Massa insists Ferrari will continue to fight, even though the titles may already be out of reach.
"Maybe for Red Bull it is not over yet, but for us, we are completely behind in the championship," added Massa, who has won the last three races in Istanbul.
"Brawn have a really competitive car with which is easy to score points. So even if we win as many races as possible, they are going to be there.
"That doesn't mean we won't fight in every race to win. We will fight until the end. Mathematically, it's still possible but it's difficult.
"I'm not the kind of guy who gives up very easily, so I'll fight until the last corner of the last race."
Button expects Ferrari and Red Bull, the only other team to have claimed a race victory this season in China, to push him hard in Turkey.
The fast and flowing circuit is particularly expected to suit Red Bull, who will want to see more performance gain from the advantageous double diffuser they fitted to their cars for the first time in Monaco.
"The Red Bulls will be competitive here," said Button. "They're quick enough to fight with us that's for sure.
"The Ferraris will be quick here too. They've made up ground at every race and they performed very well, especially in Monaco.
