THE McLaren P1

The McLaren P1 is a British limited-production plug-in hybrid sports car produced by McLaren. Debuted at the 2012 Paris Motor Show, retail began in the UK in October 2013 and all 375 units were sold out by November. Production ended in December 2015. The United States accounted for 34% of the units and Europe for 26%.

It is considered to be the successor to the F1, utilising hybrid power and Formula 1 technology, but does not have the same three-seat layout as its predecessor. Like the F1, the P1 is a mid-engine, rear wheel drive design that used a carbon fibre monocoque and roof structure safety cage concept called MonoCage, which is a development of the MonoCell first used in the MP4-12C and then in subsequent models. Its main competitors were the LaFerrari and the Porsche 918. They are all similar in specifications and performance, and in a race around Silverstone circuit they were all within half a second of each other, the P1 finishing first at 58.24 sec and the LaFerrari finishing last at 58.58 sec; the 918 was in-between with 58.46 sec.

A track-focused version of the P1, the P1 GTR, was unveiled at the 2015 Geneva Motor Show. Production of the GTR was limited to 40 cars.

The P1 features a 3.8-litre twin-turbo V8 petrol engine. The twin turbos boost the petrol engine at 1.4 bar to deliver 727 bhp (737 PS; 542 kW) and 531 lb⋅ft (720 N⋅m) of torque at 7,500 rpm, combined with an in-house-developed electric motor producing 176 bhp (178 PS; 131 kW) and 192 lb⋅ft (260 N⋅m). With both engine and the electric motor, the P1 has a total power and torque output of 903 bhp (916 PS; 673 kW) and 723 lb⋅ft (980 N⋅m) of torque. The electric motor can be deployed manually by the driver or left in automatic mode, whereby the car's ECUs 'torque fill' the gaps in the petrol engine's output, which is considered turbo lag. This gives the powertrain an effective powerband of almost 7,000 rpm. The car is rear-wheel-drive with a seven-speed dual-clutch gearbox developed by Graziano.

Celebrating 20 years since their victory in the 1995 24 Hours of Le Mans, McLaren announced that they would resurrect the GTR name by launching a track-only version of the P1, the P1 GTR.

Production of the P1 GTR was limited to 40 units, initially only available to P1 owners. The concept car made its debut at the 2014 Pebble Beach Concours d'Elegance in August 2014. The P1 GTR production model was officially unveiled at the 2015 Geneva Motor Show. The GTR variant is priced at GB£1.9 million. This price includes a worldwide owners trackday series; later P1 GTRs were offered for less money, approximately GB£1.3 million, for those P1 owners who had no interest in the track series but still wanted to purchase the GTR variant.

The P1 GTR went into production in 2015, after all 375 standard P1's had been built, as a homage to its race-winning ancestor, the iconic F1 GTR and were built, maintained and run by McLaren Special Operations.

With the production run of P1 GTRs having been built and sold, and prompted by their efforts in converting track-only spec P1 GTRs to road-legal spec variants, Lanzante Motorsport commissioned Mclaren Special Operations' Bespoke division to build a further total 6 new P1 GTRs for them to develop into road-legal P1 LM variants. Of this production run, five P1 LMs have been sold and the sixth, the prototype P1 LM, XP1 LM, has been retained and is being used for development and testing. To make them into P1 LM spec, Lanzante Motorsport developed these P1 GTRs by, amongst other modifications, making changes to the drivetrain hardware (to increase power), by employing a modified rear wing and larger front splitter and dive planes (to improve downforce) and by removing the air-jack system and using Inconel catalytic converter pipes and exhaust headers, lightweight fabricated charge coolers, Lexan windows, lighter seats (from the F1 GTR) and titanium exhausts, bolts and fixings (to save weight).
