McLaren GT
The final incarnation of the roadcar, the F1 GT was meant as a homologation special. With increased competition from homologated sports cars from Porsche and Mercedes-Benz in the former BPR Global GT Series and new FIA GT Championship, McLaren required extensive modification to the F1 GTR in order to remain competitive. These modifications were so vast that McLaren would be required to build a production road-legal car on which to base the new race cars.
The F1 GT featured the same extended rear bodywork as the GTRs for increased downforce and reduced drag, yet lacked the rear wing that had been seen on the F1 LM.The downforce generated by the longer tail was found to be sufficient to not require the wing. The front end was also similar to the racing car, with extra louvers and the wheel fenders widened to fit larger wheels. The interior was modified and a racing steering wheel was included in place of the standard unit.
The F1 GTs were built from standard F1 road car chassis, retaining their production numbers. The prototype GT, known as XPGT, was F1 chassis #056, and is still kept by McLaren. The company technically only needed to build one car and did not even have to sell it. However, demand from customers drove McLaren to build two production versions that were sold. The customer F1 GTs were chassis #054 and #058.

On March 31 1998 it set the record for the fastest production car in the world 240.1 mph (386.7 km/h) [1] which record it held until 2005. [2] As of January 2009 the F1 is the fastest naturally aspirated production car.[1] The car features a 6.1-litre BMW S70 60° V12 engine and it was conceived as an exercise in creating what its designers hoped would be considered the ultimate road car. Only 106 cars were manufactured 64 of those were street versions (F1) 5 were LMs 3 were longtail roadcars (GT) 5 prototypes (XP) 28 racecars (GTR) and 1 LM prototype (XP LM). Production began in 1992 and ended in 1998.[3] Contents [hide] * 1 Design and implementation o 1.1 Engine + 1.1.1 History + 1.1.2 Specifications o 1.2 Chassis and body o 1.3 Aerodynamics o 1.4 Suspension o 1.5 Tyres o 1.6 Brakes o 1.7 Gearbox and miscellaneous o 1.8 Equipment o 1.9 Purchase and maintenance o 1.10 Performance + 1.10.1 Acceleration + 1.10.2 Top speed + 1.10.3 Cornering + 1.10.4 Braking + 1.10.5 Track tests * 2 Record claims * 3 Variants o 3.1 Prototypes o 3.2 F1 LM o 3.3 F1 GT * 4 Motorsports o 4.1 F1 GTR \'95 o 4.2 F1 GTR \'96 o 4.3 F1 GTR \'97 * 5 Replicas and Models * 6 References * 7 External links [edit] Design and implementation Chief engineer Gordon Murray\'s design concept was a common one among designers of high-performance cars: low weight and high power. This was achieved through use of high-tech and expensive materials like carbon fibre titanium gold magnesium and kevlar. The F1 was one of the first production cars to use a carbon-fibre monocoque. The three seat setup inside an F1. The idea was first conceived when Murray was waiting for a flight home from the fateful Italian Grand Prix in 1988; Murray drew a sketch of a three seater sports car and proposed it to Ron Dennis pitched as the idea of creating the ultimate road car a concept that would be heavily influenced by the Formula One experience and technology of the company and thus reflect that skill and knowledge through the McLaren F1. Quote from Gordon:[4] \"During this time we were able to visit with Ayrton Senna (the late F1 Champion) and Honda\'s Tochigi Research Center. The visit related to the fact that at the time McLaren\'s F1 Grand Prix cars were using Honda engines. Although it\'s true I had thought it would have been better to put a larger engine the moment I drove the Honda NSX all the benchmark cars—Ferrari Porsche Lamborghini—I had been using as references in the development of my car vanished from my mind. Of course the car we would create the McLaren F1 needed to be faster than the NSX but the NSX\'s ride quality and handling would become our new design target. Being a fan of Honda engines I later went to Honda\'s Tochigi Research Center on two occasions and requested that they consider building for the McLaren F1 a 4.5 liter V10 or V12. I asked I tried to persuade them but in the end could not convince them to do it and the McLaren F1 ended up equipped with a BMW engine.