Kamui Kobayashi, who has lost his race seat at Sauber, will continue his career in Le Mans-style GT sports car racing in 2013.
Last month, the popular Japanese tested for the closely Ferrari-linked AF Corse sports car team.
He has now inked a deal to contest this year's World Endurance Championship at the wheel of a Ferrari 458.
"It's an honour for me to become part of the Ferrari family," said Kobayashi.
