A few things with your assessment: -the selling point of the Volt's driveline is reliability in the long term with minimal fancy electronics (relatively speaking). No mechanical interface between the electric motor and the ICE with the clutches and other crap that can break or go bad. The Volt's driveline is a reflection of what has worked for 100 years in submarines... seems to be a pretty solid foundation for a workaday car... -The battery is the motive force until voltage gets low, and a gas-powered generator rechrages it. How far you can go is still a matter of gasoline and mileage. Not sure if they've designed it to be plug-in rechargable, although they should. -Hub-in-wheel motors... nice in Car Wars, but in real life they add huge amounts of unsprung weight, expose the motors to shock and vibration (lowering service life), and your power cables have to be able to withstand literally millions of flexing actions over their lifetime. Not really an engineer's dream. How long will it take to work-harden the power cables so that you get a brittle fracture as you leave the driveway for work one winter's morning?
