INTRODUCTION:
The M62 engine series replaces the M60 engine. The M62 engine is a consistent further development of the BMW V-8 cylinder engine series introduced in 1992. As of 1/96 it will be installed in the series E31, E38 and E39 over a staggered period of time.

The new M62 engine is based on the M60 engine with regard to its essential features:

- 8-cylinder V-engine

- Cylinder arrangement 90°

- 2 four-valve cylinder heads

- Light alloy design

The most important objectives of the further development were compliance with new legal stipulations and improvement of comfort and quality.

Particular attention was paid to the following features:

- Reduction of fuel consumption

- Rounder/fuller torque curves (for improved vehicle elasticity)

- Optimization of engine acoustic and comfort characteristics

- Compliance with new exhaust emission regulations (AEU-2) as well as the expected on-board diagnosis (OBD II) requirements in the USA.

Essentially, these objectives were realized by increasing the engine capacity, modifications to the crank drive, modifications to the camshaft drive, further development of various engine components as well as by implementing the new digital motor electronics DME M5.2.
