Background
The Jaguar D Type had a particularly tough act to follow.
Its C Type predecessor had won Le Mans at its first outing in 1951 and then again in 1953.
The following year, Jaguar went back to the drawing board for their next potential Le Mans winning car, the D Type.
Jaguar Chief Engineer and Technical Director, William Heynes, teamed up with ex-Bristol Aeroplane Company aerodynamicist, Malcolm Sayer.
Out went the C Type’s tubular chassis and in came an aluminium monocoque tub, a uprated engine 3.4 straight-6 engine offering 250bhp, and an aerodynamic fin specifically developed to give the car more stability on the long, fast Mulsanne Straight.
In 1954, however, the winner’s laurels at Le Mans were claimed by a Ferrari 375 Plus, with the D Types plagued by various fuel filter, brake and engine problems.
The first D Type victory came in the Reims 12-hour race in July 1954.
For the 1955 season, factory cars were fitted with a longer nose, lengthening the car by 7½ inches.
The headrest fairing and the distinctly shark-like aerodynamic fin were combined into a single unit for maximum slipperiness and minimum weight.
These changes further increased potential maximum speed to something in the region of 190mph.
The D Type’s legendary status was earned at Le Mans, with three successive victories in 1955 (Hawtorn/Bueb, XKD 505), 1956 (Flockhart/Sanderson, Ecurie Ecosse, XKD 501) and 1957 (Flockhart/Bueb, Ecurie Ecosse, XKD 606).
The first of these victories, in 1955, was perhaps the most bittersweet in the history of motorsport.
The 1955 race had developed into a contest between the ‘Golden Boy’, Mike Hawthorn, and Mercedes’ Juan Manuel Fangio. The Argentinian legend is still regarded by many as probably the greatest racing driver who has ever lived.
Hawthorn, who could be charming, entertaining, snobbish and boorish in equal measure, was considered even at the time to be a driver whose undoubted talent was occasionally compromised by a gung-ho desire to win at all costs – particularly in the context of his fierce rivalry with Mercedes.
On lap 35, while pulling further ahead of his rival Fangio, Hawthorn cut across Lance Macklin in order to make a pit-stop.
Macklin braked and swerved, forcing the following Pierre Levegh to hit Macklin’s car.
Levegh just had time to wave a warning to Fangio before his car somersaulted through the air and disintegrated, killing him instantly.
The engine, now ripped free of the car, had the momentum to fly through the crowded grandstand at around head height for more than 100 metres.
At least 83 people died and several hundred were injured in what remains motorsport’s worst ever disaster.
Some blamed Hawthorn. Some blamed Macklin.
Everybody blamed the woefully inadequate safety measures in place and, consequently, all future Le Mans races benefitted from improved safety provisions for drivers and spectators alike.
Mercedes withdrew from motorsport completely and didn’t return until 1994, and then only as an engine supplier to the Sauber F1 team.
In the ’57 race, when the more powerful 3.8 litre D Types were supreme in their ascendancy, they finished 1st, 2nd, 3rd, 4th and 6th.
The racing car in which Hawthorn and Bueb won their hollow victory at the 1955 Le Mans 24 heures was one of only 75 D Types ever built.
It is numbered XKD 505.
The D Type we have for you today was built as an homage to XKD 505 and, although it is not a toolroom replica, it is both cosmetically and mechanically an impressively faithful recreation of that iconic car in most respects.
