The Range Rover 16 HC37 petrol engine is a 3,993 cc, twin-turbocharged V8 internal combustion engine produced between 2017 and 2023. It features dual overhead camshafts (DOHC), direct fuel injection, and twin-scroll turbochargers, delivering 331–423 kW (450–575 PS) and 625–750 Nm of torque. Variable valve timing and integrated exhaust manifolds enable responsive performance with reduced turbo lag.
Fitted to the L460 Range Rover and L461 Range Rover Sport—including HSE, Autobiography, and SV trims—the 16 HC37 was engineered to replace the supercharged AJ133 V8 with a more efficient, lower-emission powertrain while maintaining high-performance luxury characteristics. Emissions compliance was achieved through gasoline particulate filters (GPF), precise air-fuel control, and three-way catalytic converters, meeting Euro 6d standards across all production years.
One documented concern is premature wear of the high-pressure fuel pump cam follower, which can lead to loss of rail pressure and misfires. This issue is referenced in Land Rover Service Bulletin SIB-04-18-09. The root cause relates to insufficient lubrication under high thermal loads in early-design followers. From mid-2019, revised cam follower materials and lubrication channels were introduced to improve durability.
All production years 2017–2023 meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/9452).
The Range Rover 16 HC37 Petrol is a 3,993 cc twin-turbocharged V8 engineered for full-size luxury SUVs (2017–2023). It combines direct fuel injection with twin-scroll turbochargers to deliver high torque from low revs and sustained power at high rpm. Designed to meet Euro 6d emissions standards, it balances performance with regulatory compliance through GPF and advanced engine management.

The twin-turbo V8 delivers seamless power delivery and strong towing capability but requires strict adherence to 16,000 km oil change intervals using Land Rover–approved 0W‑20 oil to protect the high-pressure fuel pump cam follower and turbocharger bearings. Extended idling or frequent short trips accelerate cam follower wear due to oil aeration and thermal stress. The direct injection system is prone to intake valve coking; however, the inclusion of port injection in later variants mitigates this. High-pressure fuel pump noise or misfires should trigger immediate inspection per SIB 04 18 09. Use only EN 228–compliant premium unleaded (RON 95+).
Oil Specs: Requires Land Rover STJLR.03.5004 (0W-20) specification (Land Rover SIB 04 18 09). Not interchangeable with ACEA A5/B5.
Emissions: Euro 6d certification applies to all 2017–2023 16 HC37 petrol models (VCA Type Approval #VCA/EMS/9452).
Power Ratings: Measured under ISO 1585 standards. 423 kW output requires RON 98 fuel (Land Rover TIS Doc. V8-40TT-A3).

ISO 1585: Road vehicles — Engine test code
The Range Rover 16 HC37 Petrol was used across Land Rover's L460 and L461 platforms with longitudinal mounting and no external licensing. This engine received platform-specific calibrations—enhanced cooling in the L461 Sport and acoustic insulation in the L460—and from mid-2019 the L460/L461 adopted updated cam followers, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the left cylinder bank near the exhaust manifold (Land Rover TIS V8-40TT-ID). The 8th VIN digit indicates engine type ('M' for 4.0L twin-turbo petrol). Pre-mid-2019 units use silver cam follower housing; post-mid-2019 models feature black housing with ‘Rev B’ marking. Critical differentiation from supercharged 5.0L: 16 HC37 has twin turbochargers with integrated exhaust manifolds and gasoline particulate filter (GPF). Cam follower kits for pre-mid-2019 engines are incompatible with later units due to material and oiling channel changes (Land Rover SIB 04 18 09).
The 16 HC37's primary reliability risk is high-pressure fuel pump cam follower wear on pre-mid-2019 builds, with elevated incidence in high-ambient-temperature or towing use. Land Rover internal field data from 2020 indicated over 9% of early L461 V8 engines required cam follower replacement before 80,000 km, while UK DVSA records show increased MOT advisories linked to GPF regeneration faults in urban-driven examples. Extended idling and oil degradation accelerate wear, making oil quality and interval adherence critical.
