Mercedes and 
McLaren have also brought updates. Mercedes has added a new vane to the wing end plate of the rear wing, meant to improve airflow at the bottom of the wing. McLaren, in turn, has introduced a new beam wing sidepod inlet.
Aston Martin has a new front brake duct, with a smaller intake compared to the previous version. AlphaTauri carries a new rear wing and rear-view mirror and 
Williams has brought a small update to the floor. Red Bull, Alpine, Alfa Romeo and Haas do not carry any new parts.
