A report from RacingNews365.com states that the car’s floor sills have been agreed to be raised by 15mm. The excessive rebound of the new Formula 1 cars this year has proven to be a problem for a number of drivers, especially Mercedes drivers.
Lewis Hamilton and George Russell were affected by their car’s heavy rebound, which contributed to a poor start to the season, especially the seven-time world champion. Silver Arrows decided enough was enough and demanded changes and now it appears their wish has come true.
Mercedes team principal Toto Wolff has been a staunch supporter of raising car floors, citing concerns about the effects of rebound on drivers’ health. “The FIA has commissioned medical work on porpoise hunting,” said Wolff.

“The doctors summary is that a frequency of 1-2 Hz, continuous over a few minutes, can lead to brain damage. We have 6-7 Hz over several hours. So the answer is very easy: the FIA needs to do something about that . ”
There were worrying signs for Mercedes at first, as the FIA decided they might take a vote on proposed changes to the porpoise rules. To combat this problem, the FIA originally suggested that teams should raise the floor sills of their cars by at least 25 mm for next season.
Manufacturers will also have to raise the underfloor diffuser and will undergo stricter testing for lateral floor deflection. The planned regulations changes have split the circuit with Ferrari and Red Bull accusing Mercedes of pursuing the modifications only because they have not been able to solve their own porpoise-hunting problems.

The FIA planned to hold a vote on the issue at the World Motor Sport Council, which means the planned changes may not happen at all. Regardless of the vote, the FIA can still act at its own discretion and move forward with the proposed rule changes, which it has now done.
After a careless start to the 2022 campaign, Mercedes has bounced back over the past several races. The last two races have seen both Hamilton and Russell on the podium and the British duo will look to continue their momentum when Formula 1 resumes after the summer break in Belgium.
