I've been in a 1.4tfsi Sport A4 since March. I find it very pleasant indeed, it's quick enough, very quiet engine and wind noise, but because of this you do tend to focus on the road noise which is not as well suppressed. I put this down to British road surfaces as a drive to Barcelona via the French Autoroutes and Spanish Autopistas was a revelation; there was no road roar at all, just a faint swish. It does have one issue - not a problem but you have to adapt a bit - at very low revs the power suddenly disappears. So in a multistory car park where you could normally climb the ramp at about 1200rpm in second gear it won't pull, but dies and requires first gear, put a few more revs on and by 1500rpm it's has so much torque it can pull strongly in sixth. It has very long gearing which I like as it makes cruising so relaxed but does mean you effectively have 3 overdrive gears. Top speed is 130mph, but the theoretical speeds if it could hit the redline in 4th, 5th and 6th are approximately 140, 180 and 210. My MPG is in the high 40's long term, and on the motorway I stick to the limit and can nudge it up to about 61mpg if I drive. With the cruise control it's a bit lower.
