Felipe Massa looks to have ruled out a move to the WEC once his Formula One career is over.
Earlier, the retiring Williams driver had indicated that WEC, DTM, and Formula E were his options for 2017 and beyond.
"Things are going the way I imagined and I'm happy with my decision," the 35-year-old said of his retirement decision.
"I do not want to talk much about it, but it's all going the way I wanted," he revealed.
"It's the most relaxed time of my career and I'm in no hurry" to decide what to do next, Massa is quoted by Brazil's UOL.
The report said the former Ferrari driver is in talks with 'several' Formula E teams and also has an eye on DTM, although a lack of competitive seats has effectively ruled out the WEC.
"The type of racing is the most important," Massa said. "DTM certainly has good races, and it's more competitive than WEC and Formula E.
"I'm in a position to choose where I'll have more fun and of course it's important to have a cheque to pay my bills."
