最近谍照记者拍到了2018款保时捷718CaymanGT4超高性能版本，这时距离车厂发布2018款CaymanGTS还不到一个月时间。最新谍照显示，GT4最新款已经处于测试阶段，与5月份在纽伯格林赛道拍到的车辆相比，该车的气动布局略有改变。前脸底部重新设计了进气口，至少进气口进行了伪装以掩盖其真实形状。侧进气系统也增加了新的进气口，这似乎与新款CaymanGTS一样。除了车尾更脏以外，后脸也进行了改款，采用了不同的散流器和排气尾管，尾灯组造型也改了，与2018款GTS差不多。仔细观察后窗可以发现车内配备了防滚架，因此可以进一步确定这就是GT4。该车动力系统目前还无法确认，目前已知新款GTS功率365马力，而老款GT4功率385马力，如果新款GT4功率超过400马力将会被更多消费者认可。另外，新车仍将采用自然进气而非涡轮增压引擎。保时捷GT系列老板 Andreas Preuninger表示，GT车系至少未来一代不会采用涡轮增压引擎。不管新车功率是否增加，都将提供手动变速器并可选装PDK 双离合变速器。
2018 Porsche 718 Cayman GT4 Spied With A Dirty Backside
We’re not quite a month past Porsche’s reveal of the 2018 Cayman GTS, but already attention is starting to shift towards what is expected to be a phenomenal ultra-high performance Cayman GT4. These latest spy shots show the latest evolution in the GT4 testing phase, with subtle changes to aerodynamic add-ons from the earlier test car we caught back in May at the Nürburgring. Specifically, the lower fascia sports redesigned air intakes, or at least, intakes wearing some measure of camouflage to hide their real shape. The side intakes have gained some extra vents as well, and appear to be the same production items found on the new Cayman GTS.
Aside from the rear being quite dirty, we also see a different rear fascia with a tweaked diffuser and exhaust tips relocated a bit further to the sides. The taillights have changed as well, matching what we see on the 2018 GTS. Looking really close through the back window we can also see what appears to be a roll cage inside. It would seem this is definitely a GT4.
Power figures are still unconfirmed, though with the new GTS boasting 365 hp and the outgoing GT4 having 385 ponies, it’s widely accepted that the new Cayman GT4 will exceed 400 hp. It’s also believed that the power will come without the benefit of forced induction, as Porsche GT boss Andreas Preuninger has said the GT cars will stay naturally aspirated for at least one more generation. Whether or not there is boost applied to the flat-six engine, power should go though either a manual transmission or an optional PDK dual-clutch gearbox.
