The FIA WEC is in the process of putting together a ‘Plan B’ for their Season 8 Calendar with as-yet undisclosed issues at Interlagos putting the Brazilian round at significant risk.

The FIA WEC teams were informed of the potential for a change, though with no specifics for the underlying reasons, in Shanghai on Thursday.

The race, set to take place on 1 February, would be replaced if the fixture falls with Championship organisers currently working on other alternatives, very likely on the same date.

Paddock sources have suggested that a number of potential alternative venues are being considered with the available freighting routes and schedules being a primary factor informing the options.

Mexico City, Kyalami and CoTA are all understood to have been considered with varying degrees of seriousness.

The final decision is due to be taken within the next two weeks.

No response was given after a request from DSC for comment on Friday, or since.
