McLaren Automotive have released a design concept of the P1 GTR which will be a track focused car for clients willing to pay for exclusive driving days and events, its a homage of the legendary McLaren F1 GTR. The P1 is McLaren’s plugin hybrid supercar and features a 3.8-litre twin-turbocharged V8 petrol engine that delivers 727 bhp (542 kW) and 719 Nm (531 lb ft) at 7500 rpm. The P1 features an in-house developed electric motor that produces 176 bhp (131 kW) and 260 Nm (192 lb ft). The combined total output is 903 bhp (916 PS) and 978 Nm (722 lb ft) respectively. The original F1 GTR was a racing variant, first produced in 1995, it spawned periodic model upgrades and used a modified 600bhp BMW V12 engine. Competition rules at the time dictated the use of an air restrictor making the racing car less powerful than the road car, yet faster and more nimble due to a lowered overall weight. McLaren haven’t revealed the details or spec for the P1 GTR other than it will be debut at the 2014 Pebble Beach Concours d’Elegance on Friday 15, August. We do know the first P1 GTR’s will roll off the production line by 2015.
