February 19, 2015

McLaren has taken the wraps off their new track-dedicated version of the P1 ahead of its official debut at the 85th International Geneva Motor Show. The GTR moniker first saw use on the string of McLaren F1 GTR race cars built in the mid-1990s (with which the P1 GTR shares its stunning Geneva-bound livery), and denotes that despite being based on road cars, these GTR models are squarely focused on road course supremacy.
The 3.8-liter twin-turbocharged V8 hybrid drivetrain has been dialed in for optimal performance in a track setting, with the V8 dishing now out 789 horsepower and the electric motor offering another 197 ponies, increases of 62 and 21, respectively. That brings the total output up to a fairly outrageous 986 horsepower.
To further bolster track performance, the P1 GTR also sheds some 110 pounds over its road-going counterpart by way of a host of light weight component swaps, including a carbon fiber roof (rather than glass), plexiglass side windows, and a new titanium alloy exhaust that shaves off 14 pounds all on its own.
Without the imperfections of public roads to consider, the engineers in Woking went ahead and lowered the suspension of the supercar by two inches and widened the track by three, while 19-inch alloys wrapped in Pirelli slicks come as standard footwear on the P1 GTR.
The aero kit also sees some retooling, with a large fixed rear wing and revised front splitter helping to boost downforce by ten percent over the road car, which equates to 1455 pounds of downforce at 150 mph. For tracks where top speed is a bigger priority, the DRS (Drag Reduction System) flap from the standard P1 carries over to the P1 GTR, and will allow the driver to change the pitch of the wing from 32° to 0° via a button on the steering wheel.
Similar to Ferrari’s Corse Clienti program provided with the FXX K, the P1 GTR will be part of a bespoke driver’s program which will start at the McLaren Technology Center to have seats fitted, a custom livery designed, and a fitness assessment conducted before heading out for their first track sessions at Silverstone in the UK and Catalunya in Spain.
McLaren P1 GTR will available for ogling alongside the recently announced McLaren 675LT at the Geneva Motor Show in Geneva, Switzerland on Tuesday, March 3rd. Have a look at the video to see the GTR(s) in motion and press release below for additional details. Stay tuned for more updates as we have them.

- McLaren P1™ GTR will premiere alongside the recently announced McLaren 675LT on Stand 1240, Hall 1 at 12.15 CET (11.15 GMT) on Tuesday, 3 March

The track-dedicated 1000PS McLaren P1™ GTR will debut at the 85th International Geneva Motor Show in limited production form with only minor modifications to the Design Concept presented just six months ago. The most noticeable change is the livery that the Geneva show car will be sporting. It is one which will be available to the fortunate few who will be joining the McLaren P1™ GTR Driver Programme that kicks off at the Circuit de Catalunya in Spain later this year. The design is homage to the yellow and green McLaren F1 GTR, chassis #06R, which has claimed its own place in history as one of the five F1 GTRs that dominated the 24 Hours of Le Mans in the historic debut by McLaren 20 years ago.

From design concept to the track

The McLaren P1™ GTR has completed an extensive and intense testing schedule across the world following the unveil of the Design Concept at the Pebble Beach Concours d'Elegance last summer. This has produced enhancements to the original design to optimise aerodynamic performance and cooling.

The front track is 80mm wider than the road-going McLaren P1™ and with its aggressively profiled front splitter, the also car sits 50mm lower to the ground on centre-locking 19-inch motorsport alloy wheels shod with Pirelli slick tyres. 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 fibre 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 50kg over the road-going model.

The rear of the track-only model is dominated, in contrast to the road-going McLaren P1™, by the presence of a fixed-height wing which sits more than 400mm 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 150 mph. Mounted on light weight carbon fibre 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 wheel. 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 6.5kg over the already light road-going system.

Significant updates and modifications to the IPAS powertrain have been made beneath the 'shrinkwrapped' carbon fibre bodywork. At its heart, the McLaren P1™ GTR seamlessly integrates the 3.8-litre twin-turbo V8 petrol engine with an enhanced lightweight electric motor. Combined, these powerplants generate 1,000PS; 800PS (789bhp) is produced by the petrol engine, coupled to 200PS (197bhp) available immediately from the electric motor.

The powertrain has been thoroughly revised for optimum performance on track, with key components replaced with motorsport-developed parts, more suited to the sustained high speed running the cars will be subjected to. In addition to this, features within the powertrain of the McLaren P1™ designed specifically for public highway use have been removed to reduce weight.

McLaren F1 GTR #06R: inspiring a new generation

McLaren F1 GTR chassis #06R was campaigned successfully throughout the 1995 and 1996 seasons with Mach One Racing, and is one of the longest serving examples of the McLaren F1 GTR in competition. The Harrods-sponsored #51 was famously one of seven McLaren F1 GTRs to compete at the 24 Hours of Le Mans in 1995, and was driven to the final podium position by multiple Le Mans race winner Derek Bell, his son Justin, and Andy Wallace. After this result, the team went on to win the final three races of the BPR Championship.

The following year, the team enjoyed another strong campaign. Oliver Grouillard joined Derek Bell and Andy Wallace in the line-up for the 24 Hours of Le Mans, and finished a commendable sixth. The team also claimed a win at Silverstone in the Global GT Endurance championship.

McLaren P1™ Driver Programme

The first locations for the first McLaren P1™ Driver Programme have now been confirmed, and will see drivers attend an initial test session at Silverstone, England, followed by the first on-track activity at Circuit de Catalunya in Spain. These events will follow on from individual driver profiling sessions at the McLaren Technology Centre. These tailored consultations will include a race seat fitting, a Human Performance Centre assessment, and final discussions around the design and livery of each model with McLaren Automotive Design Director Frank Stephenson. Each driver will also experience the McLaren P1™ GTR from the simulator for the first time.

Ultimate Series forms the third and final tier of the McLaren model line-up

The McLaren P1™ GTR joins the road-going McLaren P1™ in the Ultimate Series. This exclusive range prioritises aerodynamics and outright performance through notable advances in weight reduction, chassis and powertrain engineering and the use of pioneering materials.

McLaren has now established a three tier naming structure of Sports Series, Super Series and Ultimate Series. The Sports Series is the entry point to McLaren and will make its global debut at the 2015 New York International Auto Show in April. Above this sits the core McLaren Super Series, comprising the 650S, the Asia-only 625C and the recently-announced 675LT which will premiere at the Geneva Motor Show.

The McLaren P1™ GTR will make its global debut alongside the recently announced McLaren 675LT on Stand 1240, Hall 1 at 12.15 CET (11.15 GMT) on Tuesday, 3 March 2015 at the 85th International Geneva Motor Show.
