The Mazda RX-8 is a sports car manufactured by Mazda Motor Corporation. It first appeared in 2001 at the North American International Auto Show. It is the successor to the RX-7 and like its predecessors in the RX range it is powered by a Renesis rotary engine. The RX-8 began North American sales as 2004 model year car.
The RX-8 was designed as a front mid-mounted, rear-wheel drive 2+2 coupé. The car has a near 50:50 weight distribution, achieved by mounting the engine behind the front axle and the gas tank ahead of the rear axle. Weight is trimmed through the use of materials such as aluminium (hood & rear doors), and a carbon fiber composite driveshaft on the manual gearbox car; designed to reduce rotational mass connected to the engine. The rest of the body is steel, save for the plastic front and rear bumpers.
The car features a pair of rear-hinged "freestyle" doors (similar to suicide doors) in order to provide easier access to the rear seats. The RX-8 has no B-pillar between the front and rear doors, with the leading edge of the rear door acting as a 'virtual pillar' to maintain structural rigidity. Because of the overlapping design, the rear doors can only be opened when the front doors are open.
Mazda introduced a special Shinka edition to the U.S. market in 2005, and to the UK market in 2006 where it was branded as the Evolve. Unique features include Shinka badges on the B-pillars, re-styled mirrors, alcantara-trimmed leather seats on the 2006 MY, stiffer chassis and suspension tuning, and polished wheels. For the 2005 MY, the Shinka was only available in Black Cherry Mica, and in 2006, it was available in Copper Red as well as some of the standard model colors. Power output remains unchanged from the standard models. This model is also offered in Japan as the Sports Prestige Limited RX-8. The Shinka option is not available for 2007. Mazda Japan is working on a Mazdaspeed version of the RX-8 dubbed the Mazdaspeed M'z Tune and will be released as a 2007 model.
