Here is this revised or updated Audi A4 for your consideration. I have marked in red all the areas that look identical with the outgoing car.
I conclude the glasshouse is the same and the bodysides to halfway down the doors are the same geometry. They have replaced the pronounced upward curving swoosh groove with a scalloped indent and the lower bumpers have been tweaked. There’s nothing wrong with this as such. It is however what looks incredibly like a mild facelift. It is not a new car.
