The Range Rover 12 HC32 Petrol is a 2,996 cc, inline‑six turbocharged petrol engine introduced in 2024. It features a 48V mild — hybrid electric vehicle (MHEV) system, direct fuel injection, and a twin — scroll turbocharger with DOHC architecture. In standard form it delivers 331 kW (450 PS) and 600 Nm of torque, providing responsive acceleration and refined performance across the rev range.
Fitted exclusively to the L460 Range Rover (standard and long — wheelbase variant…
All production years 2024–2025 meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/6789).
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.
The 12 HC32 Petrol's primary reliability risk is elevated oil consumption in early-production engines (Jan–Mar 2024), with incidence concentrated in vehicles subjected to frequent high-load driving or towing. JLR internal quality reports from Q1 2025 indicate ~8% of early units exceeded 0.5 L/1,000 km consumption, while UK DVSA records show no significant emissions-related MOT failures due to robust GPF design. Extended highway use and adherence to oil specifications make monitoring and mitigation critical.
Analysis derived from Jaguar Land Rover technical bulletins (2024–2025) and UK DVSA failure statistics (2024–2025). 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 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.
Yes. ECU remapping can safely increase output to ~370–390 kW (500–530 PS) on stock hardware. The MHEV system and robust internals support moderate tuning. However, JLR does not endorse modifications, and tuning may affect GPF function or warranty coverage.
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.
