The Woking-based team’s current contract ran until the end of 2025, and it had been evaluating its options for the longer term.
But, ahead of the F1 season finale in Abu Dhabi, McLaren announced that a new five-year deal was in place.
McLaren has been a partner of Mercedes since 2021, having previously enjoyed a period of world championship success with the company in the late 1990s. It remains the most recent customer winner in F1, with Daniel Ricciardo’s triumph at the 2021 Italian GP.
Speaking about the decision to commit to Mercedes, McLaren CEO Zak Brown said that the length of the deal was evidence of how much trust his team had in Mercedes’ products.
"Mercedes-Benz have been a brilliant and reliable partner of the McLaren Formula 1 team,” he said.
“The extension signifies the confidence that our shareholders and the wider team have in their powertrains and the direction we're taking with them into the new era of regulations ahead.
