Over 3,000 km, mine is currently averaging 8.55L/100km. And it is improving over time, using same traffic/roads. It's dropped from 12.6 (over first 250km) to 9.06 (over 602km) to 8.23 (over 504km) to 8.00 (over 610 km) to 7.44 (597 km) to 7.1 (the last being a drive with mostly freeway). Based on this, I expect to see low 7's, maybe high 6's
By comparison, my F20 M135i is averaging 8.05 L/100km over 53,000 km, so it is possible to run close to the stated fuel economy with some care. I always use 98RON fuel, which is the highest octane premium fuel readily available at petrol stations in Australia.
(Yes, for tax reasons, I log all fuel and distance on both our cars....anal retentive
