Our friends over at CarMagazine have caught the Audi RS6 doing high-speed testing at the Nurburgring. The Audi RS6 is expected to be powered by a 5.2 liter V10 engine that produces 530 horsepower, well over BMW M5′s 500 horses and Mercedes E63 estate’s 514 horsepower.

The Audi RS6 Avant will have ability to do 0-62 mph in 4.5 seconds with a top speed of 155mph. The car is made fully by Audi’s Quattro division and, according to CarMagazine, should cost somewhere around £67,000.
