The Copper X Prix is being held in the Atacama Desert, a location chosen in conjunction with event sponsor Antofagasta Minerals to highlight the issue of sustainable mining.

Then, at the double-header in Sardinia, the orange car with the Kiwi heritage was third in free practice but posted a DNF in the first qualifier.
Hopes of another Crazy Race win were dashed when Gilmour had a crash just metres from the start line.
Following an impressive rebuild by the team, both drivers put in solid performances in the Odyssey 21 vehicle but failed to make it into the last race of the weekend.
Rosberg X Racing, winner of two of the first three X Prix, can go close to sealing a second championship title this weekend.
