RX-8 is covered by a five-year/unlimited-mileage corrosion warranty.

Mazda North American Operations is responsible for the sales and marketing, customer parts and services support of Mazda vehicles in the United States.

Headquartered in Irvine, Calif., MNAO has more than 700 dealerships nationwide.

Mazda RX-8

Mazda RX-8

Mazda made its name in America in the early 1970s with a Wankel rotary engine propelling most of its cars. By 1973, they had climbed to fifth in U.S. sales with 92 percent of its 119,000 sales, rotary powered.

With its only major moving part a triangular rotor spinning in a cocoon-shaped combustion chamber through intake, compression, combustion and exhaust cycles, the rotary's appeal was a combination of compact size, smoothness, pleasing power and high-rpm zing. But it soon revealed a dark side: a &raking problem (fuel and oil consumption) combined with reliability, durability and emissions issues.

Bad word-of-mouth and the 73 fuel crisis squashed U.S. sales to 61,000 in 1974, but the company moved quickly to proliferate piston power through its line while improving the rotary for performance models, striking gold in 1979 with the RX-7 sports car, the most successful model in IMSA racing history. Rotary-powered prototypes scored U.S. and international victories including the 1991 24-Hours of LeMan. But when Mazda dropped its third-generation RX-7 in the mid-'90s, the rotary was history.

Or was it? The '03 debut of Mazda's RX-8 4-seat sportster marked the rotary's return in much-improved form after an 8-year hiatus. The 1.3L two-rotor RENESIS (Rotary-Engine Genesis) engine pumps 238 eager horses through a 6-speed manual, or 197 through a 4speed automatic. The car's shape is sinuously sexy, its front-facing rear doors and pillarless body offer easy access to a reasonable rear cabin, and its front mid-engine/RWD layout gives a low center of gravity and perfect 50/50 weight distribution for racer-like handling.

At roughly $27,000 and 18/24-mpg economy, the RX-8 still imbibes too much gas and (according to owners) oil as part of its unique character. But it's a genuine driver's delight.

MAZDA RX-8: THE ROTARY REVOLUTION ROLLS ON

Mazda RX-8

High-powered, lightweight and perfectly balanced for nimble handling and supreme control, the Mazda RX-8 is unlike any other sports car in the world. From the industry’s only rotary engine to the innovative free-style doors, the RX-8 is a sports car like no other.

The 2007 model-year edition continues to push the parameters of the sports car segment, this year with only minor updates. New for 2007, the Grand Touring model offers available Sand leather-trimmed seats, while the Touring and the Grand Touring models add a standard 6-disc CD changer. Two new exterior colors are available on all 2007 RX-8 models – Crystal White Pearl and Stormy Blue Mica.

“Since its creation, the RX-8 has continued to win rave reviews from the automotive press,” said Tetsu Nakazawa, RX-8 vehicle line manager. “The RX-8 is a sports car built for the real world; ideal for zooming around a track, but equally suitable for taking the kids to soccer practice. It is a true sports car that can pull double duty."

The 2007 Mazda RX-8 is available as either a 232-horsepower model fitted with a six-speed manual transmission, or a 212-horsepower model fitted with a six-speed automatic with steering- wheel-mounted paddle shifters for a Formula 1-style driving experience (the change in

horsepower ratings from 2006 is due to the new SAE rating standards). Both automatic and manual transmission cars come equipped with power windows, mirrors and door locks, cruise control and an AM/FM/CD audio system with six speakers.

RENESIS ROTARY ENGINE

The lifeline of this powerfully agile sports car rests underneath the hood thanks to its advanced RENESIS ( Rotary Engine ge nesis – or rebirth of the rotary engine) engine. The Mazda RX-8 remains the only mass produced rotary-powered passenger car in the world.

By turning a triangular rotor in a cocoon-shaped combustion chamber, the RX-8’s rotary engine efficiently performs the four processes of intake, compression, combustion and exhaust. The RENESIS engine is remarkably smooth and high revving — all the way to 9,000 rpm (7,500 rpm on Sport A/T–equipped models) — and offers a smaller engine footprint than traditional internal combustion engines (some 60 percent smaller and lighter than a comparably powered V-6, and 40 percent smaller and lighter than a four-cylinder). In fact, the packaging and styling that define the RX-8 would not have been possible had Mazda engineers chosen a conventional piston engine.

Improving upon 40 years of rotary designs, the RENESIS engine features side intake and exhaust ports with nearly 30 percent more intake area and twice as much exhaust area than its predecessors. The efficiencies gained through larger intake and exhaust ports exclude the need for forced induction.

