It actually is possible to get more MPGs at a higher speed than a lower speed, because a specific engine may have a certain RPM range that's more efficient for the load. It takes more energy to get up to speed, but once you hold a steady cruise, the results can be surprising.

Driving back from my dealership, bring home our new Mirage, I got 49.9 MPG doing 60mph, freeway was basically flat. Got on the next freeway to get home, I decided to drive 70mph. MPG was at 36.5, huge difference in my mind! Of course I understand the road was slightly uphill most of the time and a couple large hills, but I was still expecting 40MPH or higher.

Are not the 44MPG HWY federal specs considered at 70MPH? Surely they don't get those figures from driving 55, or do they?

My last trip I was doing mostly 70mph and I was Getting Between 48 to 50.2 MPGs and that's with a CVT

I never drive that fast! I never go faster than 60-62mph, regardless if the speed limit is higher. Just not in that big of hurry to go anywhere.

I regularly pull 42+ mpg's and I cane this poor car like its a weekend rental. I love to hear the motor sing at higher rpm's, and it shifts very solidly for an eco-box. Occasionally I drive sensibly, and easily see 50+ mpg's.
