Very much an interim model, the Two-Litre Sports was launched in 1948, not long after Aston Martin had been acquired by David Brown.

The Two-Litre Sports was soon retitled to become the Aston Martin DB1.

The DB prefix was attached to all of the cars developed by Aston Martin during the David Brown era, which ran from 1947 till the early Seventies.

Aston Martin utilised the new multi-tube frame and high-output four-cylinder engine designed by Claude Hill, a talented engineer of that time, who had been commissioned to design the engine before Brown took over.

It was never intended that the DB1 would go into any form of scheduled production, as it was hand-built at almost every stage and was very far from being cost-effective.

The chassis frame was derived from pre-war Aston Martin prototype known as the Atom, constructed in a semi-modular fashion from slim square-section tubes and was extensively cross-braced.

This feature, along with the DB1's coil spring front suspension, and rear axle located by coil springs and radius arms, was the signature for a whole new type of Aston Martin.

On the other hand, the DB1’s engine, a pushrod Overhead Valve 2-litre was no more than a relic of the pre-war era that would not be used on any future model.

The Aston Martin DB1’s design was reasonably typical of open-topped touring cars available immediately after the end of World war Two, with a bulky, four-seater drophead coupe body style, with the car’s spare wheel mounted in a pocket in the front wing.

Although the car was far from being a commercial success, the design and development team at Aston Martin learned a lot from the DB1.

Particular engineering elements of the chassis frame, as well as the styling theme of the nose, would be seen again on the car’s successor, the DB2.

In motoring history, it is now widely recognised that Aston Martin used the DB1 2-liter Sports as a testbed for so many of the models that followed it.

Just 14 DB1s were produced, eventually causing the model to become a real rarity, and a desirable collector's item as a result.
