Russia

Sochi tightened the title picture without resolving it. de Vries took pole, but the Feature went to Albon, who passed Russell early and emerged ahead of de Vries after the pit stops to win by over eleven seconds in a DAMS one-two with Latifi, who took second from de Vries with a few laps left after the Prema man locked up heavily. Markelov ran as high as the lead before a slow stop dropped him to eleventh. Norris's title hopes took a blow when he retired after his Carlin pit crew failed to attach a wheel properly. The Sprint, run in changing conditions, went to Russell, who dominated and set fastest lap by over seven seconds. A sudden mid-race downpour saw the frontrunners pit together for wets, while Fuoco and Delétraz gambled on slicks and lost out, and a safety car was triggered when Lorandi ran into the back of Latifi. Norris, given a stop-and-go penalty, then retired after contact with Maini gave him a puncture — an exit that formally ended his championship bid and dropped him to third behind Albon. Russell left Russia leading by thirty-seven points, the title still mathematically open into the finale.
