The DBS replaced the DB6 in 1967 as Aston Martin's four-seat grand tourer, moving away from Touring's superleggera construction to a steel platform-and-panel body styled in-house by William Towns. It was engineered from the outset to accept the new Tadek Marek 5.3-litre V8, but delays meant early cars used the familiar 4.0-litre twin-cam straight-six from the DB6 Vantage.
The DBS V8 arrived in September 1969 with Bosch mechanical fuel injection and transformed the car's performance. In 1972 the six-cylinder DBS was renamed Aston Martin Vantage and the DBS V8 became simply Aston Martin V8, ending the DBS designation. The car is best known today as James Bond's Aston in On Her Majesty's Secret Service (1969) and Diamonds Are Forever (1971).
The DBS is the transition point between the Touring-era DB cars and the long-running V8 that followed. It carries the launch of the Marek V8 and the last of the six-cylinder DB engine — and remains materially cheaper than the DB6 that preceded it.
