- The RML P39 40SE is a limited-production hypercar based on the Porsche 911 Turbo S.
- The model combines a bespoke carbon fiber bodywork with a 900-hp powertrain.
- The conversion costs £495,000 ($645,022) excluding taxes and the cost of the donor car.
UK-based RML Group unveiled the P39 40th Special Edition, a Porsche-based hypercar with a limited production of 10 units. The model is built upon the 992.1 Turbo S but features a bespoke bodywork entirely made of carbon fiber, alongside significant performance upgrades.
As suggested by its name, the P39 40SE was created to celebrate the 40th anniversary of the engineering firm. One of the main goals of the project is to lap the Nurburgring in an estimated 6:45 minutes, 4 seconds faster than the Porsche 992 GT3 RS and a full 32 seconds faster than the 992 Turbo S donor car.

Michael Mallock, CEO of RML Group, said that their goal with the P39 40SE was to create a car that will “comfortably eclipse a GT3 RS at the Nordschleife while being relaxing and easy to drive all the way home again”.
The bespoke carbon fiber body of the P39 40SE is inspired by the current crop of Le Mans Hypercars. The only carry-over parts from the 911 appear to be the lightning units, the mirrors, the greenhouse, and the door handles. The model features wide fenders, a longer tail, active aero components with DRS (Drag Reduction System), and bespoke forged wheels measuring 20 inches at the front and 21 inches at the rear.

Overall, the P39 40SE is 170 mm (6.7 inches) longer and 90 mm (3.5 inches) wider than the 911 Turbo S. The tracks have been widened by 100 mm (3.9 inches), and the wheelbase has been stretched by 15 mm (0.6 inches).
The new bodywork generates an impressive 923 kg (2,035 pounds) of downforce at 285 km/h (177 mph), compared to the 204 kg (450 pounds) of the standard 911 Turbo S. Even at 241 km/h (150 mph), the P39 40SE generates 662 kg (1,460 pounds) of downforce, surpassing the 617 kg (1,360 pounds) figure of the GT3 RS.
Besides the Track Mode, the driver also has access to a Tour Mode. This increases the ride height via hydraulic actuators, and softens the dampers, making it more suitable for road use. The interior features new sport seats with four-point safety harnesses, while the rear bench has been replaced by a half roll-cage.
Last but not least, RML upgraded the twin-turbo 3.7-liter flat-six powertrain to produce an impressive 900 hp (671 kW / 912 PS) and 1,000 Nm (738 lb-ft) of torque. This represents a healthy increase of 259 hp (193 kW / 262 PS) and 200 Nm (148 lb-ft) over a stock 911 Turbo S, made possible by “a new ECU, upgraded turbos and intercoolers, new manifolds and catalytic converters, plus a tuned Inconel sports exhaust”.
Predictably, all the aforementioned upgrades don’t come cheap. According to RML, the conversion alone will set you back £495,000 ($645,022) before taxes, in addition to the cost of a Porsche 911 Turbo S donor car. Thankfully, the company can source these for you if requested. The first of the 10 units of the P39 40SE is already being built at RML’s engineering centre at Wellingborough.
