Floor

The design of the floor has been revised to improve airflow underneath the car. The new sidepod and bodywork design complement this, allowing better airflow management under the car and over the rear wing.

Much of the car's downforce is generated by the floor. Extracting the most from this area is key to unlocking performance; the floors of F1 cars have been a key development battleground since the current technical regulations were introduced in 2022.

The floor of an F1 car features a complex series of channels and tunnels that work together to create downforce and reduce drag. The channels guide air through a narrowing section under the car which then widens towards the rear. This narrowing and widening accelerates the airflow, creating a low-pressure area that generates additional downforce and pulls the car closer to the racetrack – also known as ground effect.

At speeds of around 150km/h, the car can generate its own weight in downforce.
