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 Ro…
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 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.
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.
Analysis derived from Land Rover technical bulletins (2022–2025) and UK DVSA failure statistics (2015–2023). 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 46F2F offers smooth, refined inline‑six performance with strong efficiency. Early models (2022–mid‑2023) had BISG software issues, resolved via updates. With regular oil changes using ACEA C5 0W‑20, proper GPF regeneration through highway driving, and updated software, it can be dependable beyond 200,000 km.
Top issues include 48V BISG software instability (pre-Q3 2023), GPF clogging in short-trip use, turbo wastegate rattle, and high-pressure fuel pump noise. These are documented in Land Rover TSBs and commonly seen in urban-driven examples. Emissions-related faults are frequent without sufficient highway driving.
This engine is used only in the L460 Range Rover and L461 Range Rover Sport from model years 2022 to 2025 in the P400 MHEV variant. It is not shared with Jaguar or other brands. No transverse or licensed applications exist for this engine code.
Yes. The 46F2F responds well to ECU remapping, with stage 1 tunes yielding ~30–40 kW gains. Supporting modifications (downpipe, intercooler) allow further increases. However, excessive tuning may strain the 48V system and turbo. Most owners retain stock or mild tunes for daily reliability.
Real-world consumption is ~12.5 L/100km (city) and ~8.8 L/100km (highway), or about 23 mpg UK combined. Expect 21–25 mpg (UK) on mixed roads. Fuel economy suffers with short trips due to GPF regeneration demands and MHEV system inefficiency at low speeds.
Yes. The 46F2F is an interference engine. If the timing chain fails or jumps, piston-to-valve contact can cause catastrophic damage. Prompt attention to unusual engine noise or timing faults is essential to avoid major repairs.
Land Rover specifies SAE 0W‑20 synthetic oil meeting ACEA C5 and JLR STJLR.03.5010 standards. Change every 16,000 km or annually. Correct low-SAPS oil is vital for GPF protection and turbocharger bearing lubrication in the high-precision inline‑six.
