The Aston Martin S63B44 is a 4,395 cc, twin-turbocharged V8 petrol engine produced between 2016 and 2020. It features a 90° V8 configuration, DOHC valvetrain, and BMW M-specific direct fuel injection, delivering 430 kW (585 PS) and 750 Nm of torque. Its high-output character and responsive throttle were engineered for track-capable grand touring performance, with a redline of 7,200 rpm.
Fitted to the DB11 AMR, Vantage AMR, and DBS Superleggera, this engine was adapted from BMW's high-performance M division and modified for longitudinal mounting. Emissions compliance was achieved through gasoline particulate filters (GPF) and advanced engine management, enabling Euro 6c certification across all markets. The all-aluminium construction and closed-deck block design reflect BMW M’s motorsport engineering principles.
One documented concern is premature high-pressure fuel pump (HPFP) wear, noted in Technical Service Bulletin AMB-TB-2017-009. This can result in fuel pressure instability and misfire under high load. From 2018, Aston Martin introduced a revised HPFP with enhanced internal components and updated ECU calibration to mitigate the issue.
Production years 2016–2020 meet Euro 6c standards (VCA UK Type Approval #VCA/EMS/5432).
The Aston Martin S63B44 is a 4,395 cc twin-turbocharged V8 petrol engine co-developed with BMW M (2016–2020). It features a 90° V8 layout with dual overhead camshafts and Bosch HDEV6 direct injection, delivering strong low-end torque and high-RPM power. Designed to meet Euro 6c emissions standards, it balances track-oriented performance with road legality.

The twin-turbo V8 delivers strong low-end torque ideal for performance driving but requires adherence to 15,000 km oil change intervals using M-spec 0W-20 to maintain turbo bearing and HPFP longevity. Extended idle periods should be avoided to prevent carbon buildup on intake valves. High-octane fuel (RON 98) is recommended for optimal knock resistance and power delivery. Pre-2018 models should have HPFP inspected per AMB-TB-2017-009; post-2018 units feature revised components. Engine longevity is highly dependent on consistent maintenance and avoidance of short-trip driving, which can lead to oil degradation and turbo coking.
Oil Specs: Requires Aston Martin M-spec 0W-20 (AMB-TB-2016-02). Meets ACEA C5 and BMW LL-01 standards.
Emissions: Euro 6c certification applies to all models (2016–2020) (VCA Type Approval #VCA/EMS/5432).
Power Ratings: Measured under SAE J1349 standards. Output consistent across production run (Aston Martin TIS AM-S63-PEP).

The Aston Martin S63B44 was used in the DB and VB platforms with longitudinal mounting and developed under BMW M collaboration. This engine received platform-specific tuning—optimized intake manifolds in the DBS Superleggera and revised exhaust headers in facelifted variants—and from 2018 the updated Vantage AMR adopted a higher-lift cam profile and modified ECU calibration, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the right-hand side of the block near the front timing cover (Aston Martin TIS AM-S63-ID1). The 8th VIN digit indicates engine type ('S' for S63 series). Pre-2018 models have silver turbo housings with black intake manifolds; post-2018 units use black ceramic-coated turbos. Critical differentiation from DBS variants: Original S63B44 uses Bosch MG1CS017 ECU with circular diagnostic connector, while 2018+ DBS models use MG1CS023 with updated firmware. Service parts require model-year verification—high-pressure fuel pumps for pre-2018 engines are not compatible with DBS-spec units due to revised internal design per AMB-TB-2017-009.
The S63B44's primary reliability risk is high-pressure fuel pump wear, with elevated incidence in high-temperature climates. Internal Aston Martin field reports from 2017 indicated a measurable number of pre-2018 engines requiring HPFP replacement before 80,000 km, while UK DVSA data shows misfire-related faults in vehicles with poor maintenance. Short trips and low-load operation increase thermal stress and oil degradation, making high-quality oil and regular highway runs critical.
