Ferrari has spent 2026 bolting new parts onto its car at a rate no rival can match, and it has finally rattled the paddock. Mercedes boss Toto Wolff used the run-up to the Belgian Grand Prix to question how the Scuderia keeps finding performance without blowing through Formula 1's cost cap — and Ferrari's camp pushed straight back.
Wolff's argument is about arithmetic. Ferrari has declared 32 individual upgrades this season, including major packages in Miami and Spain, where it won in Barcelona. Mercedes has brought 17, built around one big step in Canada.
"We're a little bit surprised that Ferrari can throw these huge updates at the car in the way they do," Wolff said. "In my opinion, they need to be running out of money soon — cost cap money — because we can't do that."
He went further on where Mercedes sees the limit. "We're simply lacking the buffer and the cost cap to be able to bring so many parts in the way they do," Wolff said. "The only ones who are not slowing down is Ferrari. It's just Ferrari, who seems to be limitless in that way."
Charles Leclerc wasn't biting. Asked at Spa whether the spending questions worried him, the Monegasque put his faith in his team principal. "On that, I trust Fred more than anything," Leclerc said. "I'm sure Fred is on top of that, so am I worried? I am not, because I fully trust Fred and I know that he knows what he's doing."
Vasseur framed the upgrade blitz as timing rather than extravagance — spend early, bank the lap time for longer. "If we can bring something at the beginning we do it, and it's better to have a couple of tenths for five races than just a couple of tenths for the last two," the Ferrari boss said. He has also played down the scale of what Ferrari brings: "Sometimes you can have the feeling that we are bringing a big upgrade but this is just a modification of some parts."
The more revealing answer to Wolff's question came from the teams who can't do what Ferrari does. Williams principal James Vowles said the gap isn't only money — it's infrastructure built over years. "They have a far more efficient set of processes behind them," Vowles said. "Take Williams, we didn't have an external supply network at the right level because there's no funds to pay them." He pointed to Mercedes having spent 12 years building supplier relationships, then summed up the trade-off: "That means there's a loss of efficiency and it can be time or cost. You can choose whichever one of those two levers you want to pull, or both."
Aston Martin's Mike Krack made the same point from the planning side. "If you bring an upgrade every week, you have to plan this long in advance," he said. "You cannot say, I was poor in Austria and I have an upgrade in Silverstone the week after."
That is the crux of it. Wolff suspects the cost cap will catch Ferrari before the year is out; Ferrari insists it has the numbers under control and is simply better organised. Both teams will almost certainly finish the season inside the cap. What Wolff's needling really underlines is that Ferrari, for now, has turned development speed into its sharpest weapon — and the midfield can only watch.
