Technical data

The 3.2l V6 petrol engine

is an advancement of the Volkswagen 2.8l V6

engine. The construction principle of applying a

narrow V-angle of 15°, and its associated advan-

tages resulting in a low overall length and width,

has been adhered to. The displacement increase

to 3.2l, in conjunction with its first-ever longitudi-

nal mounting in a vehicle, required a complete

overhaul of the engine. The engine's increased

displacement was rendered possible by extend-

ing the piston stroke while simultaneously aug-

menting the cylinder bores.
