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 (L320) from 2011 to 2016, the 508PN was engineered for premium driving refinement, smooth power delivery, and effortless cruising. Emissions compliance was achieved through integrated exhaust manifolds, precise air-fuel ratio control, and a dual three-way catalytic converter system, enabling Euro 5 standards across all markets.
One documented concern is premature failure of the high-pressure fuel pump (HPFP) on early 2011–2013 builds, highlighted in Land Rover Technical Service Bulletin TSB 0145/13. The issue is linked to inadequate lubrication due to fuel composition sensitivity. From 2014, revised fuel pump specifications and updated injector calibration were implemented to improve durability and fuel system longevity.
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 naturally aspirated V8 delivers smooth, predictable power ideal for towing and off-road use but requires strict adherence to 15,000 km oil service intervals to maintain timing chain and bearing longevity. SAE 5W-30 oil meeting Land Rover TX1 specification is essential for high-temperature stability and cam lobe protection. Extended idling or low-RPM operation should be minimized to prevent carbon buildup on intake valves. The fuel system is sensitive to low-octane or ethanol-blended fuels, which may trigger knock sensor adaptation and reduce performance. Post-2014 models feature updated HPFP and injector calibration; pre-2014 units should be inspected per Land Rover TSB 0145/13. Catalytic converters require periodic monitoring to prevent thermal degradation from misfires.
Oil Specs: Requires SAE 5W-30 meeting Land Rover TX1 specification (Land Rover SIB 0123/12). Equivalent to ACEA A3/B4.
Emissions: Euro 5 certification applies to all 2011–2016 models (VCA Type Approval #VCA/EMS/508PN-E5).
Power Ratings: Measured under SAE J1349 standards. Output assumes 98 RON fuel (Land Rover TDS Doc. A32100).

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.
Locate the engine identification tag affixed to the right-side cylinder head near the intake manifold (Land Rover TDS A32100). The 8th VIN digit indicates engine type ('5' for 5.0L V8). Pre-2014 models have silver intake manifolds with black valve covers; post-2014 units retain the same appearance but feature revised fuel pump calibration. Critical differentiation from supercharged variant: 508PN is naturally aspirated with no belt-driven compressor; supercharged models (510PN) have a large pulley at the front and intercooler plumbing. Service parts require model-year verification—fuel pumps for 2011–2013 models are incompatible with 2014+ due to internal design changes (Land Rover TSB 0145/13).
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.
