Lewis Hamilton will utilise the second power unit of his season allocation after suffering a component failure in qualifying for the Chinese Grand Prix.
The reigning world champion will start Sunday’s race from the back of the grid after being hit with an ERS issue, which prevented the Brit from posting a time in qualifying.
Mercedes has since confirmed that Hamilton’s problem was caused by an MGU-H issue which has prompted an engine change ahead of the race.
Hamilton had headed into the weekend with a five place grid penalty following a gearbox change.
Already 17 points adrift of team-mate Nico Rosberg, who will start from pole position, the Brit remains upbeat despite the blow.
“It was going to be a tough weekend anyway with the grid penalty,” said Hamilton.
“But these things are sent to try us. No one wants it easy – at least I know I don’t. We might be in the mud right now – but we’ll dig our way out.
“We’ve got a great car and the team are doing a great job. There are areas we can improve but it’s still early in the season and I know we’ll get there.
“It’s important that nobody lets their head drop. The best thing we can do is learn from it and move on.
“I’m sure the guys are just as gutted as I am but what will be, will be. We win and lose together, so we’ll work hard to figure out what happened and try to make sure it doesn’t happen again.”
