Honda made an official announcement in May 2013 that it planned to re-enter into Formula One in 2015 as an engine supplier to McLaren. In September 2017, after a winless campaign spanning three seasons and achieving a best finish of fifth place, McLaren and Honda announced their split, with the latter going on to sign a multi-year deal to supply Toro Rosso, the junior team of Red Bull Racing. After a fairly successful season with Toro Rosso, Honda made a deal to also supply Red Bull Racing. Max Verstappen scored Honda's first win of the V6 turbo-hybrid era at the Austrian Grand Prix. In October 2020, Honda announced that they would be leaving Formula One at the end of the 2021 season.
