It would need to be a belt drive arrangement to an induction motor (in the 5 - 10 hp range) and using another VFD to create the appropriate output voltage.
How about having a gas engine that is on a direct drive to the drive shaft that is going to the rear axle? use a centrifugal clutch so that it spins free when the engine is not running and have it geared so the engine is running at it's max RPM when you are going 65mph or whatever you want your top speed to be, that way you extend your range while driving on the highway, you also keep it really simple and you don't have the losses from going mechanical to a generator to a speed controller to a motor to the wheels.
