Let’s do a little backtracking since I’ve already mentioned Mazda’s use of the RENSIS engine on two of their models – the RX-8 Hydrogen and their Mazda 5 Hydrogen Rotary Hybrid Concept Vehicle.

The RENESIS engine is a unique powerplant that Mazda originally wanted to put in its Mazda RX-EVOLV concept vehicle, the supposed to be next big thing in the world of sports cars. With the installation of the RENESIS engine, Mazda sees that it will be able to bring to realization its Mazda RX-EVOLV.

RENESIS means Rotary Engine GENESIS. It is a twin-rotor engine that could deliver a power output of 280 horsepower, which is the highest output ever to be achieved by a normally aspirated rotary engine, and its revs up to an amazing 10,000 revolutions per minute.

This RENESIS engine has been developed and improved from the multiple side-port experimental rotary engine which produced power for the RX-01 concept sports car that had been unveiled 12 years ago, at the 1995 Tokyo Motor Show.

Now, this conceptualized engine of 1995 is being used today to power some of the revolutionary vehicles of Mazda like its RX-8 hydrogen and the Mazda 5 hydrogen rotary engine hybrid concept.
