I can imagine teams need to approve an in season change but I can't see restrictions on next year.
Andi.
The deadline for confirming your engine for next season passed a few weeks ago. They said at that time Honda. If they want to change I believe, although I haven't seen it confirmed anywhere, they need agreement of all the teams. Which is far from guaranteed.:Yeahthat: Can't see it being a mid season change, otherwise Honda would probably want their large lump of money back. Imagine it'll be from next season.
