Slipstream
슬립스트림
It is the area of reduced aerodynamic drag formed behind a leading car. When a trailing car enters this zone, it experiences less air resistance, making acceleration easier and overtaking more advantageous.
🏆 Race Case Study
Using the Car Ahead to Prepare an Overtake
On a long straight, a following car can reduce aerodynamic drag by staying directly behind the car ahead. The driver can then pull out of the slipstream near the braking zone and use the extra speed to attempt an overtake.

Frequently asked questions
Why does a slipstream help a car go faster on a straight?
The following car can use the lower-drag region created behind the car ahead, reducing aerodynamic resistance and making it easier to reach a higher straight-line speed.
Are slipstream and dirty air the same phenomenon?
They both come from the airflow produced by the car ahead, but their effects differ. A slipstream can be beneficial on straights, while disturbed dirty air in corners can reduce downforce.
