Felipe Massa will be given a new chassis for this weekend's Malaysian Grand Prix as his Ferrari team bids to get to the bottom of his troubles in Australia.
The Brazilian had a disappointing weekend in Melbourne, being comprehensively outqualified by teammate Fernando Alonso and enduring an incident-filled race before his retirement.
Although the team continues to have faith that Massa can turn his situation around, it has elected to change his chassis with immediate effect. For this weekend in Sepang he will race with chassis number 294, to see if the car was a factor in his performance.
A statement on the team's website said: "This choice was taken to clear up any doubts about the unusual performance of his car during the weekend at Albert Park."
