[1] Santiago had always been expected to host the third round of the 2018–19 championship, but the race remained without an assigned location while FE and city officials negotiated terms for the electric championship to return and hold a second event, following the success of the inaugural race.

However, a new layout was made necessary, after logistical challenges were encountered at the inaugural race, which faced intense opposition from local residents due to its use of roads through Santiago's Forestal Park.

The original layout of the circuit was a 14 turn, 2.348 km (1.459 mi) long track, and consisted of the roads inside of the O’Higgins Park, running around the Movistar Arena.

[3] During the second running of the race at the Circuit, the 2020 Santiago ePrix, numerous changes to the track layout were made, most notably at the curving back straight, where the tight chicane was removed, while the pit lane was moved to the other side of the track, to the inside of the circuit.

The final sector of the lap was also removed, with the zig-zag section of the track being reversed compared to the previous year.
