The Porsche 718 Cayman GT4 is already a hardcore coupe, but it gets an RS version that is even more capable of driving. These spy shots illustrate the development of the nastier model at the Nordschleife of the Nürburgring.
Up front, the RS has a similar fairing to the standard GT4 but has duct tape covering the corners of it. Given the location, the company could hide inlets for brake cooling. The hood gains a pair of NACA ducts. Zooming in on the vehicle reveals rivets on the fenders that appear to be holding a part to the body, which could indicate the vehicle has a wider body.
On the side, Porsche adds louvered entrances to the area previously for the side windows behind the doors. Presumably, these openings would exhaust more air to the engine. The large vent lower on the body is based on the existing GT4.
At the rear, Porsche adds a wing mounted in a swan neck. It is much bigger than that of the standard GT4. The rest of the tail doesn’t look any different.
A rumor suggests that the GT4 RS would use a tuned version of the 4.0-liter flat-six engine. The power could reach 500 horsepower (373 kilowatts), which would be quite powerful in this small coupe.
Expect Porsche to accompany power upgrades with expected performance improvements. A stiffer suspension, better brakes, and additional lightweight components would help cut the extra lap time.
Rumors suggest the Cayman GT4 RS could arrive in late 2021 or early 2022. The price would be around $ 130,000, compared to $ 100,200 for the standard GT4.
