At HWM Works, we specialise in Aston Martin engine rebuilds, performance upgrades and bespoke engine builds for modern Aston Martin road and race cars. As the world’s longest-serving Aston Martin dealer, our engineering team combines decades of Aston Martin expertise with meticulous in-house craftsmanship to create engines of exceptional quality, reliability and performance.
Every engine is completely stripped, inspected, precision measured and rebuilt to exacting standards using motorsport-informed processes and blueprinting techniques. Whether you require a standard Aston Martin engine rebuild, a performance upgrade, or a complete bespoke specification, HWM Works delivers a level of engineering and attention to detail beyond conventional remanufacturing.
We regularly work on engines fitted to the following Aston Martin models:
Aston Martin DB7, Aston Martin Vantage, Aston Martin DB9, Aston Martin DBS, Aston Martin V12 Vantage, Aston Martin Rapide, Aston Martin Vanquish, Aston Martin Vanquish S, Aston Martin Vantage GT12, Aston Martin Virage, Aston Martin DBS Superleggera and Aston Martin DBX, alongside specialist motorsport applications.
From naturally aspirated V8, V12 engines, pressure-charged engines, through to race-derived performance builds - every project is completed entirely in-house under uncompromising engineering standards.
As an official Aston Martin dealership, HWM can also supply factory Aston Martin re-manufactured engines. However, we strongly believe that a carefully engineered rebuild offers significant advantages over replacement.
Each engine is meticulously balanced, measured and assembled to deliver exceptional drivability, refinement, and durability. Our blueprinting process ensures every critical tolerance is optimised, resulting in engines that consistently exceed original factory feel and performance.
Unlike a conventional replacement engine, a rebuild also allows us to tailor the engine to your exact requirements, whether your priority is improved road response, enhanced torque delivery, increased top-end performance, or long-term reliability.
