there was RS4 in 2007 and 08, the RS6 went out of production last year but they didnt bring any to North America, the RS5 is currently on sale in Europe and coming to NA in 2012. they are working on the all new RS6 but idk if they will offer it in NA, because not alot of people buy the S model and you expect the RS to have sales here? in NA all roads are limited to 60 or 70 mph while in Europe they have actual laws that you cant over take people from the right and the left lane only for over taking and if you see someone going faster than you then you must give up the left lane and let him pass. these laws are not inforce here so you only see losers and moms in a very slow vans driving very slow on the left lane while in Europe as i mentioned before, some roads are 80mph and some highways (Germany & Austria) dont have speed limit
