Red Bull and Alpha Tauri team’s engine manufacturer Honda have announced that it will not be a part of F1 after the end of 2021 season.
Both the F1 teams earlier split up with engine manufacturer Renault for Honda engines. In 2018 Honda supplied engines to Toro Rosso sister team of Red Bull Racing before supplying engines to them as a works team.
Honda entered the f1 business in 2015 as an engine manufacturer for Mclaren Team, which ended in a sour note due to their innumerable reliability issues.
However, Honda has decided not to continue beyond their current arrangement with Red Bull and AlphaTauri, which exists until the end of next year.
That will leave Formula 1 with three power unit suppliers – Mercedes, Ferrari and Renault. Under the current rules, Renault would be obliged to supply Red Bull and AlphaTauri with engines as they currently have the fewest customers, unless the teams can convince Mercedes or Ferrari to supply them.
Red Bull and Alpha Tauri have recently committed to the new Concorde Agreement, which binds them to the F1 Championship until the end of 2025.
