The Range Rover 99 H Petrol is a 2,996 cc, inline‑six turbocharged petrol engine produced between 2023 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 221 kW (300 PS) and 400 Nm of torque, providing accessible performance with strong low‑rpm responsiveness for urban and highway use.
Fitted exclusively to the L460 Range Rover (standard and l…
All production years 2023–2025 meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/5432).
The Range Rover 99 H Petrol is a 2,996 cc inline‑six turbocharged engine engineered for full‑size luxury SUVs (2023–2025). 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 99 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 and active engine mounts—and from 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 99 H Petrol's primary reliability risk is BiSG pulley bearing wear in vehicles subjected to frequent stop-start urban driving. JLR internal quality reports from Q1 2024 indicate ~7% of early units showed belt slippage or 48V system faults after 35,000 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 (2023–2025) and UK DVSA failure statistics (2023–2025). 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 99 H Petrol offers refined performance and strong build quality, with only early-production units showing BiSG pulley wear under aggressive urban use. Post-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, intake valve carbon fouling, GPF saturation from urban driving, and minor oil consumption in early builds. All are documented in JLR service bulletins and manageable with proper maintenance and driving habits.
The 99 H Petrol (badged P300) is used in the L460 Range Rover (2023–2025), 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 ~260–280 kW (350–380 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 ~9.8 L/100km (28.8 mpg UK). Real-world mixed driving typically yields 10–12 L/100km (24–28 mpg UK), depending on terrain and load. Highway cruising can achieve ~8.5 L/100km (33 mpg UK), while city driving may exceed 13 L/100km.
Yes. Like all modern Land Rover petrol engines, the 99 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.
