There's a reason Tesla bought one of the most advanced manufacturers of ultracapacitors. Li-Ion batteries are a "now" thing but they are looking past that. On the other hand, ultracapacitors will have their own complexities and issues.
0-60 is only a good measure of straight-line acceleration and using it as a metric of "goodness" presumes the car is also able to do other things that matter, like finishing the race without dropping into "limp home" mode. Fact of the matter is that Tesla can't finish the Nurburgring without falling into "limp home" mode. The battery flat-out overheats. Now, the fact of the matter is that I don't drive Nurburgring and very few people do. OTOH, it's a much closer analogy to real world driving than straight line quarter-mile segments.

I know engineers who are also Porsche fans that flat-out believe EVs are the future, even for sports cars. I respect them and I agree. I also agree that that future EV may not be a Tesla and that EVs still have some significant hurdles to overcome to be practical solutions for everyday driving for a (diminishing but still significant) population of people.
