Currently, Mercedes supplies the most teams, including Aston Martin, McLaren, and Williams, in addition to their own team. This multi-team approach provides various advantages, particularly financial ones. Horner revealed that Red Bull Powertrains has designed its facility to accommodate up to four teams in the future, indicating their long-term intentions.
Their current emphasis, however, is on building a cohesive team, integrating the engine division with the chassis team, and making substantial progress in this challenging endeavor. Red Bull’s aspiration is to be a formidable force in engine supply within Formula 1 while taking measured steps towards expansion.
