Model history: Talented South African designer Gordon Murray was pretty much given carte blanche to design the world's best and fastest driver's car. This McLaren would go head to head with Ferrari, Porsche and Lamborghini exotic street machines. Murray's curriculum vitae already sported several championship winning F1 cars, including the 1988 McLaren MP4/4. Murray first informed the world of McLaren's plans in 1989 when he showed a design sketch of the upcoming Formula 1 inspired supercar. It would take another three years, before the aptly named McLaren F1 was shown to the public at the start of the Monaco Grand Prix weekend. That race was fittingly won by McLaren's Ayrton Senna. It was not his only road car project as in his spare time Murray was also working on another unique car that would be later sold as the 'Light Car Company Rocket'. This motorcycle-engined machine was built to a completely different concept and specs than the McLaren road car, so the two projects did not conflict. Generally speaking, supercars are 'no compromise' driving machines with performance as the main focus with little need for practicality and/or comfort. Never easily pleased, Murray wanted the tarmac-shredding performance but wouldn't compromise on practicality and comfort. To ensure there was plenty of performance, he made the car as light as possible; engine power might overcome the weight in a straight line, but during braking and cornering every kilogram counted. This was achieved by using a host of exotic and composite materials, with carbon fibre the most prominent. Murray's solution for making the McLaren F1 practical was to install three seats with an F1-inspired central driver seat mounted slightly ahead of the adjacent passenger seats. This setup was already used in a Ferrari concept car of the 1960s, but never made it into production. The interior also featured a highly advanced cd-player, but no radio. Ahead of both rear wheels there were two storage bins that could take as much luggage as a small hatchback of the day. To provide the driver with a genuine direct feel and again to save weight, advanced driving aids like a 'flappy-paddle gearbox', ABS, power steering and traction control were not fitted. Murray used his connections with BMW dating back from his Brabham days to broker a deal with the company's engine specialist Paul Rosche to supply a bespoke V12 engine. In keeping with the F1's design philosophy, the engine had to be both lightweight and powerful. BMW not only met the requirements, but with its 6.1 litre, 627 bhp V12 engine exceeded the 550 bhp set, although it was slightly heavier than asked for. The lightweight V12 engine was mounted amidships and mated to a McLaren-developed six speed manual gearbox. To better insulate the heat from the tight engine bay, the engine and exhaust covers were covered in gold, which is highly reflective. Missing from the very slippery Peter Stevens designed exterior, was a big wing that thanks to the likes of Ferrari and Lamborghini had become a super trademark. Banned by that time in Formula 1, Murray was free to use ground effects and moving aerodynamics for the McLaren road car. Reminiscent to his 1978 Brabham F1 car, the McLaren F1 was fitted with two electric fans to suck the car to the ground. Hidden when stationary, the car also sported a small moveable wing on the tail of the car that offered stability at high speed, served as an airbrake and an additional cooling vent for the rear brakes. These advanced devices provided plenty of downforce, but without the drag created by the familiar big wings. In the months after the Monaco launch, five prototypes were constructed and tested extensively in every thinkable condition. One was destroyed in Namibia during these tests and another was sacrificed in a mandatory crash test. It was not until late in 1993 that the McLaren was ready for production. Not surprisingly the car was received to universal acclaim thanks to its benchmark performance, superb packaging and immaculate fit and finish. A slight problem was the sticker price of 540,000 Pounds (excluding taxes), which not only made it the fastest production car in the world, but also the most expensive. This was particularly troublesome as the market for classic and exotic machines had just collapsed after the ridiculous price surges of the late 1980s. There was nevertheless a demand for Murray's masterpiece and production commenced. Another reason why the McLaren F1 never became a top seller was that the company never had the car certified for the United States. This would have involved sacrificing several more cars for crash testing and the addition of more advanced safety items like airbags. Between 1993 and 1998 a total of just 64 McLaren F1 road cars were constructed. Not surprisingly, there was an immediate interest in a racing version of the McLaren F1. As mentioned earlier, the car was not designed with racing in mind, but with little effort it could be converted to comply with the GT1 regulations used in the BPR championship and most importantly at Le Mans. There were no funds to enter GT racing with a Works team, but it was calculated that the development costs could be covered if five racing cars were sold to customers. In addition to the mandatory safety equipment the F1 GTR sported a large rear wing, carbon ceramic brakes and the suspension was stiffened by replacing the rubber bushings with solid aluminium ones. To cool the driver and the gearbox, some additional vents were also cut in the carbon fibre bodywork. Courtesy of the lighter brakes and a stripped interior the racing version was 100 kg lighter than the road car. BMW modified the engine to work with the mandatory restrictors. It proved to be a great success both in the salesroom and on the track; nine examples were constructed in 1995 and ten victories were scored. The debut season of the F1 GTR was highlighted by a much coveted win in the legendary 24 Hours of Le Mans. Amazingly five of the seven cars entered lead the race at one point and at the end of the race McLaren also held the third, fourth, fifth and thirteenth position. To commemorate the Le Mans win, McLaren produced the limited edition F1 LM late in 1995. It used a restrictor-free version of the GTR engine, which produced a staggering 680 bhp. The big rear wing was also carried over from the racing car. One prototype and five (the number of cars that finished the 1995 Le Mans) production cars were constructed, most of which were painted in the striking papaya orange also used for the company's legendary Can-Am cars. For the 1996 season, a second generation of the GTR was developed. The car was lowered further and made lighter courtesy of a magnesium gearbox casing. A longer front splitter was also fitted. Another nine cars were constructed and despite strong competition from the newly developed F40 GTE, all nine BPR races were won. The tally was further increased with five victories in the All-Japan GT Championship. At Le Mans, the F1 GTR was not able to keep with the intrinsically faster prototypes. The success of the McLaren F1 GTR had other companies interested and in 1997, the British team faced opposition from the likes of Porsche, Mercedes-Benz and Nissan. Unlike McLaren, they had constructed purpose-built racing cars with the derived road cars built for homologation purposes only. McLaren anticipated the stronger competition with a third evolution of the GTR, which sported a completely different and much longer body. It was also considerably lighter, only weighing 915 kg. A sequential gearbox was also installed. For homologation purposes, McLaren constructed three road cars with the 1997 style body, dubbed the F1 GT. BMW had also taken an interest and bought several of the ten 1997 spec GTRs and raced them in what was now known as the FIA GT Championship. BMW Motorsport scored five victories that year in the championship. Le Mans was again a trophy for the prototypes, but with a second and third place, the F1 GTR took the top two positions in the highly competitive GT1 class. It's fitting that the final chapter in the McLaren F1 history was again written by the road car, when it broke the production car speed record in 1998, clocking 240 mph at Ehra-Leissen in Germany. The McLaren F1 remained the supreme supercar for many years and with a racing record to match, it has gone into history as one of the classic GT racers in the tradition of the Ferrari 250 GTO and Porsche 911 RS. The next generation supercars that finally surpassed the performance benchmarks still do not offer the McLaren's complete package and most certainly do no have the car's immaculate racing record. The only blemish on the car's record is the failure to come anywhere near the proposed production number of 300. A few years later Murray helped McLaren and Mercedes-Benz design the rather bulky SLR, which did not come close in any respect to the fabled F1. He is now in the process of designing and producing a revolutionary lightweight (of course) city car. McLaren have more recently re-entered their road car business with the MP4-12C sports car and at the time of writing the P1 supercar is being developed, which can be considered the F1's spiritual successor.
