Reliability issues have hit Mercedes and Kimi Antonelli on the final morning of F1 pre-season testing.
Kimi Antonelli brought out the red flag during F1 pre-season testing at Bahrain International Circuit when his Mercedes stopped after Turn 10 due to an energy deployment issue.
Before the incident, Antonelli had a strong morning and completed 49 laps, holding the second-fastest time of 1:33.916, only slightly behind Charles Leclerc.
Despite the setback, Antonelli still boasts the fastest time of the Sakhir tests with a 1:32.803 set the previous evening.
George Russell is set to take over the wheel from Antonelli for the final day of testing at lunchtime, with Mercedes continuing as pre-season favorites despite power unit controversies.
