Webber grabbed Red Bulls first chart topper on the first day of the last test session setting his time of 1m22.693s of the soft tire.
The Australian set his fastest time of the day in the afternoon after heavy rain had blighted the morning session. Lewis Hamilton was second fastest for Mercedes, with Jean-Eric Vergne third for Toro Rosso.
