Mercedes budget claim on 2026 upgrades faces doubt

BBC Sport and Autosport reported Toto Wolff said Mercedes lacks the budget to match 2026 upgrade pace, a claim McLaren has publicly questioned.

BBC Sport and Autosport reported that Mercedes team principal Toto Wolff said the team does not have the budget to develop its 2026 car at the same rate as rivals. Because the story is not confirmed in the supplied brief, that claim remains reported rather than established fact.

Autosport and Motorsport.com also reported that McLaren team principal Andrea Stella challenged Wolff’s position publicly. Separate Autosport reporting said Ferrari and McLaren have made gains with recent 2026 updates, putting more focus on Mercedes’ development path.

Autosport further reported that Mercedes technical director James Allison described the team as "out of phase" with rivals after continuing development later, which he said can create a leapfrog pattern as updates arrive at different times. As background, Mercedes is one of Formula 1’s most successful constructors with 138 wins and eight titles, while Ferrari has 250 wins and 16 constructors’ championships.
