Mercedes admits lack of budget to develop W17: “You can’t buy upgrades on credit”

Key takeaways

• Budget cap constraints: Mercedes Team Principal Toto Wolff admitted that the team is limited in introducing major upgrades for the W17 due to spending choices made early in the season.
• Front-loaded strategy: Mercedes prioritized initial performance to dominate the opening rounds, whereas rivals Ferrari and McLaren preserved budget to roll out continuous updates later in the campaign.
• Skeptical of rivals: Wolff questioned whether Ferrari and McLaren can sustain their aggressive pace of development through the final races without running out of allocated budget.

Before standing supreme in the first half of the 2026 Formula 1 season, Mercedes admitted it is struggling to invest in major upgrade packages for the W17 due to a limited budget, unlike what direct rivals Ferrari and McLaren displayed in recent rounds. Toto Wolff reiterated that this situation occurred because the German squad decided to concentrate its biggest development efforts at the very beginning of the year.

In effect since the 2021 F1 season, the cost cap was set at $215 million for this year due to the sweeping technical regulation changes—a figure significantly higher than the $135 million threshold from the previous season.

In Mercedes’ specific case, a large portion of the budget earmarked for car development was spent upfront to construct a project strong enough right from the start of the championship. It was no coincidence that the Silver Arrows comfortably won the first six Grands Prix, helping Andrea Kimi Antonelli—who took victory in five of them—leave the Monaco Grand Prix with a 66-point lead over Lewis Hamilton.

However, the picture began to shift from Barcelona onward. To put it into perspective, up until the Hungarian GP, the German team ranked second to last in permanent updates brought to the track with 20, while Ferrari and McLaren tallied 30 and 29, respectively.

Mercedes’ last major upgrade package debuted in Canada, seven races ago. Wolff explained in a press conference attended by GRANDE PRÊMIO in Zandvoort that Mercedes “does not have the resources to fund development on credit.”

“We tried to distribute this in a balanced way throughout the season, based on calculations about when we could bring the biggest upgrades and optimize championship points. But we can only do what is within our reach,” he emphasized.

“That is why there is a development race. When an upgrade is introduced, each of the top teams manages to gain a few tenths of a second, at least. And that is what you lose relative to them. So the journey has been a bit harder than at the start of the year,” Wolff added.

Next, Wolff questioned whether McLaren and Ferrari will be able to sustain their current development rate through the end of the year.

“We will see, near the end of the season, if they can implement as many new parts on the car as they are doing now. Some teams might adopt a different strategy, spending more at the beginning and middle of the year than in the final stretch,” he concluded.

Antonelli leads the Drivers’ Championship with 242 points, 59 ahead of George Russell and Lewis Hamilton, who are tied on 183. Lando Norris sits fourth with 159 points after winning the last two races of the year in Hungary and the Netherlands.
