According to
this link the EPA MPG is going to be 65mpg. Not likely, but heck, at the price point (sub-$15k) they're likely to sell all they can produce if it's even close to 50mpg.
Interesting... Between this, the new Festiva, the 2011 Focus, and the CR-Z, the next few years promise to be exciting times to be in the market for a new high MPG car. Lots of options that weren't even on the radar just three years ago.
