Drive Units - Volkswagen Passat W8 Service Manual

The W8 engine in general
The Passat W8 is fitted with one engine, the new
W engine generation, the W8. The W layout is
obtained by joining two V engines at an angle
of 72°. This layout achieves a very compact
8-cylinder engine with very small dimensions.
Compared with other 8-cylinder engines, the W8
is very lightweight due to the short size and
through the use of aluminium, slim conrods and
short pistons.
For more details, refer to Self-Study Programme No. 248.
Four valves per cylinder, low-friction roller rocker
fingers, chain drive for the four overhead
camshafts with camshaft timing adjuster are
some of the noticeable features of this modern
engine.
