Ford GT40s went on to win at Le Mans even after the withdrawal of factory support, in 1968 and 1969, but Alan Mann Racing set its sights on an entirely new competition class, developing the aerodynamically-efficient, aluminum-monocoque Ford P68 (a.k.a. “Ford 3L GT”) to race in the top-tier prototype category. It was the Ford F3L or P68, painted red and gold in the Alan Mann racing colours, and at once all was reality, everyone in the racing game was there, the tail was opened up and presented to us was an all-Ford racing project, sponsored by Ford of Britain, designed by Len Bailey and built in the Alan Mann workshops at Byfleet.

TheFord G68, also commonly known as théFord 3L GTorN3L, is definitely a sports prototyperacing vehicle model released in Mar 1968. It has been developed by Len BaiIey, a Ford study engineer, funded by Ford Europe and constructed by Alan Mann Racing at Weybridge, Surréy, UK. The initial competition look of a Fórd 3L prototype was at the BOAC 500 race at Brand names Hatch in Kent. Despite apparent pace, the car was criticized for lack of stability at higher speeds and, owing to mechanised and electric failures, do not finish any of the events for which it had been joined.
For the 1969 time of year the P68 was utilized as the time frame for an aborted, completely open up Spyder, dubbed theFord G69. The G69 sported large, free-standing aerofoilwings, which had been vital to the car's balance at high-speeds. Nevertheless, these were banned by the European sanctioning entire body earlier in the period, hence the P68 was not qualified to competition in the particular class any much longer.
Backgroundédit
At thé end of the 1967 time of year the FIA redrew the guidelines for sports activities car racing. Engine capacity was limited to 3 litres for the lightest, most advanced Group 6 sports activities prototype course, while a brand-new 5 litre Group 4 Sports Car course1was introduced for vehicles of which at least 50 good examples had happen to be built. Ford's United states headquarters company withdrew from sports activities car race at the finish of 1967,2leaving behind those groups dedicated to running the growing old GT40 without factory support. While some groups, like as JWA, chose to move down the Group 4 Sports Car route and began work on updating the GT40, Alan Mann Racing made a decision to construct a brand name new prototype vehicle around Ford't recently introduced 3.0L DFVV8Method One engine.
Raising sponsorship from Ford, as nicely as Burmah-CastroI and Goodyéar, AMR procured the solutions of leading Ford aerodynamicistLen Bailey, who got designed significantly of the GT40's bodywork, to function on their fresh car.
Style edit
Thé car was constructed to Team 6 rules, with an open two-seat bodywork style. This was perhaps instead liberally viewed, with just a little hatch in the in any other case enveloping roofing being left open up to the components.3The hatch also allowed the drivers to discover the centrally mounted rear-view hand mirror.
One major advantage of the open prototype regulations was that they permitted a much lower roofline than in any other case would have got been possible. Bailey utilized this to develop an incredibly low, lengthy, curvaceous, aerodynamically effective design. With a Gdof only 0.272and a frontal region of 14 feet²3the 3.0L engine was adequate to push the P68 to over 350 kilometres/h,2faster than contemporary Formulation One vehicles. However, former driver Frank Gardner has criticised Bailey't search of aerodynamic effectiveness at the expenditure of motorist ease and comfort.4In order to keep the P68 on the street, Bailey incorporated a trademarked, vortex-generating tail scoop, meant to generate downforce without incorporating to move. Nevertheless, although the car provides since ended up demonstrated to produce moderate downforce at swiftness, this will be mostly over the front side tires.2The resultant high-speed instability directed to both John Surtees and Jack Brabham refusing to drive the vehicle.25Over the using a few months the P68 sprouted actually larger back spoilers, and little face spoilers, in an effort to stabilise the car.
