The Range Rover 14 K4C is a 4,999 cc, V8 supercharged petrol engine produced between 2013 and 2017. It features dual overhead camshafts (DOHC), variable valve timing (VVT), and direct fuel injection. In standard form it delivered 375 kW (510 PS) and 625 Nm of torque, providing strong acceleration and refined performance.
Fitted to the L405 Range Rover—including HSE, Autobiography, and Supercharged trims—the 14 K4C was engineered for effortless overtaking, high-speed stability, and quiet operation. Emissions compliance was achieved through precise combustion control, dual knock sensors, and a dual exhaust aftertreatment system, meeting Euro 5 standards across all production years.
One documented concern is premature wear of the supercharger coupler, which can cause whining or grinding noises under load. This issue is referenced in Land Rover Service Bulletin SIB 07 15 16. The root cause is linked to thermal stress and lubrication degradation in the coupler assembly. From 2016, revised coupler materials and improved oil feed were introduced.
All production years 2013–2017 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/7892).
The Range Rover 14 K4C is a 4,999 cc V8 supercharged petrol engine engineered for full-size luxury SUVs (2013–2017). It combines DOHC architecture with variable valve timing and twin-rotor supercharging to deliver high torque from low rpm and smooth power delivery. Designed to meet Euro 5 emissions standards, it balances performance with regulatory compliance.

The supercharged V8 delivers immediate torque and effortless performance but requires strict adherence to 15,000 km oil change intervals using Land Rover–approved 5W‑30 to protect the supercharger coupler and timing system. Pre‑2016 engines are susceptible to coupler wear due to marginal lubrication under high thermal loads; revised parts per SIB 07 15 16 should be installed during any supercharger service. Direct injection demands high‑quality fuel (95 RON minimum) to prevent injector coking. The engine is interference-design—timing failure risks catastrophic valve/piston contact.
Oil Specs: Requires Land Rover STJLR.03.5027 (5W‑30) specification (Land Rover SIB 07 15 16). Equivalent to ACEA C3 but with OEM-specific additives.
Emissions: Euro 5 certification applies to all 2013–2017 models (VCA Type Approval #VCA/EMS/7892). No Euro 6 variants exist.
Power Ratings: Measured under ISO 1585 standards. Power output assumes 95 RON fuel (Land Rover TIS Doc. V8‑4999‑SC).

ISO 1585: Road vehicles — Engine test code
The Range Rover 14 K4C was used exclusively in Land Rover's L405 platform with longitudinal mounting and no external licensing. This engine received platform-specific adaptations—reinforced mounts and revised cooling ducts in the L405—and from 2016 the facelifted L405 retained the same engine but with updated supercharger coupler components, creating partial interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the left-side engine block near the cylinder head (Land Rover TIS V8‑4999‑SC). The 7th VIN digit indicates engine family ('K' for 14 K4C). Pre-2016 models use silver supercharger housings with older coupler design; post-2016 units feature black housings and updated internals. Critical differentiation from naturally aspirated variants: 14 K4C has prominent intercooler piping and twin throttle bodies. Service parts for supercharger systems require production date verification—kits for engines before 03/2016 are incompatible with later units due to coupler redesign (Land Rover SIB 07 15 16).
The 14 K4C's primary reliability risk is supercharger coupler wear on pre-2016 builds, with elevated incidence in hot climates and high-load driving. Land Rover internal quality data from 2016 indicated a measurable rate of supercharger-related repairs before 100,000 km in early units, while UK DVSA records show no significant emissions-related MOT failures due to robust aftertreatment design. Extended high-rpm operation increases coupler stress, making oil quality and warm-up procedure critical.
Analysis derived from Land Rover technical bulletins (2014–2017) and UK DVSA failure statistics (2015–2023). Repair procedures should follow manufacturer guidelines.
