I'm on there too Zeeper, and if you look at the average for 2012, It's 27.7, 26.7 for 2013.
Calculated, the city MPG is 27, Highway is 36, making the combined being 31.5MPG.
So that means the 2012 is on average 12% off the mark, 15% for 2013.
Hyundai and Honda got punished for a fleet average LESS THAN 10%
If you search through Fuelly there are 16 people who have met the 31.5 MPG mark, out of 211 cars.
So 7.6% of people make the mark. That does not seem like many people to me.
