Downsizing? What downsizing? While rivals may be replacing cylinders with turbochargers – heck, even Audi itself has done that with the twin-turbo V8 succeeding the V10 in the S8 and such – the new RS4 is reportedly on its way in full-fat 4.2-liter V8 FSI trim.

The report comes courtesy of AMAG, the importer for Audi in Switzerland, which has confirmed that the RS4 Avant (oft spied in prototype guise) is scheduled to debut at the 2012 Geneva Motor Show this coming March. Along with it, we're told to expect a series of new TSFI engines and an upgraded TT-RS with 360 horses.

As for the RS4 Avant, we're looking at 450 horsepower with all-wheel drive and enough cargo capacity to make any luxury crossover buyer reconsider (much like the S4 Avant pictured above, only more so). That is, buyers in Europe, anyway, as we're not expecting the RS4 to make the trek across the Atlantic.
