BMW M62is anaturally aspiratedV8 petrol engine which was produced from 1995 to 2005.[1]A successor to theBMW M60,the M62 features an aluminium engine block[2]and a single row timing chain.[3]
In 1998, a Technical Update included VANOS (variable valve timing) for the intake camshafts.
The S62 engine is theBMW Mhigh performance version of the M62, which was released in theE39 M5,BMW Z8,Ascari KZ1,and theAscari A10.
Design
[edit]Like theBMW M60engine it replaced, the M62 is a DOHC engine withfour valves per cylinder,an aluminum block and aluminum heads. The M62 has fracture-split forged connecting rods,[4]hypereutectic pistons with ferrous coated side skirts. Most of the M62 engines usedAlusilfor the block material,[5]however some early M62 engines usedNikasilcylinder 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 aBosch Motronic 5.2engine control unit (also called "DME" )[8]and ahot wire MAF.[9]
Technical Update
[edit]In 1998, a "Technical Update" was applied to the M62, resulting in the M62TU variants. New features includesingle-VANOS(variable valve timing for the intake camshaft) andelectronic throttle control.The engine management was updated to Motronic ME7.2.[10][11]

Alpina F5
[edit]The F5 was Alpina's final iteration of the M62B44 engine, it featured all the same technology as the F4/1 but with an increased displacement due to an increased stroke thanks to a modified crankshaft. The increased stroke necessitated an oil pan with additional clearance as well as revised intake camshafts and exhaust camshafts from the M62B46 production engine.[31][32][33]It has a bore of 93 mm (3.7 in) and a stroke of 89 mm (3.5 in).
Applications:[18]

Successor | BMW S65 |
TheBMW S62engine (full model codeS62B50) is the high-performance variant of the M62, which is fitted to theE39 M5and theE52 Z8.The S62 was BMW's first V8 engine to havedouble-VANOS(variable valve timing on the intake and exhaust camshafts).[35]
The S62 engine produces 294 kW (400 PS; 394 hp) at 6600 rpm and 500 N⋅m (369 lb⋅ft) at 3800 rpm.[36]The redline is 7000 rpm.[37][38]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.[35]
Other differences compared to the M62 include:
- Individualthrottle bodiesfor each of the eight cylinders,[39]which areelectronically actuated[40]and have driver-selectable "normal" and "sport" mode throttle response.
- Compression ratiois 11.0:1, compared with 10.0:1 for the M62[41]
- A double-rowtiming chain,compared with the single-row chain used by the M62[42]
- Hollow camshafts.[35]
- Engine control unit is a Siemens MSS 52[35]
- Dual air intakes andmass flow sensors[43]
- A semi-dry sumpoil system, consisting of two additional scavenging pumps which activates during hard cornering[44][45]
Like the M62, the S62 has an aluminium block and head. The S62 was assembled atBMW's Dingolfing plant.[39]
