The Aston Martin B6 5.2L is a 5,204 cc, twin-turbocharged V12 petrol engine produced between 2019 and 2023. Developed in-house, it represents the pinnacle of Aston Martin’s naturally aspirated V12 evolution, featuring DOHC, 48-valve architecture and high-pressure direct fuel injection. Delivering up to 535 kW (725 PS) and 700 Nm of torque, it enables hyper GT performance with a focus on acoustic quality and linear power delivery.
Fitted exclusively to the DBS Superleggera and DBS GT Zagato, the B6 5.2L was engineered for extreme grand touring and limited-series exclusivity. Its compact twin-scroll turbo layout prioritizes throttle response and high-rpm refinement, with dry-sump lubrication ensuring consistent oil pressure under high-G cornering. Emissions compliance is achieved through integrated exhaust manifolds and secondary air injection, meeting Euro 6d standards.
One documented concern is high-pressure fuel pump (HPFP) degradation under sustained high-load operation, highlighted in Aston Martin Technical Service Bulletin TSB-ENG-023. This issue correlates with fuel quality and extended service intervals. Revisions to the Bosch HDEV6 control algorithm were implemented in 2021, improving long-term reliability of the fuel system.
All B6 5.2L engines comply with Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/6890), with full certification for UK and EU markets.
The Aston Martin B6 5.2L is a 5,204 cc twin-turbocharged V12 petrol engine engineered for hyper grand touring applications (2019–2023). It combines in-house V12 architecture with advanced turbocharging and direct injection to deliver extreme performance and refinement. Designed to meet Euro 6d, it balances flagship power with regulatory compliance.

The twin-turbo V12 delivers explosive acceleration and high-rpm refinement but demands strict adherence to 12,000-mile oil change intervals to protect the turbochargers and high-pressure fuel pump. Mobil 1 FS 0W-40 meeting AM-SPEC-004 is critical due to its thermal stability under extreme loads. Cold starts should be followed by light driving for 3–5 minutes to stabilise oil and coolant temperatures before aggressive use. Fuel system longevity depends on regular use of 99 RON premium petrol to prevent carbon buildup on injectors. Post-2021 models feature revised HPFP calibration; pre-2021 units should be checked per TSB-ENG-023 for early wear indicators.
Oil Specs: Requires Mobil 1 FS 0W-40 meeting AM-SPEC-004 (Aston Martin SIB 19 01 01). Supersedes ACEA C5.
Emissions: All B6 5.2L engines meet Euro 6d (WLTP RDE2) standards (VCA Type Approval #VCA/EMS/6890).
Power Ratings: Measured under SAE J1349 standards. Full output requires 99 RON fuel (Aston Martin TIS Doc. B6-PERF-01).

The Aston Martin B6 5.2L was used exclusively in the DBS Superleggera and DBS GT Zagato with longitudinal mounting and no licensed external applications. This engine received model-specific calibrations-aggressive boost mapping in the DBS GT Zagato and revised exhaust tuning in the DBS Superleggera-and from 2021 the facelifted DBS Superleggera adopted updated fuel control software, 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 front cylinder bank (Aston Martin TIS B6-ID-01). The 8th VIN digit indicates engine type ('B' for V12). All models feature black cam covers with 'B6' embossing. Critical differentiation from earlier VB6E: B6 uses Bosch ME17.9 ECU with circular diagnostic connector under the intake plenum, while VB6E uses Bosch ME7.1.1 with rectangular port. Service parts require model-year verification - HPFP units for pre-2021 engines are incompatible with post-2021 models due to firmware and pressure rating differences (Aston Martin TSB-ENG-023).
The B6 5.2L's primary reliability risk is high-pressure fuel pump degradation in early builds, with elevated incidence in track-focused use with frequent high-RPM operation. Internal Aston Martin quality reports from 2022 indicated a notable number of pre-2021 engines requiring HPFP replacement before 60,000 miles, while VCA records show related lean-burn and misfire faults in non-serviced vehicles. Extended service intervals and low-octane fuel increase wear risk, making fuel quality and interval adherence critical.
