The RX-8 is available in two trim levels: GS and GT. Both models are equipped with the same engine. The GT model adds Dynamic Stability Control (DSC), xenon headlights, automatic headlight levelling, Bluetooth, satellite radio, moonroof, leather upholstery, and 8-way power-adjustable seats. The MSRP for the GS model is $37,295. The test vehicle is the GS trim with 6-speed manual transmission and optional R3 package, which includes performance parts such as a rear spoiler, integrated front bumper, Recaro seats, and 19-inch wheels. The MSRP for the R3 model is $40,780.
One of the most distinctive features of the RX-8 is undoubtedly its Wankel rotary engine. For four decades, Mazda has continued to champion the use of rotary engines in its high-end vehicles. The current design being used in the RX-8 was introduced in 2003 with the name “Renesis.” Unlike the common piston engines, rotary engines have fewer moving parts, and power is derived from the circular motion of rotors. The end result is a significantly lighter and smoother engine. However, rotary engines do have drawbacks: fuel efficiency and emission. Forty years of research and refinement by Mazda engineers have kept these shortcomings under control. The gas consumption is rated at 12.8L/100 km for city driving and 9.2L/100 km on the highway.
The RX-8 manual and automatic transmission models are equipped with different versions of the Renesis engine. The manual version produces a peak power of 238 bhp at 8500 rpm and a peak torque of 159 ft-lb at 5500 rpm. In the automatic version, the engine produces a peak 212 bhp at 8500 rpm and the same 159 ft-lb torque at 5500 rpm.
