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.{{cite news |url= http://www.autocar.co.uk/car-news/new-cars/aston-martin-confirms-new-52-litre-v12-twin-turbocharged-engine |title=Aston Martin confirms new 5.2-litre V12 twin-turbocharged engine |work=Autocar |first=Matt |last=Burt |date=11 January 2016 |access-date=12 March 2016}}{{cite web |url=https://www.astonmartin.com/en/media-centre/company/engine-plant |title=Aston Martin Engine Plant |publisher=Aston Martin |access-date=12 March 2016}}{{cite news |url= http://www.motorauthority.com/news/1085010_has-aston-martin-just-extended-its-engine-deal-with-ford |title=Has Aston Martin Just Extended Its Engine Deal With Ford? |first=Viknesh |last=Vijayenthiran |work=Motor Authority |date=25 June 2013 |access-date=12 March 2016}}{{cite news |url=http://www.autocar.co.uk/car-news/industry/aston-martin-signs-new-ford-engine-deal-report |title=Aston Martin signs new Ford engine deal |work=Autocar |date=24 June 2013 |access-date=12 March 2016}} Since 2016, Aston Martin has switched to the Mercedes-Benz M177 turbocharged V8 engine, beginning with the DB11 model.{{cite news|url=http://www.thedrive.com/new-cars/19214/new-aston-martin-vantage-borrows-v-8-sugar-from-mercedes-amgs-gt-so-which-tastes-sweeter|title=The New Aston Martin Vantage Borrows Some V-8 Sugar from Mercedes-AMG's GT...So Which Tastes Sweeter?|last=Ulrich|first=Lawrence|work=The Drive|access-date=11 July 2018|language=en-US}}{{cite web|url=https://newatlas.com/aston-martin-db11-v8-amg-engine/50243/|title=DB11 becomes the first Aston Martin with a Mercedes-AMG heart|website=newatlas.com|date=28 June 2017|language=en|access-date=11 July 2018}}
