The German manufacturer has admitted to facing reliability issues with its internal combustion engine that have already forced both the works team and its customer ou🐲tfits to take grid𒆙 penalties. 

Valtteri Bottas has used six ICE elements, while teammate Hamilton had a grid penalty at the Turkish Grand Prix after switching onto his fourth V6 of 💦the campaign. 

Merc🉐edes has been introducing fresh internal combustion enginesꦐ amid fears it could suffer a failure that could have “catastrophic” consequences for its championship prospects. 

Speaking on Friday 🐲at the Mexico City Grand Prix, Mercedes boss Toto Wolff provided a positive update,🐟 revealing the team believes it has now got to the bottom of its problems. 

“I think we're feeling more robust about one particular issue that se🔯ems to bꦑe solved,” Wolff said. 

Wo♈🦂lff ruled out either Mercedes driver taking any further engine penalties in Mexico due to the difficulties of overtaking, citing Bottas’ struggles to make progress in the United States Grand Prix. 

“I ꩵthink it's never right ♌to take a penalty, because these days it's so difficult to overtake,” he explained. 

“You can see that Valtteriಌ was a꧑bsolutely dominant in Turkey, but you just get stuck in traffic with the penalty [in Austin]. 

“So we'𒉰re taking it on the fly. We're deciding, do we need the penalty or are we not needing a penalty? And here certainly we won't take one.

“And maybe we don't need any until the end of the season. Tဣhat is really something th🏅at is being discussed.”

Hamilton, who trails Red Bull’s Max Verstappen by 12 points in the world championship, stressed ahead of the weekend that Mercedes is a🅷iming to stick with his current pool of engines for the remaining five events. 

“I believe our engines are strong and as far as I am aware we are hopefuไlly going to t🅘he end,” Hamilton said. "So that is not going to be an issue for us hopefully."
