British engineering outfit RML Group has taken the wraps off its limited-run GT Hypercar at the ongoing Salon Privé in the U.K. This build transforms a 992.1 Porsche 911 Turbo S into a Le Mans-inspired machine with performance to match.
For those unaware, Ray Mallock has four decades of championship-winning touring cars and GT programs to his name. From running factory-backed Nissan and Aston Martin race teams to quietly engineering projects for OEMs, Mallock has built RML Group into one of Britain’s most respected and prestigious motorsport firms.
Now, under his family’s leadership, the company has stepped into the spotlight with its most audacious project yet: the GT Hypercar (GTH). Internally known as Project 39, the car marks the company’s 39th bespoke build since the firm’s founding in 1984. Only 39 examples will ever be produced.

So what makes the P39 different from the donor Turbo S? Quite a lot. The car has a distinctive carbon-fiber body, features a stretched wheelbase and wider tracks, and incorporates active aerodynamics, including a splitter and adjustable rear wing with some pretty substantial end plates.
Buyers opting for the Performance and Track Packs will have 920 horsepower at their disposal, selectable ride height, a full roll cage, and a rear seat delete. Torque tops out at 1,000 Nm (about 738 pound-feet) of torque. RML hasn’t confirmed a real-world Nürburgring lap time yet, but simulations suggest somewhere in the low 6:30s, which would place it near the Mercedes-AMG One (6:29.09).
This particular example, revealed at Blenheim Palace, is the first of 1-of-10 40th Anniversary Special Editions, finished in Storm Purple with a carbon-tinted roof and hood, gold wheels, and hand-painted accents. Inside, bespoke Crayon stitching and matching seatbelts contrast with a body-colored roll cage. Also displayed at Salon Privé, the NIO EP9 prototype EV, which set Nürburgring records in 2017, highlights RML’s parallel expertise in combustion and electric projects.


In the U.K., pricing starts at £495,000 (~$666,600) before VAT, but that figure excludes the donor 911 Turbo S. Factor that in, and real-world costs should get the price closer to £700,000 (~$942,650), placing the P39 in rarefied territory. Sources suggest, all 39 builds have already been spoken for.
Also, back in June, RML named Graham Rahal Performance as its official U.S. dealer, setting it apart from most boutique restomod builders, who rarely lock down American distribution so early on. It shows how seriously how RML also views the collector car market Stateside. Finally, while Porsche itself has no halo 918 successor on the horizon, cars like the RML P39 point to a growing movement of Porsche-based hypercar-restomods. Recent standouts include the Tuthill GT1, Kalmar 9×9, and Oilstainlab HF-11.
