Fittipaldi finished eighth in the championship taking six podiums, Maloney is stepping up to FIA F2 after finishing second in Formula 3 for Trident.
The Brazilian driver is delighted to be racing for Carlin and is eagerly anticipating the first round of the season in Bahrain.
Fittipaldi said: “I’m extremely excited to be joining Carlin and as well to be part of the Red Bull family for the 2023 season.
“It’s an amazing opportunity and I can’t wait for the first race weekend in Bahrain.”
Maloney took three wins last season including the Feature Race in the pulsating finale at Monza but just missed out on the title.
The 19-year-old said: “Joining Carlin in F2 and to do so as part of the Red Bull Junior Team is a fantastic opportunity after my first year of F3 last season.
“I’m re-joining a team I know extremely well and have won a championship with before in F4.
“I’ve seen first-hand how strong the team are in F2 and we had a great test together last year in Abu Dhabi.
“To embark on this journey in Red Bull colours is a dream come true and I’m incredibly excited to get the season underway in Bahrain next month.”
Team Principal Trevor Carlin is very happy with his lineup of drivers in FIA F2.
Carlin said: “As a Team boss, Enzo and Zane are a dream pairing with both experience and potential.
“Enzo was a driver who really caught our attention last year and will be looking to build on the strong results he had in his rookie season.
“Zane was incredibly impressive in his rookie season of F3 and it’s fantastic to welcome him back to Carlin.
“He certainly needs to focus on building his experience in the first half of the season but I think by the mid-way point we’ll start to see some real flashes of potential.”
The 14-round FIA F2 season will begin on the 3-5 of March in Bahrain.
