First Vision of the Porsche Cayman GT4: 414 hp, Hard Hardware – MotorTrend



Finally, the new Porsche 718 Cayman GT4 is here! Without the new Toyota Supra or upcoming mid-range Corvette, we can not imagine the more anticipated sports cars lately and after endless speculation, tons of rumors, foolish spy pictures and nighttime debates among our employees, the newest junior member of the family the Porsche GT removes all the right boxes.

For starters, it contains a completely new 4.0-liter naturally aspirated flat six. That's right, in an era where only 10% of the 911 variants are naturally aspirated and 100% of the Cayman / Boxster is a turbocharger, the free breathing Cayman GT4 (and his brother Boxster Spyder) is alone. The top-of-the-line GT4 developed 3.8-liter, 385 hp. naturally aspirated six, coming from the 991.1 Carrera S, so there is a precedent for this 4.0-liter model. The propulsion line is a bit more confused this time as Porsche claims it's a brand-new engine and is not at all connected to the wild 4.0-liter at 991.2 GT3.

Porsche tells us that this new engine is based on the 9A2 generation of engines that power the soon-to-replace 991.2 Carreras. This is a big leap from the regular 9A2, but considering that all 991.2s of Carrera through the Carrera GTS are the same 3.0-liter twin-turbo flat-six. At least this new engine has removed the turbo and service plumbing, and its flow has been increased by a full liter and has been filled with a new crankshaft, pistons, connecting rods, gas distributors, air inlets and cylinder heads. Against this work, it is said to be too expensive and complicated to achieve 4.0-liter GT3 work here, which is hard to imagine. Nevertheless, this impressive sheet of construction allows for a red line with 8,000 rpm, higher than that of the 992-generation 911.

As to why engineers in Flacht, where Porsche racing cars and GT cars have been developed, touched by natural drive, GT boss Andreas Preuninger says he sticks to his weapons. "We believe in the engines [these] and in the hard work, there is always a way and we will continue naturally for GT cars." The right way is not always the easiest way.

A total of 414 horsepower and 309 pounds of torque are dispatched to the rear wheels through a six-speed manual gearbox coming from the current 718 GTS. Porsche admits that in the future, it plans to import the GT4 fast-coupled PDK dual-action automatic transmission, but for now you have to move it yourself or find another car. Performance is strong, with a take-off from zero to 60 km / h takes just 4.2 seconds and a maximum speed of 188 mph
