I noticed that an updated brochure has finally been published including the S4 and had a leaf through. This explains why two different power figures have kept appearing in the press: the saloon has 354 but for some reason the Avant only has 340. Anybody know why the Avant has been down-rated slightly? I've never seen this before from Audi.

Overall it strikes me as a lot of extra money for a very small performance increase over the 3.0TDI, different seats and a few extra badges. I guess that they're banking on the fact that some people just don't like diesel...
