Chevrolet's Volt hasn't even been released yet and other automakers are already hard at work developing their Volt killers. Sources at Autocar say that Mazda engineers have developed a working Mazda5-based electric vehicle prototype. The prototype is said to use a rotary engine to charge a battery pack that powers an electric motor driving the wheels.

Essentially, the only thing that's keeping Mazda from putting the system into production is the high cost of batteries. Meanwhile, Mazda is said to be concentrating on more conventional green tech, such as engine start-stop technology.
