Explained: How McLaren and Mercedes got back together
One of the biggest talking points off the track in Sochi last weekend was the announcement that McLaren would return to using Mercedes Formula 1 engines from the 2021 season.
McLaren last used Mercedes engines in 2014, before switching to its ill-fated relationship with Honda between 2015-2017 and finally settling with a Renault deal in 2018. When McLaren announced its initial split from Mercedes in favour of Honda in 2013, Ron Dennis - who was team principal at the time - made it clear that the Woking-based team did not think it could succeed as a customer team.
