Horner created Red Bull Powertrains before the implementation of the 2026 regulations after Honda initially chose to leave Formula One. However, Honda later decided to return under the new rules and entered into an exclusive partnership with Aston Martin. The 2026 season will bring about one of the biggest changes yet to Formula One’s rulebook. The updated engine regulations will see power distribution shift from 20/80 electrical-to-combustion to an even 50/50 split. Additionally, the MGU-H will be phased out, and teams will transition fully sustainable fuels.
