Porsche puts the 911 on the GT4 grid for the first time

Porsche has moved its GT4 project onto the 911 platform for the first time: the new 911 GT4 R replaces the discontinued 718 Cayman GT4 RS Clubsport. For customer teams, this is more than a body swap — it is a step up to a more expensive, more mature racing base. The car is built on the 992.2 911 Cup, while its engine is inherited from the road-going 911 GT3.

At the heart of the newcomer is a 4.0-litre flat-six. Peak output reaches 520 hp and 470 Nm, but in actual racing the numbers will depend on the Balance of Performance: the car leaves the factory with 53.7 mm air restrictors that trim power to 430 hp. The transmission is a six-speed sequential dog-box with paddle shifters and a four-disc racing clutch.

The 911 GT4 R differs from the previous Cayman in more than just layout. It has wider track widths, more sophisticated racing electronics, a 10.3-inch digital display, an integrated data logger, a precise GPS system for lap analysis and ballast settings tailored to BoP. The aero is also flexible: the rear wing is manually adjustable across 11 positions, while the doors, body kit components and engine cover are made from natural-fibre-reinforced plastic.

The U.S. price is $375,500 including import and delivery. That is the level where buyers no longer pay for status, but for lap times and reliable factory support in racing series. Porsche has already homologated the 911 GT4 R for SRO GT4 America, the IMSA Michelin Pilot Challenge and a number of factory-backed one-make cups, with its racing debut scheduled for the 2027 season.

The switch from Cayman to 911 could reshape the GT4 landscape: Porsche gains a more recognisable model, teams move closer to the upper classes in terms of technology, and the Cayman bows out for good from its role as the brand's entry-level racing ticket.
