Honda may already have regrets about pulling out of Formula 1 at the end of the year.

Earlier, the plan was simply for Red Bull to take over Honda's engine IP in order to go it alone in Formula 1 with its Red Bull Powertrains subsidiary.

But now, Honda has committed to assembling Red Bull's engines in 2022 as well as providing "trackside engineering support and race operation assistance".

Not just that, Red Bull and Honda will keep collaborating in the area of driver development as well as expanding into "various forms of motorsport".

The obvious implication is that Honda may now be aggressively back-paddling on its decision to quit Formula 1 completely at the end of this season.

"I personally think Honda will return to Formula 1," Honda's F1 managing director Masashi Yamamoto said in Turkey.
