Finally the brand new Porsche 718 Cayman GT4 is here! Shortly before the new Toyota Supra or the imminent mid-engine Corvette, we can not think of any anticipated sports car, and endless speculation, tons of rumors, insane spy shots and nocturnal debates among our employees. The latest junior member of the Porsche GT family is the correct accents.
To get started, it packs a brand new 4.0 liter flat vacuum. At a time when only 10 percent of the 911 variants are naturally aspirated and 100 percent of the Cayman / Boxster models are turbocharged, the free-breathing Cayman GT4 (and its Boxster Spyder brother) stands alone. The great GT4 of the first generation drew its power from a 3.8-liter 385 hp naturally aspirated engine, which comes from the 991.1 Carrera S. So there is a precedent for this 4.0-liter model. The line of the powertrain is a bit confused this time, however, as Porsche claims it is a completely new engine, which is in no way related to the wild 4.0-liter engine of the 991.2 GT3 based on the 9A2 engine generation, the the soon to be replaced 991.2 Carreras drives. This is quite a jump over the regular 9A2, considering that all 991.2s from Base Carrera to Carrera GTS have the same 3.0-liter Twin-Turbo Flat-Six. With this new engine, at least the turbos and associated piping have been removed, cylinder capacity increased by one full liter, and new crankshaft, pistons, connecting rods, valvetrain, air intakes and cylinder heads installed. Against this background, it was supposedly too costly and complex to get the 4.0-liter GT3 to work here, which is hard to imagine. Regardless, this impressive design blade enables a speed of 8,000 rpm, which is higher than that of the 911 of the 992 generation.
Why the engineers in Flacht, where the racing cars and GT road vehicles are developed by Porsche, GT boss Andreas Preuninger holds fast to the natural claim and says he sticks to his guns. "We believe in [these] engines and hard work, there is always a way, and we will continue the path of natural aspiration for GT cars, the right way is not always the easy way." All right then.
A total of 414 hp and 309 lb-ft of torque are transmitted to the rear wheels via a six-speed manual transmission of the current 718 GTS. Porsche admits that there are plans for the future to bring the brisk PDK dual-clutch automatic transmission to the GT4, but you'll have to switch it yourself or look for another car for the time being. The performance is strong: the ride from zero to 60 mph takes only 4.2 seconds and the top speed is 188 mph.
