Christian Horner has responded to rumours that Honda, who made the decision to leave F1 at the end of 2021, could be planning a return.
Horner's team still use Honda engines thanks to a parting agreement that has resulted in the Japanese car company supplying power units to the team until the end of the 2025 season.
In the meantime, Red Bull are gearing up to build their own engines for the 2026 season with progress being made at their new Powertrains facility in Milton Keynes.
"We opened the Red Bull powertrain building earlier this week, so some of the staff moved into the building," revealed Horner, speaking to select members of the media, including RacingNews365.com.
"It is a facility that should hopefully enable us to produce really competitive engines, starting from 2026."

Horner: There's been no talks with Honda
But the Red Bull team boss says he has held no discussion with Honda regarding a return to Formula 1 for the car company.
A return for Honda could coincide with the entry of Porsche, who have signalled their intentions to arrive on the F1 scene in time for 2026.
"We have an engineering partnership, an agreement with Honda to supply the current engines under the current agreement to the end of the 2025 set of regulations but there's certainly been no discussions with us about that," Horner made clear.
"And of course, you know, there's discussions of Porsche now looking at entering the sport, which I think is really exciting for Formula 1 to have brands like that want to come in.
"But again, that is subject to what are the regulations going to be and what is the treatment of a newcomer going to be, some of those aspects."
