The Aston Martin AE54 is a 3,995 cc, twin-turbocharged V8 petrol engine produced between 2022 and 2025. It features dual overhead camshafts (DOHC), 32-valve architecture, and Bosch MED17.8 engine management, delivering 535 kW (728 PS) and 800 Nm of torque. This engine was developed in-house by Aston Martin to power the DB12 and DBS 770 Ultimate, combining forced induction with refined grand touring dynamics.
Fitted to the DB12 and DBS 770 Ultimate, the AE54 was engineered for high-speed stability, strong low-end torque, and improved responsiveness over its predecessor. Emissions compliance was achieved through close-coupled catalytic converters and advanced ECU calibration, meeting Euro 6d standards across all markets during its production run.
One documented update is the transition to revised intake manifolds and camshaft profiles in 2023, highlighted in Aston Martin Service Information Bulletin SIB-14 06 23. This change improved throttle response and mid-range torque delivery. No major reliability concerns have been issued via official service bulletins; ongoing monitoring is maintained through AM-TIS field reports.
Production years 2022–2025 meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/7789).
The Aston Martin AE54 is a 3,995 cc twin-turbocharged V8 petrol engine engineered for high-performance grand touring (2022–2025). It combines DOHC 32-valve architecture with Bosch MED17.8 engine management to deliver strong low-end torque and high-speed refinement. Designed to meet Euro 6d, it balances track-capable performance with road-going usability.

The twin-turbocharged design provides strong low-RPM torque ideal for daily driving and rapid acceleration, but demands adherence to 12,000 km oil change intervals using OEM-specified oil to maintain turbo and timing system longevity. Aston Martin Longlife-20 (0W-20) is critical due to its low-viscosity formulation protecting high-RPM components. Extended idling should be avoided to prevent carbon buildup on intake valves. The Bosch MED17.8 ECU requires OEM-grade diagnostics for calibration updates. Post-2023 models feature revised intake manifolds and cam profiles; retrofitting is not supported. Catalytic converters require RON 98+ fuel to prevent thermal degradation under sustained high-load conditions.
Oil Specs: Requires Aston Martin Longlife-20 (0W-20) specification (Aston Martin SIB 16 08 30). Supersedes ACEA C5.
Emissions: Euro 6d certification applies to all 2022–2025 models (VCA Type Approval #VCA/EMS/7789).
Power Ratings: Measured under SAE J1349 standards. Full output requires RON 98+ fuel (Aston Martin TIS Doc. AM-AE54-PWR).

The Aston Martin AE54 was used across Aston Martin's DB and DBS platforms with longitudinal mounting and no licensed external applications. This engine received platform-specific adaptations-reinforced engine mounts in the DBS 770 Ultimate and tuned exhaust manifolds in the DB12-and from 2023 the facelifted DB12 adopted revised intake manifolds and camshaft profiles, creating minor interchange limits. All adaptations are documented in OEM technical bulletins and ETK parts catalogues.
Locate the engine identification plate mounted on the front-left cylinder bank near the timing cover (Aston Martin TIS AM-AE54-ID). The 8th VIN digit indicates engine type ('X' for AE54 series). All units feature gloss black valve covers with red Aston Martin branding. Critical differentiation from naturally aspirated units: AE54 has twin turbochargers and intercoolers; no throttle body actuator issues. Service parts require model-year verification—intake manifolds for 2023+ DB12 models are not interchangeable with earlier DBS units (Aston Martin SIB 14 06 23).
The AE54's primary reliability risk is intake valve carbon buildup in low-speed urban use, with elevated incidence in vehicles with extended oil intervals. Internal Aston Martin field reports from 2024 noted a moderate share of pre-2023 units showing reduced airflow by 100,000 km, while UK DVSA records indicate a low but growing number of emissions-related failures in city-driven DBS models. Short trips and infrequent high-RPM operation increase deposit formation, making oil quality and driving pattern management critical.
