Chronology
Predecessor McLaren F1 (spiritual)

The McLaren P1 is a British limited-production plug-in hybrid sports car produced by McLaren Automotive. Debuted at the 2012 Paris Motor Show,[5] retail began in the UK in October 2013 and all 375 units were sold out by November.[6][7] Production ended in early December 2015.[8] The United States accounted for 34% of the units and Europe for 26%.[8]

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 seconds and the LaFerrari finishing last at 58.58 seconds; the 918 was in-between with 58.46 seconds.[9]

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.[10]

Specifications[edit]

The P1 features a 3,799 cc (3.8 L) twin-turbocharged V8 engine.[11] The twin turbos boost the petrol engine at 1.4 bar to deliver 737 PS (542 kW; 727 hp) at 7,500 rpm and 531 lb⋅ft (720 N⋅m) of torque 4,000 rpm, combined with an in-house-developed electric motor producing 179 PS (132 kW; 177 hp) and 192 lb⋅ft (260 N⋅m) of torque. The electric motor and the petrol engine in the P1, produce a combined power output of 916 PS (674 kW; 903 hp) and 723 lb⋅ft (980 N⋅m) of torque.[12] 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.[13] The car is rear-wheel-drive with a seven-speed dual-clutch gearbox developed by Graziano.

Power for the electric motor is stored in a 324-cell lithium-ion high-density battery pack located behind the cabin, developed by Johnson Matthey Battery Systems. The battery can be charged by the engine or through a plug-in equipment and can be fully charged in two hours. The car can be operated using either the petrol engine, the electric motor or with a combination of the two. The P1 has an all-electric range of at least 10 km (6.2 mi) on the combined European drive cycle.[14] Under the EPA cycle, the range in EV mode is 19 mi (31 km). During EV mode the P1 has a petrol consumption of 4.8g/100 mile, and as a result, EPA's all-electric range is rated as zero. The total range is 330 mi (531 km).[1] The P1 combined fuel economy in EV mode was rated by the EPA at 18 MPGe (13 L petrol equivalent/100 km; 22 mpg-imp petrol equivalent), with an energy consumption of 25 kW-hrs/100 mi and petrol consumption of 4.8 gal-US/100 mi. The combined fuel economy when running only with petrol is 17 mpg‑US (14 L/100 km; 20 mpg‑imp), 16 mpg‑US (15 L/100 km; 19 mpg‑imp) for city driving, and 20 mpg‑US (12 L/100 km; 24 mpg‑imp) in highway.[1][15]

The P1 has Formula 1 derived features such as the Instant Power Assist System (IPAS), which gives an instant boost in acceleration via the electric motor, a Drag Reduction System (DRS) which operates the car's rear wing, thereby increasing straight line speed, and a KERS. Both of these features (IPAS, DRS) are operated via two buttons on the steering wheel. It also generates a downforce of 600 kg at 160 mph[16] and it boasts of drag coefficient of only 0.34.[17]

According to McLaren the P1 accelerates from 0–62 mph (0–100 km/h) in 2.8 seconds, 0–200 km/h (0–124 mph) in 6.8 seconds, and 0–300 km/h (0–186 mph) in 16.5 seconds, making it a full 5.5 seconds faster than the F1, and a standing quarter mile is claimed in 9.8 seconds at 152 mph (245 km/h).[18] Autocar tested 0–60 mph (0–97 km/h) mph in 2.8 seconds, 0–120 mph (0–193 km/h) mph in 6.9 seconds, the standing quarter mile in 10.2 seconds at 147.5 mph (237 km/h), and the standing kilometre in 18.2 seconds at 178.5 mph (287 km/h).[19] The P1 is electronically limited to a top speed of 217 mph (350 km/h). The P1 has a dry weight of 1,395 kg (3,075 lb), giving it a power-to-weight ratio of 647 bhp/tonne. It has a kerb weight of 1,547 kg (3,411 lb)[20] which translates to 593 bhp/ tonne. Actual kerb weight (full tank of fuel, no luggage or people) of US-spec vehicles is 3411 lb. The P1 also features bespoke Pirelli P-Zero Corsa tyres and specially developed carbon-ceramic brakes from Akebono.[21] According to McLaren it takes 6.2 seconds to brake from 186 mph (300 km/h) to standstill, during which it will cover 246 metres. From 97 km/h (60 mph), it will cover 30.2 metres.[2]

Production and sales[edit]

The production version of the McLaren P1 was unveiled at the 2013 Geneva Motor Show.[22] Production was strictly limited to 375 units which, according to McLaren, is to maintain exclusivity. Pricing started at GB£866,000 (€1,030,000 or US$1,350,000)[23] but, as of November 2013, about 75% of P1 customers opted for some level of unique design from McLaren Special Operations, raising the average sale price of a P1 above GB£1 million (€1.2 million or US$1.6 million).[7]

