Mercedes has revealed the cause of George Russell's car stoppage and retirement on lap 30 of the Canadian Grand Prix, when he was leading the race.
James Allison, Technical Director: "The Canadian weekend was important for us - we brought the first major update to the car and hoped it would prove effective. This was the case, but a weekend that was otherwise exceptionally good in terms of car performance was marred by a reliability issue with George's car. George's power unit failure was caused by a battery malfunction. After a third of the race, a breakdown occurred, resulting in a retirement. After the race, we clearly saw that the battery had been severely damaged by overheating. We need to identify the exact cause and address it in the coming days." https://f1.vpesports.com/
