First glance at the Porsche Cayman GT4 2020: 414 hp, hard core material – MotorTrend

Finally, the all-new Porsche Cayman GT4 718 has arrived! Apart from the new Toyota Supra or the future mid-engined Corvette, we can not think of a more awaited sports car from the end of the years, and after endless speculation, tons of rumors, photos from the world over, and more. The most recent junior member of the Porsche GT family meets all the criteria.

For starters, it contains an all-new naturally aspirated 4.0-liter flat-six. That's right, at the time when only 10% of the 911 variants are naturally aspirated and 100% of the Cayman / Boxster range is turbocharged, the Cayman GT4 (and its brother Boxster Spyder) free breathing stands out. The sublime GT4 first generation drew its energy from naturally aspirated six-cylinder 3.8 liter and 385 horsepower from the 991.1 Carrera S. There is therefore a precedent for this model of 4.0 liters. The powertrain lineage is a little more confusing this time, however, as Porsche claims, this is a brand new engine that has nothing to do with the wild 4.0 liters of the 991.2 GT3.

Porsche tells us that this new engine is based on the generation of 9A2 engines that propels the 991.2 Carreras, which will soon be replaced. However, this is a leap forward from the conventional 9A2, all 991.2 Carrera-based Carrera GTS offering the same six-cylinder 3.0-liter flat twin turbo. At a minimum, the turbos and auxiliary plumbing were removed from this new engine, its displacement was expanded by one liter and filled with new crankshaft, pistons, connecting rods, connecting rods, valves, aspirations and cylinder heads . Against this work, it would have been too expensive and complex to do here the work of 4.0 liters of the GT3, which is hard to imagine. Whatever the case may be, this impressive construction sheet allows for an 8,000 rpm redline, which is superior to the 992 generation 911s.

As for the reason why the Flacht engineers, where the GT racing cars and road cars are developed, remained stuck in a natural aspiration, the boss of the GT, Andreas Preuninger, said that it remained true to his position. "We believe in [these] engines and in hard work. There is always a way and we will continue on the naturally aspirated track for GT cars. The right way is not always the easiest. "Very well then.

A total of 414 horsepower and 309 lb-ft of torque is sent to the rear wheels through a six-speed manual transmission derived from the current 718 GTS. Porsche admits that it has plans to bring the GT4 to the PDK dual-clutch automatic, but for now, you'll have to change it yourself or find another car. The performance is strong, with a race from zero to 60 mph taking just 4.2 seconds and a top speed of 188 mph.
