Mercedes Team Principal Toto Wolff says the team’s reliability problems are not acceptable and limit its ability to compete for major results. Speaking after Kimi Antonelli’s late retirement at the Barcelona-Catalunya Grand Prix, Wolff criticizes Mercedes’ performance in maintaining cars through to the end of races. According to Wolff, the reliability issues cost the team potential points and undermine championship aspirations. He characterizes the current level of reliability as “just not good enough” and also argues that Mercedes cannot realistically contend for a championship while such problems persist. The reports describe the Barcelona race as another instance where Antonelli is forced to retire late, turning a likely strong result into lost points. Mercedes’ reliability concerns therefore remain a central focus as the team evaluates what must improve to reduce late-race failures and restore competitiveness. The statements reflect a direct assessment from the team leadership that reliability must improve for the team to challenge for top-season targets.