The RX-8’s normally aspirated 1.3-liter engine might appear diminutive to the untrained eye when compared to large-displacement V-8s or heavyweight V-10s or

V-12s. However, through the incredible efficiencies of a rotary powerplant, an advanced three-stage intake system and an electronic throttle, the RENESIS engine delivers smooth, linear power on a grand scale. The 2007 RX-8 does not sacrifice emissions for power, though. Through improvements to the

port design, overlap between the intake and exhaust ports has been eliminated, significantly reducing exhaust emissions, improving fuel economy and allowing the car to meet the strict Tier2 Bin 5 Federal emissions classification. The effort made by Mazda engineers to improve emissions is a prime example of the concern for environmental impact maintained throughout the development process.

By placing the powerplant low and far back in the engine bay, in what Mazda calls an advanced front-midship layout, the center of gravity is lowered, which in turn improves vehicle balance. In addition, the fuel tank is placed ahead of the rear axle, and all seating is within the wheelbase and track of the car. Combined, these factors contribute to a perfect 50/50 vehicle weight distribution, low yaw-inertia movement and superb handling characteristics. With such excellent balance, it is little wonder the RX-8 feels right at home on the twists and turns of Mazda Raceway Laguna Seca, negotiating a tight freeway onramp or in stop-and-go traffic.

A RACE CAR AT HEART

The RX-8’s demeanor on the track is not overlooked by the motorsports community. The same RENESIS engine found in production RX-8s is used in the professional Formula Mazda series, a popular open-wheel racing series run on the nation’s most demanding race tracks. Formula Mazda is widely regarded as a training ground for developing drivers looking to build a career in motorsports. The fact that the series uses a showroom-stock, non-modified RENESIS engine is a testament to the power, reliability and light-weight of the RX-8 powerplant.

The RX-8 also campaigns in the Grand American Road Racing Association’s Grand Am Cup Street Tuner (ST) division. The ST division consists of production cars driven straight from the showroom to the race track with limited racing modification. Here, the superb handling characteristics and near-bulletproof RENESIS engine already have taken the RX-8 to victory circle many times, including the 2005 drivers’ and manufacturers’ championships, and all indications point to many happy returns.

SUSPENSION AND STEERING

The RX-8 uses an aluminum double-wishbone front suspension, reducing unsprung weight over the use of steel components. By mounting the upper and lower arms on a highly rigid sub-frame, the long arms ensure linear alignment changes throughout the jounce and rebound of the front wheels. All wheels receive mono-tube gas-filled shock absorbers designed with large-diameter internal pistons and valving, which offer excellent road feedback and a smooth ride.

An electric rack-and-pinion power-steering system transmits just the right amount of road information back to the driver. Mazda engineers have chosen to pursue their own path by using an electric motor for steering assistance rather than a conventional power-steering pump. The electric motor provides additional assistance at low speeds to ease parking and reduces steering assistance at higher speeds to provide greater road feel, responsiveness and feedback. And, in keeping with the rest of the development on RX-8, it is far lighter and easier to package than a conventional power-steering rack.

PRACTICAL STYLING

The RX-8’s unique “freestyle” four-door design is proof that a true sports car does not need to sacrifice space or convenience for performance. The advanced design of the rear-hinged rear doors, provides a large door opening, allowing adult-sized passengers to easily enter and exit the vehicle. This design is also advantageous when securing a baby or a small child in the back seat. With a spacious rear seat area providing ample passenger room for four full-size adults, and enough trunk space for a weekend’s worth of luggage, this sports car proves its versatility.

Taut muscular lines give RX-8 the liberating look of an athlete in motion. The muscular styling maintains classic sports car proportions while adding a Zoom-Zoom edge that is unmistakably Mazda. Integrated throughout the exterior is the unique triangular rotor design, which clearly can be seen in the front fascia, head lamps, hood and rear bumper valence.

The RX-8’s exterior styling presents a genuine sports car form, while the interior boasts a comfortable and intelligently designed cabin. An extremely low cabin floor allows the seats to be mounted low in the chassis, which, along with a low instrument cluster and hood, enhance driver visibility. Mazda designers concentrated on the shape of the front seat backs and the rear seat cushions to ensure adequate rear-seat knee room. Front seat slide-rails are positioned to allow maximum leg room for rear-seat passengers.

The rotary design element is incorporated through the interior of the RX-8 in creative ways, appearing in the seats, center console, shift knob and emergency brake. The stylish cabin also evokes a sense of luxury and high-end quality. Mazda’s design team examined every aspect and component of the interior and has created an elegant, driver-centric atmosphere. Through the use of advanced ergonomic research, Mazda engineers established improper seating posture to be a cause of driver fatigue and built in optimum support in the front seats to help offset discomfort. In addition, the soft blue lighting used in the RX-8’s instrument cluster was found to reduce eye fatigue and strain.

