Formula 1 reveals 2021 auto and regulations

Share

At long last Formula 1 has finally released its regulations for the 2021 season and beyond, with the punters and better racing at the heart of the overhaul.

After two years of discussions and negotiations between officials and teams, F1 and the FIA revealed the regulations after receiving the "unanimous, quot; approval of the World Motor Sports Council on Thursday".

Formula One has released details of its new set of regulations from 2021 onwards as the series' management seeks to bring about more exciting racing, greater competitive balance and improved financial sustainability in the sport.

The simplified aerodynamics are meant to clean up the airflow around the cars on track, mitigating the effects of "dirty" air on the competitive environment, and theoretically making overtaking maneuvers easier. From the outset it would seem that F1 is trying to address all three in one fell swoop.

Should the number of races increase, teams will be permitted to spend an extra US$1million for every additional race, with the figure reduced in the same way if the calendar is shorter than 21 races.

"But even the vehicle that has been developed in CFD and developed in the wind tunnel has already got a respectable amount of performance". However, it excludes the marketing costs, driver salaries, and the salaries of the team's top three personnel. Independent regulators will be appointed to make sure teams aren't spending dollars they aren't allowed.

"This has teeth. If you fraudulently breach the financial regulations, you will be losing your championship", he said. It's anticipated that the competitive advantage some teams now enjoy will be reduced. That should please lots of people - ditto the new shape of cars that the regs are predicted to create. Sweeping body work with 18-inch wheels and lower profile tyres are the most visual design cues that will change. The air will also be directed higher, meaning less impact on the vehicle behind and closer racing.

Extensive research has gone into making the 2021 auto concept easier to race than the present generation of F1 cars, reducing the overall loss of performance in dirty air.

This will be achieved by finding a way to decrease the loss in downforce that chasing cars experience while stuck in the "dirty air" behind another auto. Yet, for 2021 this is hoped to lower to around 5-10 percent as the airflow will be directed higher once it leaves the auto.

Technical changes to the heavier vehicle include tweaks to aerodynamics and a bigger wheel size, and a speed reduction of up to 3 seconds per lap is expected.

The restrictions on how many parts teams can supply other teams are only concerned with what is supplied, in other words only those components that fall into the category of Transferrable Components or Prescribed Design Components.

"Whereas before we had the resource restriction, which was a gentlemen's agreement between teams - well there's not many gentlemen in the paddock I'm afraid, and that was a failure".

The sport will stick with the existing V6 turbo hybrid engines introduced in 2014 after abandoning plans to change them.

That's a wrap for the key rule changes. However, with the 2021 auto design, this drops to around 5-10%, with airflow coming off the new cars both cleaner and directed higher, meaning it has significantly less impact on drivers following, giving them the chance not just to overtake, but to battle.
