Cool! I could drive like a complete madman and still get 22.5 as my daily trip is 2/3 highway. The only time the car ever gets down in that range is in the winter when it is being warmed up before driving. During normal driving the gauge is normally at around 28mpg which is around 25.2mpg at the pump. That is with fast acceleration, driving 65mph with cruise, full climate control, taking extra trips in town (more city milage), and coasting (motor on) only when the hill is steep enough that speed is maintained. It would take effort to get the mileage down to 22.5 in the summer. Breaking 30 is another matter, that is a bit tricky.
