The Audi A4 is roomy for its class and efficiency. It's no wonder that Audi has managed produce its five-millionth A4 at its Ingolstadt plant, in Misano Red. The model comes as a wagon or sedan, plus available Quattro all-wheel-drive, an S variant and a CUV-ish Allroad model that isn't sold in the States. Frank Dreves, Member of the Board of Management at Audi, calls A4 number five million as another major milestone in Audi's history.