\" Later a pair of Ultima MK3 kit cars chassis numbers 12 and 13 \"Albert\" and \"Edward\" the last two MK3s were used as \"mules\" to test various components and concepts before the first cars were built. Number 12 was used to test the gearbox with a 7.4 litre Chevrolet V8 to mimic the torque of the BMW V12 plus various other components like the seats and the brakes. Number 13 was the test of the V12 plus exhaust and cooling system. When McLaren was done with the cars they destroyed both of them to keep away the specialist magazines and because they did not want the car to be associated with \"kit cars\". The car was first unveiled at a launch show 28 May 1991 at The Sporting Club in Monaco. The production version remained the same as the original prototype (XP1) except for the wing mirror which on the XP1 was mounted at the top of the A-pillar. This car was deemed not road legal as it had no indicators at the front; McLaren was forced to make changes on the car as a result (some cars including Ralph Lauren\'s were sent back to McLaren and fitted with the prototype mirrors). The original wing mirrors also incorporated a pair of indicators which other car manufacturers would adopt several years later. The car\'s safety levels were first proved when during a testing in Namibia in April 1993 a test driver wearing just shorts and t-shirt hit a rock and rolled the first prototype car several times. The driver managed to escape unscathed. Later in the year the second prototype (XP2) was especially built for crashtesting and passed with the front wheel arch untouched. [edit] Engine [edit] History The McLaren F1\'s engine compartment contains the mid-mounted BMW S70/2 engine and uses gold foil as a heat shield in the exhaust compartment. Gordon Murray insisted that the engine for this car be naturally aspirated to increase reliability and driver control. Turbochargers and superchargers increase power but they increase complexity and can decrease reliability as well as introducing an additional aspect of latency and loss of feedback the ability of the driver to maintain maximum control of the engine is thus decreased. Murray initially approached Honda for an NA powerplant with 550 bhp (410 kW; 560 PS) 600 mm (23.6 in) block length and a total weight of 250 kg (551 lb) it should be derived from the Formula 1 powerplant in the then-dominating McLaren/Honda cars. When Honda refused Isuzu then planning an entry into Formula 1 had a 3.5 V12 engine being tested in a Lotus chassis. The company was very interested in having the engine fitted into the F1. However the designers wanted an engine with a proven design and a racing pedigree. In the end BMW took an interest and the motorsport division BMW M headed by engine expert Paul Rosche[5] designed and built Murray a custom-designed 6.1 L (6064 cc) 60-degree V12 engine which was 14% more powerful than specified and 16 kg (35 lb) heavier – despite being based on the original specifications of 550 bhp (410 kW; 560 PS) 600 mm (23.6 in) block length and total weight of 250 kilograms (550 lb). [edit] Specifications The final result is a custom-built 6.1 L (6064 cc) 60-degree V12 with an aluminium alloy block and head 86 mm (3.4 in) x 87 mm (3.4 in) bore/stroke quad overhead camshafts for maximum flexibility of control over the four valves per cylinder and a chain drive for the camshafts for maximum reliability the engine is dry sump. At 266 kg (586 lb) the resulting engine was slightly heavier than Murray\'s original maximum specification weight of 250 kg (551 lb) but was also considerably more powerful than he had specified. The bespoke engineered engine for the F1 is called the BMW S70/2.[6] The carbon fibre body panels and monocoque required significant heat insulation in the engine compartment so Murray\'s solution was to line the engine bay with a highly efficient heat-reflector: gold foil. Approximately 25 g (0.8 ounce) of gold was used in each car.[7] The road version used a compression ratio of 10.5:1 to produce 627 brake horsepower (467 kW)[6] at 7400 rpm—considerably more than Murray\'s specification of 550 horsepower (404 kW). Torque output of 480 ft·lb (651 N·m) at 5600 rpm.[8] The engine has a red line and rev limiter set at 7500 rpm. Other more highly tuned incarnations of the F1 produced up to 691 bhp (515 kW; 701 PS) at 7500 rpm and 735 N·m (542 lb·ft) of torque (updated LM engine) making a significant performance improvement. There is only one other McLaren F1 roadcar with this engine.[citation needed] In contrast to raw engine power a car\'s power-to-weight ratio is a better method of quantifying performance than the peak output of the vehicle\'s powerplant. The standard F1 achieves 550 hp/ton (403 kW/tonne) or just 3.6 lb/hp. Compare with the Enzo Ferrari at 434 hp/ton (314 kW/tonne) (4.6 lb/hp) the SSC Ultimate Aero TT with 1003 hp/ton (747.9 kW/tonne) (2 lb/hp) and the Bugatti Veyron at 530.2 hp/ton (395 kW/tonne) (4.1 lb/hp). The cam carriers covers oil sump dry sump and housings for the camshaft control are made of magnesium castings. The intake control features twelve individual butterfly valves and the exhaust system has four Inconel catalysts with individual Lambda-Sound controls. The camshafts are continuously