Porsche Cayman GT4 review - the ultimate drivers' Porsche? - Engine and gearbox
The Cayman we've all been waiting for
The Cayman GT4 borrows the 911 Carrera S’s 3.8-litre Powerkit engine, which gives the car plenty of straight-line performance. Low-down torque is strong and with the redline set at 7800rpm it has good top-end reach, too. Being a highly-tuned, normally-aspirated engine throttle response is razor sharp, which means you can precisely manipulate the rear axle under power. The six-speed manual gearbox is one of the best around. The shift action is so sweet you change gears just for the tactile joy of it. It’s just a shame that the standard car’s overlong gear ratios remains. The extra torque of the 3.8 does disguise the problem to some degree, but with shorter ratios the engine would feel punchier still and you could enjoy the gearshift more often. As it is, the combination of low-down torque and top-end reach of the engine combined with the long gearing mean you can actually leave it in third gear most of the time. It’s like that moment with Nintendo Wii when you realise a casual wrist-flick is just as effective as a lunge across the room.
