audi says 420 Hp but on the dyno they make "only" 360 - 400 Hp......
And after an amount of using the "modern" FSI-technologie cokes the valves so the power can fall to 320/350 Hp. You have to use valve cleaners and so on but audi makes more money with changing the engines.
Good oil like 0W-40 or 5W-50 and short change intervalls are a must against coking.
But they seem solid cars otherwise, like the cossies.
