I have driven both the new V10 S6 and the RS6. The new S6 is a great car. To me it feels like driving the RS6 except it never turbo lags. I think the only thing that makes the RS6 feel faster is that fact you feel it building boost.

The S6 dosent feel that spectacular till you look at the speedo. I stepped on it and didnt think much of it, then looked down and realized how fast I was going already. Its no screamer, but its a great/fun car.

 

Wheels arent that bad, I test drove the S8 this summer sounds amazing but its somewhat slow off the line compared with the M5 e60, E55K and E63

 

OMG I drove it yesterday and absolutely loved it! The seats and ergonomics are definitly the best of any sedan in that class that I have driven..... so nice! Agree on the wheels, not much of a fan but those can be fixed with some hot HRE's.

As far as leasing goes. The car is using standard Audi rates with a 53% residual at 36 months.
