Last month, Porsche introduced the 2018 718 Cayman and Boxter GTS, both of which currently sit as the models range toppers. However, the German marque has yet to reveal an all-new Cayman GT4. Now, it seems as though the high-performance GT4 could soon be entering production as seen in this latest set of spy photos.
Earlier this year, our spies happened to chance upon a prototype of what appears to be a GT4-mule with tacked on panels undergoing tests at the Nurburgring. Fast forward to today, and the GT4 prototype seen here appears more production-ready with smoother body panels and an almost completely revised front and rear bumpers.
The latest revisions made are likely to make the car more aerodynamic. In front, there are larger lower air-intake vents which are also camouflaged, likely to hide the final design of the intakes. Above the intakes, what appears to be corner lights with LED day-time running lights have also been covered. There are also additional vents at the side intakes.
At the rear, the bumper has also been revised and fitted with a new diffuser. The exhaust tips have also been relocated and have been more spaced out compared to units found on the GTS and other 718 models. Completing the GT4 look is the large rear wing.
Apart from the exterior makeover, looking inside one can actually see a roll cage fitted into the prototype. There are also Porsche sports seats installed. Both of these indicate that the prototype is a high performance model.
No details have been revealed about the all-new Cayman GT4's powertrain. Given that the GTS already boasts 365 PS while the previous-gen GT4 produces 385 PS, it is likely that the GT4 could break 400 PS. Unlike other models, the GT4 is also expected to stay naturally aspirated. This comes from Porsche's Andreas Preuninger who said that the GT models will still stay naturally aspirated for one more generation.
