Markus 197mph is indeed 317 km/h....
The Autobahn in question is the 46. It runs parallel to the 44 (Aachen - Dusseldorf). It was a 2 lane stretch and it was pretty deserted.

The car generates 300lbs of downforce at 130mph. At 200mph it was glued to the road.
It feld so much different from a 911....
When we were planning the 200mph chase over dinner the night before I was a little nervous...
It's kinda silly... But then the next morning I gradually built it up from 160 to 180 and the car felt incredibly solid....
From 180 to 200 it was quick. Again I was in 5th with 500 rpms to spare and another gear...
Stock (my car is completely stock) the car has been tested at 212mph on the 8mile oval in Nardo' (Italy).
In all honesty I didn't pay attention to the engine noise or anything for that matter.
I didn't even know how fast we were going until my friend told me.
My arm muscles were aching and my mouth was completely dry after those 8 mins at 180mph...
I do not think I will do it again.... one because you need a friend totell you how fast you are going, two because you need an empty stretch of Autobahn, three because it is really a bit silly...
Still it is one of those things you just hear about and read in the magazines...
... and I nearly got there... The fact that we did "only" 197 makes it even more real....