variable for increased performance using a system very closely based on BMW\'s VANOS variable timing system for the BMW M3;[9] it is a hydraulically-actuated phasing mechanism which retards the inlet cam relative to the exhaust cam at low revs which reduces the valve overlap and provides for increased idle stability and increased low-speed torque. At higher RPM the valve overlap is increased by computer control to 42 degrees (compare 25 degrees on the M3)[9] for increased airflow into the cylinders and thus increased performance. To allow the fuel to atomise fully the engine uses two Lucas injectors per cylinder with the first injector located close to the inlet valve – operating at low engine RPM – while the second is located higher up the inlet tract – operating at higher RPM. The dynamic transition between the two devices is controlled by the engine computer.[9] Each cylinder has its own miniature ignition coil. The closed-loop fuel injection is sequential. The engine has no knock sensor as the predicted combustion conditions would not cause this to be a problem. The pistons are forged in aluminium. From 1998 to 2000 the Le Mans–winning BMW V12 LMR sports car used a similar S70/2 engine. The engine was given a short development time causing the BMW design team to use only trusted technology from prior design and implementation experience. The engine does not use titanium valves or connecting rods. Variable intake geometry was considered but rejected on grounds of unnecessary complication.[9] Standard Mclaren F1 with all user accessible compartments opened. [edit] Chassis and body The McLaren F1 was the first production road car to use a complete carbon fibre reinforced plastic (CFRP) monocoque chassis structure.[10] Aluminium and magnesium was used for attachment points for the suspension system inserted directly into the CFRP.[11] The car features a central driving position – the driver\'s seat is located in the middle ahead of the fuel tank and ahead of the engine with a passenger seat slightly behind and on either side.[12] The doors on the vehicle move up and out when opened and are thus of the type butterfly doors. [edit] Aerodynamics The overall drag coefficient on the standard McLaren F1 is 0.32 [13] compared with 0.36 for the faster Bugatti Veyron and 0.357 for the current holder of the fastest car world record (as of 2008) – the SSC Ultimate Aero TT (in terms of top speed). The vehicle\'s frontal area is 1.79 and the total Cx is 0.57 respectively. Due to the fact that the machine features active aerodynamics[14][6][7] these are the figures presented in the most streamlined configuration. The normal McLaren F1 features no wings to produce downforce however the design of the underbody of the Mclaren F1 exploits ground effect to improve downforce which is increased through the use of two electric fans to further decrease the pressure under the car. A \"high downforce mode\" can be turned on and off by the driver. There is a small rear spoiler on the tail of the vehicle which is dynamic the device will adjust dynamically and automatically attempt to balance the center of gravity of the car under braking[7] – which will be shifted forward when the brakes are applied. The spoiler increases the overall drag coefficient from 0.32 to 0.39 and is activated at speeds equal to or above 40 MPH by brake line pressure.[9] [edit] Suspension Steve Randle who was the car\'s dynamicist was appointed responsible for the design of the suspension system of the McLaren F1 machine.[9] It was decided that the ride should be comfortable yet performance oriented however not as stiff and low as that of a true track machine as that would imply reduction in practical use and comfort as well as increasing noise and vibration which would be a contradictory design choice in relation to the former set premise – the goal of creating the ultimate road car. From scratch the design of the F1 vehicle had strong focus on centering the mass of the car as near the middle as possible by extensive manipulation of placement of i.a. the engine fuel and driver allowing for a low polar moment of inertia in yaw. The F1 has 42% of its weight at the front and 58% at the rear [9] this figure changes less than 1% with the fuel load. The distance between the mass centroid of the car and the suspension roll centre were designed to be the same front and rear to avoid unwanted weight transfer effects – allowing anti roll bars to be omitted. Computer controlled dynamic suspension were considered but not applied due to the inherent increase in weight increased complexity and loss of predictability of the vehicle. Damper and spring specifications: 90 mm (3.5 in) bump 80 mm (3.1 in) rebound with bounce frequency at 1.43 Hz at front and 1.80 Hz at the rear [9] despite being sports oriented these figures imply the rather soft ride and will inherently decrease track performance but again the Mclaren F1 is not in concept nor implementation a track machine. As can be seen from the Mclaren F1 LM Mclaren F1 GTR et al. the track performance potential is much higher than that in the stock F1 due to fact that car should be comfortable and usable in everyday conditions. The suspension is a double wishbone system with an interesting design i.a. that longitudinal wheel compliance is included without loss of wheel control which allows the wheel to travel backwards when it hits a bump – increasing the comfort of the ride. Castor wind-off at the front during braking is handled by Mclaren\'s proprietary Ground Plane Shear Centre – the wishbones on either side in the subframe are fixed in rigid plane bearings and connected to the body by four independent bushes which are 25 times more stiff radially than axially.[9] This solution provides for a castor wind-off measured to 1.02 degrees per G of braking deceleration. Compare the Honda NSX at 2.91 degrees per G the Porsche 928 S at 3.60 degrees per G and the Jaguar XJ6 at 4.30 degrees per G respectively. The difference in toe and camber values are also of very small under lateral force application. Inclined Shear Axis is used at the rear of the machine provides measurements of 0.04 degrees per G of change in toe-in under braking and 0.08 degrees per G of toe-out under traction.[9] When developing the suspension system the facility of electro-hydraulic kinematics and compliance at Anthony Best Dynamics was employed to measure the performance of the suspension on a Jaguar XL16 a Porsche 928S and a Honda NSX to use as references. Steering knuckles and the top wishbone/bell crank are also specially manufactured in an aluminium alloy. The wishbones are machined from a solid aluminium alloy with CNC machines.[9] [edit] Tyres The McLaren F1 uses 235/45ZR17 front tyres and 315/45ZR17 rear tyres.[6] These are specially designed and developed solely for the Mclaren F1 by Goodyear and Michelin. The tyres are mounted on 17x9 inches and 17x11.5 inches cast magnesium wheels protected by a tough protective paint. The five-spoke wheels are secured with magnesium retention pins.[12] The turning circle from curb to curb is 13 m (42.7 ft) or two turns from lock to lock. [edit] Brakes Gordon Murray attempted to utilize carbon brakes for the F1 but found the technology not mature enough at the time. The F1 features unassisted vented and crossdrilled brake discs made by Brembo. Front size is 332 mm (13.1 in) and at the rear 305 mm (12.0 in) [6][9] they are all four-pot opposed piston types made of aluminium.[9] The rear brake calipers does not feature any handbrake functionality however there is a mechanically actuated fist-type caliper which is computer controlled and thus serves as a handbrake. As carbon brakes have a more simplified application envelope in pure racing environments this allows for the racing edition of the machine the F1 GTR to feature ceramic carbon brakes.[5] To increase caliper stiffness the calipers are machined from one single solid (in contrast to the more common being bolted together from two halves). Pedal travel is slightly over one inch. Activation of the rear spoiler will allow the air pressure generated at the back of the vehicle to force air into the cooling ducts located at either end of the spoiler which become uncovered upon application of it. Servo assisted ABS brakes were ruled out as they would imply increased mass complexity and reduced brake feel; however at the cost of increasing the required skill of the driver. [edit] Gearbox and miscellaneous The standard McLaren F1 has a transverse 6-speed manual gearbox with an AP carbon triple-plate clutch[6] contained in an aluminium housing the second generation GTR edition has a magnesium housing [5] both the standard edition and the \'Mclaren F1 LM\' has the following gear ratios: 3.23:1 2.19:1 1.71:1 1.39:1 1.16:1 0.93:1 with a final drive of 2.37:1.[6] The gearbox is proprietary and developed by Mclaren.[5] The Torsen LSD (Limited Slip Differential) has a 40% lock.[6] The McLaren F1 has an extremely light and thin aluminium flywheel in order to decrease inertia and increase responsiveness of the system resulting in faster gear changes and better throttle feedback. [edit] Equipment Standard equipment on the stock McLaren F1 includes full cabin air conditioning a rarity on most sports cars and a system design which Murray again credited to the Honda NSX a car he had owned and driven himself for 7 years without according to the official F1 website ever needing to change the AC automatic setting. Further comfort features included SeKurit electric defrost/demist windscreen and side glass electric window lifts remote central locking Kenwood CD stereo system cabin access release for opening panels cabin stowage department four lamp high performance headlight system rear fog and reversing lights courtesy lights in all compartments map reading lights and a Facom titanium tool kit (stored in the car).