History of the Aston Martin DB3S
After the DB3 failed to be competitive, William Watson, employed as Eberhorst’s assistant, presented an alternative design to John Wyer, Aston Martin’s competitions manager. The DB3S was introduced in 1953 and proved significantly more successful than the DB3.

Racing, 1953–1958
Although the DB3S failed at Le Mans in 1953, the cars scored a 1–2 at the Tourist Trophy at Dundrod, the sixth round of the first World Sportscar Championship, helping Aston Martin to third in the championship, and won the non-championship Goodwood 9 Hours. 1954 was less successful, with a third place in the Buenos Aires 1000 km the high point.
1955 saw a return to form: Collins and Frère finished second at Le Mans and Walker and Poore were fourth at the Tourist Trophy, which put Aston Martin fifth in the championship, with another win at the Goodwood 9 Hours. By 1956 the design was ageing and resources went into the DBR1, but the DB3S was still fourth at Sebring and fifth at the Nürburgring 1000 km, and Moss and Collins took another second at Le Mans, which that year was a non-championship event. The last swan song was the Whitehead brothers’ second place at Le Mans in 1958, after all the works DBR1s failed to finish. The car won the 2013 Gran Turismo Trophy at the Pebble Beach Concours d’Elegance.
Coupés
Two works DB3S fixed-head coupés were made to be more aerodynamic than the open cars, but they were unstable at high speed and both crashed at the 1954 24 Hours of Le Mans. They were rebuilt as open cars. Three customer cars were also fitted with similar coupé bodies.
