Getting Good MPG

I have a Hyundai Sonata which I drive with eco pro on and get ~30MPG 30/70% city/highway. It has a cd of about .29. On the highway, I get the table below:
50MPH 50MPG
60MPH 40MPG
75MPH 35MPG
This is with foot constantly on the pedal ensuring a consistent load on the engine which means slightly slower on uphills and slightly faster on downhills.

I've driven the X1 for 1000 miles and it's a totally different beast. With Eco Pro:
50MPH 50MPG
60MPH 40MPG
75MPH 30MPG
This falls inline with the large frontal surface area and the .35 drag coefficient.

Without eco pro, I get drastically worst numbers and if I inconsistently press the pedal, the MPG drops by 10-20MPG at the same speed. The only way to get the highest numbers is to drive anemically. I've done an 120 mile trip on less than 3 gallons in the X1 and I've also done a 50 mile trip on 3 gallons. MPG is 2/3 driving style and 1/3 the car you drive.
