Mercedes is worried about the 2019 aero rules because even a backmarker team like Williams can rule the grid if they discover a good loophole in the regulation.
All the F1 teams are busy getting their aero right for the new regulations which are supposed to help improve the wheel to wheel racing. The new changes could contain some loopholes and if a rival team discovers it first and uses it, they may shake the entire grid order.
Team boss Toto Wolff is acutely aware that a repeat of 2009 is quite possible when Brawn GP came out of the back of the grid to win the world titles.
Speaking in Russia ahead of the FIA Prize Gala, he said: “I think with the rule changes everything is possible,”
“It is almost like 2009 where Brawn identified the double diffuser. I think there could be teams that have found loopholes, which others didn’t spot, that could make the difference.
“So, we are taking everybody serious: whether it is Ferrari finishing second this year or Williams finishing 10th. All of them could come with a car that can outperform us.
“We are respecting all these teams and the effort they put into it and all of them are being seen as competitors.”
Despite Mercedes winning the constructor’s title, the threat posed by Ferrari in 2018 means it will be even tougher in the next season.
“The points go back to zero at the start of every single year,” he said. “The challenge is going to be bigger than it was this year.
“We’re in a good mind, good spirits, that we can achieve it. But I can tell you: Ferrari and Red Bull and all the other guys will be trying everything to stop us.”
