Formula 1 veteran Felipe Massa says he wants to race in Formula E when his F1 career comes to an end.

The Williams driver retired last year but came straight back out of retirement following Valtteri Bottas’ shock exit from the team.

Massa has previously said he wants to remain in F1 for 2018 but reports suggest he is facing stiff competition from Sergio Perez for the second seat alongside Lance Stroll who is expected to remain with the team for a second year.

“Formula E. But I don’t know when,” said the Brazilian when asked where he would go if he didn’t continue with Williams.

The 36-year-old tested for Jaguar after his first F1 retirement announcement and he was impressed.

“I did a test with them,” added Massa. “When I decided to stop F1, I was talking with some teams and with Formula E.

“I wanted to see the car, I wanted to drive the car and see how it is. I did a test with them just to see how it is.

“You cannot compare [it to Formula 1]. It’s completely different but it is still a competition.

“[There are] some great ideas for the future and the championship is growing.

“I think it’s fantastic [that new manufacturers are entering], and I see a big future in that category for a driver, especially after F1.”
