I also have a 2010 CTS-V with a manual tranny. If I'm not mistaken, the A6 has a higher gas guzzler tax than the 6MN in the U.S... ($2600 vs. $1300 for the manual while the auto is a no-cost option in the U.S). In Canada, we pay a $400 "green tax" on all Vs, but the auto is a $1700 option here.

I get approx. the same fuel mileage numbers with my V when converting to the U.S. gal and that's at about 72-73 mph with the A/C on. Again, if speculation is correct and the Z comes in a couple of hundred lbs. less than the V. I'd also suspect mileage wouldn't be any worse.
The other "unknown" would be the gearing, which obviously is still speculation.

FWIW, the auto V has a 3.23 rear end with transmission ratios being:
1st 4.02
2nd 2.36
3rd 1.53
4th 1.15
5th 0.85
6th 0.67

Top speed in the auto is limited to 175 mph because the engineers feel the speed of the output shaft needs to be regulated. (manual Vs are not limited and will hit 191 mph.

The manual V has a 3.73 final drive with a dual disc clutch (an absolute joy to drive!!) and gear ratios as follows:

1st 2.66
2nd 1.78
3rd 1.30
4th 1.00
5th 0.80
6th 0.63

You can expect fuel mileage numbers to drop noticeably in the colder weather, along with traction (while the power will noticeably increase!) and of course, with power like that, it's a HUGE challenge just to keep your foot out of it!! LOL!
Hope this helps...

Best regards,

Elie
