I'm not saying that you're wrong, but educate me. Please tell us your source or the formula that you used to come to this "fact".
Thank you.

Under the assumption that the fluid is not moving relative to the currently used reference system, the
power required to overcome the aerodynamic drag is given by:
Note that the power needed to push an object through a fluid increases as the cube of the velocity. A car cruising on a highway at 50 mph (80 km/h) may require only 10
horsepower (7.5 kW) to overcome aerodynamic drag, but that same car at 100 mph (160 km/h) requires 80 hp (60 kW).
[23] With a doubling of speed the drag (force) quadruples per the formula.
