"A 250 HP electric car is not only infeasible, but just as bad as a 250 HP gas guzzler."

I'm not so sure this true. There are several 200+ HP electrics now being offered for sale (delivery in the next year). The price is very high but battery technology that supports this discharge rate may become cheaper quickly. There is a big technical difference between IC engines and motors when you look at efficiency over a range of outputs. It's not hard to imagine an motor that can deliver a peak of 200 hp but is still very efficient at 10 hp. You can even build in multiple motors and just use the ones you need. I'm impressed by some of the "motor in wheel" concepts that have a motor built into each wheel. You get 4 WD when you need it and the ability to seamlessly go to front wheel drive, rear wheel drive or even one wheel drive when it's appropriate.
