McLaren has been teasing us with its upcoming P1 GTR for some time now, and finally, we are getting our first peek at this track-exclusive monster ahead of its Geneva debut. The P1 GTR’s updated body consists of a new splitter, a new 400 mm fixed wing (300 mm taller than stock), and an adjustable front wing to create 660 kg of downforce at 150 mph — a 10 percent increase over the P1. Additionally, the P1 GTR is 80 mm wider and 50 mm lower than the standard model.
The body of the display car that McLaren is showing off here is painted in the iconic yellow and green livery that the McLaren F1 GTR chassis no. 06R wore in the 24 Hours of Le Mans two decades ago.
Dropping weight was a huge part of the GTR program, but given the P1 was already pretty light, McLaren could only shave off an extra 50 kg. It achieved this by installing a 3.2 mm windshield, polycarbonate side windows, a 6.5 kg lighter Inconel and titanium exhaust system, and carbon-fiber panels in place of the roof glass.
At the corners of the GTR are race-ready center-locking 19-inch alloy wheels wrapped up in Perilli slicks.
Under the hood is the same twin-turbo 3.8-liter V-8 and the electric motor that the road-going P1 has, but with a twist. In the road-legal model, this the gasoline engine lays down 737 PS (727 horsepower) and the electric motor puts down 179 PS (176 horsepower) for a combined 916 PS (903 horsepower), but the P1 GTR is retuned to 1000 PS (986 horsepower). This is broken down into 800 PS (789 horsepower) from the gasoline engine and 200 PS (197-horsepower) from the electric motor.
While that may not sound like a huge bump for a race car, keep in mind that many race cars don’t produce much more power than their road-going counterparts – actually some produce less power – as the main focus is in making the engine as efficient and reliable as possible.
We’ll learn more about the P1 GTR at the Geneva Auto Show on March 3, 2015, and we’ll get to see it in action at the Circuit de Catalunya in Spain later in 2015.
