Dubbed as the most powerful and most exclusive McLaren model to-date, the new P1 GTR will make its world premiere in production guise at the Geneva Motor Show in March.

This follows the display of the P1 GTR Design Concept in racing livery at the Pebble Beach Concours d’Elegance last August where McLaren had confirmed initial specifications for the track-only model (sorry, you can’t use the GTR on the road…).

Free from the restrictions of street-legal regulations, McLaren engineers were able to improve the P1’s aerodynamics using more extreme solutions such as the huge rear wing, front splitter, extra aero and cooling features on the sides, repositioned mirrors, redesigned rear diffuser, and a lowered chassis.

The GTR also rides on a wider front track and new slick tires, while output from the 3.8-liter twin-turbo V8 and electric motor combination was raised from 903hp to 986hp.

According to McLaren, all these changes along with a number of weight-saving measures help the GTR boast a power-to-weight ratio increase in excess of 10 percent over the road-going model, to more than 700PS (691hp) per tonne.

The British firm said that recent tests across Europe and the Middle East “have pushed the performance of the car to its limits, and have been designed to further enhance cooling and aerodynamics over the design concept”.

McLaren plans to begin production of the P1 GTR in very limited numbers later this year.
