We last saw the P1 GTR as a concept during the Monterey Car Week (pictured below). In that form, it boasted the standard version's 3.8-liter twin-turbo V8 but turned the wick up to 986 horsepower, an 83-hp improvement. It also sported a wider front track, lower ride height and mirrors moved to the A-pillars. This latest version appears to further refine the shape of the body, and the gaping front almost looks like it has fangs.
As a track-only model, the GTR is somewhat similar to Ferrari's XX programs. McLaren is promising a full support package to drivers, including time behind the wheel in the company's racing simulator. Actual production for these behemoths isn't set to begin until later in 2015, but watch this teaser for a taste of what's to come in Switzerland.
