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 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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The S63B44 offers exceptional performance and refinement, but requires meticulous maintenance. Early models (2016–2017) had HPFP issues, and all variants are sensitive to oil neglect. With strict adherence to service intervals and use of high-octane fuel, these engines can achieve 150,000 km reliability. Regular inspections and proactive part replacement are essential for longevity.
Key issues include high-pressure fuel pump wear, timing chain tensioner wear, turbocharger wastegate actuator sticking, and intake vacuum leaks. These are documented in Aston Martin service bulletins. Preventive maintenance—especially timely HPFP inspection and oil changes—significantly reduces risk of major repairs.
The S63B44 powers the DB11 AMR (2016–2020), Vantage AMR (2018–2020), and DBS Superleggera (2018–2020). It is longitudinally mounted and tuned for high-performance grand touring. No cross-manufacturer applications are documented. This engine was derived from BMW's S63 platform and adapted for Aston Martin's performance ethos.
Yes. The S63B44 responds well to ECU remapping, with stage 1 tunes typically adding +50–70 kW. Upgraded intercoolers, exhausts, and fuel systems allow higher gains. Tuning must preserve boost and thermal management limits to avoid reliability issues. Specialist tuners offer bespoke packages for DBS and Vantage AMR applications.
In combined driving, expect ~15.8 L/100km (17.9 mpg UK). Highway cruising can achieve ~11.0 L/100km (25.7 mpg UK), while city driving may exceed 19 L/100km (15.0 mpg UK). Real-world consumption depends heavily on driving style, fuel quality, and vehicle condition.
Yes. The S63B44 is an interference engine. If the timing chain fails, piston-to-valve contact will cause catastrophic internal damage. Regular inspection and replacement of the timing chains at 120,000 km or 8 years is critical to prevent costly engine rebuilds.
Aston Martin specifies M-spec 0W-20 synthetic oil. Change intervals are 15,000 km or annually. Using correct oil ensures proper turbo, chain, and VVT system lubrication, reducing wear and maintaining performance. Extended drain intervals risk turbo bearing failure and chain slippage.
