Four-time world champion Sebastian Vettel emerged as the fastest driver for the second day in succession at the pre-season Formula One testing in Jerez on Monday.
The German, who switched to Ferrari from Red Bull over the winters, completed 88 laps to finish almost one second clear of his opponents.
While the second-fastest time of the day went to Sauber's Felipe Nasr, reigning world champion Lewis Hamilton clocked 91 laps, the most by any driver, despite a reliability issue, the BBC reported.
However, McLaren-Honda's testing session got interrupted again due to ancillary problems as Jenson Button could only manage to drive six laps.
