Just got my first fill-up, here's another data point:
90% city / 10% highway
36.06 MPG hand calculated
The car was reading 32.5 MPG average, so it was a huge surprise to get 36! This includes around 20 miles driving on the spare due to a flat, and another 20 miles of spirited mountain roads. I'm very happy, this is more than double the efficiency of my last car.
