It was only the 2.7 mate, the Boxster S has a 3.2, and that would be a very close thing, i drove one before i got my Zed and if anything the Boxster felt like it would be quicker round a track. i have a sneaking suspicion they deliberately chose the 2.7 because the 3.2 might have won, lol.

+1, the 3.2 s is faster in the straights and round corners. The boxster wins as its mid engine and is much much lighter than the Z.
