Felipe Massa admits he is surprised by the gap between Mercedes and Williams following qualifying for the Australian Grand Prix.
Lewis Hamilton took pole position from team-mate Nico Rosberg, with the two Mercedes cars separated by 0.6s. However, Massa was a massive 1.4s back in third place despite Williams also using a Mercedes power unit, and he says the deficit must be in the chassis as a result.
"If we have the same engine, the difference should be in the car - so I hope we have the same engine!" Massa said. "I believe we have the same engine, so it must be the car ... maybe."
When it was put to Massa that the gap to Mercedes seemed to be bigger than in 2014, the Brazilian replied: "Yes it is and for sure it is not great to see this difference but we'll keep working, keep fighting, and I hope we can get as close as we can."
Looking ahead to Sunday's race, Massa expects he and team-mate Valtteri Bottas will be closely matched with the Ferraris in the battle for the final podium position.
"It was a very tricky qualifying especially when you have four cars fighting for very similar times all the time. If you see the difference in lap times between me, Sebastian [Vettel], Kimi [Raikkonen] and also Valtteri, it's pretty small but I'm happy.
"It will be a big fight tomorrow, with Ferrari especially, and I hope we can do a good job."
