The electric motor is still moving the car. A smaller gasoline engine moves the generator, so it is not a Prius style hybrid.

If VIA is basing these trucks on the Volt, it's likely that there is in fact a mechanical linkage between the gasoline engine and the drivetrain. The original description of the Volt's configuration was less than accurate (while Lutz was still at GM, I believe).

The original description of the Volt's configuration was less than accurate (while Lutz was still at GM, I believe). A little bit of both was my understanding, so as to not waste the energy. I believe the main horse power still comes from the electric motor.
