We had a Tesla arrive at our autox yesterday. The owner was quite happy to show off the car and explain its features. Naturally I parked my Elise next to it -- you can see the shared DNA, but overall the Tesla is much bigger and not as "sculpted" (at least in my eye).
He was new to the sport, so his times were difficult to benchmark. My instructor commented that the torque was unbelievable, but overall he felt the car to be a bit of a "boat" compared to the Elise (d'uh -- a Tesla is almost 3000 pounds). It was eerie to see it run but not to hear anything.
Anyway, the owner had a blast, and he was quite surprised at how little "charge" he used. I suspect that if he returns he will continue to improve -- there's a lot of potential for him to take advantage of. His "mileage" will certainly decline as he gets a sense of how to use all of the massive torque.
If only my Elise had that much twist
