Massa tops testing on final day
The Brazilian became the only driver to go under the one minute 23 second barrier when he registered a lap of 1:22.625 with less than half an hour to go at Montmelo.
The time sees Massa top the table following the completion of testing, trumping Mercedes' Nico Rosberg, who was unable to better the 1:23.168 he registered on Sunday.
Massa's team-mate Fernando Alonso ended as the 10th-quickest, over a second slower with a best time of 1:23.978.
"The outcome of testing up to the end of today has been positive," Massa said. "We really did a lot of kilometres and I think our team actually completed more than anyone else.
"Both myself and Fernando did a real and genuine race simulation and we tried all the types of Pirelli tyre with different fuel levels. Where are we compared to the others? I don’t know and until we are all doing the same things at the same time, in other words at the first race, then we won’t know for certain.
"The Red Bull is definitely very quick and that’s a fact. Today, we did a good lap time and I think we are not off the pace: however, yesterday Rosberg was quick for example and you definitely cannot rule out McLaren and some other teams."
