The Range Rover 46F2F is a 2,996 cc, inline‑six turbocharged petrol engine produced between 2022 and 2025. It features a dual overhead camshaft (DOHC) layout with 24 valves, a 48‑volt mild‑hybrid system (MHEV), and electronic sequential fuel injection. In standard form it delivered 294 kW (400 PS) and 550 Nm of torque, providing refined performance with enhanced low‑end responsiveness typical of modern electrified powertrains.
Fitted exclusively to the L460 Range Rover and Range Rover Sport (2022–2025 MY), the 46F2F was engineered for smooth, quiet operation and strong real‑world efficiency. Emissions compliance was achieved through gasoline direct injection, variable valve timing, and a gasoline particulate filter (GPF), meeting Euro 6d-Final standards across all production markets.
One documented concern is intermittent fault codes related to the 48‑volt belt‑integrated starter generator (BISG), referenced in Land Rover Technical Service Bulletin LTB00703. This issue stems from software calibration mismatches under rapid load transitions, causing momentary power interruption or warning illumination. From Q3 2023, updated control module software (part number LR098765) resolved the majority of reported cases.
Production years 2022–2025 meet Euro 6d-Final standards (VCA UK Type Approval #VCA/EMS/9872).
The Range Rover 46F2F is a 2,996 cc inline‑six turbocharged petrol engine engineered for full-size luxury SUVs (2022–2025). It combines DOHC architecture with a 48‑volt mild-hybrid system and a twin-scroll turbocharger to deliver smooth, linear power and immediate torque response. Designed to meet Euro 6d-Final emissions standards, it balances performance with stringent regulatory compliance.

The inline‑six turbo delivers smooth, refined power with strong mid-range torque, ideal for relaxed highway cruising and responsive urban driving. The 48‑volt MHEV system enables engine stop/start and torque assist but requires a healthy 48V battery and BISG function. ACEA C5 0W‑20 oil is essential for GPF compatibility and turbo longevity. Extended oil change intervals (>16,000 km) risk GPF clogging and turbo bearing wear. Software-related BISG faults (pre-Q3 2023) should be addressed via TSB LTB00703 reflash. Consistent highway driving supports passive GPF regeneration.
Oil Specs: Requires ACEA C5 0W‑20 meeting Jaguar Land Rover specification STJLR.03.5010 (Land Rover TIS Doc. L460‑0120).
Emissions: Euro 6d-Final certification applies to all 2022–2025 models (VCA Type Approval #VCA/EMS/9872).
Power Ratings: Measured under ISO 1585 standards. Power figures verified on production dynamometers per Land Rover PT‑2023.

ISO 1585: Road vehicles — Engine test code
The Range Rover 46F2F was used exclusively in Land Rover's L460 platform with longitudinal mounting and no external licensing. This engine received platform-specific adaptations—integrated 48V BISG mounting, bespoke exhaust manifolding, and revised engine mounts—and remains in production as of 2025 with no direct successor announced. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the harmonic balancer (Land Rover TIS L460‑0005). The 8th VIN digit indicates engine displacement ('G' for 3.0L inline‑6). Visual identification: silver alloy valve cover with 'P400' badge on front grille and visible 48V battery in the engine bay. Critical differentiation from diesel variants: 46F2F has a single exhaust manifold and no EGR cooler. Service parts require software verification—BISG control modules before Q3 2023 may require update per Land Rover TSB LTB00703.
The 46F2F's primary reliability risk is software-related instability in the 48‑volt BISG system on early builds, with elevated incidence during aggressive driving or cold starts. Land Rover internal field data from 2023 indicated a notable share of pre-Q3 2023 vehicles reporting momentary power loss or warning lights, while UK DVSA records show GPF-related emissions faults in predominantly urban-driven examples. Short-trip usage and infrequent highway driving accelerate GPF saturation, making driving pattern and software version critical.
