Top five Rotary Cars
1. Audi A1 e-tron concept.
This car is unique in the sense that its wheels are actually not driven by its rotary engine. An electronic motor producing 101bhp powers the Audi A1 e-tron. A single rotor engine extends the maximum range the 12kWh battery can provide.
The rotary unit only displaces 245cc and will only start up when the battery is low. This comes with a few benefits. Firstly, higher output per every liter of the rotary unit compared to a piston equivalent suggests that a lighter and smaller engine can be used. This improves the car’s power-to-weight ratio, and in turn, there is increased range and a boosted efficiency. Secondly, higher emissions and reduced fuel economy (which are the common issues often associated with rotary engines) are countered.
2. Mazda Eunos Cosmo
The 1990 Eunos Cosmo had a three-rotor engine and twin turbochargers. The 1962cc rotary unit produced up to 295bhp and 297lb ft of torque (even by today’s standards, this is a lot). The car could dispatch to 62mph in only 6.2 seconds. It was most powerful rotary car Mazda ever produce.
