Production years 2025–present meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/5678).
The Aston Martin AM01 is a 3,998 cc V8 twin-turbo petrol engine engineered for grand touring applications (2025–present). It combines a hot-V architecture with direct injection and variable valve timing to deliver high specific output and linear power delivery. Designed to meet Euro 6d standards, it balances exhilarating performance with improved efficiency and emissions control.

The Aston Martin AM01 was used across Aston Martin's DB platform with longitudinal mounting. This engine received platform-specific tuning-for increased torque delivery in the DB12 Grand Tourer-and from 2025 integrates a 48V mild-hybrid system (AM01-MH), creating interchange limits with non-hybrid variants. All adaptations are documented in OEM technical bulletins.
The AM01's primary reliability consideration is thermal management of turbochargers and GPFs under sustained high load, with early data indicating potential for coking in short-trip driving. Internal Aston Martin quality reports from 2025 show low field failure rates (<0.5%) across the first 12 months, while VCA in-service monitoring confirms high compliance with emissions standards. Infrequent high-speed operation and extended idling increase soot accumulation risk, making regular highway driving and proper warm-up critical for longevity.

The most common questions about engine codes, what they mean, how to find them and how this database works
As a 2025 launch engine, long-term reliability data is limited. However, initial field reports and Aston Martin's internal quality metrics show excellent durability with failure rates below 0.5% in the first year. The dual-chain timing and robust turbo design suggest strong potential, provided recommended service intervals and high-quality fuel (98 RON) are used. The 48V hybrid system adds complexity but is designed for 150,000 km lifespan.
The most documented concerns are turbocharger coking from inadequate cooldown, GPF regeneration failures due to short journeys, and 48V hybrid system faults from battery degradation. Oil consumption above spec has been noted in a small number of early units. These are addressed in Aston Martin service information bulletins with specific diagnostic and repair protocols.
The AM01 is currently fitted exclusively to the DB12 Grand Tourer (2025–present), including both Coupe and Volante variants. It is expected to be used in future V8-powered Aston Martin models. The engine is not licensed to other manufacturers and is built at Aston Martin's dedicated engine facility in Cologne, Germany.
Yes, the AM01 has significant tuning potential due to its robust internals and twin-turbo setup. Stage 1 ECU remaps typically yield +50–70 kW, while supporting modifications (intake, exhaust, intercooling) enable higher outputs. However, tuning may void warranty and impact emissions compliance. OEM-approved performance upgrades are expected to be offered through Aston Martin Accessories.
Official WLTP combined consumption is 12.8 L/100 km (~22.0 mpg UK). Real-world figures vary significantly: expect 14–16 L/100 km (~17.7–19.6 mpg UK) in mixed driving, but consumption can exceed 20 L/100 km (~14.1 mpg UK) under hard use. Highway cruising at legal speeds returns approximately 9.5 L/100 km (~29.7 mpg UK). GPF regeneration cycles temporarily increase fuel use.
Yes. The AM01 is an interference engine, meaning that if the timing chains fail or jump, the pistons can contact the valves, resulting in severe internal damage. The dual-chain system is designed for the engine's lifespan, but adherence to oil change intervals is critical to prevent chain wear and ensure proper tensioner function.
Aston Martin specifies SAE 0W-20 synthetic oil meeting AMOB-001 specification (equivalent to ACEA C5 and API SP). Oil must be changed every 15,000 km or annually. Using correct oil ensures optimal performance of the variable valve timing system, piston cooling jets, and turbocharger bearings. Non-compliant oils may lead to increased wear and DPF/GPF contamination.
