The Range Rover 20 T4G is a 1,997 cc, turbocharged inline‑four petrol engine produced between 2020 and 2024. It features dual overhead camshafts (DOHC), 16 valves, and a single twin — scroll turbocharger with intercooling. In standard form it delivered 221 kW (300 PS) and 400 Nm of torque, offering a balance of efficiency and responsive performance for mid — tier luxury SUV applications.
Fitted to the L460 Range Rover and L461 Range Rover Sport—including SE, HSE, and Dynami…
All production years 2020–2024 meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/9321).
The Range Rover 20 T4G is a 1,997 cc inline‑four turbocharged petrol engine engineered for full-size luxury SUVs (2020–2024). It combines DOHC architecture with a twin-scroll turbocharger and direct injection to deliver brisk low-end torque and smooth refinement. Designed to meet Euro 6d emissions standards, it balances performance with modern regulatory compliance.

The Range Rover 20 T4G 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 late 2022 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 20 T4G'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 2022 indicated a notable share of pre-2022 engines required camshaft replacement before 80,000 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.
Analysis derived from Land Rover technical bulletins (2020–2024) and UK DVSA failure statistics (2021–2023). 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 T4G offers strong efficiency and responsive performance, but early models (2020–2021) had HPFP cam lobe wear concerns. Post-2022 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, intake valve carbon buildup, and turbo wastegate rattle. These are documented in Land Rover service bulletins LTB00712(21) and internal diagnostics reports, particularly in vehicles with short-trip driving or irregular servicing.
The 20 T4G powers the L460 Range Rover and L461 Range Rover Sport (2020–2024) in SE, HSE, and Dynamic trims. It is exclusive to Land Rover and not shared with Jaguar. All are Euro 6d compliant and represent the latest Ingenium-derived turbocharged inline‑4 architecture.
Yes. The 20 T4G responds well to ECU remapping, gaining +25–40 kW safely on stage 1. Supporting upgrades (intercooler, exhaust) can yield further gains. Most tuning focuses on optimizing boost control and torque delivery without overstressing the turbo or internals.
Real-world consumption is ~11.8 L/100km (city) and ~7.9 L/100km (highway), or about 24 mpg UK combined. Expect 22–26 mpg (UK) on mixed roads. Fuel economy is heavily influenced by driving style due to the turbocharged inline‑4 and vehicle weight.
Yes. The 20 T4G 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 and change it every 16,000 km or annually to protect the HPFP drive lobe and reduce sludge.
