The spy shots reveal a sizable rear wing and aggressive front air-intake with a nod to the 911 GT3’s front-end, while styling otherwise mirrors the ‘toned-down’ models in the Cayman range.
Larger brake rotors than those used to slow the regular Cayman can be seen through the thin-spoke alloys, and the GT4 appears to be wearing larger wheels with lower-profile tyres than other Cayman models.
The GT4 could feature a unique engine in the Cayman range, although the track-performer may continue to offer a version of the current Cayman’s 3.4 litre six-cylinder unit, while future Cayman and Boxster models move to four-cylinder power.
The Cayman GTS with the Sport Chrono package and PDK automatic transmission can reach 100km/h from rest in 4.6 seconds, while the much hotter GT3 will have reached the same speed over one second earlier.
Therefore, we can expect acceleration figures for the GT4 to rest somewhere between these two models, while power output will almost certainly be more than the GTS’s 250kW.
The 2015 Porsche Cayman GT4 is expected to debut at the end of next year, before arriving in showrooms in early 2016.
No word yet on whether Australian showrooms will be among those to offer the GT4, but for now the Boxster and Cayman GTS models are available locally, with the Cayman GTS priced from $161,400 plus on-roads.
