The DBR1 was a purpose-built sports-racing prototype designed by Ted Cutting for the World Sportscar Championship, built to the new 1956 rules that no longer required road-based cars. Multi-tubular spaceframe; front torsion-bar and trailing-arm suspension; De Dion rear with longitudinal torsion bars and Watt linkage; all-aluminium twin-cam straight-six, originally 2,493 cc (to early rules) and from 1958 enlarged to 2,992 cc producing around 268 bhp; David Brown CG537 five-speed transaxle; approximately 801 kg. Five examples built between 1956 and 1959.
After a retirement on its single-car 1956 Le Mans debut, the DBR1 won the Nürburgring 1000 km in 1957, 1958 and 1959 (a hat-trick, mostly Stirling Moss), and delivered Aston Martin's only outright 24 Hours of Le Mans victory in 1959 (DBR1/2, Carroll Shelby and Roy Salvadori), with DBR1/4 second. That year Aston Martin won the World Sportscar Championship — one of only three cars in the 1950s to take both Le Mans and the championship in one season. Its six WSC victories were a 1950s record.
The most important competition Aston Martin and one of the most valuable British cars in existence.
