Why is 300 mph so hard?

All of this has to be taken into consideration when choosing an engine for speed records. But in the end, the biggest obstacle to 300 miles per hour is air. The drag, or air resistance, that a car encounters as it approaches this speed, can be compared to what you encounter when swimming.
