Watch the RML P39 Unleash 920 HP at Supercar Fest 2025!

RML Group has stunned enthusiasts once again, pulling the wraps off its prototype P39 hypercar at Supercar Fest The Runway 2025. Taking center stage at the high-speed event in Sywell Aerodrome, the P39 represents four decades of British engineering grit turned into motion.

Based on the Porsche 992.1 Turbo S, this is not just another modified sports car. The P39 packs a twin-turbo flat-six engine upgraded in collaboration with Litchfield Motors. The result? A mind-bending 920 horsepower and 705 pound-feet of torque in Sport modes. It can also tone things down with 600 horsepower in Wet mode and 750 horsepower in Normal mode for everyday roads.

The body is entirely re-sculpted in carbon fiber with intelligent active aero, including a rear wing that adjusts for drag and downforce, and a front splitter that moves forward to sharpen turn-in. Downforce climbs from the stock 1,432 newtons to over 6,500 newtons in Track mode at 150 miles per hour.

The suspension has been reengineered too, widening the track and refining damping for all conditions, all while keeping comfort on the road. Three ride modes and a hydraulic lift system offer versatility whether you are on track or in town.

Only 39 of these will be made, with the first deliveries set for late summer 2025. This is not just a car. It is a tribute to 40 years of performance.
