The Range Rover 14K2D petrol engine is a 3,000 cc, supercharged V6 internal combustion engine produced between 2013 and 2017. It features dual overhead camshafts (DOHC), direct fuel injection, and a twin-screw supercharger, delivering 250–280 kW (340–380 PS) and 450–460 Nm of torque. Variable valve timing and integrated charge cooling enable responsive performance with refined operation across the rev range.
Fitted to the L405 Range Rover and L494 Range Rover Sport—including SE, HSE, and Autobiography trims—the 14K2D was engineered to replace naturally aspirated V8s with a lighter, more efficient powertrain without sacrificing luxury or towing capability. Emissions compliance was achieved through precise air-fuel control, three-way catalytic converters, and secondary air injection, meeting Euro 5 and early Euro 6 standards depending on model year and market.
One documented concern is premature wear of the supercharger drive coupler, which can cause driveline vibration and whine under load. This issue is referenced in Land Rover Service Bulletin SIB-06-15-03. The root cause relates to elastomer degradation in the coupler under sustained thermal stress. From late 2015, revised coupler materials were introduced to improve service life.
Production years 2013–2014 meet Euro 5 standards; 2015–2017 models meet Euro 6 (VCA UK Type Approval #VCA/EMS/8921).
The Range Rover 14K2D Petrol is a 3,000 cc supercharged V6 engineered for full-size luxury SUVs (2013–2017). It combines direct fuel injection with a twin-screw supercharger to deliver strong low-end torque and smooth high-rpm power. Designed to meet Euro 5 and Euro 6 emissions standards depending on model year, it balances performance with regulatory compliance.

The twin-screw supercharger provides immediate throttle response and strong mid-range pull, but requires strict adherence to 16,000 km oil change intervals using Land Rover–approved 5W‑20 oil to protect supercharger bearings and timing components. Extended idling or frequent short trips accelerate supercharger coupler wear due to thermal cycling. The direct injection system is prone to intake valve coking; periodic walnut blasting may be needed after 90,000 km. Supercharger coupler noise (whine or chirp under load) is a known issue before late 2015—inspect per SIB 06 15 03. Use only EN 228–compliant premium unleaded (RON 95+).
Oil Specs: Requires Land Rover STJLR.03.5004 (5W-20) specification (Land Rover SIB 06 15 03). Not interchangeable with ACEA A5/B5.
Emissions: Euro 5 applies to 2013–2014 models; Euro 6 certification applies to 2015–2017 builds (VCA Type Approval #VCA/EMS/8921).
Power Ratings: Measured under ISO 1585 standards. 280 kW output requires RON 98 fuel (Land Rover TIS Doc. V6-30SC-A3).

The Range Rover 14K2D Petrol was used across Land Rover's L405 and L494 platforms with longitudinal mounting and no external licensing. This engine received platform-specific calibrations—revised cooling in the L494 Sport and enhanced NVH insulation in the L405—and from late 2015 the L405/L494 adopted updated supercharger couplers, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the supercharger pulley (Land Rover TIS V6-30SC-ID). The 8th VIN digit indicates engine type ('G' for 3.0L supercharged petrol). Pre-late-2015 units use black coupler housing with visible elastomer; post-late-2015 models feature reinforced black coupler with updated material marking. Critical differentiation from naturally aspirated 3.0L: 14K2D has twin intercoolers and Eaton supercharger. Supercharger coupler kits for pre-late-2015 engines are incompatible with later units due to geometry and durometer changes (Land Rover SIB 06 15 03).
The 14K2D's primary reliability risk is supercharger coupler degradation on pre-late-2015 builds, with elevated incidence in high-ambient-temperature or towing use. Land Rover internal field data from 2016 indicated over 12% of early L405 3.0L SC engines required coupler replacement before 90,000 km, while UK DVSA records show increased MOT advisories linked to driveline noise in high-mileage examples. Extended idling and oil degradation accelerate wear, making oil quality and interval adherence critical.
