If you haven't experienced the Autobahn, here's a little vicarious ride for you. This was me on the way to Hamburg in an Audi TT! 140 MPH! In Germany it's illegal to hang in the left lane.

Looks like a thrill. I've had the good fortune to spend some time on Germany's autobahns for several days on two separate trips to the country. The first time I was driving a BMW 318d so it wasn't capable of hitting the speeds you did in the video. I believe it maxed out at 130 MPH. Later I had one of the mid-level turbodiesel Audi A6 models and managed to get up to about 143 MPH.
Diesel vehicles are great for autobahn cruising if they are the mid-to-higher powered models because you get the speed combined with great efficiency. The A6 I used returned 41 MPG on average including many kilometers spend at 100 MPH.
For any autobahn and German road newbies who might read this a great site to visit to learn about the rules of the road and signage is: http://www.gettingaroundgermany.info/autobahn.shtml
Do you spend a lot of time driving on the autobahn network? Ever drive other Audi models on it?
Actually I was the passenger on this ride. Love that speed though. Germans are very good drivers.
