These are all multi-hundred mile drives setting the cruise control.
30 and 40 mph trips get 54 mpg or greater, per my Ultra-Gauge.
My wife's 2012 Elantra gets 29 mpg @ 80 mph, and 48 mpg @ 60 mph. Slowing down is the best thing you can do for fuel economy on long highway drives.

I get a pretty consistent mpg in the 40s between 50 and 70 mph. The xB has the same engine and similar drivetrain (the Yaris has taller gearing) and is designed off the same platform as the Yaris, but less aerodynamic body. I'll try and record the exact numbers at speed, but I remember not dropping below 40 mpg until about 80 mph.
