As previously reported, Bernie Ecclestone has made to clear that the Hockenheim promoter does not want to pay the fee that he has proposed, having given the race a special deal in 2016.

Hungary is now expected to move from July 23 to the original German date of July 30, mainly because without that change there would be a break of four weekends with no races.

The other changes are under discussion which will move the 2017 schedule closer to this year's, although they will not become official until the WMSC approves them.

Malaysia had been placed on its own in a swap with Singapore, leaving the latter back-to-back with Japan.

It is understood that this will probably be reversed so that Singapore is once again a standalone event.

Austin had been on its own in the provisional calendar, with Mexico and Brazil placed together. However, Mexico is set to be moved so it is paired with Austin once more.
