BMW M62


The BMW M62 is a naturally aspirated V8 petrol engine which was produced from 1995 to 2005. A successor to the BMW M60, the M62 features an aluminium engine block and a single row timing chain.
In 1998, a Technical Update included VANOS 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, hypereutectic pistons with ferrous coated side skirts. Most of the M62 engines used Alusil for the block material, however some early M62 engines used Nikasil 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 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 and electronic throttle control. The engine management was updated to Motronic ME7.2.
