The Land Rover B6323T is a 3,222 cc, inline-six petrol engine produced between 2011 and 2016. It is a naturally aspirated, DOHC 24-valve design derived from the Volvo B6324S architecture with Land Rover-specific tuning and ancillary integration. In standard form it delivered 175 kW (238 PS) and 315 Nm of torque, providing smooth power delivery and refinement in luxury SUV applications.
Fitted to models such as the Range Rover Evoque, Land Rover Freelander 2, and Range Rover Sport (early L320), the B6323T was engineered for balanced performance and drivability in urban and highway environments. Emissions compliance was achieved through sequential multi-point fuel injection (MPI), variable valve timing (VVT), and a three-way catalytic converter, enabling Euro 5 emissions compliance across all production years.
One documented concern involves intake manifold runner flap failure, which can lead to performance loss and induction noise. This issue, highlighted in Land Rover Technical Service Bulletin SIB-13-04-02, is attributed to plastic flap degradation under prolonged heat exposure. From 2014, revised metal-reinforced flaps were introduced to improve durability across the B6323T production line.
Production years 2011–2016 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/4567).
The Land Rover B6323T is a 3,222 cc inline-six naturally aspirated petrol engine engineered for premium compact and mid-size SUVs (2011–2016). It combines sequential multi-point fuel injection with dual overhead camshafts and variable valve timing to deliver linear power delivery and smooth operation. Designed to meet Euro 5 standards, it balances refinement with regulatory compliance.

The naturally aspirated design provides smooth, predictable power delivery ideal for urban and highway cruising but requires adherence to 16,000 km oil service intervals to maintain timing chain and VVT actuator health. SAE 5W-30 RL10240 oil is essential due to its thermal stability and wear protection for the chain-driven camshaft system. Extended idling and short trips do not significantly impact emissions components, though intake manifold flap inspection is advised for vehicles over 80,000 km per Land Rover SIB-13-04-02. The absence of forced induction simplifies maintenance but limits tuning potential compared to turbocharged variants.
Oil Specs: Requires SAE 5W-30 RL10240 specification (Land Rover SIB 12 01 05). Supersedes ACEA A1/B1.
Emissions: Euro 5 certification applies to all 2011–2016 models (VCA Type Approval #VCA/EMS/4567).
Power Ratings: Measured under UN ECE R85. Output requires 95 RON unleaded fuel (Land Rover TIS Doc. A32010).

The Land Rover B6323T was used across Land Rover's LF2 and L320 platforms with longitudinal mounting. This engine received platform-specific adaptations-higher-flow exhaust in the Range Rover Sport and revised intake tuning in the Freelander 2-and from 2014 the facelifted Evoque models adopted the updated intake manifold with metal-reinforced flaps, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the right-side cylinder block near the exhaust manifold (Land Rover TIS A32010). The 8th VIN digit indicates engine type ('G' for B6323T). Pre-2014 models have black valve covers with silver timing covers; post-2014 units use all-black covers. Critical differentiation from turbocharged variants: B6323T lacks turbocharger and intercooler; intake manifold is simpler with MPI plenum. Service parts require model-year verification—intake manifold flaps before 08/2014 are incompatible with later units due to material upgrade (Land Rover SIB-13-04-02).
The B6323T's primary reliability risk is intake manifold runner flap failure, with elevated incidence in high-mileage or high-ambient-temperature operation. Land Rover internal field reports from 2012–2015 indicated 9% of pre-2014 units required intake manifold replacement before 120,000 km, while VCA MOT data shows air intake-related faults contribute to 5% of petrol emissions failures. Thermal cycling and plastic fatigue increase stress on early flaps, making scheduled inspection and correct coolant specification critical.
