In 1959, one year after the DB4's debut, Aston Martin launched their competition version, the DB4GT.
Changes from the standard DB4 were primarily weight and power, weight was saved with a wheelbase reduction of just over 12 cm and power was increased to 302 bhp, by fitting a twin-plug head, and triple 45DCOE twin choke Weber carburettors to the all-alloy 3670 cc straight six engine.
As on the standard DB4 the Touring designed body was constructed on the 'Superleggera' principle, body panels fixed on a very strong lightweight tubular frame, but the 16 gauge aluminium panels of the DB4 were replaced by 18 gauge magnesium alloy panels. Visually distinguishable features of the GT were the large bonnet air scoop and the cowled front lights.
The DB4 GT prototype made an impressive competition debut in the hands of Stirling Moss in the International Trophy meeting at Silverstone, taking a class victory and for the remainder of the season the DB4 GT proved as fast as the Ferrari 250 GT.
Although intended as a competition car, many of the 74 DB4 GTs constructed were used as road cars. The end of DB4 GT production in 1963 meant the end of the Aston Martin’s factory competition effort, the 4 Project cars excepted, although many of the DB4 GTs are still regularly used in a wide variety of events.
