When the drag force was associated with the actual frontal area,the drag came out at:
* Cd 0.1209 for the long tail
* Cd 0.1487 for the truncated tail
* Delta 0.0278
* Delta 22.9%
--------------------------------------------------------------------------
Rolf Buchheim's 1981 VW 'Flow' body registered
* Cd 0.14 for the long tail
* Cd 0.15 for the truncated tail.

Baby has wider tires than the 'Flow' (215mm vs 155mm),but full wheel fairings,which helps explain the lower long tail Cd in spite of the mutilation which accommodates taillights and license plate.
The truncated values are quite similar.
Cambridge University's CUER scores Cd 0.11 with skinny solar race tires.
When we can get the video of the smoke flow up,you'll want to bear in mind,that you'll be looking at is 30-mph,sub-critical Reynolds number, high-drag laminar boundary conditions.
Only with the full 570-hp fans screaming at maximum thrust does Baby see critical Reynolds number,full,turbulent boundary layer,low-drag flow.
Too bad we can't do smoke imaging for that.
