Formula 1 and the rennovation in the 2021 season (Part 3)

10 years ago, F1 had six engine suppliers: Mercedes, Ferrari, BMW, Renault, Toyota and BMW. This season, only the Mercedes, Ferrari, Honda and Renault are available. Autosport revealed Porsche and Aston Martin will join F1 from 2021 if new laws are passed.

Another plan to attract motor manufacturers back to F1, is to improve the energy department (PU). F1’s new energy department must be cheaper, simpler, healthier and make a bigger noise. F1 aims to use electric turbochargers (hybrid turbocharger) in the future. Important details will be simplified to make it easier for the audience to understand. Some parts such as batteries will be standardized, to reduce costs. F1 may also no longer limit the amount of gasoline a vehicle can carry.

“We are living in the era of machine technology. But, they are too expensive and unsuitable for racing. I want to see a more balanced race between drivers, helping bring more emotions,” Brawn said.

Energy department improvements are supported by all four motor providers. “We want to let drivers adjust some machine parts, such as the energy recovery system (ERS) from the engine or from the battery. At that time, they have the opportunity to overtake the opponent, thanks to the right strategy, Engineers agree with this change,” Brawn added.

One of the controversial adjustments about ERS is the abolition of the energy recovery unit (MGU-H). MGU-H has the effect of turning the heat generated from internal combustion in ICE (internal combustion engine), turning the turbine and regenerating electrical energy. According to BBC, Porsche only participates in F1 engine production if MGU-H is omitted. Initially, Ferrari, Mercedes and Red Bull objected to this. But, this is a cost-effective option for racing teams and reducing vehicle weight.

The most complicated aspect is a change in technical regulations. Cars need to be easier to control and improve their chances of surpassing. “Currently, vehicles that use the ‘wind-blow’ strategy behind other vehicles often lose 50% of the force. This number is too large. We are working to make cars that hide the wind take only 5% to 10% of the force, helping drivers have a chance to overcome, “Brawn told Sky Sports.