SUPERIOR SAFETY

When designing the RX-8, safety was given as much of a priority as was performance. For Mazda, the safety process incorporates both accident avoidance and accident protection. In effect, this approach to safety means the RX-8 can help the driver avoid various dangers and protect occupants in the unfortunate event of a collision. In rollover tests performed by the National Highway Traffic Safety Administration (NHTSA), the RX-8 achieved an impressive five-star rating.

Mazda engineers integrated numerous active and passive safety elements throughout the car. Active safety features, which require input from the driver, include the use of large ABS-equipped disc brakes on all wheels as well as precise steering and suspension systems. Dynamic Stability Control (standard on manual transmission cars with Sport Package, optional on RX-8s with automatic transmissions) delivers a superior level of handling that can be disabled when driving and road conditions allow safe operation.

Passive systems, or those that take effect automatically without the driver’s involvement, also are present throughout the RX-8. Despite the absence of a center B-pillar, the RX-8 has an exceptionally rigid body, accomplished through the use of a series of locking pins, which hold the doors together and bind each door directly into the roof and floor. Integrating the frame components helps dissipate crash energy through the vehicle’s structure.

Other standard passive systems on the RX-8 include front airbags, seat-mounted side-impact airbags and side-curtain airbags. Additionally, the front end and engine bay have ample crumple zones, the front seats are designed to reduce whiplash injuries, the brake pedal is designed to break away in the event of a collision of sufficient force to protect feet and legs and all four seating positions are fitted with three-point seatbelts. Even pedestrian protection was considered, as the RX-8 is fitted with Mazda’s "shock-cone" hood design that yields more to the impact of a pedestrian onto the hood than a standard design, yet is strong enough to not deform in normal use.


MAZDA RX-8 INTRODUCES NEW R3 HANDLING PACKAGE

Mazda RX-8
Mazda North American Operations today announced the first shipments of 2009 RX-8 sports coupes are being released to dealers across North America, and will soon be in showrooms.

For 2009, Mazda will further the evolution of the four-door, four-seat sports coupe, giving RX-8 a refreshed exterior and interior design, enhanced performance and a new R3 sport package for the ultimate driving enthusiast. Unchanged is the core of the RX-8 – a high-powered, lightweight and perfectly balanced machine powered by the world-renowned twin-rotor RENESIS rotary engine.

To enhance the highly successful RX-8, Mazda engineers focused on innovation in three key areas for the 2009 RX-8: styling, performance and packaging.

Refinements for the 2009 model year include restyled front and rear bumpers and front fascia; sporty, high quality-finish front and rear lamps; and larger exhaust pipes. The 2009 RX-8 also offers a new five-spoke wheel featuring a symbolic and sporty design reminiscent of the rotary engine, with different arrangements for each wheel size.

Interior enhancements include redesigning the center instrument panel shape to give a feeling of dynamic movement. Additionally, a variable red-zone was added to the tachometer that rises as the engine comes to operating temperature, and a new steering wheel and redesigned front and rear seats add to the experience.

Through-and-through, the RX-8 is a pure sports car that gives the driver an exciting and dynamic experience. For 2009, engineers improved RX-8 body rigidity through the addition of structural reinforcements, by adding a trapezoidal strut tower bar and enhancing the local rigidity of the front suspension tower areas. Also, the rear suspension geometry has been reconfigured for better handling performance and driveshaft rigidity is improved, lowering NVH levels and improving performance.

Raising RX-8’s dynamics up a notch is the new R3 sport package. Providing the very best in rotary-powered motoring, the R3 harkens back to the R1 and R2 packages offered on the mighty third-generation RX-7, and adds a sport-tuned suspension with Bilstein shock absorbers and front suspension crossmembers filled with urethane foam. Filling the crossmembers makes for a smoother ride, minimized NVH and greater suspension control.

On the visual side of the package, a rear spoiler, side sills, fog lights and sporty front bumper are added to give an aggressive appearance, along with 19-inch forged aluminum-alloy wheels with high performance tires. Inside, the R3 adds a 300-watt BOSE® audio system with Centerpoint® surround sound and AudioPilot® noise compensation technology, Bluetooth hands-free phone system, front Recaro sport seats with leather side bolsters, leather-wrapped parking brake handle and Mazda advanced keyless entry and start system.

When the first 2009 RX-8s arrive at dealers, customers also will find an extension to Mazda’s warranty, extending coverage on the unique rotary engine to eight years/100,000 miles (whichever comes first). The balance of the powertrain warranty remains at five years/60,000 miles, and the basic warranty at three years/36,000 miles.

The warranty extension is proof of the company’s faith in the rotary engine, a hallmark of Mazda’s engineering leadership since 1967 when it first appeared in the Cosmo Sport 110S. Additionally, Mazda will extend this eight year/100,000 mile warranty retroactively to all existing 2004-2008 model year RX-8s – again, to show their support of the longevity of the engine. Customers with questions regarding the warranty should contact their local Mazda dealership or the Mazda Customer Assistance Center at 1-800-222-5500. All existing RX-8 customers were contacted directly by Mazda to notify them of this warranty change, beginning on May 30, 2008.

