The Range Rover 25 K4F is a 4,999 cc, V8 supercharged petrol engine produced between 2022 and 2025. It features dual overhead camshafts (DOHC), variable valve timing (VVT), and direct fuel injection with enhanced thermal management. In standard form it delivered 441 kW (600 PS) and 750 Nm of torque, providing track — focused acceleration and refined high — speed dynamics.

All production years 2022–2025 meet Euro 6d standards .
The Range Rover 25 K4F is a 4,999 cc V8 supercharged petrol engine engineered for ultra-high-performance luxury SUVs (2022–2025). It combines DOHC architecture with twin-rotor supercharging and advanced thermal management to deliver immediate torque and sustained high-rpm power. Designed to meet Euro 6d emissions standards, it integrates dual GPFs and active engine cooling strategies for consistent performance under load.

The Range Rover 25 K4F was used exclusively in Land Rover's high-performance L460 platform with longitudinal mounting and no external licensing. This engine received platform-specific adaptations—carbon-fibre intake, performance-tuned active mounts, and enhanced cooling ducts in the SVAutobiography Dynamic SE—and from late 2023 the updated L460 retained the same engine but with revised supercharger pulley bearings, creating partial interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 25 K4F offers extreme supercharged V8 performance but early models (2022–late 2023) have supercharger pulley bearing concerns. Late-2023+ revisions improved durability significantly. With proper maintenance—especially oil changes using correct 5W-30 spec, premium 98 RON fuel, and post-drive cooldown—these engines can exceed 100,000 km reliably in spirited use.
Top issues include supercharger drive pulley bearing failure (pre-late-2023), dual GPF clogging from aggressive driving, intercooler hose delamination, and valve cover oil seepage. All are documented in Land Rover service bulletins, particularly SIB 03 23 24 for pulley concerns.
This 5.0L supercharged V8 powered the L460 Range Rover SVAutobiography and SVAutobiography Dynamic SE (2022–2025). It is the highest-output petrol engine ever fitted to a production Range Rover—distinct from the 423 kW 18 K4F used in earlier SVA models.
Aftermarket ECU tuning is common on the 25-K4F platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Real-world consumption is ~19.8 L/100km (city) and ~13.5 L/100km (highway), or about 14 mpg UK combined. Expect 12–16 mpg (UK) depending on driving style. Fuel demand increases dramatically under load or in urban stop-start conditions.
Yes. The 25 K4F is an interference engine. If the timing chain jumps or breaks, pistons can collide with open valves, causing severe internal damage. Prompt attention to any timing rattle is essential to prevent catastrophic failure.
Land Rover specifies SAE 5W-30 synthetic oil meeting STJLR.03.5027 (or equivalent ACEA C5 with OEM approval). Always use high-quality oil and change every 15,000 km or annually to protect the supercharger and timing system.
