So after owning the Q7 for two weeks...here are my first impressions (note that some of these impressions are somewhat in comparison to our 4Runner since that was our last vehicle):
Pros:
1) Build quality is superb (as would be expected for a vehicle that had an MSRP of $62k)
2) MPG is incredible. Averaged just over 27mpg for our mountain trip (there and back and the driving while up there ~500miles). That was with a skybox and crossbars installed the whole time. I took it to work again yesterday and managed 37.8mpg on my commute home (see pic). This is a nearly 5500lb AWD vehicle. We didn't buy it for the mileage, but it has been the icing on the cake.
3) 406 ft/lb makes this vehicle feel much sprightlier around town than it has the right to be. Forced induction is a huge boon at elevation.
3) handling/steering feel is phenomenal in relation to other vehicles its size (no, it is not a Miata). Have way more confidence on mountain roads.
4) Tech is great. Bose speakers are better than I was expecting (although are not as good as the B&O speakers from previous Audi).
5) Seating is very comfortable. For whatever reason, Audi seats fit my wife and I well. Probably part of the reason we have been Audi fans. When we switched from an Audi to the 4Runner, we remember not liking the 4Runner seats after long trips...and our trip to the mountains last weekend backed that up as we had zero seat fatigue after our first road trip with the Q7.
6) People space is a huge improvement vs. the 4Runner (although falls short of something like a Honda Pilot). Storage space is actually worse than 4Runner due to high shelf and sloping design (even though length makes up for it a bit).
Cons:
1) There is more turbo lag than I would like. It is way better than the lag in my friends X5 diesel, but it is still there. I am getting used to it though and it is becoming less and less of a complaint.
2) Engine runs out of breath at high speeds. So high speed passing maneuvers are not nearly as punchy as pulling from a start or lower speeds. Minor gripe though as it spanks the 4Runner in the mountain 99% of the time even though it is 600lb heavier.
3) ride is a bit stiff for the terrible roads that we have in Colorado. I imagine off-roading in this thing will definitely be less enjoyable from a comfort perspective (the 4Runner swallowed nasty stuff quite well).
Random comment...this thing was not specced with the tow package...so no hitch...ON A DIESEL. Are you kidding? Should just come standard with Diesel version of this vehicle. Called up local dealer and they wanted $1900 to Install OEM hitch/control module. Haha...yeah right. Bought setup for $840 on Amazon w/ shipping and have it waiting in my garage to install. That is still a bit much for a hitch...but that is what you expect from an Audi OEM part.
