The Land Rover 448DT is a 2,993 cc, inline-six turbo-diesel engine produced between 2018 and 2023. It belongs to the second-generation Ingenium engine family, designed for high torque output and improved refinement in full-size SUVs. Featuring high-pressure common-rail injection (up to 2,500 bar), a twin-scroll turbocharger, and dual overhead camshafts (DOHC), it delivers 170–184 kW (230–250 PS) and 500–570 Nm of torque, providing strong low-end pulling power for off-road and towing applications.
Fitted to the Range Rover Velar (L560), Range Rover Sport (L461), and Discovery (L462), the 448DT was engineered for longitudinal mounting in premium SUV platforms. Emissions compliance is achieved through dual-loop exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue dosing, enabling Euro 6d and US Tier 3 Bin 115 compliance across its production run. The engine features advanced thermal management and stop-start technology for improved efficiency.
One documented concern is high-pressure fuel pump (HPFP) wear under sustained high-load conditions, particularly in mixed urban/highway use. This issue, referenced in Land Rover Technical Service Bulletin TSB 017/20, is linked to fuel quality sensitivity and inadequate lubrication in early production batches. From 2020, revised HPFP internals and updated fuel calibration were implemented to improve durability.
Production years 2018–2023 meet Euro 6d and US Tier 3 Bin 115 standards (VCA UK Type Approval #VCA/EMS/6788).
The Land Rover 448DT is a 2,993 cc inline-six turbo-diesel developed for premium SUVs (2018–2023). It combines high-pressure common-rail injection with a twin-scroll turbocharger to deliver strong low-end torque and improved emissions performance. Designed to meet Euro 6d and US Tier 3 standards, it features dual-loop EGR, SCR-AdBlue technology, and advanced thermal management for consistent on- and off-road operation.

The 448DT provides strong low-RPM torque ideal for towing and off-road use but requires strict adherence to 16,000 km oil change intervals using approved 5W-30 STJLR.51.5004 oil to prevent HPFP and turbo wear. The Bosch CP4.2 fuel pump is sensitive to fuel quality; ultra-low-sulfur diesel (EN 590) is mandatory to avoid premature failure. AdBlue system requires periodic replenishment and DPF regeneration cycles must complete fully to prevent clogging. Post-2020 models feature revised HPFP components; pre-2020 units should be monitored for fuel pressure faults. Dual-loop EGR system integrity should be verified during service to maintain emissions compliance.
Oil Specs: Requires Jaguar Land Rover STJLR.51.5004 (5W-30) specification (Land Rover SIB 017/20). Supersedes ACEA C2.
Emissions: Euro 6d and US Tier 3 Bin 115 certification applies to all 2018–2023 models (VCA Type Approval #VCA/EMS/6788).
Power Ratings: Measured under SAE J1349 standards. 184 kW output requires EU5+ fuel quality (Land Rover TDS Doc. ING2-448DT-006).

The Land Rover 448DT was used across Land Rover's L560/L461/L462 platforms with longitudinal mounting and shared with Jaguar for flagship sedan applications. This engine received platform-specific adaptations-reinforced mounts in the Range Rover Sport and revised torque delivery in the Discovery-and from 2020 the facelifted Range Rover Velar adopted the 448DT with updated emissions calibration, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped vertically on the right-side engine block near the exhaust manifold (Land Rover TDS ING2-448DT-005). The 8th VIN digit indicates engine variant ('6' for 3.0L Ingenium diesel). Pre-2020 models have silver valve covers; post-2020 units use black. Critical differentiation from 306D1: 448DT uses Bosch CP4.2 fuel pump with square diagnostic connector and twin-scroll turbo layout. Service parts require build date verification - HPFP kits for pre-2020 engines are incompatible with later revisions (Land Rover SIB 017/20).
The 448DT's primary reliability risk is high-pressure fuel pump (HPFP) wear on early builds, with elevated incidence in mixed urban/highway use. Internal Land Rover quality reports from 2021 noted a significant share of pre-2020 engines requiring HPFP replacement before 120,000 km, while UK DVSA records show increased AdBlue-related faults in stop-start traffic. Short journeys and low-quality fuel increase pump and SCR stress, making fuel quality and service adherence critical.
