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. Of course, being just a passenger means any evaluation is more or less just a guess. We should get to drive one of them sometime before the fully finished models go on sale next summer and then we will have a more definitive take on the car.

Keep the V8 – Dump the dog!

I know you're sad. But you have to go. You're killing the planet!
