The Land Rover 508PS Petrol is a 5.0 L, V8 supercharged gasoline engine produced between 2020 and 2025. It powers high-performance variants of the Range Rover and Range Rover Sport, delivering 375 kW (508 PS) and 625 Nm of torque. Featuring direct fuel injection, variable valve timing, and an Eaton supercharger, this engine provides strong high-RPM power delivery and responsive throttle characteristics.
Fitted to the Range Rover (L405 facelift) and Range Rover Sport (L494), the 508PS engine was engineered for premium performance and towing capability. It includes intelligent stop/start technology and adaptive engine management to balance drivability with fuel efficiency. Emissions compliance is achieved through advanced catalyst systems and precise air-fuel control, meeting Euro 6d standards across all production years.
One documented concern is premature supercharger pulley bearing wear, noted in Land Rover Technical Service Bulletin TSB 09/21. This issue, affecting units produced before mid-2022, can lead to whining noises and eventual supercharger failure. From 2022 onward, revised pulley assemblies and updated lubrication protocols were implemented to improve long-term reliability.
All production years 2020–2025 meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/5678).
The Land Rover 508PS Petrol is a 4,999 cc V8 supercharged engine engineered for high-performance luxury SUVs (2020–2025). It combines direct fuel injection with an Eaton Roots-type supercharger to deliver aggressive throttle response and sustained power output. Designed to meet Euro 6d standards, it balances high-performance character with modern emissions and efficiency requirements.

The supercharged V8 delivers exhilarating top-end power ideal for high-speed driving but requires strict adherence to 15,000 km or annual oil service intervals to maintain supercharger health. Shell Helix Ultra 5W-30 (STJLR.51.5306) is critical due to its thermal stability and protection for high-load components. Extended idling and aggressive warm-up cycles should be avoided to prevent oil coking in the supercharger snout. Direct injection systems are prone to intake port carbon buildup; periodic cleaning is advised per Land Rover SIB 18 03 11. Post-2022 models feature upgraded supercharger pulley bearings; pre-2022 units should be inspected per TSB 09/21. Catalyst efficiency must be monitored to avoid DTCs and performance derates.
Oil Specs: Requires Shell Helix Ultra 5W-30 meeting STJLR.51.5306 specification (Land Rover SIB 16 01 20). Supersedes ACEA C3 and API SN.
Emissions: Euro 6d certification applies to all 2020–2025 models (VCA Type Approval #VCA/EMS/5678). Compliance verified under WLTP RDE2 protocols.
Power Ratings: Measured under SAE J1349 standards. Full output requires 98 RON fuel for optimal performance (Land Rover TDS Doc. A32150).

The Land Rover 508PS – Petrol was used across Land Rover's L405/L494 platforms with longitudinal mounting and no licensed external applications. This engine received platform-specific adaptations-higher-capacity cooling in the Range Rover Sport and reinforced torque mounts in the Range Rover-and from 2022 the facelifted L405 models adopted the 5.0L Supercharged V8 with revised supercharger internals, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine identification tag affixed to the front timing cover (Land Rover TDS A32175). The 8th VIN digit indicates engine type ('G' for 5.0L Supercharged V8). Pre-2022 models have silver supercharger housings; post-2022 units use black enamel finish. Critical differentiation from supercharger variants: Early 508PS uses M122-HE01 pulley; post-TSB units use M122-HE02 with reinforced bearing. Service parts require build date verification—supercharger kits for pre-06/2022 engines are incompatible with later revisions per TSB 09/21.
The 508PS – Petrol's primary reliability risk is supercharger pulley bearing wear on pre-2022 builds, with elevated incidence in high-temperature climates. Internal Land Rover quality reports from 2022 indicated a significant number of early units requiring supercharger service before 80,000 km, while VCA field data shows increased catalyst degradation in stop-start urban cycles. Hot shutdowns and extended idling increase thermal stress on the supercharger, making oil quality and operational habits critical.
Analysis derived from Land Rover technical bulletins (2020–2024) and UK DVSA failure statistics (2021–2024). Repair procedures should follow manufacturer guidelines.
