McLaren P1 GTR unveiled with 1,000 PS hybrid power

Here’s the astonishing McLaren P1 GTR in its limited-production glory. Carrying minimal changes from the so-called P1 GTR design concept shown last year, the final version will make its public debut at the upcoming 2015 Geneva Motor Show with a 1,000 PS hybrid powerplant.

The track-only special sports an 80 mm-wider front track compared to the road-going P1, while the entire car sits 50 mm closer to the ground. Centre-locking 19-inch motorsport wheels with Pirelli slick tyres are featured here, along with an “aerodynamic blade” that trims the lower bodywork.

Round the back, a fixed rear wing is fitted in place of the regular P1’s adjustable unit. It sits 400 mm above the rear bodywork, 100 mm higher than the standard car’s in its tallest position. Total downforce is up by 10% (660 kg at 240 km/h), and the lightweight stands also retain the F1-derived Drag Reduction System (DRS).

The P1 GTR is 50 kg lighter than the road car, thanks to the use of motorsport-spec polycarbonate side windows, carbon-fibre roof and engine cover panels and large twin exhaust pipes formed from an Inconel and titanium alloy. The standard P1 windscreen, already a lightweight 3.2 mm-thick glass, is carried over intact.

In case you’re wondering, the yellow and green livery shown here pays homage to the #06R McLaren F1 GTR, one of five racecars that dominated the 24 Hours of Le Mans in McLaren’s debut year in 1995. If you’re one of the few to buy into the McLaren P1 GTR Driver Programme, you can have it painted any way you’d like, assisted by McLaren Automotive Design Director Frank Stephenson himself.

Underneath the carbon-fibre shell, the P1 GTR boasts a “significantly updated” and track-optimised Instant Power Assist System (IPAS). A 3.8 litre twin-turbo V8 petrol engine generating 800 PS is seamlessly mated to a 200 PS lightweight electric motor, the combination of which amounts to the quoted 1,000 PS total output.

The McLaren P1 GTR now joins the standard P1 in the British firm’s Ultimate Series range – the top of a three-tier structure. The Asia-only 625C, 650S and 675LT (for Longtail, which will debut alongside the P1 GTR in Geneva) make up the mid-level Super Series, while the base McLaren Sports Series will start with the Porsche 911-rivalling P13 model that is set to arrive in April.
