The Land Rover 368DT Diesel is a 2,993 cc, inline-six turbo-diesel engine produced between 2020 and 2025. It features high-pressure common-rail fuel injection, a variable geometry turbocharger (VGT), and twin-independent variable cam timing (Ti-VCT). In standard tune, it delivers 250 kW (340 PS) and 700 Nm of torque, with overboost capability reaching 740 Nm, providing robust low-end response and strong towing performance.
Fitted to the Range Rover and Range Rover Sport, the 368DT Diesel was engineered for premium refinement and off-road capability. Emissions compliance was achieved through exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection, allowing it to meet Euro 6d emissions standards. Designed for drivers seeking maximum torque and smooth power delivery, this engine replaced older V6 diesel units to improve refinement and reduce NOₓ output.
One documented concern is premature high-pressure fuel pump (HPFP) wear, particularly in early 2020–2021 production models. This issue, referenced in Land Rover Technical Service Bulletin RT/TC/20/12, is linked to contamination or inadequate lubrication in the fuel rail. Later revisions included updated pump materials and revised fuel system diagnostics to improve longevity and reduce misfire incidents.
All 368DT Diesel models (2020–2025) comply with Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/9012).
The Land Rover 368DT Diesel is a 2,993 cc inline-six turbo-diesel engine developed for premium SUV applications (2020–2025). It combines common-rail direct injection with Ti-VCT and SCR-based aftertreatment to deliver responsive performance and improved emissions control. Engineered to meet Euro 6d standards, it balances on-road refinement with off-road capability.

The turbocharged inline-six design provides exceptional low-RPM torque ideal for towing and off-road use but requires adherence to 12,000 km oil change intervals using LR032278-specified 5W-30 oil to prevent premature timing chain and turbo wear. The SCR system demands regular AdBlue refills and proper exhaust temperatures to avoid regeneration failures. Early models (2020–2021) showed elevated HPFP failure rates under aggressive driving; updated pumps from 2022 onward improved durability. The engine's longitudinal mounting aids weight distribution in full-size SUV platforms. Regular fuel system maintenance and use of ultra-low sulfur diesel (ULSD) meeting EN 590 are recommended to maximize injector and pump longevity.

The Land Rover 368DT Diesel was used across Land Rover's Range Rover and Range Rover Sport platforms with longitudinal mounting and shared architecture with Jaguar for global premium SUV applications. This engine received platform-specific adaptations-tuned intake manifolds in the Sport and revised cooling routing in the Range Rover-and from 2022 the facelifted Range Rover L460 models adopted updated ECU calibrations for improved throttle response, creating interchange limits. Partnerships enabled Jaguar's 3.0L Ingenium diesel units to share core turbo and injection components. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the right-side cylinder block near the starter motor (Land Rover TIS LR-E368DT-009). The 8th VIN digit indicates engine type ('G' for 3.0H Diesel). Pre-2022 models have gloss black valve covers with silver accents; post-2022 units use full black covers. Critical differentiation from petrol variants: 368DT Diesel has a grey-topped high-pressure fuel pump and features a DPF and SCR system. Service parts require model-year verification—turbo actuators for pre-2022 Sport are not compatible with Range Rover due to ECU signal differences (Land Rover SIB RT/TC/20/12).
The 368DT Diesel's primary reliability risk is high-pressure fuel pump degradation, with elevated incidence in early production units. Internal Land Rover field reports from 2022 indicated a significant number of pre-2022 engines requiring HPFP replacement before 80,000 km, while UK DVSA MOT records show increased misfire-related failures in stop-start traffic. Aggressive driving and low-quality fuel exacerbate wear, making fuel quality and maintenance adherence critical.
