The Range Rover F 18 A3 is a 2,996 cc, turbocharged inline‑six petrol engine produced between 2018 and 2023. It features dual overhead camshafts (DOHC), 24 valves, and a single twin — scroll turbocharger with an integrated 48V mild — hybrid system (MHEV). In standard form it delivered 294 kW (400 PS) and 550 Nm of torque, offering refined performance with enhanced low — end response and improved fuel efficiency for luxury SUV applications.

All production years 2018–2023 meet Euro 6d-Temp standards (VCA UK Type Approval #VCA/EMS/8765).
The Range Rover F 18 A3 is a 2,996 cc inline‑six turbocharged petrol engine with 48V mild-hybrid assistance engineered for full-size luxury SUVs (2018–2023). It combines DOHC architecture with a twin-scroll turbocharger and direct injection to deliver smooth, linear power and immediate torque response. Designed to meet Euro 6d-Temp emissions standards, it balances performance with modern regulatory compliance.

The Range Rover F 18 A3 was used across Land Rover's L460 and L461 platforms with longitudinal mounting. This engine received platform-specific adaptations—revised engine mounts in the L461 and enhanced cooling in the L460—and from mid-2021 the updated L460/L461 retained the same engine but with revised camshafts, creating partial interchange limits. All adaptations are documented in OEM technical bulletins.
The F 18 A3's primary reliability risk is high-pressure fuel pump (HPFP) drive lobe wear on early builds, with elevated incidence in frequent cold-start urban use. Land Rover internal data from 2021 indicated a notable share of pre-2021 engines required camshaft replacement before 90,000 km, while UK DVSA records show GPF clogging contributing to reduced performance in short-trip driving. Infrequent oil changes and poor-quality fuel accelerate wear, making oil quality and interval adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The F 18 A3 offers refined performance and strong efficiency, but early models (2018–2020) had HPFP cam lobe wear concerns. Post-2021 revisions improved durability. With proper maintenance—especially oil changes every 16,000 km using correct 0W-30 spec—these engines can exceed 200,000 km reliably.
Top issues include HPFP drive lobe wear, GPF clogging, 48V mild-hybrid system faults, and intake valve carbon buildup. These are documented in Land Rover service bulletins LTB00645(20) and internal diagnostics reports, particularly in vehicles with short-trip driving or irregular servicing.
The F 18 A3 powers the L460 Range Rover and L461 Range Rover Sport (2018–2023) in HSE, Autobiography, and Dynamic trims. It is exclusive to Land Rover and not shared with Jaguar. All are Euro 6d-Temp compliant and feature 48V mild-hybrid technology.
Yes. The F 18 A3 responds well to ECU remapping, gaining +30–50 kW safely on stage 1. Supporting upgrades (intercooler, exhaust) can yield further gains. Most tuning preserves the 48V system functionality while optimizing boost and torque curves.
Real-world consumption is ~12.4 L/100km (city) and ~8.3 L/100km (highway), or about 23 mpg UK combined. Expect 21–25 mpg (UK) on mixed roads. Fuel economy benefits from the 48V system during urban driving but is influenced by vehicle weight and driving style.
Yes. The F 18 A3 is an interference engine. If the timing chain jumps or tension is lost, pistons can contact valves, causing catastrophic damage. Prompt attention to timing rattle or fault codes is essential to prevent engine failure.
Land Rover specifies SAE 0W-30 oil meeting STJLR.03.5037 (or newer). Always use a high-quality synthetic designed for turbocharged petrol engines with mild-hybrid systems and change it every 16,000 km or annually to protect the HPFP drive lobe and reduce sludge.
