After an announcement on 27 September, 1969, the DBS was made available with the long awaited V8 engine, with the car being known as the DBSV8 – a four-seat grand touring car, capable of 160 mph. As with the straight six, the design of the new V8 engine was the work of Tadek Marek. With a capacity of 5340cc and 4 overhead camshafts with Bosch mechanical fuel injection, the DBSV8 was the fastest 4 seater production car in the world at the time. This engine was to form the basis of all Aston Martin power plants for the next 20 years.
Apart from the change of engine, notable visual differences were the specially designed 15’’ GKN light alloy wheels (as opposed to the distinctive wire wheels employed on the DBS), with ventilated brake discs for the first time on an Aston Martin production car. A Chrysler Toqueflite auto transmission was offered as an alternative to the ZF manual 5 speed unit.
In common with the 6 cylinder DBS, the DBSV8 was produced until May 1972, after which the car adopted the later single headlamp front end. New owner, Company Developments Ltd, renamed the car AM V8.
