Decrease those pressures on the front, and/or increase those pressures on the back, and you have less drag.

We don't have to compare the pressures to other shapes; we simply work on changing the pressures on the car we have.

Maybe he needs to watch the video?

Maybe I need to ignore comparative analysis of your measured pressure profiles.
1) according to your own measurements, and all normalized to 70-mph ( 112.654-km/h ):
* the Jaguar XE has the lowest drag ( delta 379.6-pounds )
* the M-B 230 has the next-lowest drag ( delta 392-pounds )
* the M-B 211 has the third-lowest drag ( delta 397.4-pounds )
* and the 1st-gen Insight has the highest drag ( delta 660.2-pounds )
* In light of the fact that M-B 230 has the highest published drag, while the Insight has the lowest!
I find this very interesting and worthy of explanation.
