McLaren has just showcased the production version of the P1 GTR at the 2015 Geneva Motor Show.
Described as the “best driver's car in the world on track”, the P1 GTR is 50 kg lighter than its road-going sibling thanks to the use of polycarbonate side windows, carbon fiber panels in the roof and engine bay. The dual exhaust pipes are made from Inconel and titanium alloy which has helped shave off more than 6.5 kg.
The twin-turbo 3.8-liter V8 engine has been revised and it now develops 800 hp and works with an uprated electric motor generating 200 hp which allows the P1 GTR provide a combined output of 1,000 hp. The added output was obtained by installing several motorsport-spec components while some of the features necessary for the road-legal P1 have been eliminated as part of the massive diet.
The track-only model is 80 mm wider than the standard car and also it sits 50 mm lower. It rides on 19-inch alloy wheels with center-locking system and Pirelli slick tires. The most noticeable change at the back is represented by the massive fixed wing sitting 400 mm above the rear bodywork, representing a 100 mm increase over the P1’s adjustable wing. Downforce has been boosted by 10 percent and now stands at 660 kg at 241 km/h.