[15] In addition tailored proprietary luggage bags specially designed to fit the vehicle\'s storage compartments including a tailored golf bag were standard equipment.[12] Airbags are not present in the car.[5] The driver\'s seat of the Mclaren F1 is custom fitted to the specifications desired by the customer for optimal fit and comfort; the seats are hand made from CFRP and covered in light Connolly leather.[12] By design the F1 steering column can not be adjusted however prior to production each customer specifies the exact preferred position of the steering wheel and thus the steering column is tailored by default to those owner settings. During its pre-production stage McLaren commissioned Kenwood to create a lightweight car audio system for the car; Kenwood between 1992 and 1998 used the F1 to promote its products in print advertisements calendars and brochure covers. Each car audio system was especially designed to tailor to an individual\'s listening taste however radio was omitted because Murray never listened to the radio. Every standard F1 also has a modem which allows customer care to remotely fetch information from the ECU of the car in order to help aid in the event of a failure of the vehicle.[16] [edit] Purchase and maintenance Up until 1998 when Mclaren produced and sold the standard F1 models they had a price tag of around 970 000 USD.[6] Today the cars can go up for nearly twice that of the original price due to the performance and exclusive nature of the machine. They are expected to further increase in value over time.[17] Although production has stopped in 1998 Mclaren still maintains an extensive support and service network for the F1. There are eight[17] authorized service centers throughout the world and McLaren can on occasion fly a specialized technician to the owner of the car or the service center. All of said technicians have undergone dedicated training in service of the McLaren F1. In cases where major structural damage has occurred the car can be returned to McLaren directly for repair.[17] On October 29th 2008 an F1 road car (chassis number 065) was sold at an RM Automobiles of London auction for $3.68 Million USD. This was the car from the McLaren showroom on Park Lane London. With only 484 kilometers on its odometer this pristine example set a world record for the highest price ever paid for an F1 road car.[18] [edit] Performance In terms of sheer top speed the F1 remains as of 2008 one of the fastest production cars ever made; as of July 2008 it is only succeeded by the Koenigsegg CCR [19] the Bugatti Veyron[20] and the SSC Ultimate Aero TT.[21] However all of the superior top speed machines exploit forced induction to reach their respective top speeds – making the Mclaren F1 the fastest naturally aspirated production car in the world (as of November 2008). [edit] Acceleration * 0-30 mph (48 km/h): 1.7 s[citation needed] * 0–60 mph (97 km/h): 3.2 s[6] * 0–100 mph (160 km/h): 6.7 s[6] * 0–124.28 mph (200.01 km/h): 9.4 s[22] * 1/4 mile: 11.6 s[6] [edit] Top speed * With rev limiter on: 231 mph (372 km/h) * With rev limiter removed: 243 mph (391 km/h) See subsection on Record claims below for additional information citations and discussion. [edit] Cornering * When performing the lateral acceleration exercise around a 200 ft (61 m) skidpad (for testing some aspects of cornering performance) the standard F1 machine performs 0.86 G; compare 0.99 G for the Saleen S7 1.01 G for the Ferrari Enzo and 1.15 G for the Koenigsegg CC (all post year 2000 vehicles).[13][23] * For the slalom exercise the standard F1 can perform at 64.5 miles per hour (103.8 km/h).[23] [edit] Braking * As for the 60-0 mph brake exercise the standard Mclaren F1 can come to a standstill in 127 ft (39 m) after 2.8 seconds compare 125 ft (38 m) for the Saleen S7 109 ft (33 m) for the Ferrari Enzo and 105 ft (32 m) for the Koenigsegg CC (all post year 2000 vehicles).[13] [edit] Track tests * Tsukuba Circuit time trial: 1:04.62 on a hot lap.[22] * Bedford Autodrome West Circuit time trial: 1:21.20 on a hot lap which is faster than the Ferrari Enzo at 1:21.30.[22] * Millbrook Proving Ground in Bedfordshire 2-mile (3.2 km) banked circuit top speed test: An average speed of 195.3 mph (314.3 km/h) with a maximum speed of 200.8 mph (323.2 km/h) (driven by Tiff Needell using the XP5 prototype).[24] * MIRA 2.82-mile (4.54 km) banked circuit top speed test: An average speed of 168 mph (270 km/h) with a maximum speed of 196.2 mph (315.8 km/h) (driven by Peter Taylor).