The Range Rover 20 HD M 16 is a 2,996 cc, inline‑six turbocharged petrol engine produced between 2020 and 2023. It features a twin — scroll turbocharger, direct fuel injection, and DOHC valvetrain with variable valve timing. In standard form it delivers 294 kW (400 PS) and 550 Nm of torque, enabling strong performance with refined drivability.
Fitted exclusively to the L460 Range Rover and Range Rover Sport (2020–2023), the 20 HD M 16 was engineered for responsive power deli…
All production years 2020–2023 meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/9234).
The Range Rover 20 HD M 16 is a 2,996 cc inline‑six turbocharged petrol engine engineered for full-size luxury SUVs (2020–2023). It combines direct injection with a twin-scroll turbocharger to deliver smooth, linear power and responsive torque across the rev range. Designed to meet Euro 6d standards, it balances performance with regulatory compliance and everyday drivability.

The Range Rover 20 HD M 16 was used across Land Rover's L460 platform with longitudinal mounting and shared with the Range Rover Sport (L461). This engine received platform-specific adaptations—reinforced engine mounts in the L460 and revised cooling ducting in the L461—and from 2022 the mild-hybrid 48V system was standardised, though the base petrol variant retained identical core architecture. All adaptations are documented in OEM technical bulletins.
The 20 HD M 16's primary reliability risk is gasoline particulate filter (GPF) overloading in urban driving cycles, with elevated incidence in stop-start use under 10 km trips. Land Rover internal data (2022) indicates a measurable increase in regeneration-related fault codes in city-driven P400 models, while UK DVSA records show GPF-related warnings as a growing MOT advisory item. Short-trip usage without highway intervals increases soot accumulation, making driving pattern awareness critical.
Analysis derived from Land Rover technical bulletins (2020–2023) and UK DVSA failure statistics (2021–2025). 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 20 HD M 16 is generally robust when maintained properly. Its main vulnerability is GPF clogging in city driving, not mechanical failure. Using correct 0W-20 oil, 95 RON fuel, and ensuring regular highway driving greatly improves longevity. Early data (2020–2023) shows good reliability with adherence to service schedules.
The most frequent issues are GPF overloading from short trips, high-pressure fuel pump wear due to poor fuel or oil, turbo actuator calibration drift, and minor valve cover oil leaks. These are documented in Land Rover service bulletins LTB00612 and TIS updates.
This engine powers the P400 variant of the L460 Range Rover and L461 Range Rover Sport from 2020 to 2023. It is not used in Defender, Discovery, or older Range Rover generations. All applications are Euro 6d-compliant petrol models.
Yes. ECU remaps can safely increase output to ~330 kW (450 PS) on stock hardware. The inline-6 architecture and robust internals support moderate tuning. However, aggressive tuning without upgraded cooling or fueling may accelerate GPF or turbo wear. Always use a reputable tuner familiar with JLR systems.
Official WLTP combined is ~10.5 L/100km (27 mpg UK), but real-world mixed driving typically yields 11–13 L/100km (22–25 mpg UK). Highway cruising can achieve ~9 L/100km (31 mpg UK), while city driving may exceed 14 L/100km (20 mpg UK), especially with GPF regeneration cycles.
Yes. Like all modern DOHC engines, the 20 HD M 16 is an interference design. If the timing chain fails (extremely rare in this application), piston-to-valve contact can cause catastrophic damage. However, the chain is front-mounted and highly durable with proper oil maintenance.
It requires Jaguar Land Rover STJLR.03.5005 specification oil, typically SAE 0W‑20 synthetic. This is critical for HPFP lubrication, turbo protection, and emission system longevity. Do not substitute with generic ACEA oils—only JLR-approved formulations are validated.
