So the big news is the big nose. Not often is such controversy caused by a plastic insert, but Audi's distinctive "waterfall" grille has proven to be a rather polarizing design choice, one which will eventually establish itself throughout the Audi line. Going beyond skin-deep, however, we find a thoroughly improved suspension, a less clinical interior, and all-new 255-hp V6, with the 4.2 from the A8 as an optional powerplant. As of right this instant, the sole transmission is an autobox. The 2005 A6 goes on sale in November for an estimated $45,000.
