RML P39 40SE Special Edition Celebrates 40 Years With A Nürburgring-Crushing Machine

The UK-based RML Group has just unveiled the P39 40th Special Edition, a hypercar based on the Porsche 992.1 Turbo S, with only 10 units planned for production. Celebrating the firm's 40th anniversary, this limited-edition car boasts high-end upgrades, from its sleek, all-carbon-fiber body to serious performance enhancements under the hood.

RML is shooting for an impressive Nürburgring lap time of 6:45 minutes, which is faster than the Porsche 992 GT3 RS by 4 seconds and an astonishing 32 seconds quicker than the 992 Turbo S that serves as the foundation for this beast. CEO Michael Mallock perfectly summed up RML's goal for the P39 40SE, stating that they aimed to create a car that could comfortably outperform a GT3 RS on the Nürburgring, while still being enjoyable to drive home.

The design draws inspiration from Le Mans Hypercars, with only a few parts like the headlights, mirrors, and door handles carried over from the 911. The P39 40SE features wider fenders, a longer rear end, and active aerodynamics (DRS), making it look as fierce as it performs. The custom wheels—20 inches at the front and 21 at the rear—add to its aggressive stance. The car boasts a track widening by 100 mm and a slightly stretched wheelbase, making it longer, wider, and more stable than the standard 911 Turbo S.

Aerodynamics play a huge role in the P39 40SE's capabilities. At speeds of 285 km/h (177 mph), it generates an incredible 923 kg of downforce—far more than the 204 kg offered by the stock 911 Turbo S. Even at 241 km/h (150 mph), the downforce is still a hefty 662 kg, outclassing even the GT3 RS. Under the hood, RML has supercharged the 3.7-liter twin-turbo engine, boosting it to a staggering 900 hp and 1,000 Nm of torque—significantly higher than the stock Turbo S.

They’ve achieved this by adding upgraded turbos, intercoolers, and a custom Inconel exhaust, among other modifications. For drivers who want more versatility, the P39 40SE offers two driving modes. Track Mode lets you unleash its full potential on the circuit, while Tour Mode raises the ride height and softens the suspension, making it much more comfortable for everyday driving. A roll cage has replaced the rear seats inside, and the new sport seats feature four-point safety harnesses for an enhanced racing experience.

Of course, all this luxury and performance comes at a price. The conversion alone will cost £495,000 ($645,022), not including the Porsche 911 Turbo S donor car. If you don’t already own one, RML can help source it for you. The first of the 10 hypercars is already in production at their Wellingborough facility, marking a new milestone for this celebrated engineering firm.
