We already know that Porsche is preparing a successor of the Cayman R, dubbed the Cayman GT4. What we didn’t know is that the upcoming Porsche Cayman GT4 will get the 3.8-liter twin-turbo boxer engine that will generate around 450 hp. This means that the Cayman GT4, will get the same engine that powers the 2014 Porsche 911 (991) Turbo.
As a result, the vehicle will also receive extra cooling vents, lightweight alloy wheels, centered exhaust pipes as well as a more efficient braking system. In addition, the Cayman GT4 will get a new rollcage in order to protect its passengers even better.
Regarding the design, we expect a new body kit but also a big rear wing. In the Porsche 911 (991) Turbo, the twin-turbo 3.8-liter six-cylinder engine delivers 520 hp and can push it from 0 to 100 km/h (62 mph) in 3.2 seconds, while top speed is limited at 318 km/h (197.5 mph).
The Porsche 911 (991) Turbo S uses the same engine, delivering 560 hp and can accelerate from 0 to 100 km/h (62 mph) in 3.1 seconds. Top speed is limited again at 318 km/h or 197.5 mph.
