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 Dynamic trims—the 20 T4G was engineered for smooth urban drivability and confident highway overtaking. Emissions compliance was achieved through direct fuel injection, variable valve timing, and a gasoline particulate filter (GPF), meeting Euro 6d standards across all production years.
One documented concern is premature wear of the high-pressure fuel pump (HPFP) drive lobe on the intake camshaft, which can lead to fuel pressure instability and misfires. This issue, highlighted in Land Rover Technical Service Bulletin LTB00712(21), is attributed to marginal surface hardening in early production camshafts. From late 2022, revised camshafts with improved metallurgy were introduced to address this weakness.
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 twin-scroll turbo provides immediate torque ideal for urban driving but requires strict adherence to 16,000 km oil change intervals using 0W-30 specification to protect the HPFP drive lobe and timing chain. Land Rover STJLR.03.5037 (0W-30) oil is critical due to its low-SAPS formulation and shear stability. Extended cold starts and short-trip driving accelerate GPF clogging and carbon buildup on intake valves. The Bosch HDEV6 system requires OEM-level diagnostics for injector coding and rail pressure adaptation. Post-2022 engines include updated camshafts per Land Rover SIB LTB00712(21); pre-2022 units should have camshaft inspection during HPFP replacement. GPF efficiency must be monitored to maintain Euro 6d compliance.
Oil Specs: Requires Land Rover STJLR.03.5037 (0W-30) specification (Land Rover SIB LTB00712(21)). Equivalent to ACEA C5 with OEM-specific additives.
Emissions: Euro 6d certification applies to all 2020–2024 models (VCA Type Approval #VCA/EMS/9321).
Power Ratings: Measured under ISO 1585 standards. Power output verified on dynamometer per Land Rover PT-2022.

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.
Locate the engine code stamped on the front timing cover near the oil filter housing (Land Rover TIS I4-20T4G-01). The 7th VIN digit indicates engine family ('T' for 2.0L turbo petrol). Pre-2022 models use camshafts with standard surface hardening; post-2022 units have camshafts marked with a green dot indicating revised metallurgy. Critical differentiation from Ingenium variants: 20 T4G uses Bosch HDEV6 with specific rail pressure map and GPF calibration. Service parts require production date verification—camshafts for engines before 11/2022 are incompatible with later units due to HPFP lobe redesign (Land Rover SIB LTB00712(21)).
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.
