In the hybrid Avalon I've noticed a huge drop in fuel mileage above 65mph (obviously air drag) (about 35mpg).

At 55mph to 65mph I don't notice much help from hypermiling. (about 40mpg)

Below 45-50mph I start getting worse fuel mileage unless I hypermile (drive with the power meter right at the line between ECO and PWR then let off the throttle and coast with engine off), Then I get better fuel mileage than around 55mph (or about 45 to 50mpg).

Ideally we'd have much smaller engines that output an average amount of power, locked at the most efficient RPM and Load, and the fluctuations of needed power would be administered from a highly efficient hybrid system.