Headquartered in Irvine, Calif., Mazda North American Operations oversees the sales, marketing, parts and customer service support of Mazda vehicles in the United States, Canada and Mexico through nearly 900 dealers. Operations in Canada are managed by Mazda Canada, Inc., located in Ontario, Canada, and in Mexico by Mazda Motor de Mexico in Mexico City.

Mazda RX-8: Mass Production Revolution Rolls On

Mazda RX-8

Mazda is offering something big in its new lineup. It includes all-new RX-8 that is made more powerful and lightweight. The release of said models has introduced it to be a sports car like no other.

Tetsu Nakazawa, RX-8 vehicle line manager, “Since its creation, the RX-8 has continued to win rave reviews from the automotive press. The RX-8 is a sports car built for the real world, ideal for zooming around a track, but equally suitable for taking the kids to soccer practice. It is a true sports car that can pull double duty."

2007 Mazda RX-8 is available as a 232-horsepower model engineered with a six-speed manual transmission or a 212-horsepower model engineered with a six-speed automatic with steering- wheel-mounted paddle shifters for a drive feel that is similar to that of Formula 1-style. Both cars are equipped with power door locks, mirrors, cruise control and an AM/FM/CD audio system with 6 speakers. Basically, most of these power parts are based from 1981 Mazda RX-7 parts only that they were upgraded and modified to come up with something better.

Underneath Mazda RX-8 is a race car character wraps in a sleek sports car. Its groundbreaking Rotary Engine Genesis engine (RENESIS) also known as the rebirth rotary engine is a product of meticulous design, engineering and manufacturing processes. In fact, it is the only rotary-powered passenger car around the globe which is mass produced. The engine is capable of efficiently performing the four essential processes crucial to keep the car powerful and agile.

Mazda RX-8 has a muscular built and a unique 'freestyle' design. It aims to prove that true sports car does need not compromise the space, convenience and comfort. Mazda engineers have designed the latest addition to exude versatility, style, performance and safety. In fact, they have integrated in the car several active and passive safety elements.

Active safety elements include the use of big ABS-equipped disc brakes on all wheels, accurate steering, Dynamic Stability Control and suspension systems. On the other hand, passive safety elements consist of the front airbags, seat-mounted side-curtain airbags and side-impact airbags. Furthermore, the front end and engine bay have ample crumple zones and the front seats are designed to diminish whiplash injuries.

Mazda RX8 Horsepower Controversy


Since its launch, the Mazda RX8 has been the subject of close scrutiny by enthusiasts. The high level of attention is not only due to the car’s admirable driving dynamics but, in part to the early reports of below-than-expected performance. To be more specific: wheel horsepower measured on several chassis dynamometer runs resulted in values well below the expected 17%~20% drivetrain parasitic losses. And quarter mile runs of anywhere between 0.5 and 1.5 seconds off of those produced by magazines on allegedly pre-production vehicles.

In connection with the RX-8’s horsepower rating: the original marketing material from Mazda North America (MNAO) advertised the 6 speed manual transmission RX8 at 247hp @ 8,500rpm. Assuming parasitic drivetrain loses between 17%-20% –common for modern rear wheel drive vehicles, a stock Mazda RX-8 should measure between 205~197 horsepower at the rear wheels (rwhp) –depending on elevation, barometric pressure, temperature and correction factors applied. Instead, a stock RX-8 chassis dyno run shows results ranging anywhere from mid-high ~160 to ~185rwhp. Such readings would represent parasitic drivetrain loses in excess of 25%. To say that, it is unacceptable to experience such a high level of loss through the drivetrain of a “sports car” with a carbon fiber drive shaft –amongst other things- is an understatement.

To further consolidate doubts about the actual power output of the new Renesis, several Mazda RX-8 owners were unable to reproduce mid-low 14 second quarter mile passes -as seen published by well known U.S. car magazines. Low trap speeds were another hint towards the apparent lack of power output.

Shortly after, several debates on online enthusiast forums and discussion boards turned into heated arguments as to what was causing such poor "straight line performance." Many former Miata owners remembered a previous "snafu" in Mazda's history, when the manufacturer admittedly overstated the horsepower figures of their redesigned Mazda Miata.

After a few months, MNAO came forward and explained that they had misrepresented the Renesis' power output. The revised figure was now 238hp @ 8,500rpm; however, according to MNAO, this revision did not change the previously achieved track performance results.

