C111 test models would use diesel engines and the rotary largely faded from the mainstream. Hidden in the back seat of many 1994–2005 Volkswagens and Audis sits a tiny Wankel rotary engine whose sole duty is not to turn fuel into horsepower and braps but to save the life of a person. The story of how Penske's Ilmor-Mercedes engine for the 1994 Indy 500 went … At one stage the 'Wankel' rotary engine could have been applied to multiple cars and even military vehicles.

In a piston engine, the same volume of space (the cylinder) alternately does four different jobs -- intake, compression, combustion and exhaust. Instead of raw performance, the Familia Rotary cars skirted Japan’s annual road tax by having a displacement under 1.0-liter, but maintaining the power expected out of a traditional four-cylinder engine of significantly larger size. Over its life the RX7 performed well in races such as 24 hours of Daytona and the British Touring Car Championship. When VW/Audi introduced the B5 platform in 1994, the all-new chassis showcased the German automakers’ engineering prowess in the mid-’90s. The Indy 500 engine they had to outlaw Undefeated and never to be repeated. The wrinkles in the Rotary dream would eventually be ironed out – but by 1973 the oil crisis and ongoing tooling problems meant that, there wasn’t the political or economic will to press on with the new engine. You know, the tiny powerplant that use less moving parts than a conventional piston engine, but creates huge amounts of power per litre. The second Mazda to feature a rotary engine was the 1968 Mazda Familia Rotary Coupe and Sedan (known outside of Japan as the R100). At least within Mercedes-Benz. A new configuration of a rotary engine – the Szorenyi rotary engine – has been developed by the Melbourne-based Rotary Engine Development Agency (REDA).

Power came from a 1.3-liter four-port 13B rotary, the most popular Mazda Wankel engine built and in production for over 30 years. While the stator, or stationary part of the Szorenyi engine is similar to that of a Wankel engine, the geometric shape of the engine rotor is a rhombus, which deforms as it rotates inside the contour of the stator.

The only thing wrong with Mazda RX 8's sold in the USA is that Mazda requires the use of very thin light weight 5W-20 oil that breaks down and cannot protect the rotary engine and catalytic converter from early failure, because the normally very hot running engine runs very, very hot especially in slow traffic and long drives in warm weather. Ford, GM, and Mercedes-Benz were in SkyActiv-R – also known as New Generation Rotary Engine – is the name of the powerplant hiding under the long, sculpted hood of the RX …
