Since Honda joined forces with Red Bull in 2018—initially with their sister team, Toro Rosso—the collaboration has powered Red Bull to unprecedented heights. With Honda’s engines, Max Verstappen clinched four consecutive Drivers’ titles (2021-2024), and Red Bull secured back-to-back Constructors’ Championships in 2022 and 2023.
Honda’s involvement has evolved over the years. The Japanese manufacturer officially withdrew from Formula 1 after 2021 but continued providing technical assistance under the existing engine freeze rules. By mid-2023, Honda reversed its decision, reaffirming its commitment to the sport. However, Red Bull’s move to establish its own powertrains division for the 2026 regulations made a long-term partnership untenable.
