Yepp, I truly believe you guys can get 27-32 on the highway, as most of you have 5 and 6 speed trannys. I was saying in a different thread that if the trannys in the auto C4s like mine would have 5/6 speed trannys probably would also get around 30 mpg as well.
There's no way though someone gets 27 mpg on mostly city driving ("littered with traffic lights") with these Audis :) . Maybe if it was a Jetta TDI, or you catch all the time the lights on green "chain", then...

the temperture is always in the middle and i have new air filter in there. on the highway is good i did few long trips and i get about 450 on the full tank. and that crusing between 70-80 mph
