All of the major traits from the concept are present on the production model, including that massive, oversized grille and aggressive roofline. In fact, the entire front end appears to carry over from the Q8 concept, just toned down a few notches. The stainless steel accents on the air intakes are gone, and the headlights, though similar in shape, look more traditional than those on the concept. The small cutouts between the grille and the hood look to be gone as well.
Around the side, we can see that the concept's sharply angled rear window and sloping roof have are present, mostly unmodified. The Q8's beltline doesn't appear quite as high as the concept's, but the windows look to be the same relative shape. The big creases above the wheel arches have been reduced slightly. Also, although the Q7 and Q8 will share a platform and therefore a wheelbase, the Q8 is slightly shorter overall. The smaller front and rear overhangs, combined with the tight roofline, give it a high-riding hatchback profile, similar to the Porsche Macan.
The changes between the concept and production model are most evident around back. The bumper mounted exhaust pipes have been dropped, at least on this version. The upright vents on the outside of the tail lights have also been dropped. The camouflage around the rear is heavy, so it's difficult to to say how much of the body-width tail light carries over, though the light itself seems to shine through in the same shape.
No word on when we'll see a production version, but expect to see the Q8 concept around for a few more shows. Look for more details on the engine, including whether or not the plug-in hybrid powertrain carries over from the concept, closer to the full reveal.
