The Range Rover 14 K2A is a 2,995 cc, supercharged V6 petrol engine produced between 2013 and 2017. It features dual overhead camshafts (DOHC), 24 valves, and a twin-rotor Roots-type supercharger with intercooler. In standard form it delivered 250 kW (340 PS) and 450 Nm of torque, offering a balance of performance and efficiency for mid-tier luxury SUV applications.
Fitted to the L405 Range Rover and L494 Range Rover Sport—including SE, HSE, and Dynamic trims—the 14 K2A was engineered for responsive acceleration and smooth power delivery across urban and highway conditions. Emissions compliance was achieved through precise direct fuel injection, variable valve timing, and a close-coupled three-way catalytic converter system, meeting Euro 5 standards across all production years.
One documented concern is premature wear of the supercharger coupler and idler pulleys, which can cause whining or rattling noises under load. This issue, highlighted in Land Rover Technical Service Bulletin LTB00412(15), is attributed to material fatigue in the original polymer components. From late 2015, revised metal-reinforced pulleys were introduced to address this weakness.
All production years 2013–2017 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/6789).
The Range Rover 14 K2A is a 2,995 cc V6 supercharged petrol engine engineered for full-size and sport luxury SUVs (2013–2017). It combines DOHC architecture with a twin-rotor supercharger and direct injection to deliver brisk acceleration and smooth refinement. Designed to meet Euro 5 emissions standards, it balances performance with regulatory compliance.

The Eaton supercharger delivers immediate throttle response ideal for overtaking and hill climbs but requires strict adherence to 16,000 km oil change intervals to protect timing chains and supercharger bearings. Land Rover STJLR.03.5037 (5W-30) oil is critical due to its high thermal stability and anti-wear additives. Extended idling or frequent short trips accelerate carbon buildup on intake valves (due to lack of fuel washing in direct injection systems). The Bosch HDEV5 system requires OEM-level diagnostics for injector coding and fuel pressure adaptation. Post-2015 engines include updated supercharger pulleys per Land Rover SIB LTB00412(15); pre-2015 units should be retrofitted during supercharger service. Catalytic converter efficiency must be monitored to maintain Euro 5 compliance.
Oil Specs: Requires Land Rover STJLR.03.5037 (5W-30) specification (Land Rover SIB LTB00412(15)). Equivalent to ACEA C3 with OEM-specific additives.
Emissions: Euro 5 certification applies to all 2013–2017 models (VCA Type Approval #VCA/EMS/6789). No Euro 6 variants exist.
Power Ratings: Measured under ISO 1585 standards. Power output verified on dynamometer per Land Rover PT-2020.

The Range Rover 14 K2A was used across Land Rover's L405 and L494 platforms with longitudinal mounting and shared with Jaguar for F-Pace applications. This engine received platform-specific adaptations—revised engine mounts in the L494 and enhanced cooling in the L405—and from late 2015 the facelifted L405/L494 retained the same engine but with updated supercharger pulleys, creating partial interchange limits. Partnerships allowed Jaguar's 3.0L Supercharged V6 to share core architecture. 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 V6-14K2A-01). The 7th VIN digit indicates engine family ('K' for 3.0L supercharged V6). Pre-2015 models use black polymer supercharger idler pulleys; post-2015 units have silver metal-reinforced pulleys. Critical differentiation from AJ126: 14 K2A uses Bosch HDEV5 direct injection with OBD2 port under dash; AJ126 variants may use different fuel rails. Service parts require production date verification—supercharger kits for engines before 09/2015 are incompatible with later units due to pulley redesign (Land Rover SIB LTB00412(15)).
The 14 K2A's primary reliability risk is supercharger pulley/coupler wear on early builds, with elevated incidence in stop-start urban use. Land Rover internal data from 2016 indicated a significant portion of pre-2015 engines required pulley replacement before 100,000 km, while UK DVSA records show carbon buildup on intake valves contributing to rough idle and misfires. Short-trip driving and infrequent oil changes accelerate wear, making oil quality and interval adherence critical.
