Calendar
At the annual press conference during the 2017 24 Hours of Spa on 28 July, the Stéphane Ratel Organisation announced the first draft of the 2018 calendar. Initially, no changes were made to the schedule compared to 2017. On 27 September 2017, it was announced the races in Buriram were moved one week earlier to avoid a clash with the 3 Hours of Silverstone. On 29 January 2018, it was announced Ningbo would replace Zhejiang as the final round of the season.
