• 10.1HP = 26.20*(lbf) + 0.1554*(lbf/mph) + 0.01686*(lbf/mph^2) ...so, lbf = 0.385 @ 50 MPH (A6)

Anybody with an Eco Cruze know if these match-up with the applet we have here?
Edit: Nope, the EPA is modeling road load as F=A+Bx+Cx², and we are modeling it as F=A+Cx². Our applet crunches drag area, air density, vehicle mass, etc into two road load coefficients, whereas the EPA has a more sophisticated model.
