Felipe Massa is weighing up a move into DTM, Formula E or the FIA World Endurance Championship for 2017 following his retirement from Formula 1 at the end of the season.
Massa announced over the Italian Grand Prix weekend that the season-ending Abu Dhabi Grand Prix would be his final start in F1, bringing the curtain down on a 15-year stint in the sport.
However, the Brazilian plans to keep racing, with his eyes set on a European-based championship for 2017 instead of a move into IndyCar or Brazilian stock cars.
"I have some people [interested for 2017] but I just need a bit of time to think about it and to decide in the best way," Massa told reporters in Singapore on Thursday.
"I will race. I just need to understand what will be the right choice [so] that I will keep enjoying [racing] and having fun.
"I don't think it will be stock cars. Not IndyCar.
"I think maybe it will be DTM, WEC, Formula E – maybe one of these three I think."
