In Germany, the Audi A4 was purchased more often than a BMW 3-Series. Audi's A6 and TT models also topped their market segments for 2008.

The Audi A4 is not only Audi's top selling vehicle, it was also purchased more often in Germany than the BMW 3-Series. 2008 figures for the A4 have been released, with over 98,714 units in Germany. The Audi A6 and Audi TT also topped their segment, with 45,304 and 10,630 vehicle registrations, according to the company.

Audi claims the A4 was second only to the Volkswagen Golf in terms of overall sales in Germany. Both brands are owned by VW. The figures also show a great boost for Audi, with increased sales in Germany, and all of Western Europe. Audi Chairman Rupert Stadler said, "Audi is presently experiencing stronger growth than any other premium brand in the region - and thanks to new models we will maintain this dynamism."

"In a difficult market environment, we want to further expand our market share in Germany and Western Europe."

The 2009 model year Audi A4 was released in April 2008. The '09 S4 Sedan and Avant arrive in European dealerships this quarter.

Not a bad birthday present for Audi's 100-year anniversary. Audi sold more than one million vehicles worldwide last year. BMW still leads them as the global luxury brand, having sold 1.12 million in 2008.
