The 3.2L and the 3.6L V6 FSI engines belong to
the VR family of engines. Their reduced V-angle,
compared with a traditional V-engine, gives them an
extremely compact and space-saving design.
The VR engines have a long history at Volkswagen.
The VR success began in 1992 with the start of
production of the 2.8L VR6 engine.

In 2002, the
VR6 was converted to four-valve technology.

In 2003
the capacity of the VR6 was increased to 3.2 liters,
resulting in a power increase of up to 250 hp. Then,
in 2006, the capacity was increased to 3.6 liters,
resulting in a power increase of up to 280 hp.

Special Features of both Engines:
Compact size
FSI direct gasoline injection
Four-valve technology with roller rocker arms
Internal exhaust gas recirculation
Single-piece variable-length intake manifold made
of plastic
Cast iron crankcase
Chain drive located on the transmission side with
integral drive for the high-pressure fuel pump
