The Range Rover 492 4 SHIRG is a 4,367 cc, V8 twin‑turbocharged petrol engine produced between 2022 and 2025. It features direct fuel injection, variable valve timing (VVT) with DOHC architecture, and a cross‑plane crankshaft for enhanced acoustic refinement. In standard form it delivers 441 kW (600 PS) and 750 Nm of torque, enabling blistering acceleration while maintaining composure at high speeds.
Fitted exclusively to the L460 Range Rover SV and L461 Range Rover Spo…
All production years 2022–2025 meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/9245).
The Range Rover 492 4 SHIRG is a 4,367 cc V8 twin‑turbocharged petrol engineered for flagship luxury SUVs (2022–2025). It combines high-pressure direct injection with twin‑scroll turbochargers to deliver explosive power and seamless refinement. Designed to meet Euro 6d standards, it balances extreme performance with stringent emissions control.

The Range Rover 492 4 SHIRG was used across Land Rover's L460 and L461 platforms with longitudinal mounting and no third‑party licensing. This engine received platform-specific adaptations—enhanced cooling in the L461 Sport SV and revised engine mounts in the L460 SV—and from Q4 2023 the HPFP upgrade per JLR Service Action Notice, creating minor service part distinctions. All adaptations are documented in OEM technical bulletins.
The 492 4 SHIRG's primary reliability risk is high-pressure fuel pump (HPFP) cam follower wear, with elevated incidence in vehicles subjected to repeated hot restarts or track use. JLR internal field data from 2024 indicated a measurable uptick in HPFP-related DTCs before 50,000 km in pre‑Q4 2023 builds, while UK DVSA records show minimal emissions-related failures due to robust GPF and EGR control. Thermal cycling without cooldown increases mechanical stress on the cam-follower interface, making driving habit and service adherence critical.
Analysis derived from Jaguar Land Rover technical bulletins (2022–2025) and UK DVSA failure statistics (2022–2025). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The 492 4 SHIRG offers exceptional performance and refinement, but early units (2022–Q3 2023) had HPFP cam follower wear concerns under repeated hot restarts or track use. Post‑Q4 2023 revisions significantly improved durability. With proper maintenance—especially oil changes and cooldown periods after high-load use—this engine can be very dependable.
Main issues include HPFP cam follower wear, GPF regeneration faults from low-speed driving, turbo wastegate rattle, and rear main seal oil seepage. These are documented in JLR service bulletins and are generally manageable with correct servicing.
The 492 4 SHIRG powers the SV variants of the L460 Range Rover and L461 Range Rover Sport (2022–2025). It is exclusive to Land Rover and not shared with other manufacturers.
Yes. ECU remaps typically yield +50–90 kW safely on stock hardware, as the V8 architecture and forged internals handle increased boost well. Supporting upgrades (intercooler, downpipes) help sustain reliability. Always use 98 RON fuel with tuned maps.
In a Range Rover SV, expect ~15.2 L/100km (city) and ~10.5 L/100km (highway), or about 18 mpg UK combined. Real-world mixed driving typically yields 16–20 mpg UK, depending on load and driving style.
Yes. Like all modern JLR engines, the 492 4 SHIRG is an interference design. Timing chain failure—though rare—could cause piston-to-valve contact and severe internal damage. Chain wear is minimal with proper oil maintenance.
JLR specifies 0W‑20 synthetic oil meeting STJLR.03.5037. Always use this exact grade to ensure VVT response, turbo protection, and HPFP lubrication. Change every 16,000 km or 12 months, whichever comes first.
