The Aston Martin AM28 is a 3,982 cc, V8 petrol engine produced between 2016 and 2020. It is a clean — sheet design developed entirely in — house by Aston Martin, marking a departure from previous Ford/Jaguar — based architectures. Featuring twin overhead camshafts (DOHC), 32 — valve configuration, and variable valve timing, it delivers high — revving performance with linear power delivery. In standard tune, it produced 375 kW (510 PS) and 610 Nm of torque, later increased to…
All AM28-powered vehicles meet Euro 6b emissions standards .
The Aston Martin AM28 is a 3,982 cc V8 petrol engine engineered for high-performance grand touring and sports car applications (2016–2020). It features a lightweight aluminum block, DOHC 32-valve heads, and dual injection (direct + port) to deliver strong mid-range torque and high-RPM power. Designed in-house and manufactured at Aston Martin’s facility in Cologne, Germany, it meets Euro 6b standards while supporting dry-sump lubrication for track use.

The Aston Martin AM28 was used across Aston Martin's VH platform vehicles with longitudinal mounting and entirely in-house design. This engine received model-specific calibrations-intake tuning in the Vantage and revised exhaust manifolds in the DB11 V8-and from 2019 the Vantage AMR adopted the AM28-HP variant with higher-lift camshafts and optimized valve timing, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The AM28 is generally robust when properly maintained, but pre-2019 models are prone to crankshaft sensor signal issues. Later revisions (post-2019) improved harness shielding. Regular oil changes with correct 0W-40 specification and coolant system maintenance are essential. Well-serviced engines can exceed 120,000 km without major issues.
The most frequent issues are crankshaft sensor signal instability (especially pre-2019), oil consumption in high-mileage engines, cooling system leaks, and throttle body motor wear. These are documented in Aston Martin service bulletins and supported by dealer repair records.
The AM28 powered the DB11 V8 (2016–2020) and the Vantage (2018–2020), including the Vantage AMR. It was developed in-house and is not shared with any other manufacturer. Each application features model-specific tuning and intake systems.
Aftermarket ECU tuning is common on the AM28 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Moderate for a high-performance V8. In a DB11 V8, expect ~15.2 L/100km (city) and ~9.1 L/100km (highway), or 19 mpg UK combined. The lighter Vantage achieves slightly better economy. Real-world consumption depends heavily on driving style and fuel quality.
Yes. The AM28 is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, causing catastrophic damage. Chain replacement is recommended every 120,000 km or 10 years, whichever comes first.
Aston Martin specifies Mobil 1 0W-40 meeting WSS-M2C949-A1 standard. Oil must be changed every 12,000 km or 1 year. Using incorrect oil can accelerate cam and chain wear due to the dry-sump system and high-pressure valve train design.
