The Formula 1 paddock was rocked Wednesday by the news that Christian Horner, the longtime CEO and team principal of Red Bull Racing, has been fired after a 20-year run that featured many race wins and championships with drivers like Sebastian Vettel and Max Verstappen.

Red Bull team principal Christian Horner is out, fired after 20 years at the helm of the F1 racing team that's won six Constructors championships with him. And it's the end of an era with his partnership with Max Verstappen, not because the four-time champion is leaving for Mercedes (yet?), but because Horner won't be leading the team anymore.

Red Bull Racing announced Wednesday that CEO Christian Horner is departing the team after 20 years at the helm.
