Signed up to post about this one. Several sites misquoted the 0.11 as Cd, when it is definitely CdA in meters squared. In sqft, that's 1.27. I'd expect the Cd is still very low.
For comparison, our electric (Team Speed Hertz) that ran BMST this year has 5.625 sqft of frontal area and an estimated Cd (CFD, still analyzing run data, but it's in the ballpark) of around 0.29 for a 1.63 CdA. In those other units, that's 0.152 meters squared. That's 25ish% better...seems pretty reasonable to me.
