Honda will continue to supply Red Bull's 2022 power unit from its base in Sakura, despite the Japanese engine's decision to leave Formula 1 at the end of the year.
Red Bull is building its own engine development facility at its Milton Keynes factory to take over the running of the power units, but the actual power unit itself will come from Japan.
"Red Bull and Honda have been working on that project and how to proceed that transition for next year,” Honda’s technical director Toyoharu Tanabe told RacingNews365.com and other select members of the press.
“I cannot tell the detail but generally we are going [in] a good direction. We should prepare well for next year so now we are working very hard [and] I am working very hard at the trackside.”
Even though Honda have had a highly successful season with Red Bull and AlphaTauri, leading the Drivers' and Constructors' Championships after nine rounds, they will not reverse their decision to walk away from F1 after the current season.
Red Bull team principal Christian Horner has stated the team’s new powertrains operation will take over assembly of the engines after the 2022 F1 season.
“Obviously as we gear ourselves up within Red Bull Powertrains, 2022 will be a transitionary year,” said Horner.
“So we’re working with Honda to have a have a soft landing where the engines will continue to be assembled in Sakura in 2022 before that process [is] taken on in our new facility in time for 2023.”
