Which Would You Rather? Chevy Volt or Nissan Leaf?��TheGMSource - The decision making officially begins today as we now know the cost of both the Chevrolet Volt and the Nissan Leaf. Chevrolet had previously announced an 8/yr - 100k mile warranty on the battery pack used to power the Volt for up to 40 miles of gasoline free driving. At the time of the Volts warranty announcement we didn\'t yet know what warranty the Nissan Leaf would have. Well, today not only do we know what the cost of the Nissan Leaf is, we also know the cost of the Chevrolet Volt. We also know what the battery will be for the Nissan Leaf and we want to know all things considered...which would you rather?
