Porsche 718 Cayman GTS Spotted With Possible Six-Cylinder Engine

Porsche introduced the 718 Boxster and Cayman GTS over two years ago and it appears the company is working on upgraded models with a new six-cylinder engine.

Recently caught undergoing cold weather testing, this prototype looks like a fairly typical 718 Cayman GTS. However, the rear end closely echoes the one used on the 718 Cayman GT4. That being said, it eschews the fixed rear wing and has a less extreme diffuser.

While nothing is official, our spy photographers believe this is an updated Cayman GTS which will use the same 4.0-liter six-cylinder engine as the Cayman GT4. In the latter model, the mill develops 414 hp (309 kW / 420 PS) and 310 lb-ft (420 Nm) of torque.

To keep the model hierarchy intact, the engine will be detuned for use in the GTS. The exact numbers remain mystery, but sources have suggested the car will have 395 hp (294 kW / 400 PS) and 310 lb-ft (420 Nm) of torque. If that’s correct, the six-cylinder GTS would have 35 hp (26 kW / 35 PS) more than its four-cylinder predecessor and 20 hp (15 kW / 20 PS) less than the GT4.

Like the current GTS, the model is slated to be offered manual and PDK transmissions. With the latter gearbox, the new car should beat the current GTS’ 0-62 mph (0-100 km/h) time of 4.1 seconds when equipped with the Sport Chrono Package. However, it remains unclear if the top speed would increase from its current rating of 180 mph (290 km/h).

Interestingly, there’s the possibility that Porsche could keep the current GTS around even after the new model is introduced. If that happens, the high-performance variant could be known as the GTS 4.0. Of course, that’s just speculation and the company’s plans could vary by market.
