From my perspective, the Q7 is a lot better looking than the frog-faced Cayenne, with a more domineering presence on the road.
I tested a V-8 Q7 priced at close to $60,000 on my Phoenix drive.

Audi says initial estimates put the Q7's fuel economy at 18 mpg in city driving and 21 mpg on the highway.
