Now in its 8th generation, the A4 has become Audi’s best-selling model. In almost 40 years, Audi has sold almost 10 million units of the A4 and its predecessor the Audi 80. Now the carmaker presents a massively revamped A4 series. The design is even bolder. The horizontal lines at the front are more pronounced, and the bulge in the hood is more prominent. The revamped engines are said to consume up to 11% less fuel. Together, the sedan and Avant wagon models offer a choice of six TDI and four diesel versions. Drive it! tests the new A4 sedan powered by a 2.0-liter TFSI engine. For more go to http://www.dw.de/dw/0,,9690,00.html
