I am here to crap in everyone's cheerios.
The Chevy Volt Gets 230 mpg? Only if you use bad math. : Good Math, Bad Math
To quote the author, "The honest way to describe it is to say "Up to 40 miles without consuming gas, and then 50 miles per gallon".
The Volt is a great idea, and so is all of the electric cars by
Coda,
Chrysler and
Nissan.
All we hear about is the Volt and Tesla though. There will be options.
