The Range Rover 20 T2N is a 4,394 cc, V8 naturally aspirated petrol engine produced between 2006 and 2009. It features sequential electronic fuel injection (EFI), dual overhead camshafts (DOHC), and four valves per cylinder. In standard form it delivers 224 kW (306 PS) and 420 Nm of torque, providing smooth, refined performance with strong mid‑range response.

All production years (2006–2009) meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/6543).
The Range Rover 20 T2N is a 4,394 cc V8 naturally aspirated petrol engineered for full-size luxury SUV applications (2006–2009). It combines sequential electronic fuel injection with DOHC architecture and variable camshaft timing to deliver smooth, linear power and strong mid-range torque. Designed to meet Euro 4 emissions standards, it balances performance with regulatory compliance and drivability.

The Range Rover 20 T2N was used exclusively in Land Rover's L322 platform with longitudinal mounting. This engine received platform-specific adaptations—revised engine mounts and updated accessory drive routing—and from mid‑2008 the VCT solenoid was upgraded, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
The 20 T2N's primary reliability risk is VCT solenoid failure on early builds, with elevated incidence in high-mileage vehicles and those with infrequent oil changes. Land Rover internal quality data from 2009 indicated a measurable uptick in cam timing fault codes before 100,000 km, while UK DVSA records show no significant emissions-related MOT failures linked to this engine. Oil degradation and sludge formation accelerate solenoid clogging, making oil quality and interval adherence critical.
Analysis derived from Land Rover technical bulletins (2006–2009) and UK DVSA failure statistics (2009–2025). 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 T2N offers smooth, powerful V8 performance with modern DOHC architecture, but early models (2006–2007) had VCT solenoid concerns. Mid-2008 revisions improved durability. With proper maintenance—especially oil changes using 5W-30 STJLR.03.5002—well-cared-for examples can exceed 250,000 km reliably.
Top issues include VCT solenoid failure, oil sludge from infrequent oil changes, intake manifold gasket leaks, and water pump coolant leaks. These are documented in Land Rover SIB LTB00245(08) and TIS service procedures. Oil quality and driving pattern significantly influence longevity.
The 20 T2N powers the mid-cycle L322 Range Rover (2006–2009) in HSE and Vogue trims. It is a DOHC V8 distinct from the earlier OHV 20 H(EFI). All meet Euro 4 emissions with sequential EFI and three-way catalytic converters.
Yes. Stage 1 ECU remaps typically yield +20–30 kW safely, leveraging the robust DOHC architecture. Bolt-on upgrades (exhaust, cold air intake) offer modest gains. Significant power increases require camshaft or head work, which is uncommon due to cost.
In a L322 Range Rover, expect ~16.0 L/100km (city) and ~10.8 L/100km (highway), or ~22 mpg UK combined. Real-world mixed driving typically yields 19–24 mpg UK. Fuel consumption is higher than modern turbocharged engines due to displacement and architecture.
Yes. The 20 T2N is an interference engine. If the timing chain fails or jumps, piston-to-valve contact can cause catastrophic damage. Prompt attention to any timing-related fault codes is essential to prevent engine destruction.
Land Rover specifies 5W-30 synthetic oil meeting STJLR.03.5002 (or newer). This viscosity ensures proper VCT solenoid and cam phaser operation. Change intervals should not exceed 16,000 km or 12 months.
