The Skoda loving Swedes over at Bilfeber caught a completely undisguised 2009 Audi RS6 Sedan undergoing winter testing in the frozen north. This is the first time we've seen the 580bhp twin turbocharged V10 TFSI engine without a station wagon on its back. Clearly visible are the RS2-style fender flares in addition to R8-influenced lower air intakes. RS6 badging is prevalent on both the interior and exterior. Our favorite part is the roof rack mounted spotlights, although sadly those probably won't reach production.
