Meet the RML P39, an unapologetic track weapon drawing inspiration from Le Mans hypercars and packing a blistering 900bhp (671kW) under its carbon-fibre skin. RML Group, celebrating 40 years of engineering excellence, has created a machine that promises to "comfortably eclipse" the Nürburgring lap times of the current Porsche 911 GT3 RS. Bold claim, but when you dig into the numbers, it starts to make sense.

RML has taken the already potent Porsche 911 Turbo S and elevated it to a whole new level. The P39 builds on the 992 Turbo S, but after RML’s treatment, there’s not much resemblance to anything coming out of Zuffenhausen. Everything’s been upgraded from the chassis and suspension to the engine and bodywork.

The heart of this beast is an engine boosted from 640bhp (478kW) to a monstrous 900bhp (671kW), thanks to a reworked ECU, larger turbos, new intercoolers, and tuned exhaust manifolds. Torque figures are equally staggering, starting at 800Nm from 3,000rpm and peaking at 1,000Nm from 4,500rpm. Power is fed through Porsche’s eight-speed PDK transmission, so you can expect lightning-fast shifts as it tears around any circuit.

While exact kerb weight figures remain under wraps, expect it to be lighter than the 1,640kg of the 911 Turbo S, thanks to its carbon-fibre body replacing the original aluminium panels. Visually, it takes its cues from Le Mans hypercars, but there’s more than a nod to the legendary Porsche 911 GT1 of the 1990s.

Where the P39 truly flexes its muscles is in the downforce department. The Turbo S may not be Porsche’s most aero-heavy car, but the P39 generates 662kg of downforce at 241km/h, quadrupling the standard model. At 285km/h, it ramps up to 923kg of downforce, easily surpassing the 860kg produced by the 911 GT3 RS at the same speed. A fully adjustable front and rear DRS system allows drivers to tweak these figures to their preference, while hydraulic actuators in the chassis optimise the platform for even more aerodynamic efficiency. When you’re not setting lap records at the Nürburgring, you can engage ‘Tour Mode,’ raising the ride height and softening the suspension for a more road-friendly setup.

The P39’s stance is aggressive too. It’s 100mm wider at both the front (1,683mm) and rear (1,700mm) than the Turbo S, making it wider than even the Porsche 918 Spyder. The wheelbase is stretched by 25mm, with an overall length increase of 170mm to accommodate the radically different bodywork. Wider tyres, 275mm up front and 335mm at the rear provide more grip, wrapped around bespoke forged wheels measuring 20 inches at the front and 21 inches at the rear.

Inside, the cabin retains some familiar 911 elements but adds bespoke touches. Sports seats with custom embroidery and four-point harnesses take centre stage, while the rear seats have been replaced by a custom half cage. It’s a blend of luxury and track-focused functionality that should satisfy even the most hardcore petrol heads.

Only 10 examples of the RML P39 40 Special Edition will be built, each priced at £495,000 plus the cost of a donor car and taxes. Realistically, though, expect the total price to soar close to £1 million once all is said and done. For those lucky few, they’ll own a piece of track-bred history capable of embarrassing some of the world’s most revered hypercars.
