I got to drive the R8 and RS6 around Sears Point in northern California about six months ago and the R8 was really easy to drive and very forgiving when driven at 7/10th of it's full potential. I don't know if Audi still offers The Audi Experience but for $600 you get to drive all the Audi models around cones in the parking lot. There were Audi TTs and A8s and even their Q7(?) SUV. Then the highlight of the day is you get to drive both the RS6 and R8 on the track following an instructor at speeds up to 130 on the straights and the slowest was a hairpin taken at 60mph. Three laps each per car driving but there are two drivers per car so you get to ride as a passenger too.
