A few years ago, not many people would have guessed that Porsche->ke1 would introduce a GT, high-performance model with a manual transmission. I say this because even cars like the 911 GT3 and 911 GT3 RS are only available with a seven-speed, PDK, dual-clutch gearbox nowadays. But the 2016 Cayman GT4 is not only the most powerful production Cayman, but it's only available with a six-speed, manual transmission and a mechanical limited-slip differential.

Chris Harris was lucky enough to get behind the driver's seat of the Cayman GT4 on the Portimao circuit, and his video->ke278 reveals exactly what you'd expect: the latest Porsche sports car->ke506 is pure, unadulterated fun on wheels. The biggest difference compared to the next-best thing in the Cayman range, the GTS, is a new suspension. The front suspension has been taken straight out of the GT3 and modified to fit on the smaller Cayman, and the rear is exclusive to the GT4.

Developed specifically to be let loose on a circuit, the GT4 Cayman is equipped with a 3.8-liter, flat-six engine that delivers 385 horsepower and 310 pound-feet of torque. These numbers translate into a 0 to 62 mph acceleration of 4.4 seconds, and a top speed of 183. Unfortunately, of the 2,500 units or so that are to be manufactured, almost all have been spoken for.
