The Aston Martin RCR V12 is a 5,935 cc, naturally aspirated V12 petrol engine produced between 2005 and 2012. It features a 60° V12 configuration, DOHC valvetrain, and Bosch Motronic ME9.8 port fuel injection, delivering 380 kW (517 PS) and 570 Nm of torque. Its high — revving character and smooth power delivery were engineered for grand touring performance, with a redline of 7,000 rpm.
Fitted to the DB9, V8 Vantage (early prototypes), and DBS (2007–2012), this engine was de…

The Aston Martin RCR V12 is a 5,935 cc naturally aspirated petrol engine developed for grand touring applications (2005–2012). It features a 60° V12 layout with dual overhead camshafts per bank and sequential port fuel injection, delivering smooth power progression and responsive throttle characteristics. Designed to meet Euro 4 emissions standards, it balances traditional refinement with modern engine management.

The Aston Martin RCR V12 was used in the DB platform with longitudinal mounting and developed under in-house engineering. This engine received platform-specific tuning—optimized intake manifolds in the DBS and revised exhaust headers in facelifted variants—and from 2009 the updated DB9 Series 2 adopted a higher-lift cam profile and modified ECU calibration, creating 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.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The RCR V12 offers exceptional refinement and performance, but requires meticulous maintenance. Early models (2005–2008) had cam phaser solenoid issues, and all variants are sensitive to timing chain neglect. With strict adherence to service intervals and use of high-octane fuel, these engines can achieve 140,000 km reliability. Regular inspections and proactive part replacement are essential for longevity.
Key issues include camshaft phaser solenoid failure, timing chain tensioner wear, intake vacuum leaks, and fuel injector clogging. These are documented in Aston Martin service bulletins. Preventive maintenance—especially timely solenoid inspection and oil changes—significantly reduces risk of major repairs.
The RCR V12 powers the DB9 (2005–2012), DBS (2007–2012), and early Vanquish development mules. It is longitudinally mounted and tuned for grand touring performance. No cross-manufacturer applications are documented. This engine was succeeded by the Ford-derived 5.9L and later 6.0L V12 units.
Yes, though tuning is limited by the naturally aspirated design. ECU remapping and performance camshafts can yield +30–50 kW. Upgraded exhausts, intake systems, and lightweight components enhance responsiveness. Tuning must preserve valve timing and thermal management limits to avoid reliability issues. Classic specialists offer bespoke tuning packages.
In combined driving, expect ~16.5 L/100km (17.1 mpg UK). Highway cruising can achieve ~12.0 L/100km (23.7 mpg UK), while city driving may exceed 20 L/100km (14.3 mpg UK). Real-world consumption depends heavily on driving style, fuel quality, and vehicle condition.
Yes. The RCR V12 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 5W-50 synthetic oil. Change intervals are 12,000 km or annually. Using correct oil ensures proper camshaft, chain, and VVT system lubrication, reducing wear and maintaining performance. Extended drain intervals risk chain slippage and bearing wear.
