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 long-wheelbase variants), the 99 H Petrol was engineered as an entry-level powertrain balancing efficiency, refinement, and drivability. Emissions compliance is achieved through gasoline particulate filtration (GPF) and precise lambda control, meeting Euro 6d standards across all markets.
One documented concern is premature wear of the MHEV belt-driven starter generator (BiSG) pulley bearings under frequent stop-start cycles, highlighted in Jaguar Land Rover Service Bulletin SIB‑MHEV‑2024‑01. This can lead to belt slippage, 48V system faults, and reduced idle-stop functionality. JLR recommends inspection of the BiSG pulley during major services and adherence to specified belt tension protocols.
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 twin-scroll turbo and 48V MHEV system provide accessible torque and refined idle-stop behavior but require strict adherence to JLR-specified 0W-20 oil (STJLR.03.5006) to protect turbo bearings and chain tensioners. Direct injection increases susceptibility to intake valve carbon buildup; use of Top Tier or EN 228-compliant fuel is recommended. The GPF system mandates occasional highway driving to enable passive regeneration. BiSG pulley wear is elevated in high-cycle urban use; inspect during major services per JLR SIB‑MHEV‑2024‑01.
Oil Specs: Requires JLR STJLR.03.5006 (0W-20) specification (JLR SIB‑OIL‑2023). Not interchangeable with ACEA C5 without verification.
Emissions: Euro 6d certification applies to all 2023–2025 models (VCA Type Approval #VCA/EMS/5432). Verified via RDE testing.
Power Ratings: Measured under ISO 1585 standards. Power output assumes 95 RON fuel (JLR TIS Doc. TIS‑L6‑2023).

ISO 1585: Road vehicles — Engine test code
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.
Locate the engine code stamped on the left-side cam cover near the MHEV belt drive (JLR TIS ENG‑ID‑2023). The 7th VIN digit for L460 petrol models is 'H' (indicating 3.0L inline‑6). Visual ID: silver cam cover with 'P300' badge on front grille. Differentiate from P400/P450 by output rating and ECU calibration. ECU part number must match production date—early 2023 units use Bosch MG1CS001; post-2023.5 use MG1CS002 with updated BiSG logic (JLR SIB‑ECU‑2024‑01).
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.
