From a styling perspective certainly, but it's a different matter entirely from behind the wheel.
As one of the best pound-for-pound sports cars money can buy, the Porsche Cayman S won't be too worried by the new mid-engined kid on the block. Alfa Romeo is only building a few thousand of the nimble, staggeringly beautiful 4C so it's not as if Stuttgart is too concerned by its Italian friend. Nevertheless these cars demand to be tested side by side, and Chris Harris is the man to do it.
Taking the cars to bumpy British roads levels the playing field somewhat. See which drives away the winner.
