The Mazda Wankel engines (a type of rotary combustion engine, specifically a Wankel engine) comprise a family of car engines produced by Mazda, derived from experiments in the early 1960s by Felix Wankel, a German engineer. Over the years, displacement has been increased and turbocharging has been added.

Mazda rotary engines have a reputation for being relatively small and powerful at the expense of poor fuel efficiency. The engines became popular with kit car builders, hot rodders and in light aircraft because of their light weight, compact size, tuning potential stemming and inherently high power-to-weight ratio - as is true for all Wankel-type engines. Mazda put the engine into series production, with NSU (Ro80) and Citroën (GS Birotor), as part of the Comotor joint-venture, between 1967 and 1977.

Since the end of production of the Mazda RX-8 in 2012, the engine is produced only for single seater racing, with the one-make Star Mazda Championship being contested with a Wankel engine.

The 13B is the most widely produced engine. It was the basis for all future Mazda Wankel engines, and was produced for over 30 years. The 13B has no relation to the 13A. Instead, it is a lengthened version of the 12A, having 80 mm (3.1 in) thick rotors. It was a two-rotor design, with each chamber displacing 654 cc so two chambers (one per rotor) would displace 1308 cc; the series name reflects this value ("13" suggesting 1.3 litres), as with the 13A of the same displacement but different proportions.

I13B-REW

A twin-turbocharged version of the 13B, the 13B-REW, became famous for its high output and low weight.[citation needed] The twin Hitachi HT-12 turbos were operated sequentially, with only the primary providing boost until 4,500 rpm, and the secondary additionally coming online afterwards. Notably, this was the world's first volume-production sequential twin turbocharger system.[5] Output eventually reached, and may have exceeded,[citation needed] Japan's unofficial maximum of 280 DIN hp (206 kW) for the final revision used in the series 8 Mazda RX-7.

Applications:
-1992–1995 Mazda RX-7, 255 hp (190 kW)
-1996–1998 Mazda RX-7, 255 hp (190 kW)
-1999–2002 Mazda RX-7, 280 hp (210 kW)
