Oh ... Here it is. Few days too early.
Nice to see Audi has leaks too.

OK ... A5.
Khmm ... A very shy attempt by Audi of "let's go a bit more exciting". After TT & R8 this one looks tame. Of course - it should. It is not small funky coupe like TT, or a super-car like R8.
Do I like it? Yes, and no. I can see a lot of "Bangle" elements in it. Concave-convex surfaces mixture (aka "flame surfacing") is very prominent here - more than on any other current Audi car. Also it follows E60 5er agenda of "I want to be boxy & round at the same time". Yet IMO 5er design is more cohesive while A5's (judged on pics only!) has very rectangular front & especially the rear. Eg. 5er rear while being boxy is smoothened by curvy rear lights, while Audi designers put rectangular clusters on rectangular rear - which ends up in very boxy appearence. This pic is just sad looking:
Front is interesting. I like more rectangular appearence yet it is not in harmony with the curvy side. Also the front fascia (grille, air intakes, headlights) is a bit too Audi-generic.
Side profile is best part of the car. Proportions are much improved. 20-something wheels make the car look smaller. Quite prominent reminiscence of last Audi Coupe. Although the rear from side view (rear lights + boot lid) looks a bit too Japanese-generic.
Interior - overall design is Audi-boring & leaves me cold. Yet fit&finish details are amazing, and Audi proved again they are masters of interior fit & finish!

I love the details - so missed by BMW - all that specially designed knobs, buttones levers etc. Eg. BMW still uses standard-generic rectangular button designs from 80s.

But they are getting better & better.
Conclusion: A5 is a fine car - I expected a bit more, but nice try.

More when I see the car in person.
