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. Zolder became the season opener instead of Misano. On 17 September 2017, it was announced the race at Silverstone was moved a week to avoid a clash with the Nürburgring 24 Hours. On 9 October 2017, the finalised calendar was announced, confirming the dates of the races at the Hungaroring.;Race format
In previous years a Sprint race weekend consisted of one Qualifying session, one Qualifying Race - of which the results set up the grid for the Main Race - and one Main Race. On 2 October 2017, changes to the format of Sprint race weekends were announced. In 2018 a Sprint race weekend consisted of two races scoring equal points and featuring separate Qualifying sessions for each race.
