"Plug it in to any outlet overnight and it will go 40 miles without a drop of fuel, 650 miles on a single fill-up. At least that was the promise when the Volt concept was unveiled."
I though I saw a nissan commercial claiming that the new Altima could already do 600 miles on a single fill up- maybe HYW. But the concept of not using a drop of gas for up to 40 miles sounds real good! I hope they can pull it off...
