Lewis Hamilton‘s car stopped on track in the middle of the afternoon session of day 2 of the second pre-season test.
Mercedes identified the problem as an “oil pressure anomaly, which made the engine shut down as a precautionary measure”. In their social media post the team added: “We will keep investigating further but unfortunately that concludes our running for the day.”
It was later reported by Motorsport.com that Mercedes decided to send the affected power unit to the team’s engine HQ in Brixworth for further analysis. The report also states that Mercedes refitted the car with the same power unit that failed last week due to electrical issues. That engine was repaired and is now back in action.
Williams, who is also powered by Mercedes, had several engine related problems during pre-season testing, requiring the team to replace the engine two times already. This led to speculation that Mercedes might be having an issue with its 2020 power unit, but nothing has been confirmed.
Hamilton returned to the track in the morning session of the final day of pre-season testing.
