BMW N62#H1

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 4.4L has a bore of {{convert|92|mm|in|abbr=on}} and stroke of {{convert|82.7|mm|in|abbr=on}} for a total displacement of 4,398cc and features double-VANOS variable valve timing on both the intake and exhaust camshafts (the M62 features variable valve timing on only the intake camshaft).{{cite web|title=BMW N62 V8 Engine|url=http://www.unixnerd.demon.co.uk/n62.html|website=www.unixnerd.demon.co.uk|access-date=1 July 2017|archive-date=17 January 2020|archive-url=https://web.archive.org/web/20200117170511/http://www.unixnerd.demon.co.uk/n62.html|url-status=dead}} As per the M62, the N62 has double overhead camshafts (DOHC) with four valves per cylinder, an aluminium engine block and an aluminium cylinder head. The N62 4.4 featured offset fracture-split forged powdered metal connecting rods and 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.{{cite web|title=BMW N62 V8 Technical Information|url=https://www.internetsomething.com/lpg/01_N62%20Engine.pdf|website=www.internetsomething.com|access-date=16 November 2022}} 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, for certain cold start conditions and to maintain a set amount of vacuum in the intake during low load conditions such as cruising on the highway or idling. The vacuum pump mounted on the bank 1 cylinder head only supplies the brake booster and certain auxiliaries with vacuum, making the use of the standard TB for manifold vacuum control a requirement for proper functioning of the crankcase ventilation system as well as the fuel evap valve and other emissions related systems.{{cite web|title=BMW N62 V8 Technical Information|url=https://www.internetsomething.com/lpg/01_N62%20Engine.pdf|website=www.internetsomething.com|access-date=16 November 2022}}

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 RPM and is progressively shortened until it reaches its shortest length at the engine's redline. This maximizes torque throughout the RPM range, producing a much broader torque curve and more peak HP.

Applications:

• 2004-2005 BMW 5 Series (E60) 545i
• 2004-2005 BMW 6 Series (E63) 645Ci
• 2001-2004 BMW 7 Series (E65) 745i/745Li
• 2004-2006 BMW X5 (E53) X5 4.4i and 4.8is

The N62B48 engine used in the E53 X5 4.8is was a 4.8L variant of the N62B44 which was accomplished by way of an increased bore size to {{convert|93|mm|in|abbr=on}} and stroke to {{convert|88.3|mm|in|abbr=on}} which increased the displacement to 4798.52 cc. The N62B48 in the E53 shared other components with the N62B44 including the DIVA intake which was replaced when the engine was evolved to the N62TU. The oil pan was modified and deepened to account for the longer stroke crankshaft, this change was applied to all N62's in October 2003 which includes the 4.4 variants in production at the time. Other changes were also made to accommodate the longer stroke crankshaft such as more traditional non-offset connecting rods.

The N62 was evolved into the N62TU beginning in model year 2005 and the 4.4 was replaced with the 4.8 variant by using the same bore and stroke from the 4.8 version in the E53 4.8is.{{cite web|title=BMW N62 V8 Technical Information|url= https://www.e90post.com/forums/attachment.php?attachmentid=1584162&d=1488747521|website=www.E90post.com|access-date=16 November 2022}} The N62TU featured several changes over the N62B44, including different exhaust manifolds, improved catalytic converters, new pre-cat oxygen sensors, new MAF, updated engine management unit, replacement of the DIVA continuously variable length intake manifold to a DISA two-stage manifold, removal of secondary air injection ports and different heads to accommodate this change and the increased bore, different spark plugs and inlet and exhaust valves with a stem diameter decreased to 5mm from 6mm.
