The Aston Martin DB3 and later DB3S were racing cars built in the 1950s. Although they used some DB2 parts, they were quite different, being designed especially for racing. The original modifications were done by ex-Auto Union engineer, Eberan von Eberhorst, though others handled the later DB3S work.

DB3

The DB3 was introduced in 1951 with a 133 hp (99 kW) 2.6 L Lagonda straight-6 engine from the DB2 Vantage. The car was unsuccessful, so a larger 2.9 L engine, producing 163 hp (122 kW), was introduced in June 1952. The car was placed 2nd, 3rd, and 4th at Silverstone May 1952 (in 2.6 ltr form) that year behind a Jaguar C-Type. The cars were forced out of Le Mans, but did claim the 9-hour race at Goodwood.

Chassis numbers

In total 10 DB3's were made between 1951 and 1953, with chassis numbers from DB3/1 to DB3/10. Cars 1 to 5 being used as works cars and cars 6 to 10 being sold as customer cars.

Coupé's

Several Aston Martin DB3's have received coupé style bodies over the years. Pictured left is Aston Martin DB3/7 Coupé at Silverstone Classic 2008

 

DB3S

The DB3S was a lighter version of the car, introduced in 1953. It was somewhat more successful, and was produced until 1956.

Originally two 'works' coupe versions were also built.

The DB3S was replaced in 1956 by the famed DBR1, which finally claimed Le Mans in 1959.
