We knew a production version of the Audi A3 sedan will be brought onto the market right after the A3 Concept sedan has been unveiled at the 2011 Geneva Motor Show. Of course today we finally have the proof: the model has been caught during cold winter testings.

The sedan version of the will be built on Volkswagen Group’s flexible MQB platform, which will make the model significantly lighter than the current hatchback version. Under the hood we will see the same engine as in the rest of the A3->ke1086 lineup, but rumors suggested that the 408 horsepower 2.5-liter five-cylinder engine found in the concept will also be offered.

The new Audi A3 sedan will go on sale on the US market at the end of 2013. It will also be offered on markets like China and Europe and will target models like Mercedes CLA and the previously rumored four-door version of the BMW 1-Series->ke313.
