In short, if you're looking for a vehicle that gets better gas mileage at 70 than at 60, you are not likely to find it.
I don't think that was the question (though my Insight does get better mpg at 50 than at 35). Rather, if you are constrained to travel at a certain high speed, what vehicle(s) will get the best mpg?

I think that's going to come down basically to CdA plus tires: a small car with good aero, and LRR tires.
