Hamilton Predicts Mercedes Grid Penalties Amid Battery Reliability Crisis

Lewis Hamilton has warned that Mercedes is likely facing grid penalties later in the 2026 season as battery reliability issues threaten to exhaust the team's power unit allocation. The Ferrari driver pointed to early-season retirements for both George Russell and Kimi Antonelli as evidence that the Brackley squad is burning through its limited component supply faster than planned.

Why it matters:

With drivers restricted to just three Energy Store and MGU-K units for the entire campaign, any additional battery failure would push Mercedes beyond its allocation and trigger an automatic 10-place grid drop. Hamilton, who joined Ferrari this season, sees an opportunity for the Scuderia to capitalize on its rival's misfortune, particularly as he currently trails championship leader Antonelli by 32 points in the standings.

The details:

• Russell retired from the lead at the Canadian Grand Prix with a battery failure, while Antonelli suffered an identical issue in the closing laps of the Spanish Grand Prix at Barcelona.
• Mercedes-powered customer McLaren has also encountered reliability problems this season, suggesting the issue extends across the engine supply network rather than being isolated to the works team.
• Current regulations permit a maximum of three Energy Store and MGU-K components per driver; exceeding this limit results in an immediate 10-place penalty for each additional unit.
• Hamilton praised Ferrari's SF-26 for its strong reliability record out of the box, calling it a product of improved processes and execution across race weekends.

What's next:

Ferrari will need to maximize every points opportunity while Mercedes manages its looming component crisis. Antonelli's difficult British Grand Prix—where damage forced extra pit stops and a subsequent penalty dropped him out of the points—offered Hamilton a minor reprieve. However, the seven-time champion knows consistent execution will be crucial if Mercedes' inevitable penalties materialize later in the year, potentially shaking up the championship order.
