McLaren to return to Mercedes engines in 2021

McLaren will return to using Mercedes engines in 2021, switching from current partner Renault after just six seasons away from the German manufacturer.

McLaren have struck a four year deal with Mercedes to use their engines until at least 2024.

McLaren and Mercedes saw success in their previous partnership, winning three drivers' titles together, twice with Mika Hakkinen in 1998 and 1999 and then with Lewis Hamilton in 2008.

For the most part, their partnership produced a car capable of winning races, before McLaren made the brave decision to switch to Honda, a choice that didn't pay off, as they struggled for power for three years before moving to current supplier Renault.

McLaren Racing and Mercedes-Benz announce that the McLaren F1 team will be powered by Mercedes from 2021 until at least the 2024 season under a long-term agreement.

McLaren CEO Zak Brown said: “This agreement is an important step in our long-term plan to return to success in Formula 1. Mercedes is the benchmark, both as a team and a power unit, so it is natural we would seek to secure a relationship with the company for the next phase of our journey.

"This announcement reflects the confidence of our shareholders and is an important message to our investors, our team, partners and fans that we are committed to returning McLaren to the front of the field.”
