Hi. I've gone the other way, A4 40Tfsi to Q5 45Tfsi. I found that around town, I would get high 20's & into low 30's in the A4. On the open road, on a decent run & not caning it, I could get mid to high 40's quite easily. I did see 50+ on a few occasions, but that was quite rare. Significantly better than the Q5, although I have seen just over 40 from the Q5 once or twice.
