The short answer

The McLaren F1 is a 1990s British supercar and the first road car built by the McLaren Formula One team. It used a carbon-fibre monocoque, a naturally aspirated 6,064 cc BMW V12 and a central driving seat. Production ran from 1992 to 1998, with 106 cars built.

The McLaren F1 was the first road-going car that British Formula One team McLaren put into series production. It combined a carbon-fibre monocoque with a naturally aspirated BMW V12 set behind a central driving seat. Between 1992 and 1998 the company completed 106 cars.

The car is remembered as much for its engineering ideas as for its speed. Its designers chased low weight and high power through expensive materials, and they accepted a set of compromises that a more conventional maker would have avoided.

Who designed the McLaren F1?

Chief engineer Gordon Murray conceived the car, and Ron Dennis, then head of McLaren, backed the plan for a road-going sportscar. Peter Stevens was hired to style the exterior and interior, and McLaren Cars was set up to build the car. Murray's goal was the ultimate road-going sportscar.

Murray had been thinking about a three-seat sports car for some time. In 1988 he sketched one while waiting for a flight home from the Italian Grand Prix, and he pitched the idea to Dennis. The concept owed something to Bruce McLaren's M6 GT plans, which served as a reference point for the new car.

Murray also visited Honda's Tochigi Research Centre, and Ayrton Senna went with him. Honda refused to build the engine Murray wanted, a 4.5-litre V10 or V12, so the car ended up with a BMW unit.

Before production, two Ultima MK3 kit cars, numbered 12 and 13, were used as test mules. Both were destroyed once the work was done, which kept the car free of any association with kit cars.

The car was unveiled on 28 May 1992 at The Sporting Club in Monaco. Its safety was first tested in Namibia in April 1993, when an early prototype rolled. A second prototype, XP2, was then built for crash testing later the same year.

How much power did the McLaren F1 make?

The road car used a 6,064 cc BMW S70/2 V12, naturally aspirated, with a compression ratio of 11:1. It produced 461 kW (618 hp; 627 PS) at 7,400 rpm and 650 Nm (479 lb ft) of torque at 5,600 rpm, with the rev limiter set at 7,500 rpm.

Murray insisted on a naturally aspirated engine because it offered reliability and gave the driver direct control. BMW M developed the V12 for the car, and its output came in 14 percent above Murray's original specification for the engine.

The engine weighs 266 kg (586 lb) and is built with an aluminium alloy block and heads. It uses a dry sump lubrication system, and every cylinder bore carries a Nikasil coating for wear resistance. Two Lucas injectors per cylinder feed the combustion chambers.

Fuel economy was never the point. The average figure is 15.2 mpg (15 L/100 km), a number that tells you the engine was built for performance rather than frugality.

Why did the McLaren F1 use a carbon-fibre body?

The F1 was one of the first sportscars with a complete carbon-fibre monocoque. That made it lighter and more streamlined than many later rivals, despite seating three adults. Carbon, titanium, Kevlar, magnesium and gold all appear in its construction.

The most streamlined configuration gives the car a drag coefficient of Cd 0.32 and a frontal area of 1.79 square metres (19.3 sq ft). Two electric Kevlar fans help the underbody create ground-effect downforce, and the driver can switch on a high downforce mode when it is needed.

At the rear, a small dynamic spoiler deploys under heavy braking. When the spoiler is raised, the drag coefficient rises to Cd 0.39, a trade that gives the car extra stability when it is slowing hard from speed.

Heat was a serious issue. The engine bay is lined with gold foil that acts as a heat reflector, and about 16 g of gold went into each car for that purpose. The layout of the engine bay reflects how carefully the team managed thermal load.

The seating layout is unusual. The driver sits in the middle, ahead of the fuel tank and the engine, with a passenger seat on each side. The doors are of the butterfly type, moving up and out, an idea taken from the Toyota Sera.

Weight was the organising principle of the whole project. Carbon fibre, titanium, Kevlar, magnesium and gold were each used where their particular properties suited the job, and the result carries three adults while staying lighter than many later rivals.

How did the McLaren F1 handle and brake?

The F1 uses a double-wishbone suspension, and its weight split is 42 percent front and 58 percent rear. The steering column cannot be adjusted after the car leaves the factory. Each customer specified the wheel and pedal positions before production, so the car was tailored to its owner from the start.

