This is the new Porsche Cayman GT4, a faster, more focused rendition of Porsche’s brilliant mid-engined coupe, developed by the firm’s Motorsport division.

Power comes from a reworked version of the 3.8-litre flat-six engine found in the 911 Carrera S, producing 380bhp and 310lb/ft of torque. There had been speculation that the GT4 would use a version of the turbocharged, 2.0-litre flat-four unit found in the 919 Hybrid race car. But Porsche’s engineers went down the old-school route, sticking as big an engine as possible in the thing.

A six-speed manual gearbox comes as standard – there’s no PDK dual-clutch option. 0-62mph takes 4.4 seconds, with a top speed of 183mph and Porsche claims a Nurburgring lap time of 7 minutes 40 seconds. Yet it still returns a respectable 27.4mpg and emits 238g/km of Co2.

Much of the Cayman GT4’s running gear is shared with big brother 911 GT3. If they had simply modified bits from the Cayman GTS, it wouldn’t have been the proper ‘GT’ car they wanted to create.

The front axle, front suspension, dampers, electric power steering (with bespoke software), and optional carbon ceramic brakes are all taken from the GT3. The rear suspension is all-new, just for the GT4.

The bodywork – including the huge, fixed rear wing – has been massaged for maximum aerodynamic effect. Up to 100kg of downforce is generated at high speed, as much as the GT3.

Inside, there are seats from the 918 hypercar and a model-specific steering wheel. Standard kit includes bi-xenon headlights, sports exhaust, Sport Chrono Pack with dynamic engine mounts, Porsche Torque Vectoring and a proper mechanical limited-slip diff. You can delete the satnav and aircon if you want, but why would you?

The Porsche Cayman GT4 is available to order today, priced from £64,451. Deliveries are expected to start in March. It makes its public debut at the Geneva Motor Show next month, as well.
