February 2, 2015 – Sebastian Vettel topped Formula 1 pre-season testing at Jerez for the second day running in the Ferrari SF15-T.
The four-time world champion set several laps faster than anyone else during two medium-tyre runs in the morning, and his position at the top of the times was safe once a rain shower hit the track with an hour of running remaining.
Sauber used soft Pirelli tyres to take the runner-up spot for the second day running, with Felipe Nasr edging out Williams’s Valtteri Bottas when both were lapping on the yellow-sidewalled tyres at the same time in the afternoon.
Mercedes topped the lap count again, but Lewis Hamilton’s his day was cut short when a water leak forced him to stop the F1 W06 in the pit entry.
McLaren and Red Bull also endured troublesome days, with Jenson Button only completing six laps for the former and Daniil Kvyat failing to post a time for the latter.
