We found a very interesting comparison test between the Porsche 911 GT3 and the Porsche Cayman S.
The GT3 may be a classic in waiting, but so is the latest Cayman S. Its new 3.4-litre, direct-injection flat six now delivers 316bhp rather than its predecessor’s 261bhp, it rides on slightly wider tyres and the power steering map has been altered slightly.
It instantly scores over the 996 with a classier, tidier and quieter cabin, although road roar from the optional 19in tyres sometimes drowns out the radio. The Cayman is more surprising for its sheer get-up-and-go pace, which is mighty impressive for what, in the end, is a lower-order Porsche.
B-roads are the recommended habitat for the GT3 if you’re not slaying seconds on circuits. It will cruise motorways happily enough and has the pace to shrink them massively, but for demon thrills to get you addicted, find a swooping open road, spin the yowling six beyond 4500rpm and learn all about the magic of weapons-grade 911s.
