In seriousness though, if we add the performance of a Stohr DSR car (~200bhp, 450kg incl driver) to my VIR chart, you can see that it is only slightly slower than the Deltawing but uses only 57% of the Deltawing's power (and hence, roughly, 57% of the fuel consumption). In terms of fuel used to lap time it massively out-performs the Deltawing. Giving it an ACO crash-tested tub would add some weight, but then giving it the same power as the Deltawing would make it VERY VERY quick indeed....

And hence my whole point about the fallacy of the DW concept...it only proves ONE thing: open aero regulations allow for efficient designs. Other than that, the (effectively) three wheel concept is tying one hand behind your back for no reason.
Give the Stohr the development budget of the DW and you'll be miles ahead.
BTW, the Tucker DSR was predicted (lap sim) to lap Road Atlanta in 1:14-1:15 range, though the engineer conceded it might even go better...
