sgtlethargic -- here's a "worked" example, that I did to check the aero-limited 124 MPH speed found by C&D and RT magazines for the Cruze LTZ, which (coincidentally!) also produced an estimated fuel economy of 32.7 MPG at 65 MPH, which is
exactly what my wife has gotten twice on the same stretch of Interstate heading from Phoenix into LA (actually 32.7 and 32.6, but close enuf).
