I have a new SMART Passion and driven about 1300 miles city driving in Los Angeles. I am averaging between 22 to 25 miles per gallon. And that is consistent. Now my SMART rep tells me that the mileage will get better, but I am really concerned since this so much lower than the mileage quoted by SMART. This equals appr. 9 plus ltr per 100 km. Anybody with similar experience?
