Formula Three European champion Esteban Ocon will race in GP3 after securing a seat with the ART Grand Prix team.
The Frenchman's future had look uncertain despite beating Toro Rosso F1 driver Max Verstappen to the F3 title last year.
Ocon's drive is in part funded by Pirelli's prize of €100,000 for moving to GP3 from F3.
"I am very pleased to contest GP3 with ART Grand Prix because it's the project that I wanted to happen the most," said Ocon.
"After a great season in 2014 and given the experience and the team's track record, my ambition is to repeat this in 2015 and win the title.
"There are a few question marks because I have not yet tried out the car, but ART Grand Prix has all the skills, data and talent to allow me to have such high ambitions."
Ocon completes ART's line-up in GP3, and he will partner Alfonso Celis and Marvin Kirchhofer.
"ART Grand Prix is pleased to work with Esteban who had an exceptional season in 2014," said ART GP3 boss.
"We should not minimize the magnitude of the task at hand because Esteban is only just starting in GP3 and will have to adapt to the requirements of the discipline in the first race.
"But we trust in his talent and potential to achieve this and to join in the fight for the title."
