Over the season, Red Bull introduced small modifications to the leading edge of its underfloor. At the beginning of the year, it had a package of three vertical turning vanes and one larger one on the forward-facing fingers of this area of the floor. In France, it was reworked and had five plus one, which are further rearwards. Any improvement helps the performance of the front wing, and helps the airflow along the outer sides of the underfloor act like a skirt. This reduces the amount of airflow that leaks into the low-pressure area underneath the car, improving the performance of the underfloor.
