All production years 2024–2025 meet Euro 6d emissions standards .
The Range Rover 12 HC32 Petrol is a 2,996 cc inline‑six turbocharged engine engineered for full‑size luxury SUVs (2024–2025). It combines a 48V mild-hybrid system with twin-scroll turbocharging to deliver smooth, high-output performance and reduced turbo lag. Designed to meet Euro 6d standards, it balances dynamic capability with regulatory compliance and fuel efficiency.

The Range Rover 12 HC32 Petrol was used across Land Rover's L460 platform with longitudinal mounting and no external licensing. This engine received platform-specific adaptations—reinforced subframes and active engine mounts—and from mid-2024 the MY25 update introduced revised piston ring specifications, creating minor interchange limits for short-block components. 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 12 HC32 Petrol offers strong performance and refinement, with only early-production units (Jan–Mar 2024) showing elevated oil consumption under high-load use. Post-Q2 2024 builds include piston ring revisions that resolve this. Regular oil checks and use of JLR-specified 0W-20 oil ensure long-term reliability.
The most common issues are elevated oil consumption in early builds, MHEV BiSG control sensitivity in cold weather, GPF saturation from urban driving, and intake valve carbon buildup. All are documented in JLR service bulletins and manageable with proper maintenance and driving habits.
The 12 HC32 Petrol (badged P450) is used in the L460 Range Rover (2024–2025), including standard and long-wheelbase variants. It is not used in Sport, Velar, or Discovery models. There is no cross-manufacturer licensing; this engine is exclusive to Land Rover.
Aftermarket ECU tuning is common on the 12-HC32 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 WLTP combined is ~11.0 L/100km (25.7 mpg UK). Real-world mixed driving typically yields 12–14 L/100km (20–23 mpg UK), depending on terrain and load. Highway cruising can achieve ~9.5 L/100km (30 mpg UK), while city driving may exceed 15 L/100km.
Yes. Like all modern Land Rover petrol engines, the 12 HC32 Petrol is an interference design. Timing chain failure—though rare—could cause piston-to-valve contact and catastrophic damage. Chain maintenance is critical, though no widespread failures have been reported as of 2025.
JLR specifies SAE 0W‑20 oil meeting STJLR.03.5006 standard. Always use a high-quality synthetic designed for turbocharged, direct-injection engines with MHEV systems. Change intervals should not exceed 20,000 km or 12 months, whichever comes first.
