I average ~4 mpg higher in my 2012 than in my 2001 (Zetec) Focus in virtually all driving scenarios. That agrees with the difference in EPA ratings between the cars, and is pretty good when you consider that the 2012 is 300 lbs heavier and has 30 more HP on tap.
Overall average: 31.5 MPG (2001 was 27.9)
MPG @ 70 MPH, flat cruise: 36 (2001 was 32)
