2007 Audi S8 in Allison Park

The previous S8, sold in the States from 2001 to 2003, challenged all but the most dedicated Audi spotter, as its visual giveaways were limited to a slightly lower ride height; eighteen-inch wheels; and silver side mirrors. The new S8, by contrast, stands out from the current A8 in myriad ways. A series of vertical bars has been added to its grille, added just months before the design was finalized.
