Felipe Massa's father says it is possible the retiring Formula 1 driver will switch to another category in 2017.
Massa, 35, announced at Monza that he will not be extending his long F1 career into a sixteenth consecutive season next year.
But his father, Luis Antonio, told Sportv: "He could race somewhere because that's what he loves to do. In a top category, no doubt, with a chance to be champion.
"There are some options," Massa snr revealed. "WEC, DTM, Formula E. No choices are made, but it will not be other than those three categories."
