The Range Rover 20 H Petrol is a 3,996 cc, V8 twin — turbocharged petrol engine produced between 2024 and 2025. It features direct fuel injection, dual twin — scroll turbochargers, and a 48V mild — hybrid electric vehicle (MHEV) system with DOHC architecture. In standard form it delivers 423 kW (575 PS) and 750 Nm of torque, providing immediate throttle response and high — end power for dynamic performance and effortless towing.

All production years 2024–2025 meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/8901).
The Range Rover 20 H Petrol is a 3,996 cc V8 twin-turbocharged engine engineered for full‑size luxury SUVs (2024–2025). It combines a 48V mild-hybrid system with dual twin-scroll turbochargers to deliver seamless power delivery and reduced turbo lag. Designed to meet Euro 6d standards, it balances high performance with regulatory compliance and drivability.

The Range Rover 20 H Petrol was used across Land Rover's L460 platform with longitudinal mounting and no external licensing. This engine received platform-specific adaptations—reinforced subframes, active engine mounts, and upgraded cooling circuits—and from mid-2024 the MY25 update introduced revised BiSG pulley designs, creating minor interchange limits for MHEV components. All adaptations are documented in OEM technical bulletins.
The 20 H Petrol's primary reliability risk is premature wear of the MHEV belt-driven starter generator (BiSG) pulley bearings in vehicles subjected to frequent stop-start urban driving. JLR internal quality reports from Q3 2025 indicate ~6% of early units showed belt slippage or 48V system faults after 30,000 km under high-cycle use, while UK DVSA records show no significant emissions-related MOT failures due to robust GPF design. Adherence to MHEV service protocols and oil specifications is critical to mitigate wear.
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 20 H Petrol offers exceptional performance and refinement, with only early-production units showing BiSG pulley wear under aggressive urban use. Post-Q2 2024 builds include revised pulley bearings that mitigate this. Regular oil changes with JLR-specified 0W-20 oil and adherence to MHEV service intervals ensure long-term reliability.
The most common issues are BiSG pulley bearing wear in stop-start use, turbo oil coking after high-load driving, 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 20 H Petrol (badged P575) 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 ~460–490 kW (625–665 PS) on stock hardware. The robust V8 internals and MHEV system support moderate tuning. However, JLR does not endorse modifications, and tuning may affect GPF function or warranty coverage.
Official WLTP combined is ~13.2 L/100km (21.4 mpg UK). Real-world mixed driving typically yields 15–18 L/100km (16–19 mpg UK), depending on terrain and load. Highway cruising can achieve ~11.5 L/100km (24.5 mpg UK), while city driving may exceed 19 L/100km.
Yes. Like all modern Land Rover petrol engines, the 20 H 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.
