The Land Rover 37 L is a 2,996 cc, inline-six turbocharged petrol engine produced between 2023 and 2025 as part of JLR's Ingenium engine family. It features a high-pressure direct fuel injection system (up to 350 bar), twin-scroll turbocharger, and DOHC 24-valve configuration. In standard tune it delivers 294 kW (400 PS) with 550 Nm of torque available from 2,000 rpm, providing strong performance for luxury and high-speed driving applications.
Fitted to the Range Rover (L460) and Range Rover Sport (L461), the 37 L was engineered for premium refinement, dynamic on-road handling, and effortless towing capability. Emissions compliance is achieved through integrated gasoline particulate filter (GPF), variable valve timing (VVT), and cooled exhaust gas recirculation (cEGR), enabling Euro 6d compliance across all markets.
One documented reliability concern is premature turbocharger wastegate actuator sticking, particularly under sustained thermal load. This issue, highlighted in JLR Technical Service Bulletin PTT/107/24, affects early production units (2023–2024) and is linked to carbon buildup in the actuator linkage. From 2025, JLR introduced a revised actuator design with improved sealing and updated ECU calibration to reduce fault frequency.

All production years 2023–2025 meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/9123).
The Land Rover 37 L is a 2,996 cc inline-six turbocharged petrol engine designed for full-size luxury SUVs (2023–2025). It combines high-pressure direct injection with a twin-scroll turbocharger to deliver smooth power delivery and robust mid-range torque. Engineered to meet Euro 6d standards, it balances refinement, performance, and real-world emissions compliance.

The twin-scroll turbo provides strong mid-RPM torque ideal for highway and towing use but requires adherence to 16,000 km oil service intervals to prevent turbo bearing and timing chain wear. JLR STJLR.51.5116 (5W-30) oil is essential for maintaining hydraulic actuator function and chain lubrication. Short journeys and cold starts increase carbon buildup, necessitating periodic highway runs to maintain cEGR and GPF efficiency. The twin-scroll design is sensitive to oil contamination; use only OEM-specified oil to prevent wastegate actuator sticking. Post-2025 models feature revised actuator hardware; pre-2025 units benefit from the updated actuator upgrade per JLR SIB PTT/107/24.
Oil Specs: Requires JLR STJLR.51.5116 (5W-30) specification (JLR SIB PTT/107/24). Supersedes ACEA C2 standards.
Emissions: Euro 6d certification applies to all 2023–2025 models (VCA Type Approval #VCA/EMS/9123).
Power Ratings: Measured under SAE J1349 standards. Output consistent across EU markets with 95 RON fuel (JLR TIS Doc. ENG-6003).

The Land Rover 37 L was used across Land Rover's L460/L461 platforms with longitudinal mounting. This engine received platform-specific calibrations-exhaust tuning in the Range Rover and intake routing in the Range Rover Sport-and from 2025 the facelifted L461 adopted revised ECU mapping and actuator control, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine identification tag affixed to the front timing cover (JLR TIS ENG-6003). The 8th VIN digit indicates engine type ('7' for 3.0L Ingenium petrol). Pre-2025 models have silver turbo housings with black actuators; post-2025 units use dark grey turbo assemblies. Critical differentiation from 37 D: 37 L is petrol with GPF, while 37 D is diesel with SCR and AdBlue. Service parts require model year verification - turbo actuators for pre-2025 models are incompatible with post-2025 revisions due to control algorithm changes (JLR SIB PTT/107/24).
The 37 L's primary reliability risk is turbocharger wastegate actuator sticking in early units (2023–2024), with elevated incidence in mixed urban/highway use. JLR internal field reports from 2024–2025 indicated a significant share of pre-2025 units required actuator replacement before 100,000 km, while VCA MOT data links GPF clogging to frequent short trips. Extended idling and poor oil quality exacerbate turbo and emissions system stress, making service interval adherence and correct oil specification critical.
