The venues for the four pre-season tests have been revealed, with the Superleague teams visiting three continents ahead of the season start.
The four testing venues have been announced as Sakhir (1st February), Sepang (8th February), Imola (15th February) and Mexico City (22nd February),
Superleague teams will take part in all tests as they begin acquiring data to start development at the end of February.
The top flight's outfits won't be the only ones on track ahead of the season, however. Supercup teams will be testing on the Wednesday preceding the final two tests, while Formula Challenge entrants will get their first taste of official 2018 action on the Tuesday of the final week of testing.
