I know none of us bought the ST for the gas milage, but the car is certainly capable of great milage. I took mine on a 500 mile trip for business and I go 37.7 MPG for the first 381 miles of the trip. That's not the dash display but doing the math. I have 40.2 displayed for the last 120 miles of the trip and the car really loves cruising. This was doing 60-65 MPH with some slower traffic due to the snow yesterday in the Northeast. Also, I spent 10.5 hours in the recaro seats and was totally comfortable the whole way! So glad I upgraded to this car!
