The Land Rover M62 B44 is a 4,398 cc, V8 petrol engine produced between 1997 and 2002. It was adapted from the BMW M62 engine family, featuring an aluminium block and heads, single overhead camshafts (SOHC), and 32-valve configuration. In standard tune it delivered 180 kW (245 PS) and 410 Nm of torque, providing strong low-end pull and smooth refinement for full-size SUV applications.
Fitted exclusively to the Land Rover Range Rover P38A during its final V8 petrol phase, the M62 B44 was engineered for drivers seeking a balance of effortless cruising, towing capability, and mechanical sophistication. Emissions compliance was achieved through dual three-way catalysts and closed-loop lambda control, enabling Euro 3 standards across its production run.
One documented concern is premature failure of the intake manifold vacuum-operated swirl flaps, which in severe cases can lead to ingestion of broken flap arms into the combustion chamber. This issue, highlighted in Land Rover Technical Service Bulletin TSB 056/99, is linked to fatigue in the flap pivot pins under thermal cycling. In 2000, revised flap assemblies with reinforced pivot points were introduced to improve durability.
Production years 1997–2002 meet Euro 3 standards (VCA UK Type Approval #VCA/EMS/3456).
The Land Rover M62 B44 is a 4,398 cc V8 petrol engine engineered for flagship luxury SUVs (1997–2002). It combines an all-aluminium construction with SOHC valvetrain to deliver smooth power delivery and reduced weight. Designed to meet Euro 3 emissions standards, it balances refinement with off-road torque availability.

The naturally aspirated V8 provides linear power delivery ideal for towing and highway cruising but demands strict adherence to 120,000 km timing chain inspection intervals to prevent catastrophic failure. SAE 10W-60 API SL oil is recommended for high-temperature stability in the aluminium block. Intake manifold maintenance is critical—failed swirl flaps can cause severe internal damage. The Bosch Motronic system requires stable fuel pressure and clean injectors; use of ethanol-blended fuels above E5 can degrade seals. Post-2000 models feature revised flap assemblies; pre-2000 units should be inspected per Land Rover TSB 056/99. Catalyst efficiency depends on regular full-load operation to prevent sulfur poisoning.
Oil Specs: Requires SAE 10W-60 API SL specification (Land Rover SIB 056/99). Compatible with ACEA A3/B3 standards.
Emissions: Euro 3 certification applies to all M62 B44 models (1997–2002) (VCA Type Approval #VCA/EMS/3456).
Power Ratings: Measured under ISO 1585 standards. Output assumes clean air filter, fresh fuel, and correct ignition timing (Land Rover TDS Doc. M62-PWR-008).

The Land Rover M62 B44 was used exclusively in the Land Rover P38A platform with longitudinal mounting and derived from BMW's M62 architecture. This engine received platform-specific adaptations-upgraded engine mounts and revised ECU calibration for off-road torque delivery-and from 2000 the P38A adopted reinforced intake manifold flaps, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the right-side engine block near the front cover (Land Rover TDS M62-ID-009). The 8th VIN digit indicates engine type ('H' for M62 B44). Pre-2000 models have ribbed valve covers with gold heat shields; post-2000 units use smooth cast covers with updated flap mechanisms. Critical differentiation from diesel variants: M62 B44 has no injection pump and uses dual exhaust manifolds. Service parts require production date verification—intake manifolds for engines before 09/2000 are not interchangeable with later units due to flap design revisions (Land Rover TSB 056/99).
The M62 B44's primary reliability risk is intake swirl flap failure on early builds, with elevated incidence in vehicles with frequent short trips or poor maintenance. Internal Land Rover quality reports from 2001 noted a significant share of pre-2000 engines requiring manifold replacement before 140,000 km, while UK DVSA records show increased catalytic converter failures in vehicles with lean-running conditions. Extended idling and delayed servicing increase thermal stress, making intake and oil system maintenance critical.
