At 160-180 km/h in a rental 116d with winter tires I was actually getting about 6L/100km. I was able to do Berlin to Auschwitz (Poland) on a single tank, with 0.2 tank left over. (Poland technically has speed limits I think, but they weren't enforced) For a combination of high-speed-autobahn and city/etc driving, I was basically refilling for EUR 65 or so every 600-700km. The rental 116d couldn't do >200 km/h, so I'd probably want something a bit bigger, but even a 123d would be a reasonable option. I was thinking 535d just in case I had to have passengers.
