Porsche only just unveiled the 718 Cayman GT4 and, already, it is being asked about the possibility of an even faster, RS-badged variant.
While speaking with boxer engine development manager Markus Baumann at the recent global launch of the new sports car, Car Sales asked whether the GT4’s 4.0-lite naturally-aspirated six could be upgraded.
“Yes. We could of course get more power,” Baumann responded. “When we take the technologies from the GT3, like the titanium con-rods, or the dry sump… when you apply those technologies to this 9A2 engine it can create much more horsepower than 420 HP. We have those technologies already developed and we could easily bring them together [in 9A2],” Baumann added.

In Cayman GT4 and Boxster Spyder form, this engine pumps out 414 HP and 310 lb-ft (420 Nm) of torque. Those are serious figures, especially for mid-engined sports cars as small as these two. Some customers will inevitably want more, however. When asked about the possibility of the engine’s screaming 8000 rpm redline being lifted further, Baumann said doing so would be possible.
“I would say everything is possible, it’s just a matter of effort,” he said. “It’s a question of model strategy. With a lot of investment into development you can achieve a lot of things with the cars. For now I think for this car 420 HP is enough power. Right now, for strategy reasons, we need to keep a little bit of distance to the 911 GT3 of course.”
It is understandable that Porsche doesn’t want to see a potential Cayman GT4 RS approach 911 GT3 levels of performance. However, we know that the 992-generation GT3 is just around the corner and set to receive more power than ever before, so this could open up room in Porsche’s sports car range to make a GT4 RS viable.
