From what I've read about the Volt so far it seems it wont stand a chance against the Prius. $40 grand US versus $20 grand for a start. 2ndly, thenuisance of plug-in daily charge versus none at all for the Prius. 3rdly, the rather silly idea of carrying a 1 litre engine purely to use as a generator rather than as a secondary method of propulsion. I think it's a matter of too little, too late for GM. Toyota will be on their way to a 4th gen Prius by the time the Volt is available.
