I hope the chevy Volt will be a success because it is more of a Hybrid than the prius anyways, A pious uses a heavy transmission and gearbox for the gas motor, as the gas motor is linked directly to the wheels, wheres the Volt only uses the motor to re-charge the battery/run the electric motor, kinda like a diesel locomotive, except it has a battery pack and can be plugged in to the wall at home. Can't do that with a Prius without an un supported un warrantied upgrade. Couple it all with a navigation system which is becoming a standard along with a 40 some mile range and the car becomes great little commuter car, and it also has the gas motor to fall back on with incase you need extra range due to unexpected trips. Also the gas motor on the Volt runs a constant rpm to power the generator which makes the generator more simple and the engine can be optimized for that RPM for economy, something you can't do with a direct drive Prius. With a Navigation system you can help keep the gas engine from running as often as well.
Consider this, you live 18miles from work, so you drive 36 miles to and from work. You put your route on the navigation system and you plug your car in at night. The gas engine normally kicks in when your charge reaches 20% on your battery pack. This is a "soft limit". When you reach 5% the GAS engine kicks on unconditionally. Battery pack has a 40 mile range on it.
Get in car to go to work, on the way to work your car notices you are going to work and makes a note of it. On your way home it notices you are driving home. 4 miles from home it would normally kick in the gas engine because your battery is at 20%, but instead your nav system politely asks you if you are going home, you press the big green touchscreen YES button and the care remains running on battery till you reach home and are able to plug it in. You reach home and your car has a 10% charge on it and you plug it in. The next morning you are at 100% and you have used no GAS for the previous day's commute.
Say the next day you need to make a detour on your way home and you drive a different route then your car will notice this by it's navigation system and will turn t6he gas motor on at 20% to ensure you have pleanty of juice to get home on.
Oh and the Volt uses modular components, so a gas and diesel volt or stiring engine volt will use the same electrical parts as well.
I just home GM don't kill it with mismanagement like they did the EV-1.
