Overview of the Range Rover 4.4 V8 Engine

The Range Rover Engine 4.4 belongs to Jaguar Land Rover’s prestigious AJ-V8 family. It is an all-aluminium, 32-valve, dual-overhead-cam unit displacing 4,394 cc across eight cylinders. Known by engine codes 448PN and M62B44 / 448S2, it was fitted to the Range Rover L322 Vogue, Range Rover Sport L320, and Land Rover Discovery 3. In naturally aspirated form, it produces around 299 bhp (225 kW) and up to 440 Nm of torque. Jaguar engineers designed this unit specifically for Land Rover platforms, and it is also known internally as the AJ41. Its combination of smooth power delivery and low-down torque made it the benchmark for luxury 4×4 performance between 2004 and 2009.

Engine Codes: 448PN, M62B44, 448S2 and the AJ-V8 Family

Knowing the correct engine code is essential before buying a Range Rover Engine for sale. The 448PN is the Jaguar AJ41 petrol V8 used from 2004 to 2009. The earlier M62B44 and 448S2 are BMW-sourced variants from 2002–2004 that share architecture with BMW 5 and 7 Series engines. Both versions feature chain-driven cam timing, aluminium blocks, and multi-point fuel injection. Related engine codes in the AJ-V8 family include 508PN (5.0-litre naturally aspirated) and 508PS (5.0-litre supercharged). Always verify the engine code against your VIN number before ordering a reconditioned or replacement engine. At Engine Solutions, our team can confirm the correct fitment for you at no cost.
