The Aston Martin DB4 GT was a special lightweight, high-performance version of the DB4. Introduced in September, 1959, the GT's featured enclosed headlights and a thinner aluminum skin for lighter weight. The wheelbase was also reduced in comparison to the standard car, which resulted in many cars not being fitted with rear seats.

The engine, though, was what made the GT special. Available in 3.7 L and 3.8 L versions, the GT's engine had twin sparkplugs per cylinder with two distributors and three twin-choke Weber carbs. Modifications to the cylinder head brought compression to 9.0:1 and power output was 302 hp . Maximum speed for the GT was 153 mph with a 6.1 second sprint to 60 mph.

75 GTs were built with this body style, in addition to the separate DB4GT Zagato model.

This particular DB4GT was prepared for the Nassau Speed Weeks by the factory and was sent along with another DB4GT for Sir Stirling Moss. The original Moss entered car received extensive damage during the event and so Moss switched to this car. He won a five lap qualifying race and was leading the feature event until a loose nut was sucked through the carburettors, resulting in a bent valve.

This car was restored by the Aston Martin factory to orginal racing trim and Moss has been reunited with it at the Nassau Speed Weeks reunion as well as the Goodwood Festival of Speed.
