The Aston Martin AE18 is a 4,500 cc twin-turbocharged V8 petrol engine engineered for high-performance grand touring and luxury applications (2025–2030). It features a 90° aluminum block, DOHC 32-valve heads, and hot-V turbocharging to deliver rapid torque delivery and responsive power. Developed entirely in-house, it meets Euro 7 standards while supporting 48V mild-hybrid integration and advanced thermal management.

The Aston Martin AE18 was used across Aston Martin's MLA platform with longitudinal mounting and developed entirely in-house for hybrid performance. This engine received model-specific calibrations-intake tuning in the Vantage and revised exhaust manifolds in the DB13-and from 2027 the Lagonda adopted the AE18-Hybrid variant with enhanced ISG output and revised thermal management, 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 AE18 is generally robust when properly maintained, but pre-2025 models are prone to electric water pump failures. Later revisions (post-2025) improved pump design and control logic. Regular oil changes with correct 0W-40 specification and cooling system maintenance are essential. Well-serviced engines can exceed 120,000 km without major issues.
The most frequent issues are electric water pump failure (especially in early DB13), 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 AE18 powers the DB13 (2025–2030), next-generation Vantage (2025–2030), and Lagonda (2026–2030). It is entirely in-house developed and features 48V mild-hybrid integration. Each application features model-specific tuning and thermal management systems tailored to grand touring or luxury use.
Aftermarket ECU tuning is common on the AE18 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 twin-turbo V8 with hybrid assist. In a DB13, expect ~16.2 L/100km (city) and ~10.1 L/100km (highway), or 17 mpg UK combined. The Lagonda achieves slightly better economy due to hybrid boost. Real-world consumption depends heavily on driving style and fuel quality.
Yes. The AE18 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 FS 0W-40 meeting WSS-M2C952-A1 standard. Oil must be changed every 10,000 km or 1 year. Using incorrect oil can accelerate turbo bearing and chain wear due to the high-temperature, high-pressure environment of the twin-turbo V8 with mild-hybrid assist.
