Mercedes have revealed that “high-voltage control electronics failure led to a permanent loss of MGU-K drive” on both their cars at the Canadian Grand Prix.
Nico Rosberg and Lewis Hamilton looked set for a battle royale for the race victory in Montreal, but the latter reported a loss of power on the 37th lap and it wasn’t too long before his team-mate had the same issue.
Both continued to push hard and Hamilton tried to overtake Rosberg, but he made a mistake went sliding off and then reported problems with his breaks. He nursed his car back to garage, but had to retire.
Rosberg continued and although he managed to pick up his pace, but he was eventually caught by Red Bull’s Daniel Ricciardo on the penultimate lap and had to settle for second place.