Braking distances are impressive for a road car of its era. From 30-0 mph (48-0 km/h) the car stops in 9.7 m (31.83 ft), from 50-0 mph (80-0 km/h) in 25.2 m (82.68 ft), and from 70-0 mph (112-0 km/h) in 49 m (162 ft).

Carbon brakes were considered but dropped, because the technology was not advanced enough for a road car. Instead the car uses vented Brembo discs, 332 mm at the front and 305 mm at the rear.

The standard car's gearbox is a six-speed manual with a Torsen limited-slip differential that has 40 percent lock. Its clutch and gearbox were developed with Weismann transmissions, so the drivetrain carried a specialist pedigree.

How fast was the McLaren F1?

On 31 March 1998 the XP5 prototype set a production car world record, averaging 240.1 mph (386.4 km/h) over two runs. The result was a benchmark that stood far beyond the car's own era, and it remains the reference point for naturally aspirated performance.

The record was set on the Volkswagen test track at Ehra-Lessien. The F1 is still described as the fastest naturally aspirated production car in the world, a position it has held since that run.

The record was set by a prototype, the XP5, rather than by a racing car, a distinction that matters to anyone comparing the figure with race-prepared machines. It is a road-car benchmark in the purest sense.

Motoring critics noticed the car's pace from the start. Autocar's 1994 road test called the F1 the finest driving machine yet built for the public road.

How many McLaren F1s were built?

Between 1992 and 1998, 106 cars were built across all versions. That total included five prototypes, 64 standard road F1s, five LM cars, one XP1 LM developmental prototype, two GT longtails, one XPGT developmental car and 28 GTR racers. Each car took about three and a half months to make.

McLaren still supports the cars. Every standard F1 carries a modem that lets customer care fetch information from the ECU remotely, and there are eight authorised service centres around the world.

Seven McLaren F1s were imported into the United States by Ameritech. Those cars were modified to be federalised for road use, which changed their equipment and their performance figures.

Did the McLaren F1 race?

Yes. Racing versions followed the road car, and the GTR, LM and GT all came from the same basic design. At the 1995 24 Hours of Le Mans, GTRs finished first, third, fourth, fifth and 13th, beating custom-built prototype sports cars in the process.

Nine F1 GTRs were built for the 1995 season. Air restrictors mandated by the racing rules brought the figure to 441 kW (591 hp; 600 PS) at 7,500 rpm.

The 1996 GTR was developed from the 1995 model, and its weight dropped by around 37 kg (82 lb). One 1996 car became the first non-Japanese winner in the All-Japan Grand Touring Car Championship.

The 1997 GTR was the longtail. Its bodywork was heavily modified, a sequential gearbox was added and the weight fell to 910 kg (2,006 lb). Ten were built for that season, and the extended tail gave the car more downforce.

The F1 LM was built to honour the five GTRs that finished the 1995 Le Mans race. Without race restrictors its engine produced 500 kW (671 hp; 680 PS), and its weight came down to 1,062 kg (2,341 lb). Papaya orange paint was used in memory of Bruce McLaren.

What variants of the McLaren F1 exist?

Beyond the standard road car, McLaren built the LM tribute cars, the High Downforce Kit upgrades, the GT homologation special and the Ameritech imports. Each one shows how the basic design could be adapted for track or road use, and each has its own character.

Two standard cars were upgraded to LM specification, with chassis numbers 073 and 018. Their engines were raised to unrestricted GTR specification, and both received the High Downforce Kit. The upgrades produced 500 kW (671 hp; 680 PS) and gave the cars a stronger track focus.

The F1 GT was the rarest version, built as a homologation special for racing. It kept the extended rear bodywork of the GTR for more downforce, but it had no LM-style rear wing, because the longer tail produced enough downforce on its own.

The upgraded cars kept the road-going character of the original, with the kit adding downforce for track use. Those two cars make the HDK pair a small but notable part of the story.

Customer F1 GTs were built on standard chassis, with numbers 054 and 058. Chassis 058 weighs 1,120 kg (2,469 lb), and a developmental prototype, XPGT, was built before the customer cars went out.
