Mercedes team principal Toto Wolff said the team could not afford to develop its 2026 car at the same pace as McLaren and Ferrari, arguing that the cost cap left Mercedes unable to match the heavy upgrade packages its rivals have brought in recent months. Wolff said Mercedes had taken a more conservative approach, spread its upgrades across the season and made few significant updates since the Canadian Grand Prix in May, while McLaren and Ferrari continued adding new parts and pulling clear in the development race.
The pressure on Mercedes increased after McLaren’s Lando Norris won the Dutch Grand Prix at Zandvoort for his second straight victory. McLaren and Ferrari both introduced new parts there, after McLaren had made a major upgrade in Hungary and Ferrari had upgraded in Spain in June. Mercedes won the first six races of the season, but Ferrari and McLaren each won two of the next six after their upgrade programs began to pay off.
Wolff said Mercedes had not allocated its $215 million cost cap allowance in a way that let it keep up with rivals. McLaren team principal Andrea Stella said he did not believe Wolff’s financial explanation and said Mercedes would likely start turning wind-tunnel performance into track upgrades. Ferrari boss Fred Vasseur called Wolff’s criticism of Ferrari’s upgrade rate “quite ironic,” saying Ferrari had not brought more parts than Red Bull or other teams. After the Dutch Grand Prix, Mercedes drivers Kimi Antonelli and George Russell said McLaren were faster than Mercedes following the recent updates, as Mercedes tried to respond to its rival’s improved form.
