2009 Audi RS6 Sedan Bows At Moscow Auto ShowEver since making every other wagon made look like a wimpy slow-mobile, the Audi RS6 Avant has had us drooling over its 580 HP, 5.0 liter V10. But now it comes in sedan flavor. The Audi RS6 sedan gets the same goods as the wagon (ceramic brakes, all-wheel drive, 100% badass) but cuts a more svelte shape thanks to the sedan form.

Expect to see The Audi RS6 embarrassing Ferraris at your local high-dollar drag strip as soon as they hit dealer lots. [Autoblog]
