Bottas triggers first red flag on final day of Bahrain testing

Valtteri Bottas brought the morning session of Formula 1's final pre-season test day in Bahrain to a halt after his Cadillac stopped on track. The stoppage in the second sector caused the first red flag of the day, mirroring an incident from his teammate Sergio Perez just 24 hours earlier.

Why it matters:

Reliability issues during testing are a critical red flag for any team, and for Cadillac to have both drivers cause stoppages on consecutive days raises immediate questions about their early-season preparation. With the first race just days away, any significant lost track time limits a team's ability to validate their car and finalize setups, potentially putting them on the back foot from the opening round.

The details:

• The Incident: Valtteri Bottas brought out the red flag when his Cadillac came to a stop towards the end of the second sector during his run.
• Limited Running: At the time of the stoppage, the Finnish veteran had completed only eight laps and was sitting eighth on the timing sheets.
• Session Leader: George Russell continued to set the pace for Mercedes, topping the session with a lap time of 1:34.075, ahead of Max Verstappen's Red Bull.
• Team Trend: The incident follows teammate Sergio Perez causing a red flag during his own running at the Bahrain circuit on the previous day of testing.

What's next:

The focus for Cadillac will be diagnosing the issue with Bottas's car and returning to the track as quickly as possible to maximize the remaining test time. Teams have just this final day in Bahrain to gather data before the cars go into parc fermé for the opening Grand Prix weekend. Any unresolved reliability concerns now could translate into race-day vulnerabilities next Saturday.
