All the testing at Edwards was coastdowns on the South Base runway using stopwatches and accelerometers.A 312-mile driving loop through the Mojave Desert was used for mpg testing.No mirrors,no cooling system drag for coastdowns.
Rolling force coefficients were obtained before any aero work was initiated.
Tabulated results were compared to those of Sighard F.Hoerner with very close agreement.
In later follow-on research,the University of Kansas at Lawrence,KS, scale wind tunnel was used.
Later,the Dryden Flight Research Center did get a small wind tunnel,but it wasn't used for the automotive testing.
