A term used to describe the wake of dirty air that flows off the back of the car creating a zone that reduces the aerodynamic performance of the following cars. This limits the amount of time that cars can compete wheel-to-wheel as the challenging car will start to experience performance issues such as overheating or tyre degradation.

F1 cars operate on the edge so there is zero tollerance to reduced aerodynamic performance.

In 2022 new regulations were introduced to better manage the dirty air with the intention of improving the spectator experience, allowing closer racing and providing more overtaking.
