And thats why audi brought them, and out came the RS4 engine along with theyre expertise in some of the other engines too. RS4 most notably though
The 2.0T comes with forged pistons as stock
LOL firstly those tuner cars are assisted via a turbo, hell most turbo cars go way over 100hp/liter. So no its not impressive at all. However we are talking stock NA here, and that is impressive, especially from the RS4 unit as 90% of the torque is availabe at 2250rpm, unlike most other NA 100hp/liter which need to be in high revs to get the best out of them.
Seriously though 1000hp is nothing, if your still impressed by that, well then I suppose it will still be a few years untill you see the light. Anyone with enough money can get 1000hp out of nearly any engine, but the things that dont get tested in those magazines is reliability and the power curves for every day driveability.
Back in the 80's bmw got 1500hp out of a 1.5 litre engine. Audi developed a 2.2litre 5 cylinder 1000hp engine for theyre Ur Quattro rally car. That is impressive, and if you think that it doesnt require alot more skill to get big power out of a small engine, than it does with a big engine your sadly mistaken.
So I have to question your knoweldge of cars as 1000hp has been done, over and over and over and over. Quite frankly im bored to death by it.
