Zak Brown has spoken about Mercedes’ progress in developing the engine ahead of the 2022 F1 season.
Mercedes faced issues with the reliability of the internal combustion engine in the second half of the 2021 season, which resulted in grid penalties for both Lewis Hamilton and Valtteri Bottas.
At the same time, McLaren had not had issues with the Mercedes power unit. Furthermore, Brown states that Mercedes have found a solution to the problem.
“They [Mercedes] are feeling good about their development,” the McLaren CEO told Autosport.
“We fortunately had good reliability last year. As you know, there’s more than just the power unit that goes into the reliability.
“I think our guys did a good job of working with the power unit in year one, so reliability hasn’t been maybe the same level of concern with us that it has with others.
“I spoke with Toto [Wolff, Mercedes team boss] last week about it. And he was pretty bullish.
“I think the power unit race is as close as ever, but I’m not worried about it.”
