2010 MAZDA RX-8: PURE SPORTS CAR VERVE MEETS FOUR-DOOR FUNCTIONALITY
Launched in 2003, the Mazda RX-8 hit the global market wîth a serious bang. The RX-8 has won 48 global vehicle awards since its release including 2003 Japanese Car of the Year, Australia's Wheels magazine's Car of the Year for 2003, 2003 International Engine of the Year, 2004 Singapore Car of the Year, the 2004 Ú.S. Best Sports Car and ÚK Car of the Year 2004. It was also named on Car and Driver magazine's Ten Best list for 2004, 2005, and 2006. In addition, the RENESIS Rotary Engine has won nine awards since 2003. All together, Mazda has sold nearly 182,000 RX-8s around the world.
Significantly updated for 2009 wîth a refreshed exterior and interior design, enhanced performance and an R3 model for the ultimate driving enthusiast, RX-8 maintains the same great features for 2010, while refining a few simple touches. To better accommodate consumer demands, the 2010 RX-8 is available wîth two trim levels - Sport and Grand Touring - and the R3 model, specially designed wîth the enthusiast in mind. Únchanged 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.
'Since the launch of the Cosmo Sport in 1967, every sports car ever developed by Mazda has had the same fundamental mission - to provide vehicle lovers wîth an affordable, fun-to-drive alternative,' said Chris Hill, RX-8 vehicle line manager. 'The 2010 RX-8 embodies that mission, conveying the unique and distinctive Mazda brand DNA to the fullest.'PERFORMANCE INNOVATION - MORE SPORTS CAR DRIVING PLEASÚRE
Through-and-through, the RX-8 is a pure sports car that gives the driver an exciting and dynamic experience. With its superior body rigidity and structural reinforcements, the rear suspension geometry was reconfigured for the 2009 model year for better handling performance and improved driveshaft rigidity.
To achieve this sophisticated dynamic, Mazda utilizes the advanced RENESIS (Rotary Engine genesis - or rebirth of the rotary engine) engine. The Mazda RX-8 remains the only mass-produced rotary-powered passenger car in the world. While exhibiting unusually high power output for a naturally aspirated engine, RENESIS outstrips comparable reciprocating engines in terms of acceleration, the feeling of power in reserve and quick response.
The Mazda RX-8 is available as either a 232-horsepower model fitted wîth a six-speed manual transmission, or a 212-horsepower model fitted wîth a six-speed automatic wîth §teering-wheel-mounted paddle shifters for a Formula 1-style driving experience.
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 wîth 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 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 wîth large-diameter internal pistons and valving, which offer excellent road feedback and a smooth ride.
An electric rack-and-pinion power-§teering 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 §teering assistance rather than a conventional power-§teering pump. The electric motor provides additional assistance at low speeds to ease parking and reduces §teering assistance at higher speeds to provide greater road feel, responsiveness and feedback. And, in keeping wîth the rest of the development on RX-8, it is far lighter and easier to package than a conventional power-§teering rack.
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 §teering and suspension systems. Dynamic Stability Control wîth TCS (standard on Grand Touring and R3) delivers a superior level of handling that can be disabled when driving and road conditions allow safe operation.Source - Mazda
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 fixed 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 wîth three-point seatbelts. Even pedestrian protection was considered, as the RX-8 is fitted wîth 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.
DESIGN CÚES PROVIDE 'HIGH-QÚALITY' DYNAMISM
RX-8 was designed wîth an athletically sculpted exterior that provides a sense of originality that's unrivaled in the marketplace today. Carrying over design enhancements from the 2009 model year, the 2010 RX-8 features a high-class look without impairing the basic design thémé. Key design elements include aggressive front and rear bumpers and front fascia, sporty, high quality finish front headlights and rear LED taillights and larger exhaust pipes. The RX-8 also offers a new 10-spoke wheel design featuring a symbolic and sporty design in the motif of a rotary engine wîth different arrangements for each wheel size.
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.
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 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.
The RX-8's exterior styling presents a genuine sports car form, while the interior boasts a comfortable and intelligently designed cabin. A simple, yet functional, interior design supports driving pleasure. Interior highlights include an athletic §teering wheel, front and rear sports seats, an ergonomic center IP and an LCD touch-screen navigation system.
A variable red zone was also added to the tachometer. An extremely low cabin floor allows the seats to be mounted low in the chassis, which, along wîth 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.
