Aston Martin DB3 1951

The Aston Martin 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 for 1952. The car went on to place 2nd, 3rd, and 4th at Silverstone that year behind a Jaguar C-Type. The cars were forced out of Le Mans, but did claim the 9-hour race at Goodwood. The Aston Martin DB3S was a lighter version of the car, introduced in 1953. It was somewhat more successful, and was produced until 1956. Two coupe versions were also built.
