Porsche is getting ready to unveil the Cayman GT4 RS, which is scheduled for this month, but before that happens our spy photographers caught a GT4 RS prototype testing on public roads free of any camouflage.
This is the first time we get to see the GT4 RS fully uncovered since Porsche’s own prototype reveal had a few patches on the front fenders.

The bodykit looks unsurprisingly more aggressive than any other Cayman, including the GT4. While the front bumper looks quite similar, the splitter is a lot more prominent, featuring larger side fins. The front fenders have integrated gills, the bonnet has two NACA-style intakes, and there is also a new wheel/tire combination – center-lock wheels with optional Michelin Pilot Sport Cup 2 R tires.
On the sides, we can see extra cooling intakes where the rear quarter windows used to be, as well as new side intakes with a separation. The rear end is where the most fun things happen, with a significantly larger swan-neck rear wing benefiting from the lessons learned on the 911 GT3 RS. The side panels of the wing are taped but we can clearly see the GT4 RS emblem hiding below. A mildly tweaked rear diffuser integrating the dual exhaust pipes is rounding up the changes.

As a reminder, the Cayman GT4 RS has clocked an impressive 7:04.511 lap time at the Nürburgring (7:09.300 for the full 20.832 km), which is a whole 23.6 seconds faster than the already very capable GT4.
The model will be fitted with an upgraded version of the mid-mounted naturally aspirated 4.0-liter boxer engine, featuring a “noticeable” power boost compared to the 414 hp (309 kW / 420 PS) of the Cayman GT4, without surpassing the 503 hp (375 kW / 510 PS) of the 911 GT3. Power will be sent to the rear wheels through a PDK gearbox for maximum speed on the track combined with a more aggressive chassis and suspension setup.
We will learn all the details of the new Porsche 718 Cayman GT4 RS in the official debut later this month. Besides Europe, the model is expected to be available in the US market, as noted by another prototype with yellow side markers. Both the Cayman and the Boxster are expected to get fully electric successors previewed from the Mission R concept.
