These two extreme GT cars are coming soon.
2021 will be an exciting year for Porsche sports cars. We've already spotted the next-generation 992 911 GT3 out testing with its 4.0-liter flat-six engine rumored to be producing around 510 horsepower. Alongside the GT3, Porsche will also deliver the most hardcore Cayman variant ever. The upcoming Porsche 718 Cayman GT4 RS has been spotted on numerous occasions, most recently out driving with its big brother, the 911 GT3.
This latest spotting captures the 911 GT3 and 718 Cayman GT4 RS testing on public roads just off the Autobahn, wearing very little camouflage. Aside from a thin black wrap, Porsche isn't doing much to disguise these cars at this point. The "GT3" and "GT4 RS" badges are covered up, but with those massive rear wings, Porsche isn't fooling anyone. With so little camouflaging, the GT4 RS must be inching closer to production.
When these two cars were last spotted, our photographers noticed that the GT3 prototype was painted Gulf Blue underneath its black wrap. While they didn't see what color the GT4 RS is painted, they did manage to get some close-up shots of it, revealing just how extreme it will be. Porsche will equip the GT4 RS with wider fenders, air intakes to replace the side windows, NACA ducts in the hood, larger exhaust pipes, and GT3 RS-style fender outlets.
This prototype is also wearing different wheels than the last time we saw it. The wheels are a center-lock design like those on the 911 GT3 RS, and we suspect will be the ones that will come with the production model. Our spy photographers also sent us some previously unseen shots of the car testing on the Nurburgring, rocking those new center-lock wheels. Behind the driver sits a 4.0-liter flat-six engine rumored to produce 450 hp. The big question on everyone's minds... will it be quicker than the GT3?
