The Porsche Cayman gets what is possibly the last major power-ballad-swansong before its turbo-charged replacement is due in 2016 so for the time being meet the naturally aspirated Cayman GT4. It shares many underlying components and philosophies with the 911 GT3 in that its a track car for everyday use. The mid-engined Cayman GT4 is powered by a 3.8-litre flat six, 385 hp engine and its only offered as a six-speed manual. Acceleration addicts will like the 4.4 seconds it takes to reach 0-62mph and welcome the 183 mph top speed that they will never reach. The Cayman GT4 is lowered by 30mm over the standard Cayman and aerodynamic tweaking, which includes that rear wing, not only generates lift but also decreases drag. Carbon ceramic brakes are optional but standard equipment highlights include bi-Xenon headlights, sports exhaust, Sport Chrono Pack with dynamic engine mounts, leather/Alcantara interior trim, sports seats, 20-inch alloy wheels. Porsche Torque Vectoring (PTV) with mechanical rear limited slip differential will ensure insane levels of grip and cornering. The Cayman GT4 is available to order now with first UK deliveries scheduled for summer, cost? £64k GBP.
