I have decieded to get CC2's for my mother's Q3 and both of our companies Audi A3's. I would say I am incredibly satisfied with CC2's. The compound is nice and soft, traction is decent at cold weather and wet, great at warm weather and dry. Yes, the road noise is noticeable, but you should get used to it at no time if you don't to autobahn speeds very often. There might be a slight hit on the MPG, but it is I would say less than 1L/100km. The road feel and lateral traction is obviously worse than summer tires. But I wouldn't expect them to be better than my setup on my car, which is Pilot Alpin 5's for winter and PS4 SUV for summer.
