Ferrari revolutionises SF-25 floor: all the changes explained. Ferrari brings a new floor update to Austria.

Ferrari brings a new floor update to Austria: all the aerodynamic modifications to address the 2025 issues.

Ferrari introduced a major update to the floor in Austria during the Grand Prix weekend, aiming to solve the main limitation of 2025: the difficulty in generating aerodynamic downforce at low speeds. The problem lies in the need to keep the car too high off the ground to prevent the plank from hitting the asphalt, thus compromising cornering performance.

Looking at Monaco, this handicap was less evident, since all teams must raise their cars to deal with the bumps on the track. But on circuits like the Red Bull Ring, where rivals can run lower, Ferrari loses grip compared to Red Bull, McLaren, and Mercedes. This is why significant changes to the floor were necessary.

According to The Race, Ferrari removed an external front support and introduced a terminal attachment that improves airflow through the lateral slot. This allows the small wing on the floor’s edge to work better when the car is higher off the ground, increasing downforce efficiency even at low speed.

The transition between the front and rear sections of the floor has also been modified. The new profile allows better airflow management in that area, which is crucial for the car’s stability. Moreover, Ferrari updated the flow distribution and the shape of the internal splitters, which are key to boosting the diffuser’s performance.

Minimal but targeted changes were also made to the upper fin on the floor, which can generate a more stable vortex. This improves the scavenging effect in the front area and, consequently, the diffuser’s performance at the rear. The design of the rear slot was also revised, changing from straight to curved, to ensure stability and avoid porpoising.

Finally, Ferrari brought a new diffuser. The changes do not affect the outlet but rather the way air expands from the floor into the diffuser itself. According to Maranello’s engineers, the key will be resisting the temptation to lower the car too much: “If we don’t overdo the ride height,” said one technician, “we might finally have made real progress.”
