A 3.2 litre VR6 engine weight 65 Kg more then a 2.0T FSI engine.
For example a Audi A3 2.0T FSI Quattro weight 1430 Kg and a Audi A3 3.2 Quattro 1495 Kg.
Audi want a sporty S3 there for a 3.2 or 3.6 litre VR6 is out of the question and it will get a 2.0 FSI K04 Turbo engine with 260 hp.
With a few more weight saving parts is will be a class of its own.
And futher Audi delivers the basics, tuners can do the rest, a chipt new S3 will go simpel past the 300 hp.
