First shown at a private event at the Pebble Beach Concours d’Elegance, the McLaren P1 GTR concept hinted at a future track-only version of the hybrid supercar. Now the British race team-turned-automaker has revealed more details and images of the production McLaren P1 GTR racer ahead of its 2015 Geneva auto show debut.
Power comes from a 789-hp 3.8-liter twin-turbo V-8 paired with a 197-hp electric motor. Total system output is rated at 986 hp.The standard McLaren P1 road car has a total of 903 hp.
The 986-hp McLaren P1 GTR track car will enter production largely unchanged from the concept shown at Pebble Beach this past summer, according to the automaker, with the biggest change being to the car’s livery, which pays homage to the yellow and green McLaren F1 GTR, chassis #06R, from 1995-1996 24 Hours of Le Mans fame. The exclusive livery will only be available to owners who attend the McLaren P1 GTR Program at the Circuit de Catalunya in Spain scheduled for later this year.
Other changes to the production car include revised aerodynamics to improve high-speed stability and cooling. Changes from the standad P1 include a front track that has been widened by 3.2 inches, a 2.0-inch lower ride height, and center-locking 19-inch alloy wheels wrapped in Pirelli racing slicks. The concept’s aerodynamic blade carries over to the production car to smooth the air flow over the car’s flanks.
While the road car’s lightweight windshield remains, the side windows have been replaced by polycarbonate windows with a sliding “ticket window.” The glass roof panels and engine cover have been replaced with lightweight carbon fiber pieces. Overall, the P1 GTR is 110 pounds lighter than the standard P1.
Out back, the McLaren P1 GTR’s fixed rear wing stands at 15.75 inches high, or 3.9 inches higher than the road car’s adjustable rear wing. That new wing works with the aerodynamic flaps ahead of the front wheels to increase downforce by 10 percent, according to McLaren. Total downforce is said to now equal 1452 pounds at 150 mph. The rear wing retains the driver-adjustable Drag Reduction System (DRS) that can control the pitch of the rear wing from 0 to 32 degrees. The P1 GTR also gets a lightweight Inconel and titanium alloy exhaust with two large tips, saving another 14 pounds.
