Common Misconceptions in Aerodynamics: Part 6
Last time, I wrote about the myth of waxing your car for lower drag. Next, we'll look at a misconception that's a little more nuanced.
The Front of the Car is Just as Important as the Back for Reducing Drag
|Spoiler alert: "Hucho's book" says nothing of the sort.|
The reality: The half-truth that “the back of the car is aerodynamically more important than the front” is repeated over and over online. Simple statements like this are more often wrong than right, and you can probably guess why this one is more nuanced in reality than many claim.
Yet online commenters don’t seem to understand this. I posted the results of my pressure measurements on a well-known web forum and was immediately met with skepticism, argument, and outright disbelief. One person accused me of misunderstanding pressures and aerodynamic forces in general (incidentally, this person is a vehement “template” promoter). I believe this is the natural result of the community never bothering to test things for themselves, and their lack of familiarity with any current resources or textbooks on car aerodynamics. In effect, they shout into a self-supporting echo chamber. Don’t be like them. Read, verify, design, and test (seriously--don't believe me! Go measure pressures on your own car).
