Did Audi cancel the plan to rename the ICE A6 as A7?

Yes, Audi officially reversed its naming strategy; the internal combustion model remains the A6 TFSI. For buyers considering the Audi A6, that matters because it affects how easy the car is to live with, whether for commuting, family use, long-distance driving or ownership costs. The useful way to read this is not as an isolated specification, but as a clue to how the car will feel in real daily use.
