Competition history
The Bristol 450 made its race debut at the 1953 24 Hours of Le Mans race. Two cars were entered, with a third held back as a spare. Unfortunately for Bristol, both were out before half distance with near-identical failures. In each case the balance weights became detached from the crankshaft. This caused the rear wheels to lock at high speed, in turn causing the cars to veer off the road and catch fire. However, in the laps that the cars had managed to complete, Jack Fairman easily managed to post a new lap record for the 2 litre class.[3] The cars were rebuilt at the factory, incorporating the revised aerodynamic bodywork, and only three weeks later, in early July, were entered into the 12h race at Reims. The Reims track shared the high speed character of its French cousin at La Sarthe and suited the Bristol's character well. Although one car again broke down, this time due to transmission failure on the first lap, the remaining car cruised to a class victory and finished fifth overall.[6]
The cars returned to France in early October for a series of reliability speed record attempts at the Montlhéry circuit. All were successful, and on 6 October 1953 the Bristol team set six records for the 2-litre class, for endurance over a variety of distances and times: 200 miles (125.87 mph); 500 km (116.10 mph); 500 miles (112.25 mph); 1,000 km (115.49 mph); 3 hr (116.42 mph); and 5 hr (115.43 mph).[7]
The cars did not race again until the 1954 Le Mans race. This time three cars were entered, with uprated engines and the improved aerodynamic bodywork. In contrast with the previous year, and despite torrential rain, all three cars finished the race, coming home in first, second and third in their class and seventh, eighth and ninth overall.[8] Their performance also earned Bristol the team prize.[3] The 450s remained in France for the Reims race, and again demonstrated unblemished reliability, taking 2nd, 3rd and 4th in class, beaten only narrowly by a Ferrari for the class victory.[9]
Once again, Bristol was only interested in high-speed endurance racing and so the cars were put into storage until the 1955 24 Hours of Le Mans. With the revised, open bodywork the cars repeated their dominance of the previous year. Again they finished seventhth, eighth and ninth overall, first, second and third in class, and took the team prize.[10] The lead car averaged over 100 mi/h for more than the first 12 hours—only slowing on team orders—and spent only fifteen minutes in the pits during the entire 24 hour race.[3]
However, despite this dominant victory record, the tragic accident during the race and a corporate shift away from emphasis on their products' sporting credentials persuaded Bristol to withdraw from racing immediately following their 1955 Le Mans triumph. Their prize monies were quietly donated to the relief fund for victims of the disaster, and they withdrew from the 1955 Reims race.[3] Rather than allow poorly financed and inexperienced privateer teams to run their cars in inappropriate events, on their return to the factory the best car was selected, built up using the best components from all chassis, and the remainder scrapped. This car was retained by Bristol Cars owner and former racing driver Tony Crook for the next 30 years,[5] on occasion loaning its engine to one of Crook's road-going saloons. In the late 1990s it was fully restored to 1955 specifications, and currently makes infrequent appearances at historic race meetings.
