What is the purpose of the 'plastic baffle' under the front bumper of my Xiaomi SU7 Ultra?
Official answer
This 'plastic baffle' is the front splitter of the Xiaomi SU7 Ultra, an important aerodynamic component. The front splitter significantly reduces the amount of air entering the underside of the vehicle, effectively preventing lift caused by airflow accumulation, thereby noticeably increasing the downforce on the front axle.
The Xiaomi SU7 Ultra offers an optional carbon fiber rear wing. When this wing is selected, the front splitter is equipped simultaneously to ensure a balance of downforce between the front and rear axles, allowing the Xiaomi SU7 Ultra to achieve a maximum downforce of 285kg, effectively enhancing handling stability on the track.
