Slipstream — also known as drafting — is the effect where a car following closely behind another benefits from reduced air resistance. The leading car punches a hole through the air and creates a low-drag pocket directly behind it. A car driving in this pocket needs less engine power to maintain speed and can travel faster on straights. In Formula 1, drivers sometimes deliberately sit in the slipstream of a rival to gain speed before an overtake, particularly in qualifying at high-speed circuits like Monza.
Example: He’s tucked into the slipstream on the main straight and he’s gaining a huge amount of speed on the car ahead.
Slipstream helps on straights by reducing drag; dirty air hurts in corners by disrupting downforce. They are related but opposite in effect — one is an advantage, the other a disadvantage.
