With not an M, AMG or RS in sight.
Cars have become a lot more powerful in recent years, but they've also gotten much heavier at the same time. So for some, especially drag racers, it is often seen as easier to pump big horsepower numbers out of older cars. You'll see this in the US plenty, but it's done all over, and the following video shows a couple of the better examples from Germany. One of the cars is a Mk I VW Golf which has been converted to AWD.
The other car is an Audi 90 that came from the factory with AWD, but which has still been made quite a bit more powerful.
