Mudança de regras de 2021 para reduzir rendimento

By Duncan Mil

March 21, 2021 - December 5, 2021 - Com as mudanças radicais nas regras da Fórmula 1 adiadas para 2022, asequipas usarão os seus carros atuais em 2021. Algumas alteraçõesaerodinâmicas e novos pneus da Pirelli serão os novos desafios.

The FIA has postponed the 18-inch wheels -- to deal with increasing downforce levels -- to 2022, but rule changes to try to curb the performance of the fastest F1 cars ever will apply next season.

Aerodynamic changes aimed to reduce downforce -- the interaction of the flat bottom of the car and the track surface -- threaten to slow down cars.

First, a diagonal exclusion zone around the rear tyres will reduce the area of the floor. From between 1,800mm from the centre of the front axle, the edge of the floor will no longer run parallel to the centreline of the car. The floor will be at its narrowest around the rear wheels.

A second rule change bans the longitudinal slots which create pressure vortices on the outer edge of the floor. Rear brake duct winglets are also reduced in size to cut downforce to rear wheels, and the diffuser between the rear wheels will lose 50mm to the height of its dividing strakes. All in all, these changes are designed to reduce downforce by 10 per cent.

Dual-Axis Steering, Mercedes-Benz’s innovative DAS which changes the alignment of front wheels, is also banned. DAS changes the alignment from “toe-out” on bends to increase straight-line speed.

2021 will also see a long-awaited cost cap, set at $145 million per team, with increases if the revised calendar of all 23 races all take place.
