The interior is a big improvement over the outgoing model, as you'd expect. The current gen. dashboard has not aged well, at all. While the new one is a slim and streamlined design, which I really appreciate, it's still dizzyingly busy to me. This applies to the interior with the red accent lines. I hope it will look less so in person. The dark interior in the photos behind the link looks much better, IMO.
As for the exterior design, I feel that Audi is losing the edge they've held across the range the last couple of years. First the new TT and now the Q7 are showing a design language that I can't come to terms with. Looks too Americanized to me.
