The Aston Martin TM01 is a 3,998 cc, V8 twin — turbocharged petrol/hybrid engine introduced in 2025 as part of Aston Martin's new electrified performance architecture. It features a 90° V8 configuration with DOHC, 32 — valve layout, and an integrated electric motor producing a combined output of 535 kW (727 PS) and 800 Nm of torque. The hybrid system includes a 1.8 kWh lithium — ion battery pack and e — motor on the front axle for torque vectoring and all — wheel drive capability.…
All 2025 production units meet Euro 6d emissions standards .
The Aston Martin TM01 is a 3,998 cc V8 twin-turbocharged petrol/hybrid engine engineered for high-performance hybrid applications (2025). It combines a mid-mounted V8 with an electric motor on the front axle to deliver all-wheel drive capability and enhanced torque vectoring. Designed to meet Euro 6d standards, it balances extreme performance with regulated emissions.

The Aston Martin TM01 was used across Aston Martin's Valhalla platform with mid-engine mounting and no external licensing. This engine received platform-specific adaptations-bespoke intake manifolds, exhaust tuning, and hybrid control software-and from launch, adaptive hybrid control software to optimise power delivery, creating strict interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The TM01's primary reliability risk is high-voltage battery cooling system blockage under repeated track use, with elevated incidence in early production units. Internal Aston Martin field reports from 2025 indicate a low but notable share of launch models showing reduced hybrid assist before 30,000 km, while VCA MOT data shows minimal emissions-related failures. Short trips and infrequent servicing increase wear, making adherence to service intervals critical.
Analysis derived from Aston Martin technical bulletins (2025) and UK VCA failure statistics (2025). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The TM01 is fundamentally reliable when maintained properly. As a 2025 launch model, field data is limited, but no widespread defects have been reported. Regular oil changes with OEM-specified 0W-20 and use of premium fuel are essential for longevity. The hybrid system requires periodic inspection of cooling circuits and battery health. Well-maintained units are expected to exceed 120,000 km without major repairs.
The most documented issues are high-voltage battery cooling blockage (especially in early units), turbocharger wastegate actuator sticking, and intake manifold runner actuator faults. ECU software glitches have been addressed via reflashes. These are covered in Aston Martin service bulletins and engineering advisories.
The TM01 is used exclusively in the Aston Martin Valhalla (2025). It is a mid-mounted hybrid V8 powering the rear wheels with an electric motor on the front axle for AWD and torque vectoring. The engine is paired with a 9-speed automated manual transmission. No other Aston Martin models currently use this engine.
Aftermarket ECU tuning is common on the TM01 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Official combined consumption is ~14.2 L/100km (20 mpg UK) for the Valhalla. Real-world figures range from 16–20 L/100km (14–17 mpg UK) depending on driving style. In EV mode, the car can travel up to 15 km on electric power alone. Fuel quality significantly impacts efficiency—use 98 RON for best results.
Yes. The TM01 is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, resulting in catastrophic internal damage. This makes regular inspection and timely replacement of timing components critical. Any rattling at startup should be investigated immediately.
Aston Martin specifies SAE 0W-20 synthetic oil meeting API SP and ACEA C5 standards. Change intervals are 12,000 km or 24 months, whichever comes first. Using incorrect viscosity or lower-spec oil can accelerate turbo and timing chain wear and reduce engine longevity.
