|McLaren is set to debut the specially-liveried 1000PS P1 GTR at March’s Geneva Motor Show. Available only to a fortunate few of the McLaren P1 GTR driver program, the P1 GTR is due to embark on its first track run at the Circuit de Catalunya, Spain later in the year.|
Paying tribute to the McLaren F1 GTR chassis no.06R, one of the five F1 GTRs that dominated the 24-hour Le Mans 20 years ago, the P1 GTR version has completed an extensive and intense testing schedule across the world, prior to the official track initiation.
At a glance, the McLaren P1 GTR’s front track is 80 mm wider than the road-going P1 and with its aggressively profiled front splitter, the also car sits 50 mm lower to the ground on center-locking 19-inch motorsport alloy wheels shod with Pirelli slicks. The lower bodywork is trimmed with a sleek aerodynamic blade as previewed on the design concept, which cleans the flow of air along the car’s flanks.
The lightweight windscreen from the McLaren P1 road car, measuring just 3.2mm thick, has been retained, while the side windows are now motorsport-specification polycarbonate with a sliding ‘ticket window’ on the driver’s side. The chemically toughened glass panels in the roof have been replaced with carbon fiber panels to give the cabin a more enclosed, cocooned environment, as has the engine bay cover. The weight saving measures on the McLaren P1 GTR combine to strip out 50 kg over the road-going super sports car.
The rear of P1 GTR has a fixed-height wing which sits more than 400 mm above the sculpted rear bodywork, an increase of over 100mm of the adjustable wing on the road car. Working in conjunction with the front-mounted aerodynamic flaps ahead of the front wheels, the rear wing helps to increase downforce levels by more than 10 percent, meaning up to 660kg at 241 km/h (150 mph). Mounted on light weight carbon fiber pylon supports, the wing retains the DRS (Drag Reduction System) of the road car, which trims the pitch from 32° to 0° at the push of the button on the steering. Another bold and differentiating feature at the rear are the large twin exhaust pipes, formed from an Inconel and titanium alloy. This system saves in excess of 6.5 kg over the already light road-going system.
Significant updates and modifications to the IPAS powertrain have been made beneath the ‘shrinkwrapped’ carbon fiber bodywork. At its heart, the McLaren P1 GTR seamlessly integrates the 3.8-liter twin-turbo V8 petrol engine with an enhanced lightweight electricmotor. Combined, these powerplants generate 1,000PS; 800PS (789bhp) is produced by the petrol engine, coupled to 200PS (197bhp) available immediately from the electric motor.
