JEREZ, Spain (AP) -- Sebastian Vettel's career with Ferrari is off to an encouraging start, with the German driver quickest in Formula One pre-season testing for the second day running.
The four-time champion joined Ferrari after a miserable season with Red Bull last year. The German finished fifth overall, failed to win a race and secured only four podium finishes compared to 13 Grand Prix wins the previous season.
Vettel clocked a best lap of 1 minute, 20.984 seconds on Monday -- almost two seconds better than he managed on Sunday.
Sauber driver Felipe Nasr of Brazil was second best in 1:21.867 and Williams driver Valtteri Bottas of Finland third quickest in 1:22.319.
Defending champion Lewis Hamilton was fourth fastest in Mercedes and cut short his session about an hour before the end.