Speculations about the reasons behind the sudden lack of power output were many. However, there are currently two schools of thought:

* The first one supports the idea that the RX-8's engine management unit (ECU), in conjunction with the many "nanny" devices -such as ABS & TCS- do not allow to obtain accurate readings from a chassis dynamometer. To simplify, when the car is run on a chassis dyno, only the driven wheels are turning. The RX-8's ECU would detect an abnormal driving situation and retard timing and apply other safety measures to preserve either the "driver" or the "engine" -or both- from damage (read: skidding situation, or a car going out of the road.)
* The second one believes that MNAO was forced to re-engineer the software that runs the engine management even before the first batch of RX-8's reached U.S. shores, due to upcoming Federal emissions regulations. I have read of one in particular, which requires catalytic converter lifespan of ~100,000 miles. The enemy number one of catalytic converters on any vehicle is heat (and heat is the number one attribute of rotary engine's exhaust gases.)

MNAO offered two options to those who had pre-ordered an RX-8, or had purchased no late than September 2003:

* They would buy back the vehicle, no questions asked.
* They would offer FREE Scheduled Maintenance for the life of the warranty, plus a 500 dollar "gift card" to those who opted to keep the car.

I was among those who opted to keep their RX-8. After all, the driving experience had not changed since test driving the vehicle prior to purchasing it. Since August 2003 I have clocked well over 20,000 miles -as of 1/18/2005- and I have but one ounce of regret about my decision. If you'd like to read more about owners' opinions, visit this thread @ RX8Club.com

There have been a number of ECU "updates" released during the past 2 years. To the best of my knowledge, all early samples of '04 RX-8s, came from port with level "J" of engine management software. Since then, we have escalated all the way through the alphabet to "M" -which was released on a TSB campaign by Mazda North America (MSP04) in order to have ALL vehicles taken in for Service @ Authorized Dealers flashed to "M" calibration.

Sumitomo HTR+ Review on a Mazda RX8

I was forced to start looking at potential replacements for the stock Bridgestone Potenza RE040 (225/45/18) slightly after hitting 25,000 miles on them. I was hard pressed by economic reasons to find the cheapest possible tires that would offer a similar or higher tread life (higher was better) and a decent level of performance on dry surfaces, as well as wet. I eliminated a few candidates before settling for the Sumitomo HTRs, namely:

  • Fuzion ZRi: Funky looking tread pattern. In other words, all-show-no-go.
  • Yokohama AVS ES100: Pretty decent reviews overall, but...heck! ended up over budget!
  • Dunlop SP Sport FM901: Had mixed feelings about these, and some pointed to another flavor of Fuzion 'philosophy.'
  • Nitto NT555: These tires received good reviews overall from the quarter mile crowd, which didn't quite say much about the tire ability to turn...so, discarded.
  • Sumitomo HTR Z II: Out of stock!Mazda RX-8

So after a brief discussion with a TireRack sales guy, he recommended the Sumitomo HTR+. First I was hesitant to go for an all-season tire. I thought to myself "All seasons on the 8? No way! But slowly I realized that I didn't have much of a choice in the price range I was shopping in. And so I ended up shelling out my credit card to purchase a set of 4 Sumitomo HTR+ in 245/40/18. The rolling stock ends up being something close to
1% bigger than the stock Potenzas. In other words, no big deal.

My first impressions

I got the tires installed and the suspension checked and aligned at Christensen Tire, here in Richardson. In all, the entire install took the a couple hours. I immediately jumped back in the car and drove off. The first thing I noticed was the engine and exhaust note -I am running on a completely stock Mazda RX8. And I could actually appreciate the engine reving up and down over the tire noise. Let me take that back: What tire noise? So, the first impression was a nice one.

However, happiness only lasted one corner. The first time I had to turn, I noticed a tremendous mushiness(sp) on the steering. On my way home, I kept praying for the tire pressure to be extremely low, therefore giving that soft feeling. Well, tire pressure was not it, I checked all 4 cornerns and all 4 were pinned @ 39psi. The tires were actually over-inflated from recommended pressure. The responsible was obviously a very soft and tall sidewall. There is a superimposed photo of the Sumitomos and the Potenzas below. You can see that both tires have similar "total" height when mounted; however, the Potenzas had a slightly rounded sidewall, and a much better lip to protect the wheels. On the other hand, the Sumitomos have a straighter(sp) sidewall, which apparently robs it from stifness.

I will try and rotate these tires every 5,000 miles. Reason being, on the last Potenza rotation, the tires that spent the last 7,500 miles on the rear were badly worn out (evenly worn though). And I'd like to keep the Sumitomos in the best shape possible.

Mazda Gives Tips for Hot Summer Driving, Riding

Mazda RX-8
Mazda North American Operations (MNAO) is the maker of the MX-5 Miata - the best-selling convertible sports car in the planet, and the only optional power-retractable hard top that consumes no trunk space. It celebrates the mark of the unofficial start of summer driving through offering some driving tips for the season to assure convertible drivers all over the United States safely enjoy their vehicles.

