I've got a 2012 B5 with 3,333.3 and I usually get 60 or just below. My average freeway commute is 10 miles there and back again with a top speed of 70, but usually 65. Sadly, I weigh in at 195 and can't seem to lose more. That's what I call a light weight!
Perhaps that's why my city MPG is so disappointing in stop-and-go NYC traffic -- because of the traffic pattern I'm either over-revving in 1st gear or on the verge of lugging in 2nd gear practically all the time.
