It's expected to pack the same naturally aspirated 4.0-liter flat-six as the 911 GT3.
As we know, Porsche is preparing to unleash a new 718 Cayman GT4. We last saw a prototype of the 2019 model undergoing winter testing, and now the German sports car has been caught flexing its muscles at the Nurburgring without wearing any camouflage to hide its modesty. As we've come to expect from Porsche, these latest spy shots confirm the styling won't be a drastic departure from the outgoing model – but looks can be very deceiving.
For the 2019 Cayman GT4, the previous model's 3.8-liter engine will be replaced by a larger 4.0-liter flat-six naturally aspirated mill borrowed from the potent 911 GT3. Porsche's own Andreas Preuninger once said the company's GT cars will stay naturally-aspirated for one more generation, and he seems to be staying true to that promise. Of course, Porsche isn't going to let the cheaper Cayman GT4 invade the superior 911 GT3's territory, which is why the manufacturer is expected to detune the engine down to around 400 horsepower. This would give it a sufficient power advantage over the Boxster and Cayman GTS without treading on the toes of its bigger brother, the 500-hp 911 GT3.
The new Porsche Cayman GT4 is also expected to be offered with either a manual transmission or an optional PDK to satisfy both purists and lap-time chasers alike. A track-only Clubsport version is also expected to break cover in early 2019, but Porsche will most likely unveil the new road-going Cayman GT4 at the Paris Auto Show before then in October, so be sure to have your checkbook ready.
