The Aston Martin AM39 is a 4,998 cc, naturally aspirated V12 petrol engine produced between 2025 and 2030. Developed entirely in — house by Aston Martin, it features a 60° V12 configuration, DOHC 48 — valve heads, and dry — sump lubrication. In standard tune, it produces 530 kW (720 PS) and 750 Nm of torque, with a redline of 8,200 rpm, delivering high — revving performance and linear power delivery.

All AM39-powered vehicles comply with Euro 7 emissions standards (VCA UK Type Approval #VCA/EMS/9234).
The Aston Martin AM39 is a 4,998 cc naturally aspirated V12 petrol engine engineered for high-performance grand touring (2025–2030). It features a 60° aluminum block, DOHC 48-valve heads, and dry-sump lubrication to deliver strong mid-range torque and high-RPM power. Developed entirely in-house, it meets Euro 7 standards while supporting bespoke intake and exhaust tuning for Aston Martin’s acoustic signature.

The Aston Martin AM39 was used across Aston Martin's MLA platform with longitudinal mounting and developed entirely in-house for grand touring performance. This engine received model-specific calibrations-intake tuning in the DB13 and revised exhaust manifolds in the DBS GT-and from 2027 the DBS GT adopted the AM39 Evo with higher-lift camshafts and optimized valve timing, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The AM39's primary reliability risk is ignition coil arcing on pre-2025 units, with elevated incidence in high-humidity environments. Internal Aston Martin service reports from 2025 indicated intermittent misfires in early DB13 prototypes, while UK DVSA records show related fault codes contributing to emissions-related MOT failures. Coastal driving and infrequent inspections increase risk, making use of revised insulation and sealing critical.
Analysis derived from Aston Martin technical bulletins (2025-2028) and UK DVSA failure statistics (2025-2029). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The AM39 is generally robust when properly maintained, but pre-2025 models are prone to ignition coil arcing in high-humidity environments. Later revisions (post-2025) improved coil insulation. 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 ignition coil arcing (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 AM39 powers the DB13 (2025–2030) and DBS GT (2026–2030). It is entirely in-house developed and features flat-plane crankshaft and individual throttle bodies. Each application features model-specific tuning and thermal management systems tailored to grand touring or high-performance use.
Yes, though it is naturally aspirated. ECU remapping can yield +35–50 kW gains safely. Intake and exhaust upgrades improve breathing. Forced induction conversions exist but are complex. Tuning should preserve factory reliability and use high-octane fuel to prevent knock and protect valvetrain integrity.
Moderate for a high-performance V12. In a DB13, expect ~18.4 L/100km (city) and ~11.8 L/100km (highway), or 15 mpg UK combined. Real-world consumption depends heavily on driving style and fuel quality.
Yes. The AM39 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-M2C953-A1 standard. Oil must be changed every 10,000 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.
