RML P39 reinvents Porsche 911 as 900bhp track monster

Inside, the rear bench is replaced with a half roll cage and the front seats are replaced with new items of RML’s design fitted with four-point safety harnesses.

RML claims that, according to its simulations, the P39 will lap the Nürburgring Nordschleife in 6min 45sec – 4.3sec quicker than Porsche’s official time in the 911 GT3 RS.

Despite the extreme modifications made for the P39, RML said it has ensured the car remains driveable on the open road. It has a special Tour drive mode that increases the ride height and slackens the dampers, helping it to deal with obstacles such as potholes and speed bumps. 

Indeed, RML chief Michael Mallock told Autocar that the company has had the P39 lapping the Nordschleife in the “low 30s” in simulations – putting it within touching distance of the 6min 29sec record recently set by the Mercedes-AMG One – but has intentionally dialled it back to avoid compromising its on-road driveability.

“That was getting a bit too racy as an overall vehicle,” said Mallock. “The main differentiator with this is the ability to be phenomenally quick around the Nordschleife but then to be able to drive back in something that feels more like a Turbo S than a GT3. It’s still got that road usability and comfort.”
