Is there room in the market for another small-volume bespoke hypercar? This British racing and bespoke car building firm things there is. The car is called the RML GT Hypercar, and it’s a Porsche-based rocket. The re-imagined 911 gets a carbon fiber body, active aero and damping, and it makes 920 horsepower from its flat six. It’s designed to go after track records on the weekend, but the company says it can deliver a comfortable ride when you’re on the road the rest of the time.
Inspired By Porsche’s Own 911 GT1
RML – Ray Mallock Limited – says it was inspired by its own motorsports history and by Le Mans racers like the Porsche GT1. So it built this car, which we’ve seen before using the P39 name, to attempt to capture that performance for a very limited few.
The active aerodynamics are serious, starting with the front spoiler that extends three inches forward in Track mode to adjust the car’s balance. Air curtains and vents raise downforce from the 322 pounds of the stock 911 Turbo S the car is based on to 1,147 in road mode and more than 1,461 in Track. Serious performance car numbers, those. If you want high speed, the adjustable rear wing trims drag 23% for straight line speed.
It’s a serious engine, too. The Porsche flat-six makes 920 horsepower and more than 738 pound-feet of torque. It was tuned as part of a partnership with British performance icons Litchfield Motors, and it offers a one-year warranty, over-the-air diagnostics, and a 600-horse Wet mode for when you want a little bit less under your foot.
The cabin has also gotten a very extensive working over. It now has retrimmed seats with contrast-stitching, along with body-matching visual carbon fiber trim elements. Even the roll cage is painted in Storm Purple.
RML’s 39th Project Car Series Marks 40 Years
RML debuted the car at Salon Privé 2025, which is not in France as it might sound, but rather at Blenheim Palace, just north of Oxford in England. The first of just 39 cars shows off the level of customization RML will offer. It has the Performance Pack and Track Packs, including adjustable ride height, a rear roll cage, and no back seat. The GTH also has Storm Purple paint and tinted exposed carbon, along with gold accents to show potential customers how bold they can go with their models.
For this car, 39 is more than just how many it will build. RML has been building racing and road cars since 1984, and this is the 39th of its project cars. Some of those have gone to customers, some were developed for OEMs and are still secret. P31 was the name it used while developing the NIO EP9 EV supercar. That monster EV ran a record 6:45 around the Nürburgring and has set other lap records around the world. For a time, it was the fastest EV in the world. RML then, is a name you might not have heard of, but they’ve got a back catalog of serious performance.
If you missed out on the Porsche 911 GT1 Straßenversion back in the late 1990s, this might be the closest you’re going to find today. RML will be happy to build you one just how you’d like it, as long as you’re one of the next 38 callers, that is.
