Background

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]
