Design
Like the
BMW M60 engine it replaced, the M62 is a DOHC engine with
four valves per cylinder, an aluminum block and aluminum heads. The M62 has fracture-split forged connecting rods, hypereutectic pistons with ferrous coated side skirts. Most of the M62 engines used
Alusil
Alusil as a hypereutectic aluminium- silicon alloy (EN AC-AlSi17Cu4Mg / EN AC-48100 or A390) contains approximately 78% aluminium and 17% silicon. This alloy was theoretically conceived in 1927 by Schweizer & Fehrenbach, of the Badener Metall-War ...
for the block material, however some early M62 engines used

Nikasil is a trademarked electrodeposited lipophilic nickel matrix silicon carbide coating for engine components, mainly piston engine cylinder liners.
Development
Nikasil was introduced by Mahle in 1967, and initially developed to allow Wankel ...
cylinder coating instead.
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") and a
hot wire MAF.
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
Electronic throttle control (ETC) is an automobile technology which electronically "connects" the accelerator pedal to the throttle, replacing a mechanical linkage. A typical ETC system consists of three major components: (i) an accelerator ped ...

S62
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).
The S62 engine produces at 6600 rpm and at 3800 rpm. The redline is 7000 rpm. The bore and stroke are and respectively. This results in a displacement of , compared with the of the largest M62 engine at the time.
Other differences compared to the M62 include:
* Individual
throttle bodies for each of the eight cylinders,
which are
electronically actuated and have driver-selectable "normal" and "sport" mode throttle response.
*
