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 team-mate 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, the outfit has elected to change his chassis with immediate effect – so for this weekend in Sepang he will race with chassis number 294 - to see if it 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."
