Motor Authority quotes a "reliable" source within Audi, who claims Audi will under-report the horsepower in its new RS6. Based on information from leaked chassis codes, official output will be 571 hp, bur actual output will be more than 600 horses. In fact, to be as exact as gossipingly possible, the dual-turbo V10 hyper-sedan will make 610 hp. This means... you all know what this means. Expect quarter-mile times to spin the earth backward, fuel consumption to make the US colonize Qatar, and a potential top speed (minus the governor) in the falling-from-space range. How do you say, "Suck on my tailpipe, M5" in German? [Motor Authority]
