No hills in south Louisiana but I must have had a nice wind to my back. All on a flat interstate. I drive like a grandpa ( because I am ) and I'm pleased with the gas mileage most of the time. Even city is never below 22.

Realistically, I could never reproduce 40.3 mpg again unless all the planets are aligned but I do make an 80 mile, all-interstate trip regularly and I very often get over 30 - 34 mpg in one direction. It has everything to do with the wind resistance. I still remember how hard it was to pedal a bike against the wind then coming home would almost require no effort.