Very different from other authorized organizations, their tips encompass humans as the subject and not the car.

Their recommended daily routine with the car are as follows:

• For the human skin, at least SPF 15 sunscreen rating should be applied. A sun exposure of 15 minutes per day is tantamount to 90 hours per year of incidental sun exposure.

• While driving or riding in a convertible, always pony your hair to prevent wind damage and dry hair. You may also wrap your hair in a bun or use a hat. Also, make sure to always bring extra hair products – hairpins, butterfly clamps or rubber bands.

• Wearing sunglasses will help prevent too much of the sun’s heat from entering your eyes. Always wear them also to protect your eyes from airborne debris.

• When driving with top down or low windows, avoid leaving loose sheets of papers, pieces of light clothing, or plastics. These things will surely be driven by the wind. In effect, you are adding to the deterioration of the ecosystem.

• If you want to leave the roof down, do not park near trees to pave way for the birds’ resting area.

• Before opening or closing the top, pull over and have a complete stop. Aside from an unsafe distraction, the parts that control the top may be damaged by the wind.

• To avoid dryness or dehydration, drinking plenty of water is recommended. A moisturizer and a lip balm can also be a remedy.

• And above all, always ensure safety regardless of the length of the trip.

Jim O’Sullivan, President and CEO of MNAO, said that the MX-5 Miata is the most sold convertible sports car all over the world with over 800,000 units sold. And according to him only Mazda has the authority “to speak on behalf of top-down, wind-in-your-hair, and sun-on-your’s-face driving fun”. Summer road trips will be seen any time from now. With this, O’Sullivan said everyone must keep those road tips in mind.

With top of the line Mazda engine, MX-5 Miata pricing starts at $20,435 (MSRP). This convertible has up to 30 mpg on the highway and an open-top motor with minimal wind turbulence in the cabin.

An aero-board wind deflator is found between the seat backs. This guides forward flowing air to go upward. This deflator was invented by Mazda on the 1987 RX-7 Convertible but is now common on modern convertibles.

Aside form the MX-5 Miata convertible, Mazda builds other vehicles that offer optional sunroofs. These vehicles are the RX-8 sports car, MAZDA3, MAZDA5, MAZDA6, CX-7, CX-9 and the Tribute.

O’Sullivan added that driving a Mazda means a wonderful trip.

Mazda Launches Revised Rx-8

Mazda RX-8
The Mazda Motor Corp. has launched its four-door, four-seater sports coupe RX-8 at this year’s North American International Auto Show with a serious bang. The new generation coupe boasts of a refreshed styling and an improved performance to wow more auto enthusiasts.

The Japanese automaker restyled the front and rear bumpers, wheels, headlights, and LED taillights while retaining the traditional rear-hinged rear doors. What is more, the automaker made the exhaust pipes and alloy wheels bigger than the previous model.

The RX-8 entertained a stiffened body by using a bar between the front suspension towers. Aside from enhancing stability of the car, it is also resorted to improve handling. The gearing was also modified to make the car even faster.

"Dating back to the Cosmo Sport released in 1967, every sports car ever developed by Mazda has had the same fundamental mission - to provide car lovers with a vehicle that's fun-to-drive, exciting to look at and easy to own," said Tetsu Nakazawa, Mazda North American Operations' RX-8 vehicle line manager. "The new RX-8 embodies that mission, conveying the unique and distinctive Mazda brand DNA to the fullest."

To make the revision catchier, Mazda’s pool of engineers zeroed in on innovation in three areas – styling, packaging and performance. "The enhancements made to RX-8's exterior, interior, packaging and performance takes it to a whole new level of visual and driving excitement," added Nakazawa.

Also, a flagship new sport package of the car will also be available. This will include a sport-tuned suspension, a body kit (with a new front bumper and side sills as well as fog lights and high-performance tyres) and Recaro front seats with leather side bolsters, reported Reuters.

The revised models are expected to go on sale in the United Kingdom in the summer. According to the maker of Mazda spark plugs, prices and specifications will be announced nearer the time.

Separately, Mazda will be entertaining the use of new skins to lure more shoppers. Because it still takes four to five years to create a new car, there is a gap before the design themes reach production, said Franz von Holzhausen, the director of design for Mazda North American Operations.

"You will see this design philosophy in the future," von Holzhausen said last Wednesday at the AutoWeek Design Forum. “If Mazda doesn't evolve and reinvent its "skin," it runs the risk of becoming obsolete. Look at BMW. They recreated their skin. It was controversial but now they are selling more cars because of it.”

Why You Should Always Seek Genuine Mazda Auto Parts

Mazda RX-8

Mazda automobiles are well known for their classy styles and cool sports cars. Many people have longed to own one of these beauties. They imagine themselves zipping down a highway at break neck speeds or slowly cruising through town, making sure that everyone sees and admires them. When it's time to find replacement parts for the Mazda, many people will look around, hoping to find some that will properly fix their cars. One of the best ways to find them is by visiting one of the many online automotive stores.

