The Renesis engine – also 13B-MSP (Multi-Side Port) – which first appeared in production in the 2004 model-year Mazda RX-8, is an evolution of the previous 13B. It was designed to reduce exhaust emission and improve fuel economy , which were two of the most recurrent drawbacks of Wankel rotary engines.
Although Mazda is well known for their Wankel "rotary" engines, the company has been manufacturing piston engines since the earliest years of the Toyo Kogyo company. Early on, they produced overhead camshaft, aluminum blocks, and an innovative block containing both the engine and transmission in one unit.

The Renesis in the Mazda RX-8 has the highest redline of a production wankel rotary-engine road car rated at 9000 rpm. In contrast, some older OHV (pushrod) engines had redlines as low as 4800 rpm, mostly due to the engines being designed and built for low-end power and economy during the late 1960s all the way to the early 1990s.
Following the 1990 season, Mazda continued development of the 787 chassis in order to make improvements on its pace and reliability. One major development was the intake system for the rotary engine. In the past, Mazda had developed variable-length telescopic intake runners to optimize engine power and torque for varying RPM levels.
