After 16 years Porsche finally gives its mid-engined Cayman sports car the RS treatment, and it’s a blast. The 2022 Porsche 718 Cayman GT4 RS only celebrated the Tuesday evening before the Los Angeles Auto Show, and it packs the 4.0-liter boxer six-cylinder out of the Porsche 911 GT3.

Yes, you’ve read that correctly. Instead of the existing Cayman GT4‘s 4.0 liter engine that was derived from the regular one 911 Carreras 3.0-liter unit without turbocharger, the GT4 RS uses the unique 4.0-liter flat-six of the 992 GT3. In the Cayman, it puts out 493 horsepower and 331 pound-feet of torque, increases of 79 horsepower and 14 lb-ft over the standard GT4 and only slightly less than what the GT3 does. The best part is that the engine of the GT4 RS revs up to a redline of 9,000 rpm, matching the GT3. The existing GT4 redlines at “only” 8,000 rpm, the GT4 RS should have an absolutely insane sound and character – especially with the optional titanium tailpipes.

The only transmission option is a seven-speed dual clutch PDK automatic, which has a shorter gear ratio than the optional PDK in the standard GT4 and in the same manual gearshift design as in the 911 GT3. Porsche says the GT4 RS will reach 60 mph in just 3.2 seconds, half a second faster than the regular GT4 with PDK and at the same time as the GT3, and it will reach a top speed of 196 mph, 9 mph more than the standard GT4 and 1 mph slower than the GT3.

It has the heart of a 911 GT3.


Since this is a Porsche RS model, there are a variety of aerodynamics and chassis changes aimed at achieving maximum track performance. The most noticeable difference is the gooseneck rear wing, which is inspired by the 911 RSR racing car. The GT4 RS also has an adjustable front splitter, new sideblades in front of the front wheels, ventilated front fenders, NACA ducts in the hood, a new rear diffuser and underbody, and wheel air intakes that replace the Cayman’s rear side windows. According to Porsche, the GT4 RS generates up to 25% more downforce than the regular GT4.

The ride height has been lowered by 1.2 inches and the GT4 RS uses 20-inch forged aluminum wheels with central locking, a first for the Cayman. The standard tires are Michelin Pilot Sport Cup 2 or Dunlop Sport Max, but the super sticky Michelin Pilot Sport Cup 2 R rubber is optional. The adjustable suspension has new dampers, revised springs and stabilizers, and new ball joints. Porsche says the GT4 RS is 49 pounds lighter than a PDK-equipped GT4, with weight-saving measures like a lightweight rear window, new door panels with cloth door handles, and a carbon-fiber reinforced plastic construction for the hood and front fenders.

The GT4 RS generates a lot of downforce.


An optional Weissach package gives the bonnet, air intakes, side mirrors and rear wing a carbon finish. The Weissach package also adds titanium exhaust tips, a Porsche logo on the rear window, a Race-Tex suede dashboard, as well as Weissach RS badges and headrest seams. An option for vehicles with Weissach equipment, available at an additional cost, is magnesium wheels, which are available in a radiant Deep Sea Blue finish to match the color of the titanium exhaust when it is hot. Porsche expects around 70% of GT4 RS buyers to equip the Weissach package, similar to the 991 GT3 RS and GT2 RS models. The pictures here show a Euro-Spec model with the Roll Cage Addition Clubsport package, which is not offered in the US.

All of this adds up to an absolute monster on the racetrack. The GT4 RS has already been discontinued a brilliant Nürbugring lap time of 7 minutes and 9.3 seconds by the longer configuration of the track, and on the shorter track previously used, the RS is almost 24 seconds faster than the standard GT4. Porsche’s original goal for the Ring was a time of 7 minutes and 15 seconds – the RS was simply much faster.

Blue wheels!


Porsche GT boss Andreas Preuninger says the GT4 RS is “the most intense car we’ve ever built, including the 911 R,” adding that it “has history as one of the most emotional GT cars of all time will write “. That’s a big claim, but I believe it. Preuninger says the GT department has always wanted to make an RS version of the Cayman as customers have asked for it since the original GT4 came out in 2015, but it had to fit into the car’s lifecycle. “Right now is the best time for the climax.”

When it goes on sale next summer, the GT4 RS will start at $ 143,050 including destination, an increase of $ 40,500 over the standard GT4 but $ 20,700 cheaper than the 911 GT3. The best part? Porsche does not restrict production. The GT4 RS will stay on sale as long as the 718 Cayman, which should be at least a couple of years before the electric replacement for the 718 hits the market by mid-decade.
