The Land Rover 508PN is a 4,999 cc, V8 naturally aspirated petrol engine produced between 2011 and 2016. It was developed for high — torque performance in full — size luxury SUVs, featuring DOHC architecture, variable valve timing (VVT), and sequential multi — port fuel injection. In standard tuning, it delivered 276 kW (375 PS) and 510 Nm of torque, providing strong mid — range power for off — road and towing applications.
Fitted to the Range Rover (L322) and Range Rover Sport…
Production years 2011–2016 meet Euro 5 emissions standards (VCA UK Type Approval #VCA/EMS/508PN-E5).
The Land Rover 508PN is a 4,999 cc V8 petrol engine engineered for full-size luxury SUVs (2011–2016). It combines naturally aspirated displacement with variable valve timing to deliver linear power and high torque. Designed to meet Euro 5 standards, it balances performance with drivability in demanding conditions.

The Land Rover 508PN was used across Land Rover's L322/L320 platforms with longitudinal mounting and no licensed external applications. This engine received platform-specific adaptations-integrated oil cooler routing in the L320 and reinforced engine mounts in the L322-and from 2014 the facelifted L322 received the 5.0L Supercharged variant as standard, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The 508PN's primary reliability risk is high-pressure fuel pump degradation in early models, with elevated incidence in regions with variable fuel quality. Internal Land Rover field reports from 2014 indicated over 15% of pre-2014 units required fuel pump replacement before 120,000 km, while UK DVSA data shows increased catalytic converter failures linked to combustion irregularities. Extended idling and low-octane fuel use accelerate pump wear, making fuel quality and maintenance adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 508PN delivers strong performance and smooth operation, but early models (2011–2013) are prone to high-pressure fuel pump failures. Later revisions (2014+) improved pump durability with updated calibration and components. When maintained properly—using 98 RON fuel and adhering to oil service intervals—these engines can reliably exceed 150,000 km.
The main issues include high-pressure fuel pump failure (especially pre-2014), intake valve carbon buildup due to port injection, catalytic converter degradation from misfires, and oil leaks from aged valve/timing cover gaskets. These are documented in Land Rover TSBs and field service reports.
The 508PN was used exclusively in the Range Rover (L322) and Range Rover Sport (L320) from 2011 to 2016. It was the naturally aspirated 5.0L V8 option, distinct from the supercharged variant. No other Land Rover or Jaguar models used this specific engine configuration.
Yes, but with limitations. As a naturally aspirated engine, power gains from ECU remapping are modest (+15–25 kW). Significant increases require forced induction upgrades. Tuning must preserve fuel trim and ignition timing safety margins to avoid catalytic converter damage or detonation.
Moderate for its class. In combined driving, the Range Rover with 508PN averages ~13.0 L/100km (21.7 mpg UK). Highway driving improves to ~10.5 L/100km (26.9 mpg UK), while city use can exceed 16.0 L/100km (17.6 mpg UK). Real-world consumption depends heavily on driving style and vehicle load.
Yes. The 508PN is an interference engine. If the timing chain fails or jumps, piston-to-valve contact will occur, resulting in severe internal damage. Regular inspection of chain tensioners and guides is essential to prevent catastrophic failure.
Land Rover specifies SAE 5W-30 synthetic oil meeting TX1 specification. This oil is formulated for high-temperature stability and wear protection in V8 engines. Change intervals should not exceed 15,000 km or one year, whichever comes first, to ensure optimal engine longevity.
