In a small corner of McLaren’s sprawling headquarters in Woking, England is a small shed set up for the P1 GTR. In case you’re not familiar with the car, it’s a more extreme version of the P1 supercar designed and built exclusively for the track, meaning the engineers weren’t limited by any regulations or design rules when coming up with the specifications.

McLaren is building just 50 examples, with build slots offered exclusively to existing P1 owners, and typically the cars are kept and maintained by McLaren in this small, dedicated facility that the automaker has opened up to the outside world for the first time. Here, the cars sit before being shipped out to top race tracks around the world as part of a driver development program for owners.

The first stop was in Barcelona, Spain. The event took place back in October and each of the cars involved received a special badge to mark the occasion. Furthermore, you’ll notice that pretty much all of the P1 GTRs have special liveries. That’s because McLaren’s own design chief Frank Stephenson worked closely with owners to come up with a unique look for each of the cars.

The interiors are also customized. For example, each owner is fitted for a unique carbon fiber seat, and measured for a tailor-made race suit and helmet. They spend time with a personal fitness trainer too, and together with their driver coach, undergo simulator sessions in the same facilities utilized by the drivers of the McLaren Formula One team.

The P1 GTR features the same hybrid drivetrain used in the P1 but its electric drive system and twin-turbocharged 3.8-liter V-8 have been tuned for improved performance. It has a peak output of 986 horsepower, up 83 hp on the road car, and it also benefits from lighter weight, a wider track and more downforce.

McLaren says the P1 GTR produces as much as 1,455 pounds of downforce at 150 mph, which is roughly 10 percent more than the road car. This is due to unique aerodynamic enhancements including a larger front splitter and carbon fiber canards. The mirrors have also been moved to the A-pillars, putting them closer to the eye line of the driver and reducing aerodynamic drag. And at the rear is a bigger wing complete with drag reduction system.

Note, not all P1 GTRs are kept here. Some owners, like Bruce Canepa, have chosen to take their cars home.
