The Porsche Cayman GT4 has every chance of outperforming the 911 Carrera and even the Carrera S, and it will be on tracks like the Nurburgring that such feats will be realized. Spied in its home country for the second time in as many months, the high-performance variant of the mid-engined sports car has a lower ride height, new aero kit, larger brakes housed in bigger lightweight wheels, a rear ducktail spoiler and a massive rear wing. It should have around 400 hp, which will be sent to the wheels via a seven-speed dual-clutch.
