I am considering a new A4 3.0 Tdi but I am also interested in the same engine in the Q7 since I may continue to track/trailer my Z4 M Coupe. I figure the mpg will be worse in the Q due to the extra weight but does anyone know actual numbers to compare the 2 vehicles? Also, how does this engine sound? I watched the video posted of the Q7 but can't really get a good idea thanks to the music. By the way, I'm in the U.S. so I know I've got a wait ahead of me.
Thanks in advance...
