FYI, for those claiming the credit this year, just wanted to let you know that you need to select the "Alternative Motor Vehicle" even though those imply NG or Fuel Cell vehicles. Took me a while to figure that out, switching to "forms" view did the trick - when you select that, even though it's not those kinds, it uses IRS Form 8910 which is the one you want, the rest is self-explanatory.
Enjoy!