[24] [edit] Record claims The title of \"world\'s fastest production road car\" is constantly in contention especially because the term \"production car\" is not well-defined. The McLaren F1 has a top speed of 231 mph (372 km/h) [25] restricted by the rev limiter at 7500 rpm. The true top speed of the Mclaren F1 was reached in April of 1998 by the five-year-old XP5 prototype. Andy Wallace (racer) piloted it down the 9 km straight at Volkswagen’s Ehra test track in Wolfsburg Germany setting a new world record of 243 mph (391 km/h) at 7800 rpm. As Mario Andretti noted in a comparison test the F1 is fully capable of pulling a seventh gear thus with a higher gear ratio or a seventh gear the Mclaren F1 would probably be able to reach an even greater top speed (something which can also be observed by noticing that the top speed was reached at 7800 rpm while the peak power is reached at 7400 RPM). [edit] Variants Total Production Variant Road Prototype Race Total F1s 64 5 69 F1 LMs 5 1 6 F1 GTs 2 1 3 F1 GTR 28 28 Total 71 7 28 106 The McLaren F1 road car of which 64 were originally sold saw several different modifications over its production span which were badged as different models. Of the road versions 21 are reportedly in the United States. One of the completed street cars remained in McLaren\'s London showroom for a decade before being offered for sale as new in 2004. This vehicle became the 65th McLaren F1 sold. The showroom which was on London\'s luxurious Park Lane has since closed. The company maintains a database to match up prospective sellers and buyers of the cars. According to an article by Motor Authority the Sultan of Brunei owns a total of 9 McLaren F1s. This includes a GTR race car a GT \"longtail \" 3 LMs and 4 road cars making him the only person in the world to own at least one of every variant of the F1 ever produced by McLaren.[26] [edit] Prototypes Prior to the sale of the first McLaren F1s five prototypes were built all carrying the numbers XP1 through XP5.[25] These cars carried minor subtle differences between each other as well as between the production road cars. XP1 was the first publicly unveiled car and later destroyed in the accident in Namibia. XP2 was used for crash testing and also destroyed. Neither were ever painted. XP3 did durability testing XP4 stress tested the gearbox system and XP5 was a publicity car all owned by McLaren; they were also used for publicity shots and tested by reporters.[25] All were painted a different colour and each was able to be distinguished by their chassis code painted on the side rocker panel. XP4 was seen by many viewers of Top Gear when reviewed by Tiff Needell in the mid 1990s while XP5 went on to be used in McLaren\'s famous top speed run.

The car also had a different transaxle various aerodynamic modifications specially-designed 18-inch (457 mm) magnesium alloy wheels and upgraded gearbox. The F1 LM also used the same engine as the 1995 F1 GTR however without race-mandated restrictors to produce (680 bhp/500 kW). It had a top speed of 225 mph (362 km/h) which is less than the standard version due to added aerodynamic drag despite identical gear ratios. The LM is 76 kg (168 lb) lighter than the stock F1 – a total mass of 1 062 kg (2 341 lb) – this is achieved through i.a. no interior noise suppression no audio system a very stripped down base interior no fan assisted ground effect and no dynamic rear wing. In the place of the small dynamic rear wing there is a considerably larger fixed CFRP rear wing mounted on the back of the vehicle. The fact that the idle noise level inside the car is loud enough to prevent verbal communication is the reason that the car comes with a headset which features ear protection and a means of communication through microphone for the occupants.[citation needed] The LM machine has the following performance figures: a peak torque of 705.0 nm (520.0 ft·lbf) at 4500 rpm and a peak power of (680 bhp/500 kW) at 7800 rpm it has a redline at 8500 rpm the total weight of 1 062 kg (2 341 lb) gives the car a 110.16 bhp (82 kW; 112 PS) per litre ratio.[28] The F1 LM is regarded to be the fastest incarnation of the McLaren F1 roadcars through the gears and in overall track performance.[who?] It has a 0-60 mph (97 km/h) time of 2.9 seconds [29] 0-100 mph (161 km/h) in 5.9 seconds[29] and was once the holder of many world records including the 0-100-0 mph record which it completed in 11.5 seconds when driven by Andy Wallace at the disused airbase RAF Alconbury in Cambridgeshire.