Red Bull has launched its 2021 Formula 1 challenger, revealing the first images of the RB16B.

The team finished second in the constructors' standings to Mercedes last year, with Max Verstappen the last non-Mercedes driver standing in the title fight.

Verstappen is joined by Sergio Perez at the team after Racing Point - now Aston Martin - elected not to continue its relationship with the Mexican.

Perez is the fourth different driver to partner Verstappen at Red Bull in as many years after Daniel Ricciardo, Pierre Gasly and Alex Albon, the latter now in position as reserve driver for the team.

Due to the large amount of technology carried across into this year's car from its 2020 predecessor, Red Bull elected to break from tradition and label its '21 model the RB16B as opposed to the RB17.
