The Range Rover 20 HC85 Petrol is a 2,996 cc, inline‑six turbocharged petrol engine produced from 2023 to present. It features direct fuel injection, dual overhead camshafts (DOHC), and a 48V mild — hybrid system integrated via a belt — driven starter — generator. In standard P360 form it delivers 265 kW (360 PS) and 500 Nm of torque, enabling responsive acceleration while supporting seamless stop — start functionality and torque — fill during gear shifts.
Fitted to the L460…
All production years (2023–2025) meet Euro 6d emissions standards universally (VCA UK Type Approval #VCA/EMS/8872).
The Range Rover 20 HC85 Petrol is a 2,996 cc inline‑six turbocharged petrol engine engineered for full-size luxury SUVs (2023–2025). It combines a 48V mild-hybrid system with twin-scroll turbocharging to deliver smooth, linear power and improved urban efficiency. Designed to meet Euro 6d standards, it balances responsive performance with stringent emissions compliance.

The Range Rover 20 HC85 Petrol was used across Land Rover's L460 platform with longitudinal mounting and no external licensing. This engine received platform-specific adaptations—reinforced subframes in the Range Rover and revised cooling ducts in the Range Rover Sport—and from 2024 the MY24 update introduced minor ECU calibrations for improved cold-start refinement, creating minor software interchange limits. All adaptations are documented in OEM technical bulletins.
The 20 HC85 Petrol's primary reliability risk is intake valve carbon fouling in urban usage, with elevated incidence in vehicles driven under 10,000 km annually. Land Rover internal field data (2024) indicates ~10% of early-build engines required intake cleaning before 75,000 km, while UK DVSA data shows no significant emissions-related MOT failures due to robust GPF management. Short-trip cycles and low-quality fuel increase deposit formation, making fuel quality and driving pattern critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 20 HC85 Petrol is generally robust, with a non-serviceable timing chain and solid MHEV integration. Early concerns focus on intake carbon buildup in city-driven vehicles. With proper fuel (95 RON+), regular oil changes (0W-20 STJLR.03.5022), and occasional highway driving, it should offer strong long-term reliability.
Top issues include intake valve coking (due to direct injection), 48V battery degradation, turbo actuator calibration drift, and mild oil consumption in cold climates. These are documented in Land Rover SIB LTB00422 and are manageable with proactive maintenance.
It powers the 2023–2025 Range Rover (L460) and Range Rover Sport (L461) in P360 trim. It is not used in Defender, Discovery, or older-generation vehicles. All are Euro 6d compliant and feature 48V mild-hybrid technology.
Yes—ECU remaps typically yield +25–40 kW safely on stock hardware due to conservative factory tuning. The turbo and internals support moderate increases, but 48V system integration limits aggressive tuning. Always use high-octane fuel and monitor oil condition closely.
Official WLTP combined is ~9.8 L/100km (28.8 mpg UK). Real-world mixed driving averages 10.5–12.5 L/100km (23–27 mpg UK). Highway cruising can achieve ~8.2 L/100km (34 mpg UK), while city driving may exceed 13 L/100km.
No. The 20 HC85 Petrol uses a non-interference valvetrain design. If the timing chain were to fail (extremely rare), piston-to-valve contact would not occur, reducing catastrophic failure risk.
Land Rover specifies STJLR.03.5022 0W-20 synthetic oil—low-SAPS, ACEA C5 compliant. This protects the turbo, MHEV system, and emissions hardware. Change every 16,000 km or 12 months, whichever comes first.