[29][30] The F1 LMs can be identified by their Papaya orange paint. The F1 LM\'s were painted in this colour in memory and tribute to Bruce McLaren whose race colour was Papaya orange. Although only five F1 LMs were sold a sixth chassis exists in the form of XP1 LM the prototype for modifications to the existing F1 to form the new F1 LM. This car is also painted Papaya Orange and is retained by McLaren. This car reportedly worth $4 million has been promised by McLaren CEO Ron Dennis to his driver Lewis Hamilton if he should win an additional two Formula One World Championship titles.[31] [edit] F1 GT The final incarnation of the roadcar the F1 GT was meant as a homologation special. With increased competition from homologated sports cars from Porsche and Mercedes-Benz in the former BPR Global GT Series and new FIA GT Championship McLaren required extensive modification to the F1 GTR in order to remain competitive. These modifications were so vast that McLaren would be required to build a production road-legal car on which to base the new race cars. The F1 GT featured the same extended rear bodywork as the GTRs for increased downforce and reduced drag yet lacked the rear wing that had been seen on the F1 LM.[32] The downforce generated by the longer tail was found to be sufficient to not require the wing. The front end was also similar to the racing car with extra louvers and the wheel fenders widened to fit larger wheels. The interior was modified and a racing steering wheel was included in place of the standard unit. The F1 GTs were built from standard F1 road car chassis retaining their production numbers. The prototype GT known as XPGT was F1 chassis #056 and is still kept by McLaren. The company technically only needed to build one car and did not even have to sell it. However demand from customers drove McLaren to build two production versions that were sold. The customer F1 GTs were chassis #054 and #058. [edit] Motorsports Main article: McLaren F1 GTR Following its initial launch as a road car motorsports teams convinced McLaren to build racing versions of the F1 to compete in international series. Three different versions of the race car were developed from 1995 to 1997. Many F1 GTRs after the cars were no longer eligible in international racing series were converted to street use. By adding mufflers passenger seats adjusting the suspension for more ground clearance for public streets and removing the air restrictors the cars were able to be registered for road use. [edit] F1 GTR \'95 A 1995-spec F1 GTR which has been modified for street use. A 1997-spec F1 GTR \"Long Tail\" during an FIA GT Championship event. Built at the request of race teams such as those owned by Ray Bellm and Thomas Bscher in order to compete in the BPR Global GT Series the McLaren F1 GTR was a custom built race car which introduced a modified engine management system that increased power output — however air-restrictors mandated by racing regulations reduced the power back to 600 hp (447 kW). The cars extensive modifications included changes to body panels suspension aerodynamics and the interior. The F1 GTR would go on to take its greatest achievement with 1st 3rd 4th 5th and 13th places in the 1995 24 Hours of Le Mans beating out custom built prototype sports cars. In total nine F1 GTRs would be built for 1995. [edit] F1 GTR \'96 To follow up on the success of the F1 GTR into 1996 McLaren further developed the \'95 model leading to a size increase but weight decrease. Nine more F1 GTRs were built to 1996 spec while some 1995 cars were still campaigned by privateers. F1 GTR \'96 chassis #14R is notable as being the first non-Japanese car to win a race in the All-Japan Grand Touring Car Championship (JGTC). The car was driven by David Brabham and John Nielsen. [edit] F1 GTR \'97 With the F1 GT homologated McLaren could now develop the F1 GTR for the 1997 season. Weight was further reduced and a sequential transaxle was added. The engine was slightly destroked to 6.0L instead of the previous 6.1L. Due to the heavily modified bodywork the F1 GTR \'97 is often referred to as the \"Longtail\" thanks to the rear bodywork being extended to increase rear downforce. A total of ten F1 GTR \'97s were built. [edit] Replicas and Models 1:87th and 1:43rd models by Minichamps/PMA. Kit car builder DDR Motorsport builds a kit that resembles the F1 based on the Toyota MR-2 SW20 Turbo. Certain die-cast scale models of the F1 are now extremely desirable among collectors. Most of these models are now out of production. Manufacturers of McLaren F1 models include UT Models Maisto Minichamps/Paul\'s Model Art Guiloy and Autobarn. Models have been produced in 1:87 1:64 1:43 1:24 1:18 and 1:12. Among the most desirable of these models are the Minichamps 1:43 McLaren F1 GTR West Promotion model (which can sell for 1 000 dollars). And the UT Models 1:18 silver & dark blue McLaren F1 LMs (which each can sell for over US$400 at auction).
