Even with Ring's long straights the Elise is not outmatched by the boxter, it accelerates faster than the Boxter S:
Elise: 0 - 60 = 4.6 secs
Boxter S: 0 - 60 = 5.7
And factor in the Elise's better handling, I'd go Lotus. It would be interesting to see how it would match up against the new Cayman though.
