The BMW N62 is a naturally aspirated DOHC V8 engine which was produced from 2002–2010. It is the world's first engine to use a continuously variable-length intake manifold,[1][2] and BMW's first V8 to feature variable valve lift (Valvetronic) [3][4][5]

Compared with its M62 predecessor, the N62 also has variable valve timing on both the intake and exhaust camshafts (double-VANOS).[6] As per the M62, the N62 has 4 valves per cylinder, an aluminium block, an aluminium head and fracture-split forged powdered metal connecting rods. The redline is 6500 rpm.[citation needed] 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 won overall as well as claiming the "Best New Engine" and "Above 4-litre" categories.[7]
