Red Bull brings floor modification to Red Bull Ring aiming to catch McLaren | F1 Austrian GP. Red Bull introduces a new floor upgrade on the RB21 at the Red Bull Ring.

Red Bull does not want to disappoint its home crowd, arriving with a new floor upgrade on the track that bears its name. These are localized but significant modifications for the RB21, with the ever-present uncertainty about the correlation between real track performance and wind tunnel data. The Milton Keynes team is determined not to surrender to McLaren’s superiority, following a different development approach compared to their Woking rivals.

The floor at the Red Bull Ring
Austria marks the fourth floor upgrade of the season for Red Bull. The first update debuted around the preseason testing and the opening race in Melbourne but was then set aside after Bahrain. The team introduced the third version in Miami, celebrating a victory two weeks later at Imola. Now the hope is that the floor brought to Styria will have the same positive effect.

As always with ground effect Formula 1 cars, the most important changes are hidden underneath. However, from the outside, one can notice a significant modification at the end of the knife-edge profile along the sidepods, just in front of the rear wheels. Red Bull opens a vent between the upper and lower parts of the floor, inspired by designs seen on some rival cars but differing from McLaren’s solution.

Although not a revolution, it is still an important change, given the final months of the current technical regulations. It will be interesting to evaluate Red Bull’s approach: whether to maximize already strong performance in high-speed corners or try to close the gap in slower sections. First, however, the team must verify the correlation between track data and wind tunnel, a weak point in updates over the last two years.

Different approaches
Overall, it’s interesting to note how Red Bull and McLaren are working on development in fundamentally different ways. The papaya team focuses more on suspension, working mechanically to improve drivability and better stabilize floor attitudes. Red Bull, meanwhile, continues to modify aerodynamic surfaces, delivering four floor updates since the start of the year compared to McLaren’s single one. The world champions still hold a significant technical advantage, but Milton Keynes has no intention of giving up.