Many online automotive parts stores, in an effort to provide consumers with more choices for high caliber backup parts for repairing, replacement, or customization, now offer a more extensive line of Mazda parts. The Mazda parts they offer range from high quality body/frame parts, car lamps, and other vehicles accessories. These parts, and many more, are produced by world-class auto parts manufacturers. This means that every part that passes through the assembly line has also passed strict quality assurance tests.

Vehicle parts, like the Mazda 626 alternator, radiators, fuel tanks, pickup engine parts, bumpers, tail lamps, and the mirror for the Miata are crucial to your vehicle's effectiveness. This means that replacing your car parts with high grade Mazda components is an absolute necessity. Some auto parts stores will offer you super sweet deals on low cost Mazda parts; unfortunately these parts aren't as efficient as the original equipment manufacturer parts. Getting your OEM parts from an online store that specializes in Mazda parts, is a great way to outfit your car with parts you can depend on.Mazda RX-8

The Mazda Miata engine parts, like the alternator, are very important to the automobile's effectiveness, because the alternator creates the electricity your car needs to operate; charging the battery and allowing the vehicle to start. Buying a Mazda RX-8 radiator is also very important since this particular component is responsible for the minimizing of the heat taken in by the engine while the car is running. If your car didn't have a radiator, your vehicle would overheat and break down on you.

Replacement exterior parts for your Mazda: Miata hoods, the RX-8 front bumper, 323 front fenders, need to be super strong and durable because they are crucial to the driver's safety. Your vehicle's hood offers protection for the engine and other vital car parts beneath it. Also, the carbon fibers of the hood boost your vehicles acceleration capabilities because it weighs less and is more aerodynamic. The quality of the fender and bumpers should also be a priority to the Mazda consumer. The vehicle's fender helps keep you safe by absorbing the impact of an accident. Frequently, the fender gets too mangled during an accident to be useful anymore. These parts are easily replaced, but you need to replace them with durable replacement parts to insure that you are completely protected in the future.

Zooming With the 2007 Mazda Rx 8 Gt

Mazda RX-8
The Mazda RX8 GT is a sports car and it may have been created to be such but it is yet an extraordinary sports car. This Mazda RX8 GT has already got proof of just how much of a sports car it can be for it has already been the recipient of various awards which even include the Car of the Year award for the year 2003 from Wheels magazine. A year after that, the vehicle also was recognized as one great sports car when it was nominated for the North American Car of the Year award but as luck would have it, it was not able to take home the prize. For three consecutive years starting 2004, the Mazda RX 8 GT also became listed and recognized as one of the best cars in the Car and Driver magazine's Ten Best vehicle list.

The Mazda RX8 GT was also made popular when it was used for a couple of events that included the media. If you would go back to history, you would know that back in 2004, the Mazda RX 8 GT was used in a racing series, the Formula Woman. And if you can watch the 2003 movie X2: X-Men United, you would also be able to catch a glimpse of this sports car there.

A RENESIS rotary engine is the source of power behind this sports car and the Mazda MPV auto parts creator does say that such an engine has differentiated this vehicle from the rest of the sports cars and wannabe sports cars on the road. This engine may be small and could seem to be harmless, however, this 1.3 liter rotary engine has got the right kind of performance and power to make the 2007 Mazda RX 8 GT zoom by you. It has been designed to actually create some 232 units of horsepower and along with that some 159 foot pounds of torque for the rear wheels to give the vehicle a further boost in speed.

On the downside, you may want to reconsider owning a sports car such as this if you do not have enough budget for a vehicle that guzzles gas like water. You see, for city driving, you can only get an average of 12.8 liters per 100 kilometers while highway driving could give you only 9.2.

2009 Mazda RX-8 Preview

Mazda RX-8 R3
A refresh and some additional features for Mazda's rotary-powered RX-8 will see it enter the 2009 model year with a sharpened look and the addition of an enhanced performance model. RX-8 is a popular car for shoppers after the racy looks and performance of a coupe, coupled with the added utility and sensibility of a four-door. It's powered by Mazda's unconventional rotary "Renesis" engine, which displaces just 1.3 litres but generates up to 232 horsepower.

Three models comprise the RX-8 lineup: the base "GS", the mid-range "GT" and the new, specially tuned "R3". Standard equipment across the RX-8 lineup has been expanded to include a full suite of high-tech, automatic gadgets like automatic lights, an auto-dimming rearview mirror, an intelligent key system and automatic climate control. Rain sensing wipers are standard as well.

Shoppers will also find MP3 compatibility across the lineup, as well as an alarm system and an enlarged fuel tank that's now good to store 64 litres of premium.

