Porsche 718 Cayman GT4 RS

The vehicle in detail

Since the Porsche Cayman’s debut in 2006, enthusiasts have praised its exceptional mid-engine balance and dynamic handling. Yet for years, there was a lingering belief that Porsche deliberately capped the Cayman’s potential to ensure it wouldn’t overshadow the flagship 911. That narrative began to shift around 2015, when Andreas Preuninger, head of Porsche’s GT division, was challenged by R&D chief Wolfgang Hatz to explore the possibility of fitting a GT3 engine into the Cayman GT4. As Preuninger later recounted in a Top Gear interview, the idea lingered—and eventually, he surprised Hatz with a test mule powered by a GT3 engine, just in time for his birthday.

That bold experiment ultimately evolved into the production Cayman GT4 RS we know today. It’s no wonder even seasoned Porsche aficionados became infatuated with the finished product. Representing the full RennSport treatment, the GT4 RS boasts lightweight construction, enhanced aerodynamics, sharper handling, and a significant power bump. Under the hood lies a naturally aspirated 4.0-liter flat-six delivering 493 horsepower and revving to a glorious 9,000 rpm, with its signature intake sound amplified by the side-mounted air ducts. After thorough testing, U.S. magazine Car and Driver dubbed it “the no-compromise Cayman we’ve all been waiting for”—a fitting verdict for one of Porsche’s most thrilling modern creations.

Displaying 55 kilometers on the odometer at the time of cataloging, this Belgian-market (C22) GT4 RS Weissach was ordered new by its current and only owner in the stunning grey-green Paint-to-Sample (PTS) shade of Malachite Green Metallic, a hue created for mid-2000s 997-generation 911 so-named after the semi-precious stone. Porsche’s optional PTS program is offered through Porsche Exclusive Manufaktur and remains “must-have” for any modern Porsche. As a coveted Weissach Package-optioned car, it also features a distinctive carbon-fiber weave on the luggage compartment lid, process air intakes, cooling air intakes, airbox cover, exterior mirror upper trims and rear wing, as well as titanium exhaust outlets inspired by the Porsche 935.

Additional desirable exterior and technical options include Porsche’s Front Axle Lift System, Chrono Package, 90-liter fuel tank, Silver-painted GT4 RS forged-aluminum wheels, Smoking Package, Door Pull Loops in Black, and Brack Calipers finished in High Gloss Black. Each individually selected element combines to create a subtle yet striking specification that perfectly suits the sporting nature of the model.

Introduced in 2022, the Cayman GT4 RS marked a first for Porsche and has since become highly sought after by enthusiasts, destined to remain one of the most celebrated and highest-performing Cayman variants ever built.
