Porsche 718 Cayman GT4 RS - 17 Years in the Making

Kawe S

Taking the baton from the 718 Cayman GT4, the all-new 718 Cayman GT4 RS has, if anything, taken a little too long to arrive. After years of hoping and waiting, it is finally here, and Cayman fans like us can hardly contain their excitement.


This update is the first RS since the Cayman ranges’ premiere in 2005. The 2021 GT4 RS is designed to be a racecar for the road. A promise that it delivers with its high-tech aerodynamics package, lightweight design, powerful engine, and deafening sound that will most likely have you banned from your neighborhood.

All jokes aside, the GT4 RS packs some serious upgrades. For those looking for an upgrade, these make it the most capable road-going 718 Cayman they can get their hands on.

Engine and Performance

Unlike the GT4, the GT4 RS borrows the 911 GT3’s 4.0-liter flat-six engine, which, in this case, produces a respectable 493 horsepower. Torque is stated as 331 lb-ft, and many will be happy to know that just like with the 911 GT3, the engine still hits that obscene 9000 rpm redline.

Performance-wise, the new car does the traditional 0-60 mph in a respectable 3.2 seconds, while its top speed sits at 196 mph. Porsche even shared their Nürburgring lap times, revealing that the new GT4 RS set a lap of 7:04.511 minutes on the 20.6 km shorter track variant.

For context, the standard Cayman GT4 comes packed with 414 hp and reaches 60 mph from a standstill half a second slower than the new RS. The car also sets an inferior time on the same Nürburgring configuration, adding a full 23.6 seconds to the Cayman GT4 RS’ lap time.

Stubborn as it already sounds, the RS stays true to RS tradition, exclusively employing Porsche’s in-house PDK seven-speed dual-clutch transmission for gear shifting duties. The PDK gearbox, in this case, features much shorter gearing than the one found in the standard GT4.

Design and bodywork

Not much has changed in terms of the overall design. However, Porsche has added several tweaks and components aimed at making the car lighter and, of course, more efficient.

The RS has a new set of air intakes behind the side windows. These replace the small window on other 718 Cayman models. These not only set the car apart from its predecessor but, most importantly, improve the airflow. That the car’s lucky occupants can hear this is a big bonus.

Other noticeable inclusions include the swan-neck fixed rear wing (borrowed from the 911 RSR race car and the 911 GT3), and 20-inch forged aluminum wheels.

Porsche mentions that the Cayman GT4 RS was constructed with a focus on weight reduction so, the company opted for the extensive use of lightweight composite materials.

Case in point are the car’s front fenders and hood. Both are constructed from lightweight carbon fiber, while the rear window’s construction is of lightweight glass. Add to these the lightweight door panels, and you have a car that is 49 lbs. lighter than the regular 718 Cayman GT4.

The Porsche 718 Cayman GT4 RS will cost prospective owners a minimum of $141,700 and should be available at US dealerships “in the course of summer 2022.” The good news is, it’s not a limited-edition car, so everyone who wants one can become an owner.
