F1 chief Ross Brawn sets alarm bells ringing for Mercedes and Lewis Hamilton

Mercedes and Red Bull have been warned by Ross Brawn that they "could be impacted" the most from new regulations brought in for the 2022 F1 season. The hybrid era of F1 saw Mercedes dominate over the past few years with Lewis Hamilton adding six World Championships to his single triumph with McLaren earlier in his career.

Brawn knows better than most on how to capitalise on regulation changes having helped Jenson Button to his maiden F1 World Championship 13 years ago.

Drivers have also begun their shakedown tests this week with some explaining issues with visibility due to the much bigger 18-inch tyres.

"Mercedes and Red Bull could be impacted," said Brawn.
