Following the early afternoon Qualifying session in Santiago's Parque O'Higgins, where Lucas di Grassi clinched a provisional Pole while under investigation, the FIA - motorsport's governing body - found the Brazilian driver to be in breach of a new rule, sending him to the back of the grid for the race start.
Brought in after the pit lane incident in Marrakesh, where NIO's Tom Dillmann crashed into the back of the Envision Virgin Racing cars, di Grassi was found to have used his brakes more in the "inlap" during Qualifying then in the flying lap without any reason.
As a result, the Brazilian falls to the back while old rival Sebastien Buemi will start the race on Pole.
