But the vehicle has a small gasoline-powered generator on board that can charge the battery on the fly when it gets low.

FORBES: Who Revived The Electric Car?

This configuration gives it all wheel drive and also allows the ECU to either send power to or retrieve power from (in the form of regeneration) either motor to recharge the on-board battery pack -- which can also be juiced up by plugging into the wall.
