But honestly, it's just such a basic mistake to keep on making.
Take it up with Hucho. It's his quote. It's the entire premise for road vehicle aerodynamic study.
Total drag can be reduced to surface friction drag in the absence of separation.
80% - 90% of total kinetic energy can make it to the rear stagnation point on a streamlined car.
I'm familiar with diagrams. I'm familiar with context also.
