If your eyes are quick you'll catch the comment about 'zero lift' associated with the airfoil. Free graduate degrees to anyone who comprehends it!

It's different in that, it fails to show the aft-body flow on the VW XL1.
When low drag really mattered, they put a low drag roof on the car, and it didn't need a spoiler, because the pressure recovery of the flow deceleration compensated for the high velocity/ low pressure generated near the windshield header.
