Final Verdict
Launched as a 2015 model at the Geneva Motor Show, the Cayman GT4 was limited to about 2,500 units and with a starting with the base price of $85,595 in the U.S, it is immediately clear that this is not a normal Cayman model variant.
The spec sheet is a lovely list of the best performance bits from the Porsche Motorsport division. It takes its suspension from the GT3 and steals the Carrera S 3.8-litre engine along with a sweet 6 speed manual transmission. Great start.
Power comes in at 380 bhp @ 7400 rpm, with torque of 309 lb-ft. As expected, the benchmark 0-60mph sprint passes in ~4.2 seconds on its way to a top speed of 183mph. While this isn’t that fast on the spec sheet, in the real world it is plenty fast enough and with a 7:42.00 Nurburgring lap time it is clear that the sum of all the parts makes one hell of a machine both on street and track.
