This is the final production version of the McLaren P1 GTR, the ultimate track-only incarnation of the Woking firm’s hypercar.
The 986bhp P1 GTR was first seen in design concept form at the Pebble Beach Concours d’Elegance last August. Now in its final form, the P1 GTR is on display at the Geneva motor show with its design further optimised for aerodynamic performance and cooling.
The Instant Power Assist System powertrain’s output has been significantly boosted over its application in the road-going P1. The twin-turbo 3.8-litre V8 now produces 789bhp (up from 727bhp in the standard P1) and the electric motor has 197bhp (up from 176bhp). The combined output is 986bhp, up from 903bhp. Weight has also been saved by removing powertrain features designed specifically for road use.
The aerodynamic package on the P1 GTR is even more extensive than on the P1 road car. The most striking element is the large, fixed rear wing, which sits 400mm above the bodywork – 100mm more than the adjustable rear wing on the road car at its highest setting.
