SOCHI, RUSSIA - Lewis Hamilton set the fastest time in the second practice session for the Russian Grand Prix, while Sebastian Vettel was second despite stopping his Ferrari on the track on Friday.
Ahead of qualifying on Saturday, both practice sessions were topped by Mercedes, underlining the dominance of a team which has been on pole for 39 of the last 41 races.
Hamilton edged Vettel by 0.652 seconds in the second session, and set the fastest time over the two sessions.
Hamilton’s teammate and the championship leader, Nico Rosberg, was top in the first session but third in the second, .867 seconds behind Vettel. Rosberg has won all three races.
Vettel was fast early on but came to a halt on the start-finish straight just before the halfway point of the 90-minute session, saying over the team radio he “lost electronics.”
Despite losing valuable running time, Vettel was upbeat.
“The feeling was all right, the balance wasn’t yet where I want it to be, but we can improve,” he said, adding that Sochi’s Olympic Park was “a circuit which should come our way.”
