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—…
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 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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 14K2D offers strong performance and refinement, but early models (2013–mid-2015) have known supercharger coupler issues. Late-2015 onward revisions improved durability significantly. With strict oil changes (every 16,000 km) using correct 5W‑20 spec and avoidance of chronic short-trip driving, the engine can exceed 200,000 km reliably.
Top issues include supercharger coupler wear, intake valve coking due to direct injection, oil leaks from the valley cover, and coolant leaks from the plastic thermostat housing. All are documented in Land Rover service bulletins, particularly SIB 06 15 03 and TIS V6-30SC-A2.
The 3.0L supercharged V6 (14K2D) powered the L405 Range Rover (2013–2017) and L494 Range Rover Sport (2013–2017) across SE, HSE, and Autobiography trims. It was not used in Discovery or Defender models during this period.
Yes. The 14K2D responds well to ECU remapping, typically gaining +30–50 kW on stage 1 with stock hardware. Supporting upgrades (pulley, intercooler, exhaust) can push output beyond 450 PS. However, supercharger and drivetrain durability must be monitored closely under increased load.
Real-world consumption is moderate for a supercharged V6: expect 12–14 L/100km (20–24 mpg UK) combined. Highway cruising may reach 9.5 L/100km (30 mpg UK), but urban driving often exceeds 16 L/100km (18 mpg UK). Premium unleaded (RON 95+) is mandatory; RON 98 improves performance and reduces knock risk.
Yes. The 14K2D is an interference engine. If the timing chain jumps or breaks, pistons will contact open valves, causing catastrophic damage. Immediate attention to any timing-related noise is essential to prevent engine destruction.
Land Rover specifies SAE 5W‑20 synthetic oil meeting STJLR.03.5004. This low-viscosity oil is critical for supercharger bearing lubrication and timing system function. Oil must be changed every 16,000 km or annually, whichever comes first.
