I did 157mph in an Audi A3 in Germany. We got passed by a big Mercedes sedan that must have been doing 200.

I only ever did 150 on the autobahn. We were getting passed by diesel Peugeot wagons driven by soccer moms.

I had a 2009 Mercedes 220cdi (diesel) - little station wagon, drove it 150 mph on the autobahn (clear, cool day, very long sight lines). Wife didn’t appreciate the speed, though the kids loved it. Normally kept it under 130 mph, what was amazing was that it was still getting 35 miles per gallon at those speeds. Didn’t accelerate quickly, but that was fine.
