Ingenious Mazda looks like a winner

The RX-30 is a good example of that adapability and ingenuity. A plug-in hybrid vehicle in reverse, if you like. Unlike traditional PHEVs the wheels are driven exclusively by a 17.8 kWh battery with a rotary engine acting as a generator, so the car is always being powered by electricity. The rotary engine found fame in the firm's RX-7 and RX-8.
