The former Alfa Romeo Formula 1 reserve driver will race the British squad’s #12 Porsche 963 LMDh along with team regular Will Stevens and Norman Nato.
Ilott and Nato were announced on Monday by Jota for #12 in its expanded two-car Hypercar squad along with Phil Hanson, who will race the #38 car together with Oliver Rasmussen and a yet to be determined third driver.
Twenty-five-year-old Ilott landed the Jota drive after a successful test in the team's first 963 at Qatar at the beginning of this month.
“We’re very excited to have Callum in the car for next season,” Jota team principal Sam Hignett told Autosport.
“He tested with us in Qatar and he did the excellent job we were expecting.”
Ilott added: "I’m so excited to be racing a Porsche in the top-class with Hertz Team Jot. I had a two-day test recently and the car felt great and was enjoyable to drive.
“I’ve been ultra-impressed with the team, they’re incredibly professional, and I already know that with the Porsche, we’re going to be challenging for top results next season and hopefully success at Le Mans itself."
Ilott is switching to sportscar after splitting with the Juncos Hollinger IndyCar team for which he had raced since the end of 2021.
His previous sportscar experience came with the Iron Lynx Ferrari squad in 2021, the season in which he participated in a pair of Friday F1 free practice sessions at the wheel of the Ferrari-engined Alfa Romeo C41.
