The BMW N62 is a naturally aspirated V8 petrol engine which was used in BMW cars from 2001–2010. It also remained in small-scale production for the Morgan Aero until 2019.[1] The N62 is the world's first engine to use a continuously variable-length intake manifold,[2] and BMW's first V8 to feature variable valve lift (called Valvetronic).[3][4][5]
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.[6]
Design
Compared with its M62 predecessor, the N62 also has double-VANOS (variable valve timing on both the intake and exhaust camshafts).[7] 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 fracture-split forged powdered metal connecting rods. The redline is 6500 rpm.[4]
