The Mazda MX-30 EV with a rotary engine range extender is about to launch, so we're taking a look back at how Mazda has tried to make the rotary green.
In the RX-8, the powertrain was not that different from a regular automatic RX-8. In fact, at 207 horsepower running on gasoline, it was only down a few horsepower . The big difference was that four injectors, two for each rotor, were added in the tops of the rotor housings for running on hydrogen. The dual injectors were necessary to provide enough hydrogen for adequate power; emphasis on"adequate." Running on hydrogen reduced power to 108 horsepower.
Despite having both a gas tank and high-pressure tanks for hydrogen, the RX-8 still retained all four passenger seats. It did lose pretty much all its cargo space, though, to the hydrogen tanks. Range was rather short at just about 60 miles, though, likely a combination of hydrogen's low energy density and tanks that were restricted by the RX-8's relatively small package and having to save room for some gasoline.
The Premacy was initially shown with the same engine, but with the addition of a 40-horsepower electric motor to turn it into a hybrid. Along with the obvious efficiency benefits of running partially on electricity, the electric motor likely helped with off-the-line performance, since rotaries are notoriously lacking in torque. The Premacy had the whole powertrain mounted transversely and powering the front wheels like in a standard model.
