The phenomenon of boiling, twisting vortices being generated by winged F1 machines has been an issue through the generations.
But in the championship’s moves to improve its entertainment spectacle, particularly over the last 20 years or so, the desire to clean-up outwash airflow generated by cars to allow following drivers to stay close behind a rival and not slide in the unstable air buffeting their own machines has regularly been cited.
The move to ground-effect rules for the current era, with airflow sent higher and wider by such designs plus the desired slashed reduction of the outwash effect through simplified front wings, had a clear target of eliminating as much dirty air as possible as the cars traversed corners to improve racing.
