McLaren again used Mercedes engines in after their deal with Renault ended. McLaren had previously collaborated with Mercedes from 1995 through 2014. Daniel Ricciardo moved from Renault to partner Lando Norris for the 2021 Formula One World Championship on a multi-year deal. Ricciardo replaced Carlos Sainz, who moved to Ferrari. In the season's first nine races, the team scored three podiums with Mercedes power, in Italy, Monaco and Austria, all courtesy of Norris.
