Re: What is the real life mpg difference between 2.8Q12V an 2.8Q30V?
In my '92 100CS with fwd and 5-speed manual tranny, I regularly got between 20 and 23 mpg with an occasional peak at 24 mpg.
My '99 A6 with quattro and tiptronic runs between 18 and 20 mpg, with record so far of 20.9 mpg.
The biggest issue, though, is the loss of fuel tank capacity. The C4 has/had a 21 gallon tank, the C5 only 18.5 gallons. Whereas I would generally fill up the 100CS at around the 400 mile mark, the C5 gets anxious at around 300.

Apples and oranges- 30V has a 5 speed auto, 12V has 4 speed auto....
Our '93 would run 700-800 rpms more at 80mph than the '98 30V. As a result, our highway mileage in the '98 has been in the 22-24 range, while the '93 would do 21-22 at best.
At 65 mph, the cars were nearly identical.
In daily commuting, the '93 actually did a bit better and even felt more responsive away from a light. but the differences in mileage were still too close (16-18 for both) to say one was any better.
Interestingly, the new allroad with twin turbo, 250hp is getting better commuting mileage than either of the other cars.
