Audi loaned us a $110,170 version of the S8, and that sum included a $1,700 gas guzzler charge and a $720 destination fee. Painted Daytona Gray Pearl Effect, our car added to the $92,000 base price a wonderful Bang & Olufsen audio system ($6,300); a leather appointment upgrade that coated the dash with stitched hides ($4,900); and a Premium Package with features like keyless ignition and locking, heated rear seats, an advanced parking system, a power rear sunshade, and power assists for the trunk and doors ($3,500). We also had Sirius satellite radio ($550) and carbon fiber trim ($500). We spent a week driving the Audi S8 on the highways and byways of the Los Angeles area.
