After showing P1 GTR concept last August 2014 at the Pebble Beach Concours d'Elegance in California, McLaren recently announced that the production version of the P1 GTR will make its debut at the 2015 Geneva Motor Show come March.

McLaren reported that the development program for the car has been stepped up during the winter months and has been put through its paces across Europe and around the Middle East. No exact details were disclosed by the British automaker but they did state that the car uses the latest in weight-saving techniques and what the company calls a "track-optimized petrol-electric powertrain". McLaren also stated that the car will have a power-to-weight ratio of 700 PS per tonne.

The aerodynamics and cooling system of the McLaren P1 GTR were also put to the test during the stringent testing, improving over the design that was first used on the concept model that the company debuted last August 2014. Exact power output of the P1 GTR has not yet been revealed though the concept version had 1000 PS.

Testing of the McLaren P1 GTR will continue on through the coming months until its eventual global debut at the 2015 Geneva Motor Show.
