Leonardo DiCaprio has entered a team into the Formula E Championship as part of a joint venture with Venturi Automobiles.
The Hollywood star, a staunch environmental activist, is the co-founder of the Venturi Grand Prix Formula E Team that will compete in the inaugural series in 2014.
"The future of our planet depends on our ability to embrace fuel-efficient, clean-energy vehicles," the actor said. "Venturi Grand Prix has shown tremendous foresight in their decision to create an environmentally friendly racing team, and I am happy to be a part of this effort."
The series, which is exclusively for electric cars, is the 10th and final entrant for the open-wheel Championship that is set to debut in September 2014 and continue until June 2015.
Formula E CEO Alejandro Agag said: "I want to give a very special welcome to our Championship to Leonardo DiCaprio.
"Very few environmental leaders have helped more than him to spread the message of sustainability around the world. Having people like him and Richard Branson - global ambassadors for the environment - is a privilege for our Championship and will greatly help us to spread the use of electric cars in cities around the planet."
Other teams who have entered the series are IndyCar's Andretti Autosport and Dragon Racing, former F1 team Super Aguri, Audi-backed ABT, Richard Branson's Virgin, Drayson Racing, e-Dams, China Racing and Mahindra Racing.
