2015 Porsche Cayman GT4 announced, 385 hp from 3.8-litre flat six

The second generation Porsche Cayman receives yet another hotter variant that sits above the 340 hp Cayman GTS. It is so focused that Porsche calls it the GT4, echoing the spirit of the extreme 911 GT3.

It appears to be the wildest Cayman to date, with 385 hp from a 3.8-litre flat-six nicked from the bigger brother 911 Carrera S. Previous generation Cayman R had to make do with only 330 hp.


Externally the GT4 is marginally different from the other Caymans. On the GT4 there’s a new front bumper with a trio of intake openings and a subtle vent just below the badge. A scoop for the side intakes of the Cayman has been added, to channel the air in a more effective way.

The fixed rear wing is fitted as standard and judging by the size of it, it should keep the GT4’s tail planted on the tarmac better than the standard pop-up spoiler on the base Cayman. A diffuser with center exit twin pipes below the simple rear bumper completes the package of this wild Cayman.

The cabin is pure Cayman, beautifully finished and trimmed in leather and Alcantara. Sports seats are standard and there’s a new 918 Spyder-inspired steering wheel wrapped in Alcantara. If you’re trying to find the shift paddles behind the bare buttonless steering wheel you can stop now. Simply because the Cayman GT4 only comes with a manual transmission. Excited yet? Read on.

The 3.8-litre flat six may be slightly detuned from the 400 hp in the 911 Carrera S, but with 385 hp it’s still the most powerful Cayman so far. All 385 horses are transmitted to the rear wheels via a 6-speed manual ‘box with dynamic gearbox mounts. Yes, the hottest Cayman is strictly a manual.

This allows for a sprint time from 0 to 100 km/h is 4.4 seconds, and the Cayman GT4 tops out at 295 km/h. It’s not all about speed either, the GT4’s chassis is said to have been “comprehensively fine-tuned with many components shared with the 911 GT3”.


The Cayman GT4 will make its first public appearance at the Geneva Motor Show in March 2015. Buyers who want more can equip their GT4 with the optional PCCB ceramic brakes, carbon fibre reinforced plastic (CFRP) full bucket seats, a custom Sport Chrono Package with Track Precision app, and a Club Sport Package.
