Based on quoted top speed compared to the standard vehicle, I work it out at Cd=0.33.

Addition: When Aerohead was sending me details on his vehicle for inclusion in my book it soon became obvious that a lot of what he was saying was of somewhat doubtful validity - like an absurdly low Cd measured in a tiny wind tunnel. I then asked for the top speeds in standard and aero-modified forms, did the calculations and got a Cd of 0.37. Dr Wolf then corrected my maths and got a Cd of 0.33, the one I have quoted above. I chose not to run any claimed Cd figure next to the truck.
