I've had a few Audi S models and the only one that rode well as the S8 (because it has air suspension), all the rest were hard to the point of being annoying, I had an S6 at the same time as my 612 and the 612 rode better at speed.

 

The RS7 looks like one hell of a car on paper and in photos. If it drives as good as it looks, it's going to clean up!

 

Not a big fan of the interior photos I've seen thus far Outside is beautiful (minus the Quattro on the grill).
