Honda motorsport boss Yasuhisa Arai says it is 'too late' to secure a deal to supply engines to Red Bull for next season, fueling belief Red Bull may re-sign with current power unit supplier Renault.

The ongoing saga surrounding Red Bull's engine crisis has seen the team speak to Mercedes, Ferrari and Honda about a deal for power units in 2016 after falling out with Renault and requesting to terminate its contract a year early.

However, Mercedes declined supplying to a main rival while negotiations with Ferrari and Honda have both stalled, with McLaren chief Ron Dennis also saying he'd block Honda from supplying Red Bull, and Arai has confirmed time has run out to secure a deal.

"I think it's too late. Even if we got the offer right now, it's too late," Arai said. "Always we concentrate on McLaren-Honda as the works team and there is no change."

With three of the four major engine suppliers effectively ruled out Red Bull looks set to remain with Renault but no deal has been confirmed yet, despite the team stating it will be on the F1 grid in 2016.
