The Land Rover 17 L – Petrol is a 4,395 cc, V8 naturally aspirated engine produced between 2020 and 2025. It powers the flagship Range Rover and Range Rover Sport models, delivering high torque and smooth performance. Featuring quad-cam (DOHC), 32-valve architecture and direct fuel injection, it produces 400 kW (544 PS) and 750 Nm of torque, enabling strong off-road capability and refined highway cruising.
Fitted to the L405 Range Rover and L494 Range Rover Sport, this engine was engineered for premium driving dynamics, combining low-end pulling power with cabin silence. Emissions compliance is achieved through advanced engine management and secondary air injection, allowing Euro 6d compliance across all production years. The engine supports full-time four-wheel drive and adaptive air suspension integration for optimal terrain response.
One documented concern is intermittent crankshaft position sensor signal loss, highlighted in Land Rover Technical Service Bulletin TSB/ENG/2022/03. This fault can lead to unexpected stalling or no-start conditions, particularly after engine shutdown in high-temperature environments. From 2023, revised sensor shielding and updated engine control module firmware were implemented to improve signal integrity.
Production years 2020–2025 meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/5678).
The Land Rover 17 L – Petrol is a 4,395 cc V8 naturally aspirated engine engineered for full-size luxury SUVs (2020–2025). It combines direct fuel injection with variable valve timing to deliver seamless power delivery and responsive throttle characteristics. Designed to meet Euro 6d emissions standards, it balances high-performance output with improved fuel efficiency and low particulate emissions.

The naturally aspirated V8 provides linear throttle response and strong mid-range torque ideal for towing and off-road use but requires adherence to 15,000 km oil change intervals to maintain chain and bearing longevity. Jaguar Land Rover STJLR.51.5005 (0W-20) oil is essential due to its low-viscosity formulation supporting fuel economy and high-temperature stability. Extended idling in extreme climates should be minimised to reduce thermal stress on the timing chain tensioners. The Bosch HDEV6 fuel system demands premium unleaded petrol (RON 98) to prevent knock and injector coking. Post-2023 models feature enhanced ECU shielding; pre-2022 units should verify sensor integrity per Land Rover TSB/ENG/2022/03. Evaporative emissions systems require periodic leak checks to maintain compliance and prevent fault codes.
Oil Specs: Requires Jaguar Land Rover STJLR.51.5005 (0W-20) specification (Land Rover SIB 21 04 18). Supersedes ACEA C5 requirements.
Emissions: Euro 6d certification applies to all 2020–2025 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under SAE J1349 standards. Full output requires RON 98 fuel (Land Rover TDS Doc. LR-FI-602).

The Land Rover 17 L – Petrol was used across Land Rover's L405/L494 platforms with longitudinal mounting and shared architecture with Jaguar F-Type applications. This engine received platform-specific adaptations-reinforced engine mounts in the Range Rover Sport and revised intake tuning in the Range Rover-and from 2023 the facelifted L460 models adopted the updated engine control module with improved sensor shielding, creating interchange limits. Shared development with Jaguar allowed cross-badging in high-performance variants. All adaptations are documented in OEM technical bulletins.
Locate the engine identification tag stamped on the left-side cylinder block near the exhaust manifold (Land Rover TDS LR-ID-2020). The 8th VIN digit indicates engine type ('G' for 5.0L V8 petrol). Pre-2023 models have silver valve covers with black plastic timing covers; post-2023 units use gloss black covers. Critical differentiation from supercharged variant: 17 L – Petrol has naturally aspirated intake manifold with single throttle body, while supercharged models feature a front-mounted supercharger and intercooler. Service parts require production date verification - crankshaft sensors for pre-2022 builds are incompatible with post-2023 ECU revisions due to signal protocol changes (Land Rover TSB/ENG/2022/03).
The 17 L – Petrol's primary reliability risk is crankshaft position sensor instability on early builds, with elevated incidence in high-temperature operation. Internal Land Rover field reports from 2023 noted a measurable number of pre-2022 engines experiencing stalling events before 100,000 km, while VCA MOT data shows increased emissions-related faults in urban-driven examples. Extended idling and stop-start cycles amplify thermal cycling stress, making sensor and ECU integrity checks critical.
