Only 375 McLaren P1s rolled off the assembly line between 2013 and 2015, but the track-only P1 GTR is even rarer since only 40 cars were built after production of the standard P1 wrapped up. This example you're looking at here is even more special. Not only is it the first P1 GTR ever built, it was also the first out of a handful converted for road use by Lanzante that added tail lights, turn signals, and a front axle lift system. It's finished in a distinctive yellow and black livery with a red stripe and "01" decals adorning the hood and doors.

Under the hood, the McLaren P1 GTR is powered by a 3.8-liter, twin-turbocharged V8 and an electric motor producing a combined 986 combined horsepower – that's 83 hp more than the regular P1. It's 110 pounds lighter too, enabling the hybrid hypercar to sprint from 0-62 mph in 2.5 seconds before topping out at 225 mph, making it one of the fastest and most powerful road cars in the world.

Some creature comforts have been sacrificed in the pursuit of performance, however. You won't find any leather or Alcantara materials in this car, but it does at least have air conditioning.

Inside, the car's Monocage is exposed, and there's a pair of carbon fiber race seats and a six-point racing harnesses. The steering wheel is borrowed from McLaren's F1 team, complete with controls for the DRS and IPAS system. And just to make it even more desirable, this extreme machine has clocked up just 900 miles since it left the factory in 2016.

If you fancy owning the first ever McLaren P1 GTR ever made, the car is currently for sale at a dealer based in Florida via duPont Registry. No price has been listed, but the P1 GTR would have originally set you back around $2.6 million. We've seen other examples sell for $4 million and as much as $7 million in the past. Considering the rarity of this first example, it's clearly not going to be cheap.
