In my write-up of the new GT3 RS, I mentioned the Cayman GT4 as a useful alternative for those seeking a traditional manual in their performance car now that Porsche has decided the GT3 RS will no longer come equipped with one. So why not have a look at the new GT4? Like the GT variants with which we are all so familiar for the 911, the Cayman GT4 takes aim at the track. It uses the 3.8 liter flat-six from the 911 Carrera S with 380 hp, sources much of its stiffer suspension from the GT3, and drivers must accept some compromises to refinement and everyday usability in the name of less weight. Those weight savings are countered by weight gains from much of the more stout components on board meaning the GT4 comes in at nearly the same weight as the Cayman GTS. In appearance, the GT4 is clearly distinguished from its siblings by a front fascia akin to that of the GT3 and GT3 RS, its lowered ride height, more pronounced rear air inlets, and a rear wing. Suffice it to say, no one will confuse the GT4 for a standard Cayman. And, of course, the only transmission on offer is a 6-speed manual.
