The C6 A6 platform uses a 6-speed Tiptronic tranny, not a 7-speed (USA models). If you visit...
the C6 forum, you'll see that posters there are reporting mileage as high as 30+ MPG on the highway with the 3.2L FSI V6, much better than our 12V 2.8L V6 with a 4-speed auto tranny in the C4 platform.

Are you sure?...
The difference in rolling circumference between 195/65/15 (stock size) and 205/65/15 is only 2%. If stock size is 3400 at 75mph then a 2% larger tire would be 3332 rpm. With the gearing we have here in the U.S. even a 225/65/16 would only bring 3400 @ 75mph down to 3088.
Do you know the rpms at 75 mph with the stock size 195/65/15 tires? I wonder if the gearing is different. Manual or auto transmission?

Re: Are you sure?...
I have an auto. The gearing must be different because the manual turn at 2800 at 75. ours are FWD
That must explain the great fuel mileage I got that nobody would believe
