FIA Announces Changes To F1 Aerodynamics And Tires In 2021

The Federation Internationale De L’automobile (FIA) and Formula 1 have revealed changes to the pinnacle of motorsports that will be implemented in 2021.

The aerodynamic regulations for 2021 will be designed to address difficulties following and “attacking” rival cars. Currently, the airflow channel has an effect of reducing downforce on the following car, making it hard to stay close and making the car move around more, leading to overheated tires.

In place of the complex front wings and bargeboards, Formula One will also pursue a ‘ground effect’ solution that will see downforce generated underneath the car.

“There’s a diffuser going right under the car, with a Venturi-type channel running through it. The tunnels go right from the front to the back,” FIA Head of Single-Seater Technical Matters, Nikolas Tombazis, explains. “[With the 2021 car] typically, we will go from about a 50% loss of downforce for the following car at two car distances [in 2017] to about a 5-10% loss. So we have a massive reduction of the loss of downforce for the following car.”

One element still under discussion, however, is the final specification of the front wing.

Regarding tires, the biggest alteration is the move from 13-inch to 18-inch rubber.
 
“We are into a deep consultation with Pirelli about how to be in a position where [the tires] enable people to race and don’t degrade or force people to manage so much,” explains Tombazis. “They will need a broader working range and will not be as sensitive as the current tires. We have understood jointly quite a lot of things that will make a significant difference in that respect.”

Additionally, officials have outlawed the use of tire blankets in 2021 and beyond.