PACKAGING INNOVATIONS - ÚLTIMATE PERFORMANCE R3 MODEL
To cater to the driving enthusiast, the RX-8 offers an R3 model. Providing the very best in rotary-powered motoring, the R3 model adds a sport-tuned suspension wîth Bilstein shock absorbers and front suspension crossmembers filled wîth urethane foam for better ride comfort. Rear spoiler, side sills, fog lights, Xenon headlights and sporty front bumper are added to enhance the sporty appearance along wîth 19-inch forged aluminum-alloy wheels wîth high performance tires.

Operations in Canada are managed by Mazda Canada, Inc., located in Ontario, Canada, and in Mexico by Mazda Motor de Mexico in Mexico City.
The only coupe with a four-door configuration, the Mazda RX8 was built for driving enthusiasts. Featuring a high-revving 1.3-liter rotary engine that was called the Renesis, the engine was quite impressive. The exhaust ports were located on the side of each of the combustion chambers, instead of on the outer edge of the rotary housing. This engine allows for more power, lower emissions and higher fuel economy.
The engine was able to be mounted further back in the RX-8's chassis because of the engine's compact size, giving the vehicle the coveted 50/50 front/rear weight distribution. At a very svelte 3,000 lb curb weight, the RX8 featured balanced suspension tuning and sharp steering. The Mazda RX-8 was one of the best-handling vehicles on the market, and was among the best sports cars available for less than $30,000.
After nearly a decade of lack, introduced in 2004, the Mazda RX-8 brought back the rotary-powered sports vehicle to the U.S. Mazda also received an image with greater stature and performance than the Miata. Usually Mazda sells its sport coupe with either manual or automatic transmission, though most enthusiasts would agree that the six-speed manual version is the best way to experience the RX-8.
The manual-equipped Mazda RX-8 featured horsepower that crested at 238 at 8,500 rpm with redline hitting at an impressive 9,000. The RX-8 was timed at .6 seconds to 60 mph and 15.1 seconds through the quarter-mile, as tested by Inside Line testers. Automatic RX-8s redlined at 7,500 rpm.
Comfortable enough for a daily commuter, the Mazda RX-8 isn't the most economical choice as the fuel economy tends to hover in the high teens. The interior of the car was quite nice as well. The reverse-hinged rear doors allowed for the loading of cumbersome child seats, while the rear seats are roomy enough to accommodate adults on short trips.
Manual version came with a firmer suspension and 18-inch wheel, while these were optional on automatic models. Through the Shinka Special-Edition package, further suspension upgrades were available, along with luxuries such as leather upholstery and a navigation system.
A descendent of the two-door RX-7 sport coupe that was sold in three generations from 1979 through 1995, the Mazda RX-8 featured an extra set of doors. Unfortunately the RX-7 was taken off the U.S. market due to poor sales and difficulty in reaching emission standards. However, the RX-7 continued to be sold in Japan through 2002. At the time it was deleted, the third generation RX-7 was sold for $32,500 in 1995, a much more expensive vehicle than today's RX-8.
The 2004 RX-8 is almost a return to the original RX-7, while still being a completely different sort of sports car. With a newly redesigned rotary engine, the RX-8 featured reverse-opening doors and room for four adults, making it quite an impressive vehicle. The new RX-8 also featured the newly designed, naturally aspirated 'Renesis' version of the good, old 13B rotary. The rotary engine had no valvetrain, and the location of these parts is crucial to the engine's performance. In the earlier engine, these ports were located on the outer edge of the rotary housing, while in the Genesis they are on the side of the rotary chamber. This location allows engineers to completely close the exhaust port before the intake port opens, and vice versa, unlike the earlier design. Along with a variable intake system that optimizes air flow, the new Genesis also allows them to use 30-percent larger intake ports than before. The redline was now up at an amazing 9,000 rpm.
Even more impressive was that even with access to the rearward accommodations the four-seater still retained a sports car-s balance thanks to 50/50 weight distribution and a supple chassis with double-wishbones up front and a multilink independent system in the rear. The Renesis engine sat back in its chassis much like the 12A did in the original RX-7. Part of the package is the naturally, four-wheel disc brakes with ABS and rack and pinion steering. The Mazda RX-8 weighs in at a very impressive 3,029 lbs in manual transmission form.
The RX-8's main source of competition lies in the new Nissan 350Z, basically because Mazda's own people were quoting curb weight comparisons.
Edmunds.com chose the RX-8 as the winner when pitted against the 350Z as it generated 238 horsepower from a measly 1.3 liters. The RX-8 yielded 6.6 seconds in the 0-60 mph track test. The RX-8 glides through bends and turns in a manner that's far less intimidating the Z, which hammers it ways through bends, according to Edmunds.com.By Jessica Donaldson
