[[Aston Martin]] has produced a number of [[V12 engine|V12]] [[Petrol engine|petrol engines]] for its models. The first version appeared in 1999, when a 5.9-litre, 60° V12 debuted in the [[Aston Martin DB7]] Vantage.
==Overview== The original Aston Martin "AML V12" project began in 1994, at [[Ford Motor Company|Ford]]'s Advanced Powertrain division. As Aston Martin was owned by Ford at the time, this gave Aston Martin access to Ford's considerable engineering and technology resources.
The design goal was to build a unique V12 for Aston Martin, while leveraging many of Ford's best resources. The engine would be designed to compete at the Le Mans 24 Hours, deliver very high torque from low RPM as well as high-revving power, would be scalable for power growth well beyond a "normal duty" Ford engine, and would only use a component from other Ford projects if it made sense and did not compromise the design.<ref name="origins1">{{Cite web|url=https://www.designjudges.com/articles/the-origins-of-aston-martins-v12/|title=THE ORIGINS OF ASTON MARTIN'S V12|access-date=23 June 2023}}</ref><ref name="origins2">{{Cite web|url=https://www.classicmobilia.com/news/the-heart-of-aston-martin-motor-cars/|title=The heart of Aston Martin Motor cars|access-date=23 June 2023}}</ref><ref name="origins3">{{Cite web|url=https://www.hotcars.com/aston-martins-v12-engine-humble-origins/|title=Here's Why The Aston Martin's V12 Engine Became Legendary From Humble Origins|access-date=23 June 2023}}</ref>
The AML V12 design featured all-new block, cylinder head and crankshaft designs, using the piston assemblies and valvetrain components from the then-upcoming [[Ford_Duratec_V6_engine|Ford Duratec V6]] family. The use of some Duratec components may have contributed to the myth of the AML V12 being "two Duratec V6s welded together". The reality is that the engines are quite different. The Duratec V6 is A319 cast aluminium with cast-in iron liners and bed-plate bottom end. The AML V12 is A365-T6 aluminium, features a deep-skirt six-bolt main block, thin-wall press-in liners and directly mounts nearly all of its drive accessories. It features 3.0mm-larger main bearings, a bank-to-bank offset approximately 15mm less than the V6, and has a completely different casting design including a precision water jacket. The cylinder heads differ as well. The Duratec V6s are A319 cast aluminium, the AML V12s are A365-T6 cast aluminium with unique combustion chambers, a higher compression ratio, a precision water jacket and unique intake ports (one of the design features that significantly improved low-end torque while maintaining high-end power).<ref name="origins1"/><ref name="origins2"/><ref name="origins3"/>
The AML V12 ran for the first time in September 1995. The first engine completed was taken by Ford to be shown in the [[Ford_Indigo|Indigo]] concept supercar. This version was unique in that it was dry-sumped, unlike the later production versions, and fitted with a Ford V12 nameplate. Engine number 2 was installed in a DB7, which was the intended platform for the engine.<ref>{{Cite web|url=https://www.designjudges.com/articles/the-indigo-story|title=THE INDIGO STORY|access-date=23 June 2023}}</ref>
The first time the public got to see the AML V12 with proper Aston Martin badging was in "Project Vantage", the prototype of the first-generation Vanquish shown at NAIAS in January 1998, a year before the 1999 Geneva Motor Show reveal of the DB7 Vantage. The DB7 Vantage became the first production model to feature the AML V12.<ref name="origins1"/><ref name="origins2"/><ref name="origins3"/>
