The first version of the Mazda RX-8

The first version of the RX-8, chassis code SE3P, was produced from model year 2003. It is powered by the RENESIS 13B-REW (multi side port) Wankel rotary engine displacing 1.3 litres non-turbo (1308 cc). At launch, the RENESIS was available in standard and high power versions. The 6-port standard RENESIS produced 210 hp (160 kW) and was coupled with either a 5-speed manual or 4-speed automatic transmission. The 6-port high power RENESIS was only available with a six-speed manual transmission and was rated at 250 hp (190 kW). For the North American market, Mazda revised the reported output rating of the standard and high power RENESIS soon after launch to 197 hp (147 kW) and 238 hp (177 kW), respectively.[2] With exhaust ports now located in the side housing, the RENESIS boasted improved fuel efficiency and emissions rating over the 13B-REW employed by the last RX-7, thereby making it possible to be sold in North America.
