Two regular season rounds of this year’s FIA World Endurance Championship will be run at night, it has been confirmed.

The FIA WEC announced the starting times for all seven of its six-hour events, with the American race set to take place from 4:30-10:30 p.m. on Sept. 20.

It will run on the same day as the TUDOR United SportsCar Championship race following a reshuffle in the event’s weekend schedule.

The Six Hours of Bahrain, meanwhile, will again run from 3-9 p.m., which will feature more than four hours of night running time.

Additionally, the Spa, Fuji and Sao Paulo rounds will all finish in dusk conditions.

While not yet officially announced, the double points-paying 24 Hours of Le Mans is expected to again have a 3 p.m. start time.
