Toto Wolff and Christian Horner’s row over flexing wings shows no sign of stopping after the Brit hit back at his Mercedes counterpart following Wolff’s post-race comments at the Monaco Grand Prix.  

The Austrian suggested his team could lodge a protest on Red Bull’s flexible rear wing if it proved to be a huge benefit on the long straight in Azerbaijan. However, Horner was having none of it and claimed that Mercedes’ front wing is flexing a lot.  

“If I was Toto with the front wing he’s got on his car, I’d keep my mouth shut,” said Horner to Sky Sports F1. 

“A lot of noise has been made about the rear wing, a lot of revisions had to be made.”

“If you’re picking on one end of the car, you have to look at the other. 

“You can’t look at one part in isolation and say ‘that set of rules only applies to that element on that car’, you have to look at all areas. 

“Sometimes, you have to be careful what you wish for.” 

Asked by the British broadcaster to describe his problems with Mercedes’ front wing, he said: “I’m not sure I have to say too much. 

“You can see the sponsorship [logo] on the front wing then it disappears as he comes into a braking area. 

“Maybe that’s what it’s for, it’s to expose the new sponsor on the front wing.” 

Along with Alpine’s Marcin Budkowski and Alfa Romeo’s Frederic Vasseur, Horner sees no reason why there will be a protest this weekend as all the teams with a flexi rear wing have passed the tests.  

Looking at Mercedes’ rear wing around Baku, he suggests they’re flexing more than Red Bull.  

“There’s obviously been a lot of noise that Mercedes have been driving about the rear wings, and the bottom line is that if the car complies with the rules, it passes the tests, it’s legal,” said Horner.  

“The FIA come up with the tests. That [the Mercedes] if anything, around here looks maybe a bit worse than ours. 

“I’d be more interested to see the front of the cars, than the rear of the cars. 

“You’re opening a complete can of worms. That’s why there are tests and there are stringent tests, that the cars are designed to comply with.”
