After the GT2 RS, the next GT model will be a Cayman GT4 RS, complete with a 4.0-litre engine. So fast is the current four-cylinder Cayman S that Porsche officials privately concede that, if shod with an equivalent tyre, it would be as quick around the Nürburgring as the existing Cayman GT4, so a big performance leap is expected.
Clearly it won’t have the full 500bhp-plus provided to the new GT3, but expect an output of at least 430bhp, a clear 50bhp rise over the Cayman GT4 and more than enough to establish a clear performance margin to lesser, non-GT Cayman models.
