Set to arrive in November, the 2007 Audi S6 uses a mighty 435-horsepower V10 to get noticed on the street, yet steers clear of appearing obnoxious with only subtle design cues, including beefy 19-inch alloys and strategically placed badges. As such, the S6 has a powerful presence, yet not so much that it will make Junior wet himself in fear upon first sight. No, outlandish and intimidating design are not what mark the S6, rather it’s that V10 engine coupled with Audi’s respected quattro all-wheel-drive system, both of which work in concert to greet 60 mph in only 5.1 seconds.
