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. The engine features individual throttle bodies per cylinder and a flat-plane crankshaft for optimal exhaust scavenging and F1-inspired responsiveness.
Fitted to the DB13 and upcoming DBS GT, the AM39 was engineered for grand touring refinement and dynamic responsiveness. Its integration into Aston Martin’s MLA platform includes tuned engine mounts and acoustic management for cabin refinement. Emissions compliance is achieved through gasoline particulate filters (GPF), direct fuel injection, and advanced ECU mapping, allowing the engine to meet Euro 7 standards across all markets.
One documented update is the transition from Bosch MD17.9.1 to Bosch MD17.9.3 ECU in late 2027, improving torque delivery and cold-start emissions (Aston Martin Engineering Bulletin AM39-27-006). Additionally, early DB13 prototypes exhibited intermittent ignition coil arcing under high humidity. From 2025, revised coil insulation and sealing per Service Information Bulletin AM39-SIB-25-008 were implemented to enhance electrical reliability.
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 naturally aspirated AM39 provides linear throttle response ideal for grand touring, but demands strict adherence to 10,000 km oil change intervals using Mobil 1 FS 0W-40 (WSS-M2C953-A1) to maintain dry-sump system integrity and chain longevity. The flat-plane crankshaft enhances exhaust note and high-RPM power but increases vibration, necessitating precise engine mounting. Early models (pre-2025) may experience ignition coil arcing in high-humidity environments; verify insulation and sealing per SIB AM39-SIB-25-008 if misfires occur. Fuel quality is critical—premium unleaded (RON 98) is required to prevent knock and preserve performance. Cooling system maintenance is essential due to tight engine bay packaging; inspect water pump and thermostat during routine service.
Oil Specs: Requires Mobil 1 FS 0W-40 meeting Aston Martin WSS-M2C953-A1 (Aston Martin SIB AM39-25-005). Formulated for high-pressure valve train and dry-sump systems.
Emissions: All AM39 engines comply with Euro 7 (VCA Type Approval #VCA/EMS/9234), verified through RDE and WLTP testing protocols.
Power Ratings: Measured under SAE J1349 standards. 530 kW output requires RON 98 fuel and precise ignition mapping (Aston Martin TIS Doc. AM39-ECU-021).

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.
Locate the engine serial number stamped on the right-hand side of the engine block near the rear mounting flange (Aston Martin TIS AM39-ID-001). The 7th VIN digit indicates engine type ('3' for AM39 series). All units have black cam covers with 'AM39' and 'Aston Martin' badging. Critical differentiation from Mercedes-AMG M279: AM39 features in-house flat-plane crankshaft, individual throttle bodies, and unique ECU calibration. Service parts require model-year verification—ignition coils for pre-2025 DB13 models are incompatible with post-2025 units due to insulation upgrade per SIB AM39-SIB-25-008.
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.
