). Unlike its predecessor and successor, there was no M version of the N62. In the International Engine of the Year awards in 2002, the N62 was awarded "International Engine of the Year", "Best New Engine" and "Above 4-litre" categories.

Design

The N62 was a clean sheet design and not a direct evolution of the M60 engine line that evolved into the M62 engine. The N62 has a bore of and stroke of for a total displacement of 4,398cc and features double-VANOS

variable valve timing In internal combustion engines, variable valve timing (VVT) is the process of altering the timing of a valve lift event, and is often used to improve performance, fuel economy or emissions. It is increasingly being used in combination with varia ...

on both the intake and exhaust camshafts (the M62 features variable valve timing on only the intake camshaft). As per the M62, the N62 has double overhead camshafts (DOHC) with four valves per cylinder, an aluminium engine block, an aluminium cylinder head and offset fracture-split forged powdered metal

s. It was also the first V8 and only the second BMW engine to feature Valvetronic technology which on the N62 varies the valve lift of the engine from .03mm to 9.85mm. The redline is 6500 rpm. Valvetronic technology allows for variable valve timing, variable lift and variable duration and the N62 adjusts the lift instead of utilizing the throttle body during normal operation. The engine does feature a throttle body but this is only used for emergency applications in the event of Valvetronic failure and for certain cold start conditions. A vacuum pump is mounted to cylinder bank 1 to supply vacuum for the brake booster and secondary air injection ports. The N62B44 is the only production engine in the world to feature a continuously variable length intake manifold known as the DIVA intake (not to be confused with the DISA intake as used on many other BMW production engines). The intake length path begins to shorten at 3,500 and is progressively shortened until it reaches it's shortest length at the engine's redline. Applications: * 2004-2005

X5 4.4i The N62B48 engine used in the E53 X5 4.8is was a 4.8L variant of the N62B44 which still utilized many features of the N62B44 such as the DIVA intake manifold. The N62B44 was evolved into the N62B48TU beginning in model year 2005. The N62B48 featured several changes over the N62B44, including an increase in the bore size to and stroke to which increased the displacement to 4798.52 cc. Several changes were made to the engine including different exhaust manifolds, replacement of the DIVA continuously variable length intake manifold to a DISA two-stage manifold, removal of secondary air injection ports and several small changes to accommodate the longer stroke crankshaft such as more traditional non-offset connecting rods and a deeper oil pan. It also featured different spark plugs, oxygen sensors, engine computer and inlet and exhaust valves with a stem diameter decreased to 5mm from 6mm. Applications: * 2005-2010
