The bespoke McLaren Special Operations division was launched in 2011, and offers a full personalisation service for McLaren owners. The dedicated division grew out of McLaren’s Customer Care programme, which goes back more than 20 years to the days of the McLaren F1 roadcar, and continues to look after servicing and maintaining cherished F1s for owners, as well as undertaking personalisation work for all McLaren models.

Commissioned by a North American customer, the McLaren P1™ to be shown features a host of bespoke options which subtly mark this car out, and is on display publicly for the first time. Using the famous McLaren Orange paint throughout to accent the aerodynamic form of the groundbreaking car, the Pebble Beach debut is a showcase of what MSO can offer on the McLaren P1™.

The unique example of the 916PS, 217 mph hypercar is subtly modified to mark this example out from the other 170 examples which have been built to date. At the front, silver finishing to the aluminium radiator grilles sit below the gloss carbon fibre bumper. Above this, a McLaren Orange speedmark adorns the bonnet. On closer inspection, these subtle and considered upgrades run throughout the entire car, and combine to create a truly stunning one-off example.

The bodywork is finished in exclusive Sterling Grey, with the rich metallic finish complemented by gloss carbon fibre, and punctuated by further McLaren Orange accents. Along the profile of the car, brake callipers finished in the heritage colour are mounted behind body-coloured alloy wheels, while an orange ‘P1’ logo on the leading edge of the rear wheelarch is inspired by the labelling used on the test mules during the development of the McLaren P1™.

The dramatic rear of the car is enhanced further by the fitment of 24 carat gold heatshields around the engine bay and inconel exhaust. The material, famously used on the no-compromise McLaren F1 of the 1990s and still used today on McLaren Formula 1™ cars, due to its reflective and heat resistance qualities, is a contrast against the dark paintwork and Satin Nickel-finished Stealth Pack. The upper surface of the twin element rear wing is finished in body colour, while the lower is bare carbon fibre, further amplifying the stealthy appearance. This sits on top of McLaren Orange detailing, with the upper sections of the wing pistons adding further contrast. A bespoke aluminium grille is fitted above the carbon fibre bumper, and is framed by the iconic LED tail light design.

The interior has been tailored with extensive use of carbon fibre and Alcantara®, with the upholstery used on the bespoke MSO steering wheel. The lightweight carbon shell racing seats are fitted with a four-point harness, while further subtle contrasting details feature throughout with Stone Grey binding and stitching on all upholstery, and McLaren Orange accents on the centre console. Custom Satin Nickel-finished airvents mimic the finish found on the exterior exhaust finisher.

McLaren has revealed its new track-focused P1 in its final form, meaning the car will soon start delivery to its eagerly awaiting buyers. It makes its formal debut March 3 at the 2015 Geneva Motor Show where McLaren will also show off the new 675LT, which forms part of the automaker’s mid-level Super Series. The entry-level range is the Sports Series (debuting at April's 2015 New York Auto Show) and the P1 sits in the flagship range which McLaren is calling the Ultimate Series.

This track-only version of the P1 wears the British automaker’s iconic GTR badge, first used on the string of McLaren F1 GTR race cars built in the mid-1990s. F1 GTRs have competed in various motorsport competitions but the car’s most famous accomplishment was overall victory at the 1995 24 Hours of Le Mans. The F1 GTR raced up until 2005 when the final chassis was retired, but now it’s being reborn in the form of the P1 GTR.

We first saw the P1 GTR at last year’s Pebble Beach Concours, but since then it’s undergone an extensive testing program that has seen several modifications made, McLaren tells us. The modifications made are mainly in the areas of aerodynamic performance and cooling. And compared to the ‘regular’ P1 on which it’s based, the new P1 GTR produces more downforce, has more power and weighs less.

The front track is 80 millimeters wider than on the P1 road car, 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 slick tires. The lower bodywork is trimmed with a sleek aerodynamic blade, which cleans the flow of air along the car’s flanks. At the rear is a massive fixed wing, which together with the mods at the front helps boost downforce by 10 percent. McLaren says the P1 GTR produces as much as 1,455 pounds of downforce at 150 mph.

The P1’s twin-turbo 3.8-liter V-8 and electric motor hybrid combo remains, but 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, some parts have been removed to help save weight and others, such as the exhaust system, have been replaced with lighter components. Peak output now stands at 986 horsepower, up 83 hp on the road car (a staggering 789 hp comes from the engine while the electric motor is rated at 197 hp).

Combined weight savings total about 110 lbs. Key items include a titanium exhaust, a lightweight windscreen, carbon fiber replacements for the engine bay panels, and a stripped-out interior.

In addition to revealing the new P1 GTR in its final form, McLaren has confirmed details for a driver development program that the car’s lucky buyers will be entitled to. Run by the McLaren Special Operations team, the program will include specialist driver training, access to the McLaren racing simulator, and maintenance for the cars. Part of the program will also include events held at race tracks all over the globe, where P1 GTR buyers will be able to fly in and drive as well as take part in social events, just like Ferrari’s Corse Clienti program. The first two locations will be the U.K.’s Silverstone and Spain’s Circuit de Catalunya, both of them F1-spec tracks.

That green and gold livery you see here—and others like it—will be one of the options offered to buyers of the P1 GTR. It’s a historic livery inspired by the one on the original F1 GTR with chassis #06R, a car that campaigned successfully throughout the 1995 and 1996 seasons with Mach One Racing and ended up being one of the longest-serving examples of the F1 GTR in competition.

Pricing for the P1 GTR is rumored to start at £1.98 million (approximately $3.36 million), but this includes the car plus the driver development program. Only existing P1 buyers are invited to purchase a P1 GTR, and it’s likely all build slots for the car have been sold.
