McLaren CEO Zak Brown says that Mercedes are feeling bullish over the reliability of their power unit ahead of the 2022 Formula 1 season.

McLaren, who teamed up with Mercedes last year had a solid 2021 season, with Daniel Ricciardo and Lando Norris scoring a 1-2 finish for the Woking-based outfit in the Italian Grand Prix.

And Brown believes Mercedes are happy with the reliability of their power unit for the upcoming season.

This was an area of concern for Mercedes in the past campaign, with both Lewis Hamilton and Valtteri Bottas suffering multiple grid penalties.

“They’re feeling good about their development,” Brown told

“We, fortunately, had good reliability last year. As you know, there’s more than just the power unit that goes into the reliability.”

Brown went on to say that he feels that his McLaren team did well working with the Mercedes power unit last year, which saw the Woking-based outfit end the season as the highest-placed Mercedes customer team, ranking P4 in the Constructors’ Championship while Aston Martin and Williams ended the season in P7 and P8 respectively.

“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,” Brown added.

McLaren ended 2021 behind Ferrari in the Championship, however, their results on track show that as a team they made significant progress, which they will be hoping to carry forward into this season as Formula 1 embarks on a new chapter in its history with the introduction of new technical regulations.


The Woking-based outfit has a lot to look forward to in 2022, not only are there new technical regulations in Formula 1 but the sport will race in Miami for the first time, while McLaren as a racing organisation will make their eagerly anticipated Extreme E debut.

Meanwhile on the IndyCar side of the team, ex-McLaren F1 driver Juan Pablo Montoya will return to the team for the Indianapolis 500 in May.

McLaren will launch their new Formula 1 car, the MCL36, on Friday 11 February.
