Mazda RX-8
The Mazda RX-8 is a sports car manufactured by Japanese automobile manufacturer Mazda between 2003 and 2012. It was first shown in 2001 at the North American International Auto Show. It is the direct successor to the RX-7. Like its predecessors in the RX range, it is powered by a rotary Wankel engine. The RX-8 was available for the 2003 model year in most parts of the world.
The Mazda RX-8 utilizes a rotary Wankel engine, and the non-reciprocating piston engine uses a triangular rotor inside a near oval housing, producing from 141 kW (189 hp) and 164 lb⋅ft (222 N⋅m) of torque, to 177 kW (237 hp) and 159 lb⋅ft (216 N⋅m) of torque from launch.
The RX-8 was discontinued for the 2012 model year without a successor. It was removed earlier from the European market in 2010 after the car failed to meet emissions standards. Due to falling sales from Europe coupled with rising yen prices, Mazda could not justify the continued sale of the RX-8 in other markets. 192,094 units were produced during its nine-year production run.
Mazda introduced rotary-powered vehicles in the US in 1971, beginning with the R100 and eventually introduced the RX-2, RX-3, RX-4, RX-5, and three generations of the RX-7 sports car in the US and worldwide markets. However, due to the lack of conveniences and user-friendliness, coupled with the high price tag and declining interest in sports cars and coupés at the time, Mazda decided to withdraw the RX-7 from most major markets except Japan. After 1995, Mazda suffered from a relatively undistinguished and ordinary product line in the US except for the MX-5 Miata.
As popular interest in import tuning and performance cars resurged in the late-1990s, due in part to various popular cultural influences, Japanese automakers waded back into the performance and sports car market in the US and in worldwide markets. Endeavoring to rejuvenate itself around this time, partially with financial and management assistance from its new owner Ford, Mazda developed a new line of high-quality cars with desirable styling and driving dynamics superior to competitors, beginning with the Mazda6 and followed by the Mazda3. This paved the way for the arrival of Mazda's next-generation rotary powered sports car.
The RX-8 combined two previous products (the internationally sold RX-7, and the Cosmo which was exclusive to Japan), with the exterior dimensions of the RX-8 to be slightly smaller than those of the Cosmo. Mazda chose not to install the 2.0 L three-rotor 20B-REW, which was discontinued in 1996 when the Cosmo ceased production.
The development of the RX-8 can be traced as far back as the 1995 RX-01 concept car, which featured an early iteration of the 13B-MSP engine. Naturally aspirated with side exhaust ports, this engine has a power output of 210 hp (157 kW).[citation needed] Because of Mazda's financial position at the time and the growing market interest in SUVs, the RX-01 did not see further development or production. However, a "skunkworks project" engineering team within Mazda kept the development of the 13B-MSP alive using an elongated MX-5 chassis known internally as "gokiburi-ka", or "cockroach car" translated to English, eventually catching the attention of management, which was by then heavily influenced by Ford. Development of the 13B-MSP advanced and eventually led to the RENESIS name debuting along with the RX-EVOLV concept car which began to bear semblance to the production version of the RX-8 with the "freestyle" rear suicide doors. The styling was further refined, in Mazda tradition, by competition between its design studios in Japan, the US, and Europe. The lead designer was Ikuo Maeda, the son of Matasaburo Maeda (the lead designer of the original RX-7). The project obtained official approval from management under one condition, that the resulting car should have four doors, and eventually the RX-8 concept car (design/engineering model) was produced and shown in 2001, closer resembling the production version. A near-production "reference exhibit" RX-8 was shown shortly thereafter at the 2001 Tokyo Motor Show, pending final approval for production. The production version of the RX-8 closely resembles this vehicle save for minor trim details, and "Job 1" began in February, 2003 at Mazda's Hiroshima plant in Japan.
The RX-8 was designed as a front mid-engine, rear-wheel-drive, four-door, four-seater quad coupé. The car has a near 50:50 front-rear weight distribution and a low polar moment of inertia, achieved by mounting the engine behind the front axle and by placing the fuel tank ahead of the rear axle. The front suspension uses double wishbones and the rear suspension is multi-link. Weight is trimmed through the use of materials such as aluminum and plastic for several body panels. The rest of the body is made of steel, except for the plastic front and rear bumpers. The manual gearbox model uses a carbon fiber composite driveshaft to reduce the rotational mass (momentum of inertia) connected to the engine. Power is sent to the rear wheels through a torque-sensing conical limited-slip differential for improved handling. While underpowered in comparison to the final variant of the RX-7,[citation needed] the RX-8 is considered its successor as Mazda's rotary engine sports car. [citation needed]