Stepping up to the GT model adds a powered, memory driver's seat, Bluetooth capability, integrated satellite radio, moonroof and push-button front-seat sliding for rear-seat entry. GT models also benefit from black, red or beige leather seating surfaces.

For added performance and killer looks, Mazda's introducing an RX-8 R3 model to their lineup as well. The R3 designated model offers the same features as the GT, but adds a sportier front bumper, side skirts, a raised spoiler and 19-inch wheels. Lightweight Recaro seats are fitted inside, and a performance-tuned Bilstein suspension system helps the R3 clamp down on the pavement. Xenon HID lighting and special leather trim and stitching inside help to complete the package for owners who want a bit more attitude and performance from their RX-8.

In any case, the four-door coupe is powered by a 1.3 liter, multi-side-port rotary engine that develops 212 horsepower when hooked up to the 6-speed automatic transmission, or 232 when twisting the six-speed manual. The automatic gearbox features paddle-shifters on the steering wheel for added driver control, while the slick manual gearbox offers 'flick of the wrist' gear changes with its short-throw shifter.

The rotary engine is characterized by its unique sound, smooth power curve free-revving character. With the six-speed manual gearbox, the RX-8 redlines at a shrieking 9000 rpm, while dashing to 100 km/h in about six seconds. Of course, powerful four-wheel disc brakes are fitted for gut-wrenching stopping power to back up the acceleration. Antilock and brake force distribution are standard.

MAZDA RX-8 HYDROGEN ROTARY ENGINE: A SPORTS CAR (AND ENGINE) LIKE NO OTHER

With a cat-like predatory stance, forward-thinking freestyle door system and enough room for four, not two, adults to enjoy all its benefits, the Mazda RX-8 has set itself apart from the pack. But if the recently introduced RX-8 production sports car truly is unique thanks, in large part, to its rotary engine, the RX-8 Hydrogen Rotary Engine (RE) concept, showcased this year at the North American International Auto Show (NAIAS), takes "unique" to all new levels.


Featuring a fuel system that consists of a high-pressure hydrogen tank, the Mazda RX-8 balances the needs of the driving enthusiast and the environmentalist with a blend of alternative power and the exhilarating driving experience for which Mazda is known.



As the auto industry turns its attention to hydrogen fuel as a gasoline alternative, the RX-8 Hydrogen RE offers a hydrogen-powered version of RENESIS—Mazda’s next generation rotary engine that was introduced last year in the all-new RX-8. By virtue of its smooth performance, compact size and impressive driving characteristics, RENESIS was named International Engine of the Year in June 2003.



The RENESIS Hydrogen RE allows the RX-8 concept to run on either hydrogen fuel or gasoline and capitalizes on all the advantages of the rotary to assure RX-8’s ease-of-operation and reliability.



The RENESIS Hydrogen RE incorporates an electronically controlled hydrogen injector system, with the hydrogen injected in a gaseous state. The system draws air from the side port during the intake cycle and uses dual hydrogen injectors in each of the engine’s twin rotor housings to directly inject hydrogen into the intake chambers.



Because it offers separate chambers for intake and combustion, the rotary engine is ideal for burning hydrogen without the backfiring that can occur in a traditional piston engine. The separate induction chamber also provides a safer temperature for fitting the dual hydrogen injectors with their rubber seals, which are susceptible to the high temperatures encountered in a conventional reciprocating piston engine.



Also helping to maximize the benefits of the rotary engine in hydrogen combustion mode, the RENESIS Hydrogen RE features adequate space for the installation of two injectors per intake chamber. Because hydrogen has an extremely low density, a much greater injection volume is required compared with gasoline, thus demanding the use of more than one injector. Typically, this can be difficult to achieve with a conventional reciprocating piston engine because of the structural constraints that prevent mounting injectors in the combustion chamber. However, with its twin hydrogen injectors, the RENESIS Hydrogen RE is both practical and able to deliver sufficient power.



In addition to the revolutionary hydrogen-powered RENESIS rotary engine, the Mazda RX-8 Hydrogen RE concept benefits from improved aerodynamics and optimized tires and weight-saving measures. A fast-fill tandem master cylinder reduces brake drag and friction hub carriers help cut power losses.



The vehicle also incorporates a host of other technologies for exceptional environmental compatibility. Three-layer, wet-on water-based paint on the RX-8 Hydrogen RE dramatically reduces the emission of organic solvents, saves energy by shortening the drying process and reduces carbon dioxide emissions. Moreover, the plant-based plastics used for the vehicle’s interior parts provide an attractive alternative to plastics derived from fossil fuels such as petroleum.



The Mazda RX-8 Hydrogen RE illustrates Mazda’s dedication to the future environment without abandoning true Zoom-Zoom and soul-of-a-sports-car thinking.