Undérneath the curvaceous bódywork, the chassis has been a riveted, aIuminiummonocoque, with steelbulkheads ónto which the suspension components were mounted.3The DFV engine was backed in an aluminum cradle behind the car owner. Unlike the Lótus 49 for which the DFV had been developed, the engine was not used as a structural framework member. In comparison, the suspension layout has been nearly a direct copy of modern N1 exercise. Modern observers mentioned on the oversized front hub components, potentially enabling the vehicle to end up being converted to four-wheel drive at some point.3The radiator has been installed in the nose, although afterwards enhancements to air conditioning lead in a wider starting being included from mid-season. Gasoline was saved in two deformable cells, one in éach siIl.
Right after poor results, during the wintertime of 1968 Len Bailey adapted the P68's monocoque to fully exploit the open-roof rules. A fully open spyder prototype was produced with nearly completely fresh bodywork panels; also lower and wider, it also included a dramatic decrease in duration.5Mechanicals were carried more than from the P68 in nearly unchanged form. This brand-new car has been numbered the P69, although variations with the G68 had been only skin strong. In an try to remedy the exact same stability complications that afflicted the G68, the P69 had an innovative program of interconnected, hydraulically-controlled, partially automatic, flexible aerofoilwings.5However, following many mishaps with related systems during Formulation One competitions, the wings had been swiftly banned by the FIA early in the period. Without wings, AMR evaluated that the vehicle would require a comprehensive redesign to become aggressive with the prominent Porsches and consequently, lacking money, the P68/P69 task was abandoned.
Race history edit
A Fórd P68 on screen at the Goodwood Celebration of Velocity.
The very first set of vehicles was ready for the Western european season-opening BOAC 500 competition, at Brands Hatch on 7 April 1968. Actually this earlier in its profession, the P68 got began to grow spoilers and air flow dams at its top and rear. Two cars were got into, for Bruce McLarén and Denny HuIme, and Jochén Rindt and Mike Spence.6Nevertheless, the two vehicles were relatively untested, with one in fact being brand brand-new, and teething problems beset the weekend. Although originally decrease during practice, continuous tuning and tweaking supposed that by the finish of qualifying McLaren had maintained to place in a panel fast more than enough to consider second location on the grid, dividing the works Porsche 907s. Unfortunately, the Rindt/Spence vehicle had suffered an engine mount failure and neglected to meet the criteria. Spence, something of a Manufacturers Hatch professional, was substituted into the business lead car for the competition, and had been at the wheel, leading the competition, when a rubber restaurant in the transmission failed, placing the car out. Although neither car had finished, the pace and performance while operating looked to be promising better for the potential future.
This promise was never to end up being achieved. With Paul Spence'h loss of life during practice for the 1968 Indiana 500, fellow Brit Chris Irwin was selected in for the G68's next race: the 1968 1000km Nürburgring. He was lucky to get away loss of life when he dropped handle of his vehicle at the Flugplatz during practice, although his injuries were severe sufficiently for his profession to end up being finished. The vehicle was ruined.7In the competition, once again the remaining P68 was unable to finish owing to mechanised gremlins. This had been to end up being the pattern during all the remaining competitions for which the G68 has been entered during 1968. One tantalising highlight occurred when Frank Gardner, who performed very much of the P68's restricted developmental tests, took rod place at the 1000kmichael Spa race. However, as soon as once again the car flattered to trick, as it stuttéred to a stop on the first lap of the race with faulty eIectrics. By this time the G68's faults had been all too apparent, and Alan Mann Race decided not to vacation to the Zeltweg race.

Fór 1969 AMR designed to change the G68 with its aunt car, the P69. Nevertheless, by the period of the 1969 BOAC 500 competition only one P69 has been ready. After attempting the G69, prior to being approved, Jack port Brabham flatly declined to drive the car in frustration so volatile did he discover it. That remaining just a year-old P68 to bring the AMR flag, in the fingers of Hulme ánd Gardner. A Iarge, high-mounted side was connected straight to the covers of the back suspension podiums, which proceeded to go some method to decreasing rear-end lift at acceleration, but once again an motor failure ended the vehicle before the end of the race. The final competition outing for the Fórd 3L prototype had been at the AM0C Martini Trophy conference at Silverstone. But car owner Gardner by no means even made the grid, as rainfall during practice soaked the vehicles electrics, making it unable to begin.
