The Ariel Atom 500 (with the V8) is a little bit faster at 2.3 seconds 0-60. However it's not really a daily driver kind of car like the Tesla: https://www.youtube.com/watch?v=SIiWhWpzFQQ
The Tesla is a 4-door sedan that you could easily use to pick up business partners from the airport. You might as well compare the tesla to a BMW HP4 (superbike).
