Tesla has room to grow with the Model S sedan, Calif. factory

We got a brief ride in a prototype of the Tesla Model S all-electric sedan, and as far as we could tell from the passenger seat, it seemed like a luxury performance bargain for just $57,400.

Porsche has announced ratings for the 2010 sedan; it will get a combined figure of 18 mpg or 19 mpg from the EPA, depending on the model.
