Toto Wolff says Mercedes faces championship struggles with reliability issues

Toto Wolff expressed concerns over Mercedes' ability to compete for the championship due to ongoing reliability issues following Kimi Antonelli's retirement at the Barcelona-Catalunya Grand Prix. Antonelli was running second before his car shut down late in the race, marking the second power unit failure in three races for Mercedes. Wolff indicated that consistent failures prevent the team from accumulating crucial points, and raised the importance of resolving these issues. Antonelli's departure from the race reduced his lead in the Drivers' Championship over Lewis Hamilton, who secured his first win with Ferrari this season.
