Character (shoulder line) is a total disappointment. I expected a more prominent one (eg in an A3-sedan style). At least the lower character line is a bit more 3D now. OK, they also made the grille, headlights and the rear lights a bit sharper looking ... but that's it. Overall it's TOO evolutionary. Even for Audi. C'mon, even Q7 is more different from its predecessor!
Interior ... predictable after Q7 debut. That's obviously THE design theme & layout for contemporary non-sports Audi cars. It looks neat & tech-ish ... But modern? I don't think so. That "air vent" styling element across the dash looks already dated to me ... Even more: it was initially used in VW cars (Passat!). C'mon! And it's not particularly original either: Mazda 2 & CX-3 also feature similar styling element.
It's also a strong contrast between exterior & interior: the interior is cool, modern, tech-ish ... the exterior is not (enough) ... although sharp, it's also utterly unimaginative and too conservative. Eg. Jaguar & Range Rover & Volvo works are much better & consistent: combining modernity of exterior & interior well. The only Audi model that could pull that off is A7.
I don't know ... I expected more from this new A4. I don't know what's going on in the Audi Design Dept. (all sudden personnel changes; all sudden design strategy changes etc) but I guess they are in limbo. I hope they produce something spectacular soon - based on the Prologue Concept. A8 or A7 could be real winners in the looks department (if featuring much of Prologue style & design).
This A4 ... (just like Q7) ... it looks OK, not ugly ... but as said: boring as hell.