In August 2013 McLaren announced that the production allocation destined to the Americas, Asia-Pacific and the Middle East was sold out.[24] The cars destined for Europe were sold out by mid November 2013.[7] The United States accounted for 34% of the limited production run, and Europe for 26%.[8]

After some delays, production began in October 2013.[25] Hand-assembled by a team of 61 engineers, at a production rate of one car per day McLaren production was planned for fifty P1s by the end of 2013.[26] The first delivery to a retail customer took place at the company's headquarters in Woking, England, in October 2013,[6] with 12 units manufactured by mid November 2013.[7] The first P1 delivery in the U.S. occurred in May 2014.[27] The production run ended in December 2015.[8]

According to JATO Dynamics, only twenty units had been registered worldwide during the first nine months of 2014.[28] A total of 12 P1s were registered in Switzerland during 2014,[29] and an additional five units between January and August 2015.[30] About 59 units were delivered in the U.S. in 2014,[31] and sales in the American market totalled about 127 units delivered through December 2015.[8]

On December 11, 2015, the NHTSA issued a recall for 132 McLaren P1 cars manufactured March 1, 2013, to October 31, 2015 since the hood might open while driving.[32]

Variants[edit]

P1 GTR (2015–2016)[edit]

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.[33] 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.[34]

The P1 GTR's hybrid engine aims to produce 986 bhp (1,000 PS; 735 kW), representing an 83 bhp (84 PS; 62 kW) increase over the standard production P1, although McLaren did not disclose whether the power increase is from electrical boost or tuning the twin turbo 3.8-litre V8. Performance figures remain unconfirmed.[35] The weight of the P1 GTR was reduced by 50 kg (110 lb), achieving a power-to-weight ratio of 687 bhp (697 PS; 512 kW) per 1 tonne (1.1 tons).[36] This equates to a weight-to-power ratio of 1.44 kg (3.17 lb) per brake horsepower. The car also featured slick tyres, and had greater levels of performance, grip, aerodynamics and downforce in comparison to the road car. Featuring a new fixed ride height on race-prepared suspension, a fixed rear wing capable of using DRS, and a new exclusively designed exhaust, McLaren's target was to deliver the ultimate track experience

The P1 GTR can accelerate from 0-60 mph in under 2.8 seconds, and will go on to reach a limited top speed of 217 mph (349 km/h). Additionally, the P1 GTR will brake from 60 mph (97 km/h) to 0 in 85 ft (26 m), and can corner at 1.54 G.[37]

In late 2015, historic racing team and McLaren F1 specialists Lanzante started undergoing road conversions of P1 GTRs for owners who wanted to drive their cars on the road. Thus far, 27 P1 GTRs have been converted for road use by Lanzante.

P1 LM (2016–2017)[edit]

The P1 LM at the 2016 Goodwood Festival of Speed

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.[38] 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).[39]

At the 2016 Goodwood Festival of Speed, the prototype P1 LM, XP1 LM, set the fastest ever time for a road car up the Goodwood hillclimb, with a time of 47.07 seconds, driven by Kenny Bräck.

On 27 April 2017, the prototype P1 LM, XP1 LM, continued its success on track, beating the road car lap record time at the Nürburgring Nordschleife, with a time of 6:43.22 using road legal Pirelli P Zero Trofeo R tyres but without front number plate required to be road legal. This time was once again set by Kenny Bräck, and announced on 26 May 2017.

One-off specials[edit]

P1 GT[edit]

At the 2018 Goodwood Festival of Speed, Lanzante Motorsport, who had previously modified McLaren P1 GTRs to road legal specifications and created the P1 LM, introduced a one-off special based on the P1 GTR. The new car called the P1 GT, is commissioned by a customer from the Middle East and is inspired by the McLaren F1 GT homologation special from the 1990s, including more aggressive body work than the standard car. Exterior modifications include a longer rear section, a larger rear wing, a longer front splitter, vented front fenders, removal of front canards, quad exhaust system in place of the original single outlet design and a modified rear diffuser. The interior features fixed sports seats and alcantara upholstery in tan and green colour along with a racing steering wheel and carbon fibre bits while the exterior features British racing green bodywork paying homage to the original homologation special. Power train modifications and performance figures remain unknown but are likely to have been increased as compared to the standard car owing to the extensive modifications.[40]

Lap records[edit]

McLaren announced a sub-seven minute lap of the Nürburgring Nordschleife, which equates to an average speed in excess of 179 km/h (111 mph), but did not publish the exact time.[41][42] However, the P1 LM, which wasn't road legal during the run, beat the road car record time at the Nordschleife with a time of 6:43.22.

The P1 currently holds the production car lap record at Circuit of the Americas,[43] Algarve International Circuit,[44] Anglesey Coastal Circuit[45] and Silverstone National Circuit.[46][47]
