I suppose if I hadn't previously been in an Audi before my 2017, I'd never notice but wondering what they changed? I'm coming from a 2015 A6 Premium Plus Quattro to a 2017 A6 Premium Plus S Line Quattro...both 2.0T. I assumed just about everything, save for some minor appearance details (S Line Pkg, C7.5 facelift, etc). They both have the 8 speed tiptronic, but the tranny seems to maybe have a torque converter now? Excuse my ignorance on these trannies. All I know that the 2015 used to stay put on an incline if I chose not to accelerate. This sucker now rolls back as if in neutral. Feels like my old Nova and Chevelle.

What gives?
