BMW M62

The BMW M62 was a naturally aspirated V8 petrol engine built from 1995 to 2005 as the successor to the M60. Like its predecessor it has double overhead camshafts, four valves per cylinder and an aluminium block and heads, but it uses a single-row timing chain, fracture-split forged connecting rods and a Bosch Motronic 5.2 control unit. Most blocks use Alusil, which carries silicon throughout the casting so no liners or bore treatments are needed, although some early engines used a Nikasil bore coating. A 1998 technical update, the M62TU, added single-VANOS variable valve timing on the intake camshafts and electronic throttle control. The 3.5 and 4.4 litre versions powered the E39 5 Series, the E38 7 Series and the E31 840Ci, and the S62 was a high-performance version for the E39 M5 and the Z8.
