McLaren has extended its engine partnership with Mercedes until the end of 2030 that will see them use the German manufacturer’s power unit for the new 2026 regulations.

McLaren has a long association with Mercedes in Formula 1 that stretches all the way back to 1995, with the two parties reconciling in 2021 after a seven-year split.

The Woking-based outfit had considered its long-term options as it pondered whether to remain a customer team or join forces with another engine manufacturer to become a works partner.

With the next generation power unit regulations fast approaching, McLaren confirmed it had opted for continuity and re-signed with Mercedes through to 2030.

“Mercedes-Benz have been a brilliant and reliable partner of the McLaren Formula 1 Team,” said McLaren CEO Zak Brown.

“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.

“We have been successful together, both in the last three seasons and when they previously powered the team, so we look forward to the success to come as we continue our journey to fight consistently at the front of the grid.”

McLaren and Mercedes’ previous affiliation ran from 1995 to 2014, winning the constructors’ championship and three drivers’ title in that period.

Both went their separate ways when McLaren teamed up with Honda in 2015, but, six years later, a deal was struck to work together again.

McLaren’s first season powered by a Mercedes engine saw it end a nine-year victory drought when Daniel Ricciardo won that year’s Italian Grand Prix at Monza.

“It has been a cornerstone of our motorsport strategy to work with strong customer teams,” explained Mercedes boss Toto Wolff.

“This has many advantages: it gives a clear competitive benchmark, accelerates our technical learning, and strengthens the overall F1 business case for Mercedes-Benz. McLaren have been fierce and fair competitors since 2021, especially in the second half of this season.

“McLaren’s strong performances underline the importance of transparent and equal supply to all customer teams in the sport, if we wish to achieve the goal of 10 teams capable of fighting for podium finishes.”

The extension of the relationship means McLaren will run a Mercedes power unit during the next rule reset in 2026, which will see engines run on 100% sustainable fuels and have a 50% increase in electrical power.

McLaren team principal Andrea Stella said the team’s long term commitment to Mercedes is down to having “great confidence” it will deliver a competitive power unit for the new rules.

“We are pleased to confirm a long-term renewal of our power unit deal with Mercedes-Benz into the new era of regulations,” said Stella.

“We have great confidence in Mercedes and our relationship with them. They’ve supported our journey back to the front of the grid so far, and the security and stability this partnership brings is vital in ensuring we remain on this upward trajectory.”
