The Range Rover 20 M4F Petrol is a 2,996 cc, inline‑six turbocharged petrol engine produced between 2024 and 2025. It features direct fuel injection, a twin — scroll turbocharger, and a 48V mild — hybrid electric vehicle (MHEV) system with DOHC architecture. In standard form it delivers 294 kW (400 PS) and 550 Nm of torque, providing strong low‑rpm response and refined highway performance.
Fitted exclusively to the L460 Range Rover (standard and long — wheelbase variants)…

All production years 2024–2025 meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/9012).
The Range Rover 20 M4F 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, responsive power and reduced turbo lag. Designed to meet Euro 6d standards, it balances performance with regulatory compliance and fuel efficiency.

The Range Rover 20 M4F 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 2024 the MY25 update introduced revised MHEV control logic, creating minor ECU interchange limits. All adaptations are documented in OEM technical bulletins.
The 20 M4F Petrol's primary reliability risk is intake valve carbon fouling in urban-driven vehicles, with elevated incidence in stop-start use under 15,000 km/year. JLR internal data from 2024 indicates a measurable uptick in misfire codes after 60,000 km in low-mileage fleets, while UK DVSA records show no significant emissions-related MOT failures due to robust GPF design. Short-trip driving and low-quality fuel make periodic intake cleaning 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 20 M4F Petrol offers refined performance and strong build quality, with no major mechanical flaws reported in early production. Carbon buildup on intake valves is the main concern, manageable with proper fuel and maintenance. Using JLR-specified 0W-20 oil and adhering to service intervals ensures longevity.
The most common issues are intake valve carbon fouling, minor oil consumption in early builds, MHEV belt tensioner wear in humid climates, and GPF regeneration faults from insufficient highway driving. All are documented in JLR service bulletins and typically avoidable with correct usage.
The 20 M4F Petrol (badged P400) 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 ~330–350 kW (450–475 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 ~10.2 L/100km (27.7 mpg UK). Real-world mixed driving typically yields 11–13 L/100km (21–25 mpg UK), depending on terrain and load. Highway cruising can achieve ~9 L/100km (31 mpg UK), while city driving may exceed 14 L/100km.
Yes. Like all modern Land Rover petrol engines, the 20 M4F 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.
