Not that the P1 isn't already a racing-grade car, McLaren thought it could use a few more tweaks to make the ultimate P1 track car. At this summer's Concours in Pebble Beach, the company will unveil the concept for the most extreme, track-only version of the P1, the GTR.
What we know so far is that the car will definitely be built and will begin production in 2015 when the final 375th P1 has been built. The GTR will only be available to P1 owners and will feature enhanced aerodynamics, a wider track, slick tires, and a newly-tweaked engine that will max out at 986 horsepower. Buyers of the car will also get to drive on some of the world's most famous race tracks with a McLaren support team and you will even have access to McLaren fitness consultations and McLaren designer, Frank Stephenson.
