Hi,
Apparently the "real" numbers on the Volt are 40 miles on a full charge, and ~50mpg while in the charging.
ApteraForum.com - Aptera Car Forum - View Single Post - GM claims 230MPG for the Volt, is a 300MPG rating for the Aptera too conservative?
The 230mpg number comes from driving 51.1 miles and not counting the 40 miles of electricity that you used.
