Former drivers’ world champion lays down a marker in Barcelona.
Mercedes’ British driver Lewis Hamilton set the fastest time on the third day of pre-season testing in Spain.
The British Mercedes driver, world champion in 2008, posted a quickest time of 1min 20.55sec on a dry track, over a second faster than Mexican Sergio Perez’s fastest lap on the same circuit a week ago.
Germany’s Adrian Sutil was second-fastest in a time of 1min 21.627sec in his Force India, while Brazil’s Felipe Massa was third in a Ferrari.
Quickest on Friday, France’s Romain Grosjean did not take to the track on Saturday morning but was due to participate in the afternoon session.
The four-day testing session ends on Sunday ahead of the start of the 2013 season in Melbourne on March 17.
