Felipe Massa will be making his return to motorsport in next season's ABB FIA Formula E Championship.
The Brazilian has signed a three-year deal with Monaco-based outfit Venturi, which is co-owned by Hollywood star Leonardo Di Caprio.
Massa will enter the Championship in Season Five when Formula E relaunches with its futuristic new Gen2 car which will see the drivers take to the street tracks capable of a top speed of 280kph, and for the first time boasting enough battery capacity to complete an entire race.
He said: "For some years now, I've been clear about my interest in this innovative, forward-looking discipline that's developing exponentially. I especially like the format of race meetings, the city-centre circuits and the contact with the fans.
"I'm very happy to be joining the Venturi Formula E Team and the Formula E Championship, which has become a magnificent competition in a short space of time. I can't wait to take part in testing at the end of the month."
Venturi founder and president Gildo Pastor said: "It's an honour to welcome Felipe to the Venturi family. I needed him, his experience, his speed, and his openness.
"Felipe's 15 years' experience in Formula 1 will give us a boost. With his humble nature, I know he will listen to the team and master the discipline quickly."
Venturi will host Massa in a private testing session at the end of the month where the 37-year-old will have to concentrate on getting comfortable with the feel of an electric vehicle, learning street tracks and studying a unique driving system which incorporates battery management rather than concentrating on fuel and tyres.
Massa is the latest big name to arrive, following former F1 world champion Nico Rosberg joining as an investor. The German will become the first driver to publicly demonstrate the Gen2 car at Saturday's Berlin E-Prix.
