Toto Wolff has pushed back against Fred Vasseur’s angry response to his recent comments about Ferrari’s upgrade programme during the 2026 Formula 1 season.
The dispute has been building throughout the British Grand Prix weekend, with tensions first surfacing at the previous round in Austria.
Wolff had expressed surprise in Austria at the rate Ferrari has been producing upgrades, pointing to the Scuderia’s second major update package of the year, introduced in Barcelona in June.
That Barcelona upgrade proved significant, with Lewis Hamilton ending Mercedes’ unbeaten run at the Catalunya circuit on behalf of Ferrari.
“We’re a little bit surprised that Ferrari can throw these huge updates at the car in the way they do,” Wolff said at the Red Bull Ring.
“In my opinion, they need to be running out of cost cap money soon, because we can’t do that.”
Vasseur responded sharply on Friday at Silverstone, suggesting Wolff’s comments amounted to an accusation of cheating against his team.
“When Red Bull is developing or when Mercedes is developing, they are genius,” Vasseur told the media. “When we are developing, we are cheating. I think you have to calm down with this.”
Wolff was then asked about those remarks after qualifying, in which Mercedes’ Kimi Antonelli claimed pole position ahead of Ferrari’s Charles Leclerc and Lewis Hamilton in second and third.
“Fred is very emotional,” Wolff told Sky Sports. “If you would have read my comments, rather than just a headline, he would have seen that what I said was an observation and would be interesting to see how much updates one can pull out at the end of the season.”
Wolff acknowledged that his original words had been taken in a direction he did not intend, insisting no accusation of financial wrongdoing was ever made.
“I know it was misunderstood,” Wolff said. “If I say things that I want to be understood, I will do so too, but in that case, I didn’t mean it really.”
Vasseur had also noted that Ferrari’s update volume was no greater than that of Red Bull or other rivals, dismissing the premise of Wolff’s original observation entirely.
“We didn’t bring more parts than Red Bull or another [team],” Vasseur said, adding that implying a cost cap overshoot was effectively moving into accusations of cheating.
Despite the sharp exchange, both principals are known to share a long-standing personal friendship, which Vasseur indicated would not be permanently damaged by this episode.
Vasseur told Sky Sports Germany “we will have time to speak during the break,” pointing to the summer break that follows rounds at Silverstone, Spa, and Budapest.
The row underlines just how fiercely competitive the battle between Ferrari and Mercedes has become in 2026, with both teams trading both upgrades and words as the season intensifies.
