1998 Audi A6 Quattro Audi's new center of gravity. By Paul A. Eisenstein, New Car Test Drive .com

Audi officials are calling the fantastic new A6 their "center of gravity." Audi's sales have taken off the

past couple years and the company's new luxury sedan is certain to keep that momentum going.

Indeed, Audi is here to stay.

We hated to give our A6 back to them. We loved its elegant looks and friendly interior. We enjoyed its brisk

performance. We appreciated its outstanding performance in bad weather. The week we spent in it seemed way too short.