Ford and Aston Martin partnered with [[Cosworth]] Technology to manufacture the AML V12s, until Aston Martin's {{cvt|12500|m2|sqft}} [[Aston Martin Engine Plant|dedicated engine plant]] within the [[Ford Germany]] plant in [[Niehl, Cologne]] became operational in 2004.<ref>{{cite web |url=https://www.autocar.co.uk/car-news/industry/aston-martin-opens-new-engine-plant |title=Aston Martin opens new engine plant |website=Autocar |date=29 October 2004}}</ref><ref>{{cite web |url=https://astonmartins.com/factory-guide/aston-martin-engine-plant-amep/ |title=Aston Martin Engine Plant (AMEP) |website=astonmartins.com |date=29 October 2004}}</ref><ref>{{cite web |url=https://astonmartins.com/db9-production-at-am-gaydon-20034/ |title=DB9 Production at Gaydon |website=astonmartins.com |date=29 October 2004}}</ref>
The AML V12 has evolved over the years, with a number of power, torque, [[fuel efficiency]], and emissions upgrades. In 2016, the design was significantly modified, with a reduction in displacement to 5.2 litres, and the addition of twin turbos. This engine made its debut in the [[Aston Martin DB11]].<ref>{{cite web|url=https://www.roadandtrack.com/new-cars/car-technology/news/a29656/aston-martins-new-twin-turbo-v12s-are-off-the-line/|title=Aston Martin Has Started Building its New Twin-Turbo V12s|first=Mate|last=Petrany|website=Road & Track|date=22 June 2016|access-date=22 June 2016}}</ref><ref>{{cite web|url=https://www.caranddriver.com/news/a15348786/aston-martin-details-its-new-twin-turbo-v-12-hear-it-roar/|title=Aston Martin Details Its New, Twin-Turbo V-12—Hear It Roar|first=Mike|last=Duff|website=Car and Driver|date=4 May 2016|access-date=4 May 2016}}</ref><ref>{{cite web|url=https://www.autocar.co.uk/car-news/new-cars/aston-martin-db11-first-all-new-v12-engine-built|title=Aston Martin DB11: first all-new V12 engine built|first=Julian|last=Rendell|website=Autocar|date=21 June 2016|access-date=21 June 2016}}</ref><ref>{{cite web|url=https://www.autoevolution.com/news/aston-martin-s-second-generation-v12-engine-under-inspection-150680.html|title=Aston Martin's Second-Generation V12 Engine Under Inspection|first=Vlad|last=Radu|website=Autoevolution|date=27 October 2020|access-date=27 October 2020}}</ref> In 2024, the engine received multiple enhancements for the third-generation [[Aston Martin Vanquish#Third generation (2024–present)|Aston Martin Vanquish]],<ref>{{cite web|url=https://www.autoexpress.co.uk/aston-martin/vanquish|title=New Aston Martin Vanquish unveiled with roaring 823bhp V12|first=Jordan|last=Katsianis|website=Auto Express|date=3 September 2024|access-date=3 September 2024}}</ref><ref>{{cite web|url=https://www.evo.co.uk/aston-martin/vanquish/207109/the-new-aston-martin-vanquish-is-an-824bhp-ps333k-ferrari-12cilindri|title=The new Aston Martin Vanquish is an 824bhp, £333k Ferrari 12Cilindri rival|first=Yousuf|last=Ashraf|website=Evo|date=3 September 2024|access-date=3 September 2024}}</ref> including a new, stronger block to cope with the extra output, larger turbochargers that spin 15% faster and at up to 15% higher compression, new camshafts, new cylinder heads and new intake runners.<ref>{{cite web|url=https://www.autocar.co.uk/car-news/new-cars/aston-martin-vanquish-returns-824bhp-v12-flagship|title=Aston Martin Vanquish returns as 824bhp V12 flagship|first=Will|last=Rimell|website=Autocar|date=2 September 2024|access-date=2 September 2024}}</ref><ref>{{cite web|url=https://www.carmagazine.co.uk/car-news/first-official-pictures/aston-martin/vanquish/|title=Return of the Vanquish – Aston Martin's new V12 super GT revealed|first=Jake|last=Groves|website=CAR Magazine|date=2 September 2024|access-date=2 September 2024}}</ref><ref>{{cite web|url=https://www.caranddriver.com/news/a61946878/2025-aston-martin-vanquish-revealed/|title=Aston Martin Vanquish Returns as the Brand's GT King|first=Joe|last=Lorio|website=Car and Driver|date=2 September 2024|access-date=2 September 2024}}</ref><ref>{{cite web|url=https://www.motortrend.com/news/2025-aston-martin-vanquish-v12-first-look-review/|title=2025 Aston Martin Vanquish First Look: New V-12 GT Gunning for Ferrari|first=Angus|last=MacKenzie|website=Motor Trend|date=2 September 2024|access-date=2 September 2024}}</ref>
