Aston Martin has made a number of mechanically similar V8 engines over the years, since the first one used in the Aston Martin V8 in 1969.^[1][2] They have been both naturally-aspirated and supercharged.

The 1969–1972 Aston Martin DBS V8 coupe/convertible was Aston Martin's first V8 model. This engine was an all-aluminium construction with double overhead camshafts and was used in several models up until 2000 when the Virage model was discontinued.

Production of V8-engined Aston Martin cars resumed in 2005 with a new generation of the Vantage, powered by the Jaguar AJ-V8 naturally aspirated V8 engine.^[3][4][5][6] Since 2016, Aston Martin has switched to the Mercedes-Benz M177 turbocharged V8 engine, beginning with the DB11 model.^[7][8]
