Andrea Stella, the team principal of McLaren Formula 1, is doubtful of Toto Wolff’s assertions that Mercedes lacks the financial headroom to accelerate their development upgrades.
Recently, both Ferrari and particularly McLaren have secured substantial progress with their 2026 challengers, capturing two victories each and placing heavy strain on the previously dominant Mercedes squad.
In contrast to their competitors, Mercedes has introduced only a handful of aerodynamic developments, with plans to debut a more substantial package during October’s Bahrain Grand Prix located in Malaysia.
This hesitation leaves Mercedes vulnerable to additional setbacks during the upcoming trio of September races across Italy, Spain, and Azerbaijan. However, when Autosport questioned Wolff after the Dutch Grand Prix about whether these development choices were growing difficult given McLaren’s swift advancement, the Austrian explained that Brackley is constrained by how they allocated their $215 million budget cap limit.
“The funds to continuously add upgrades to the challenger are simply not there. As previously mentioned, we aim to distribute our resources uniformly across the campaign, calculating how to deliver our most significant packages while maximizing our points tally. Ultimately, we cannot exceed our limits,” stated the Austrian.
“It will become clear late in the campaign if our rivals can maintain their current rate of development. Other teams may have chosen an alternative approach, front-loading their expenditure in the opening and middle phases of the year rather than holding back for the finale.”
Presented with these remarks, McLaren boss Stella responded: “While I would love to take your word for it, I simply do not buy it.”

Stella’s dubiety stems from the impending 2027 engine rules—shifting Formula 1 to a 57-43 ratio between internal combustion and electrical power while reshaping specific chassis elements—which feature a $3 million budget cap exemption applicable in 2026 or 2027 to ease the transitional preparations for teams.
If Mercedes genuinely desired to, Stella argued, they could utilize that specific allowance to manufacture updated components for their car.
“Every competitor has a specific allowance within their budget cap declarations,” Stella remarked. “If my memory serves me correctly, there is roughly a three-million-dollar buffer that can be integrated into the 2026 budget cap figures. Given that Mercedes has observed their competitors raising the bar, I am convinced they will utilize the progress they are undoubtedly making behind the scenes.
“Their wind tunnel model is almost certainly significantly quicker than the vehicle currently racing, and they will naturally want to translate that theoretical performance into physical upgrades on the track. Therefore, I am highly confident we will see updates from them. It would be fantastic for us if they didn’t, but I am not counting on that scenario…”
