not every car gets better mileage at lower speeds, as already stated. all depends on the motor and gearing. bigger motors like to breathe more, and can get better mileage at 75 then 55. someone on tech posted his friend has i think a big jaguar. he gets near 30 at 75-80, but very low 20s at 55, which is where the EPA rating was.
