Antonelli Confirms Monza Grid Penalty Amid Mercedes Reliability Concerns

Kimi Antonelli has confirmed he will take a grid penalty at his home race in Monza after reliability issues pushed him onto his fourth power unit before the summer break. Teammate George Russell faces the same issue, leaving Mercedes to manage two inevitable penalties as the team leads both championships.

Why it matters:

Antonelli holds a 50-point lead in the Drivers' Championship while Mercedes enjoys a 72-point advantage in the Constructors', so minimizing points loss is paramount. Taking the penalty at Monza, one of F1's easiest circuits for overtaking, is a calculated move to protect a commanding position already tested by power unit failures, including Antonelli's Barcelona DNF and Russell's water leak in Hungary.

The details:

• Antonelli moved to his fourth and final allocated power unit at Spa-Francorchamps after the team identified an issue, making a penalty unavoidable if further changes are needed.
• Russell also took his fourth power unit in Hungary after a water leak ended his qualifying session early and forced a component change.
• Monza's long straights and drafting opportunities make it the preferred venue to serve penalties, a factor Antonelli specifically cited when confirming the decision to Italian media.

What's next:

Antonelli knows Italian fans will expect a strong showing at the Temple of Speed, but his priority is the championship. He admitted that while compromising his home race is frustrating, fighting back through the field at an overtaking-friendly circuit offers the best chance to limit damage. The Dutch Grand Prix this weekend offers a final benchmark before Mercedes tackles the penalty weekend at Monza.
