Antonelli Confirms Mercedes ERS Fix for Austria After Battery Failures

Kimi Antonelli confirmed that Mercedes is introducing a major reliability upgrade at this weekend's Austrian Grand Prix after battery failures derailed the opening rounds. The new Energy Recovery System (ERS) pack targets durability over performance, as the manufacturer fights to contain a crisis affecting all Mercedes-powered teams.

Why it matters:

The recurring failures have cost Mercedes and its customers critical points. Antonelli retired from second in Barcelona after overtaking George Russell, while Russell dropped out while leading in Canada. McLaren's Lando Norris has also suffered race-ending battery issues, exposing a systemic power unit flaw threatening title hopes across the customer network.

The details:

• Antonelli told select media the upgraded ERS pack targets durability and reliability, stressing the failures have not always been tied to temperature spikes.
• The package marks Mercedes' first major response to the battery crisis, with Antonelli running it at the Red Bull Ring.
• Every Mercedes-powered squad has suffered failures across the opening seven rounds, with multiple retirements suggesting a deep-rooted energy store flaw.

What's next:

The Austrian Grand Prix becomes a high-pressure proving ground for the new hardware. If the ERS fix holds, Mercedes can shift focus back to closing the performance gap. Until the team proves the reliability is solved, however, question marks will linger over every Mercedes-powered entry on Sunday.
