T-wing

A T-wing is a small, T-shaped aerodynamic device used in Formula 1 racing to improve a car's performance by generating downforce and influencing airflow.

Most prominently seen during the 2017 F1 season, T-wings were mounted on top of the engine cover behind the driver. Despite their small size, these wing-like appendages helped cars stick to the track better in corners by pushing them downward and could also direct airflow more efficiently toward the rear wing.

T-wings became controversial due to their tendency to vibrate and occasionally break off during races, creating potential hazards. This led Formula 1's governing body to ban them from the 2018 season onward, though they remain an interesting example of the constant aerodynamic innovation in motorsport.
