Audi Rolls Its 10 Millionth Midsize Car Off Production Line

INGOLSTADT, Germany — Audi is basking in its midsize class success, as it watched its 10 millionth midsize car roll off the production assembly line in early October.

A Misano Red Audi S4 with a black and alabaster-white interior and a 333-horsepower V6 engine was the lucky car to represent four generations of both the Audi 80 and Audi A4 since 1972.

Audi has long considered its midsize vehicles the heart of the brand, said Frank Dreves, board member for production at Audi AG, in a statement. "Thanks to its sophisticated technology and excellent quality, the Audi A4 is our best-seller — winning over customers in every market since it was launched," he said.

Audi has been producing the A4 model family at its Ingolstadt site since 1994 and, since 2007, in Neckarsulm, Germany, as well.

The face-lifted 2013 A4 sedan and wagon arrive in the U.S. next year, along with the S4 and A4 Allroad.

The updated A4 and S4 are being unveiled this week in Germany.

Inside Line says: Audi understands that longevity in this competitive arena is something to celebrate.
