Chronology
Predecessor	BMW M60

In 1998, a Technical Update included VANOS (variable valve timing) for the intake camshafts.

The S62 engine is the BMW M high performance version of the M62, which was released in the E39 M5.

Design

Like the BMW M60 engine it replaced, the M62 is a DOHC engine with four valves per cylinder, an aluminium block and aluminium heads. The M62 has fracture-split forged connecting rods,[4] hypereutectic pistons with ferrous coated side skirts. Most of the M62 engines used Alusil for the block material,[5] however some early M62 engines used Nikasil cylinder coating instead.[6][7]

Alusil technology integrates silicon throughout the aluminum cast so that liners or treated bores within this block family are not needed.

The M62 uses a Bosch Motronic 5.2 engine control unit (also called "DME")[8] and a hot wire MAF.[9]

Technical Update

In 1998, a "Technical Update" was applied to the M62, resulting in the M62TU variants. New features include single-VANOS (variable valve timing for the intake camshaft) and electronic throttle control. The engine management was updated to Motronic ME7.2.[10][11]

The BMW S62 engine (full model code S62B50) is the high-performance variant of the M62, which is fitted to the E39 M5 and the E52 Z8. The S62 was BMW's first V8 engine to have double-VANOS (variable valve timing on the intake and exhaust camshafts).[27]

The S62 engine produces 294 kW (394 hp) at 6600 rpm and 500 N⋅m (369 lb⋅ft) at 3800 rpm.[28] The redline is 7000 rpm.[29][30] The bore and stroke are 94 mm (3.7 in) and 89 mm (3.5 in) respectively. This results in a displacement of 4,941 cc (301.5 cu in), compared with the 4,398 cc (268.4 cu in) of the largest M62 engine at the time.[27]

Other differences compared to the M62 include:

• Individual throttle bodies for each of the eight cylinders,[31] which are electronically actuated[32] and have driver-selectable "normal" and "sport" mode throttle response.
• Compression ratio is 11.0:1, compared with 10.0:1 for the M62[33]
• A double-row timing chain, compared with the single-row chain used by the M62[34]
• Hollow camshafts.[27]
• Engine control unit is a Siemens MSS 52[27]
• Dual air intakes and mass flow sensors[35]
• A semi-dry sump oil system, consisting of two additional scavenging pumps which activates during hard cornering[36][37]

As per the M62, the S62 has an aluminium block and head. The S62 was assembled at BMW's Dingolfing plant.[31]
