DRAG goes up as Square of velocity. HORSEPOWER goes up as CUBE.
Really?
Maybe someone can explain how this works...
If most of the drag on a car at speed (like >100 MPH) is aero, and aero drag goes up as a second power function of the increased velocity, how come HP needed would go up as a third power function?
In other words, if air resistance is the
largest single factor in drag, and if it goes up 4X when I double the speed... where's the other "horsepower vampire" hiding here?
Just tryin' to understand...
