Previewed in concept form in Monterey this past summer, the P1 GTR is now ready to hit the track. It's based, of course, on the P1 – Woking's million-dollar flagship hybrid hypercar – but incorporates a long list of upgrades to make it better suited towards ripping around a closed circuit than an open road.
For starters, the 3.8-liter twin-turbo V8 hybrid powertrain has been optimized for track use and retuned: the internal combustion engine cranking out 789 horsepower (up from 727) and the electric motor another 197 (up from 176) for a combined output of 986 hp.
The other side of the power-to-weight ratio has also been optimized, with unnecessary elements removed and many parts replaced by lighter ones: The glass roof and engine cover, for example, have been replaced by carbon fiber, and the side windows by plexiglass. There's also a new Inconel and titanium alloy exhaust that saves 14 pounds all by itself. The result of these and other measures is a drop in curb weight by a solid 110 lbs.
Of course the performance-obsessed engineers in Woking didn't stop there. They also dropped the suspension by two inches and widened the track by over three, riding on 19-inch alloys with Pirelli slicks. The aero has also been revised, with a splitter jutting out the chin and a fixed wing rising a foot and a half taller than the roof, helping the P1 GTR produce 10 percent more downforce than the road car on which it's based. Hit 150 mph on the straightaway and you'd be generating 1,455 lbs of downforce, assuming you haven't activated the Drag Reduction System flap in the rear wing by then. Although it hasn't disclosed the details, and as good as the road-car's stoppers are, McLaren has hopefully upgraded the brakes as well.
Like arch-rival Ferrari's XX client development program (and the path that Aston Martin is tipped to take with the upcoming new Vulcan), the P1 GTR will be part of an organized program. Participating owners will start at the McLaren Technology Centre to have their seats fitted, livery designed and fitness assessed before hitting the first track sessions at Silverstone in the UK and Catalunya in Spain.
Before that, though, the P1 GTR will be showcased in this special livery – reminiscent of the legendary #06R Harrods-sponsored McLaren F1 GTR – at the Geneva Motor Show. It joins the P1 in McLaren's new Ultimate Series, positioned above the upcoming Sports Series, and the existing Super Series made up of the 650S and the new 675LT also debuting at the Swiss expo.

- McLaren P1™ GTR Driver Programme confirms first locations
- Geneva Show car livery inspired by iconic McLaren F1 GTR, chassis #06R
- 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.
