Mine tracks rock solid at 95mph+. (G05 50i M-Sport DHP, loaded, etc..) I have the 20” with RFT. I had the chance to do long distant higher speed cruising through a few states on two separate trips. I locked cruise in at 110mph for 10 minutes and didn’t have to touch the steering wheel with it making very little corrections on its own. 130mph feels like 65mph. Certainly the most solid feeling luxury rig I have taken on this trip. Better than my last A8 and other Audi’s.
Even when my wife took her turn to drive on long trips in “Eco mode” had no issues.
