Audi's A4 outsells all other premium sedans in Germany

Though overall sales figures have slumped through the end of 2008 and start of 2009, there are occasional bright patches of news as carmakers grab market share from long-time competitors or reach individual sales records. Audi has done just that, beating BMW's 3-series and Mercedes-Benz's C-Class in its home market for the year. The rivalry between Audi and its German colleagues is deep, and though the brand doesn't sell as well in the U.S. in relation to BMW and Mercedes, its success in its home market serves to prove how fierce the competition is.
