Mercedes has confirmed that all six of its Formula 1 power units 💝at this weekend's French Grand Prix are its latest specification that had been due in Canada earlier this month, acting as a boost to Lewis Hamilton's title battle against Ferrari's Sebastian Vettel.

Mercedes had intended to intro൩duce its updated power unit to both its factory team and its customers - Williams and Force India - in Canada when Renault, Ferrari and Honda all introduced their new specification engines, only for it 🌠to be delayed due to a quality issue.

It was confirmed ahead of Friday practice at Paul Ricard that all of the Mercedes, Williams, and Force India cars had received fresh power units ahead of the race wee✱kend, with the German manufacturer later making official that they are the updated specification with some "added goodness" beyond what was pl🧸anned for Canada.

"All six Mercedes-powered cars were fitted with fresh ICE, Turbocharger and MGU-H for this weekend. Those new co𒐪mponents are of an upgraded s🦩pecification which contains reliability and performance updates," a Mercedes spokesperson confirmed.

"While we would have had a Phase 2 in Cnaada, this is a Phase 2.1 with some '𒁃added goodness' thanks to a fantastic effort by the team in Brixworth. Since Canada, they have reworked six race units plus sparꦆes, all of which are on site.

"We plan to con🌼tinue running these PUs for the rest of the race weekend."

Mercedes works driver Hamilton was left on the backfoot compared to his Ferrari and Renault-powered rivals in Canada, struggling to a fꦅifth-place fini𝄹sh in the race as Sebastian Vettel moved back into the drivers' championship lead with a comfortable victory.

Hamilt🌠on impressed for Mercedes through practice on Friday at Paul Ricard, leading both FP1 and FP2 with an advantage of seven-tenths of a second come the end of the day.
