2019 Porsche Cayman GT4 Is The Six-Pot 718 That Purists Have Been Waiting For (Updated)

There were countless upgrades – inside, out, and under the hood – that made the last Porsche Cayman GT4 stand out from “lesser” versions. And so it will be with the new one. But as you can see from these latest spy shots, none will be more obvious than the giant wing protruding from its posterior.

The top of Porsche’s 718 lineup, the new Cayman GT4 (alongside the Boxster Spyder) is expected to pack the 4.0-liter boxer six from the 911 GT3, albeit likely de-tuned for the smaller package, producing just over 400 horsepower. The previous generation Cayman GT4 had a 911 Carrera S-sourced 3.8-liter flat-six with 385PS (380hp).

Porsche has purists covered

Porsche executives have hinted that the new model will be available with both manual and dual-clutch automatic transmission options.

It won’t weight more than the GTS, so expect the GT4 to keep under 1,450kg or 3,200 pounds, which combined with the 4-liter flat six, it should easily beat the previous model’s 0-100km/h time of 4.4 seconds (0-60mph in 4.2sec) and 295km/h (183mph) top speed.

What else should we expect?

Compared to existing versions – including the Cayman GTS – it’ll also have bigger wheels, a stiffer suspension, and a more aggressive aero package that will add a bigger rear spoiler.

That wing looks different than the unit we’ve seen attached to prototypes up to this point. It appears to bear a similar curve and even the same vertical brackets holding it in place, but this one has bigger end-plates. Much bigger, the better to channel airflow and keep it stable at speed.

Big as it is, that in and of itself won’t make the GT4 the unadulterated performance machine that it most definitely will be. But it speaks to the overall package that promises to take the Cayman far beyond the “baby” status to which it was once consigned, and make it every bit the driving tool that Porsche’s other GT models have proven themselves to be… just in a smaller package.

At this rate, we’re hoping it won’t be long before Zuffenhausen (and Weissach) take what remains of the camouflage off the prototype and let us see it in full… and more to the point, tell us what it’ll be capable of doing in the right hands.
