McLaren confirmed that its new P1 GTR track-focused model will make its world debut in March, at the 2015 Geneva Motor Show. As you may remember, the McLaren P1 GTR’s design concept was previewed back in August at the Pebble Beach Concours d’Elegance.
According to the British car manufacturer, the new P1 GTR promises to boast a power-to-weight ratio increase in excess of 10 percent over the standard version, to more than 700 hp per tonne. McLaren says that it achieved the performance using motorsport-derived technology and expertise.
Moreover, the vehicle uses a motorsport-optimized 3.8-liter twin-turbo V8 petrol engine as well as the lightweight electric motor. The total output delivered by the hybrid system is 1,000 hp.
When it comes to design, the P1 GTR also features plenty of improvements and as you can see from the photos, it arrives with a more aggressive GT-style front splitter, reprofiled low temperature radiator ducts as well as active aerodynamic flaps.
In addition, the wing mirrors are not located on the A pillars in order to improve the visibility, while the trailing edge of the door-mounted radiator channels were extended.
The vehicle is also fitted with lightweight 19-inch motorsport alloy wheels with quick-release centre locking nuts as well as with a big rear wing fitted with a hydraulically operated Drag Reduction System (DRS). Beneath the wing there is a carbon fiber rear air diffuser that helps the vehicle stay on the ground and very high speeds.
The McLaren P1 GTR has finally completed extensive and intense tests across the world, as commenced after the Design Concept was unveiled at the Pebble Beach Concours d'Elegance last summer. This comprehensive testing schedule allowed McLaren to significantly modify the original design to optimize the P1 GTR’s aerodynamic performance and cooling.
Compared to its street-legal sibling, the P1 GT has a front track that is around 80 mm wider. Likewise, its aggressively profiled front splitter, center-locking 19-inch motorsport alloy wheels and Pirelli slick tires made the P1 GTR sit 50 mm lower to the ground than the P1. Its lower bodywork features a sleek aerodynamic blade – as seen on the design concept – that which cleans airflow along its flanks.
Like the P1 road-going car, the P1 GTR features a lightweight windscreen with a thickness of just 3.2 mm. However, the side windows are now made from motorsport-spec polycarbonate and features a sliding 'ticket window' on the driver's side. The roof and the engine bay cover of the P1 GTR are now made from carbon fiber panels. Overall, McLaren managed to make the P1 GTR around 50 kg lighter than the road-going model.
While the street-legal P1 features an adjustable wing that sits around 300 mm above the rear body work, the P1 GTR features a fixed-height wing mounted 400 mm over the body. Mounted on light weight carbon fiber pylon supports, this rear wing works in conjunction with the front-mounted aerodynamic flaps to increase downforce levels by over 10 percent to 660 kg at 150 mph.
Amazingly, this wing retains the P1’s DRS (Drag Reduction System), which could trim the pitch from 32 degrees to zero with a single push of a button on the steering wheel. The new P1 GTR features large twin exhaust pipes that were formed from an Inconel and titanium alloy, making it more than 6.5 kg lighter than the one fitted on the P1 street-legal car.
