This Porsche 911 Just Became a 907 HP GT Hypercar : Automotive Addicts

Automotive

Standing out in a world full of tuned 911s is tough, yet RML Group’s new GT Hypercar makes it look easy. Originally shown as the P39 prototype last fall, the production-ready version has arrived with wild aero, serious chassis work, and a power figure that reads like a typo. Try 907 horsepower from a heavily reworked 3.8 liter flat six. The result is a road legal special that looks built to hunt lap records while still wearing plates.

The foundation is the 992.1 generation Porsche 911 Turbo S. RML stretches the template by extending the wheelbase and pushing out the front and rear tracks, then layers on active aerodynamics. There is a taller adjustable rear spoiler and a prominent front splitter, both aimed at cranking up downforce and stability at speed. The overall stance pays a clear nod to the 1998 Le Mans winning Porsche GT1, and the visual drama is matched by function.

Under the engine cover sits Porsche’s familiar twin turbo 3.8 that has been torn down and rebuilt with Litchfield Motors involved on the power side. Output now lands at 907 horsepower and 738 pound feet of torque. RML has not spelled out the transmission, though the factory Turbo S uses an eight speed dual clutch, and that is the logical pairing for something with this much shove. Expect all wheel drive traction and an aggressive calibration to make full use of the added power.

The chassis reads like a greatest hits list for track days. Buyers can spec Performance Pack and Track Pack on the 10 car Special Edition run, which adds adjustable ride height, a rear roll cage, and removal of the rear seats for weight savings. Brakes, cooling, and aero have all been addressed, and the suspension geometry takes advantage of those wider tracks for better bite on turn in. It is a comprehensive rethink rather than a simple tune and body kit.

Despite the focus on lap time, RML says the GT Hypercar remains fully legal for the street. That matters because the company has made no secret of the target playground. When the P39 first surfaced, the claimed Nürburgring potential was 6 minutes 45 seconds. The new goal is closer to 6 minutes 30 seconds. For context, that would land it ahead of some heavyweight names and comfortably quicker than a 911 GT2 RS with Manthey setup. Ambitious, yes, but the ingredients are there.

The cabin gets the same obsessive approach. Expect race grade materials, purposeful seating, and a driving position that feels closer to a GT racer than a grand tourer. The details matter on cars like this, and RML leans into that with custom switchgear, simplified interfaces, and a focus on keeping the driver locked in and undistracted. The effect is more focused 911 than luxury coupe.

Only 39 GT Hypercars will be built, a neat nod to the 39 prototypes used during development. Of those, 10 are Special Edition cars like the one shown here, bundling the most aggressive hardware into a limited package. Pricing has not been announced, but the combination of low volumes, bespoke engineering, and Porsche Turbo S hardware suggests this will sit firmly in rarefied air.

RML’s leadership frames the project as a showcase for what the British engineering outfit does best. The timeline from P39 concept to GT Hypercar has been quick, the execution looks costly, and the end product feels like a proper bridge between motorsport and the road. It is the kind of car that turns heads on the street and turns laps when the helmet goes on.

The public debut took place at Salon Privé in the United Kingdom, which is fitting given the car’s blend of coachbuilt style and high tech engineering. Order books are open. If the Nürburgring number happens, the GT Hypercar will be a headline machine. If it simply comes close, it will still be one of the most outrageous 911 based builds of the decade. Either way, this is a big statement from RML and a thrilling new chapter for Porsche based specials.
