The Lola Mk6 GT was a racing car with a production run of only three units, built between 1962 and 1963 by British car manufacturer Lola Cars. With its 289 cubic inch Ford V8 engine, the Mk6 GT was the first mid-mounted, high displacement V8-powered Grand Touring car, a chassis arrangement that had been used, up until that time, only on formula cars and smaller, more affordable GTs.
Development
Mid-engined cars were a revolutionary idea introduced in motor racing by the Cooper Car Company, a small British firm that managed to beat big players in the Formula 1 World Championship two years in a row. This engine layout did not make its way into Grand Tourers, which were accepted to race only if a minimum production run had been completed: not a single manufacturer was keen on making a big investment to build cars "at a minimum rate of one hundred identical units as far as mechanical parts and coachwork are concerned in 12 consecutive months", as required by the FIA, without having the necessary experience with such applications and the right components. It is important to note that in those days there was no commonly available transaxle gearbox capable of managing the enormous torque provided by big V8 engines. When the Colotti Tipo 37 gearbox was made available to the market after being specifically built to be mounted on the Lotus 29single seater, a racing car powered by a Ford Fairlane V8 and intended to race in the 1963 Indianapolis 500, Lola's owner Eric Broadley had the opportunity to solve the problem. Moreover, the FIA's decision to terminate its World Sports Car Championship and replace it with the new International Championship for GT Manufacturers for the 1962 season, in order to focus manufacturers' attention on Grand Tourers, made it more difficult for mid-engined GT cars to make their way into production. But the Federation left an open door to research and development, admitting to races Experimental Grand Touring cars, with no minimum production requirement, but requiring roadworthiness. The Lola Mk6 GT was conceived by Eric Broadley at the end of 1962 to be accepted into the Experimental Grand Touring class.
Technical description
The Mk6 GT featured some of the best technology of the time: first of all an aluminium monocoque, while all opponents, apart from Jaguar, still relied on a space frame chassis. The Ford-Colotti engine-gearbox assembly was a stressed member and the rear suspension was mounted directly on it, a technique that did not appear in full on Formula 1 cars until the Lotus 49 in 1967. As a result the car was so compact that the wheelbase was even shorter than Lola's other formula cars, despite using a big pushrod 400 hp American V8 engine. The coachwork, designed by John Frayling and made by FRP, had its own features such as reduced overhangs, Kamm-tail, roof-integrated engine air intake and special doors which extended into the roof to give the drivers greater access to the cockpit once they were open, an idea that was kept on the car's successor, the Ford GT40.
Racing history
The prototype car was shown to the public in January 1963 at the UK Olympia Racing Car Show, making a big success and provoking great expectations, and during the following months South African Tony Maggs raced it at Silverstone and at the Nürburgring 1000 km, while the second car was being completed and prepared for the 1963 24 Hours of Le Mans. Short of preparation time, Broadley himself brought LGT-1 to Le Mans at the very last moment for technical verifications, which required some modifications to the car. After their completion the car was allowed to race, but the time spent couldn't be used for proper testing: the car raced with the wrong gear ratios, was not able to show all of its potential and was forced to retire after 15 hours following an accident due to a gear selector failure. Understanding the potential performance of the Mk6, the Ford Motor Company bought it so as to further test its capabilities, laying the foundation for its GT40 project and involving Broadley himself, although he later left the program. Meanwhile, a third car, the second aluminium monocoque not raced at Le Mans that year because it was not ready, was completed and sold to the American Mecom Racing Team who raced it at Brands Hatch, where the Ford engine broke after only four laps. Replaced by a Traco-tuned 6 litre Chevrolet V8 delivering 530 hp at 6500 rpm, the car was extensively raced in North America and won the 1963 Bahamas Speed Week
