The 2022 Porsche 718 Cayman GT4 RS has been spied once again without any camouflage whatsoever.
This is almost 24 seconds faster than what its 718 Cayman GT4 little brother achieved.
The GT4 RS prototype was wearing Michelin Pilot Sport Cup 2 R tyres (which will be optional when the RS hits production) during the lap and was equipped with a race seat.
As the hottest-ever 718 Cayman, the lack of camouflage on the prototype shown in the spy photos allows us to have a clearer look at the front spoiler and its corners, the NACA ducts on the bonnet, the additional air vents on the front fender and the 911 GT3-esque swan-neck spoiler.
Other production-ready features that can be seen include the air intakes on the rear corner window, as well as the centre-lock wheels.
The only details that are still covered up for now by stickers are the RS logos on the side of the rear wing and the centre hub of the wheels. Both are clearly visible under the stickers.
What will power the GT4 isn’t clear, but it’s likely to be a development of the 4.0-litre naturally-aspirated flat-six engine in the regular GT4.
“The GT4 RS is one of the sharpest cars Porsche has ever developed,” said development driver Jorg Bergmeister when talking about his experience with the car at the Green Hell.
“And you really have had to experience the breathtaking noise it makes for yourself.”
In the GT4, the flat-six produces 309kW of power and 430Nm of torque when fitted with a PDK dual-clutch transmission, but the GT4 RS could see power boosted to around 375kW if rumours are to be believed.
It’s likely the new GT4 RS will be PDK-only, with the manual reserved for the GT4.
Our spy photographer also noted and shot another GT4 RS with carbon-ceramic brakes, similar in style to the prototype used to record the Nordschleife time.
Expect to see a roll cage, fire extinguisher, and four-point harnesses on the options list for the GT4 RS.
It’s not clear how much the Cayman GT4 RS will cost, but the regular GT4 starts at just below $215,000 before on-road costs. A price tag around the $300,000 mark isn’t guaranteed, but it’s possible.
