[15] In ADAC Formula 4, in a season which was dominated by eventual champion Lirim Zendeli, Fittipaldi's sole win came at the second Hockenheimring round.

[17] In 2019 Fittipaldi competed in the 2019 Formula Regional European Championship for the Prema Powerteam alongside Frederik Vesti and Olli Caldwell.

This included a win in just his second race, although he did not stand on the step of the rostrum due to previous winner Olli Caldwell being disqualified post-race.

[24] At the start of January 2020, Fittipaldi was announced to be driving for HWA Racelab in the 2020 FIA Formula 3 Championship, partnering Jake Hughes and Red Bull junior Jack Doohan.

[33] In May 2021, it was announced that Fittipaldi would switch to Charouz Racing System in the 2021 FIA Formula 3 Championship, partnering Reshad de Gerus and Logan Sargeant.

[37] At the Red Bull Ring, Fittipaldi finished 11th on the road, but numerous penalties promoted to fourth, scoring his first points of the year.

[48] Fittipaldi replaced David Beckmann, who was forced to vacate his seat due to financial difficulties, in the Charouz line-up.

[49] A few days before his debut weekend Fittipaldi stated that he "wasn't really expecting" his F2 call-up before it happened, but was "looking forward to [racing at Monza]".

[50] His first round in Monza was positive, he originally finished ninth in the feature race but was demoted five seconds due to a penalty which dropped him to 11th.

[54] The following day, Fittipaldi was involved in an incident at the start of the feature race in which he hit the stalled car of Théo Pourchaire from behind.

Both drivers were extracted and given medical treatment, before Fittipaldi was transferred to the King Fahad Armed Forces Hospital via helicopter.

[55] Later that night his brother Pietro reported that he [Enzo] was awake, and that he had only sustained a fracture of his right heel as well as a cut above his left eye.

A crash for Roy Nissany followed, and in the last laps passed Logan Sargeant and Ralph Boschung for second place, and his first F2 podium.

He managed to take the final points' positions in eighth during the sprint race, courtesy of overtaking Jake Hughes on the fourth last lap.

His sprint race ended in disappointment, as he made a failed overtake on Jüri Vips for tenth, instead clouting the wall and damaging his suspension.

Worst was to come as he stalled at the start of the sprint race and retiring after colliding with Roberto Merhi, which earned a five-place grid drop.

[78] He finished tenth in the feature race and added a point, only because Richard Verschoor suffered an engine issue ahead and retired.

[80][81] In the feature race, he was up to fifth by lap 4, and made a successful overcut during the pit stops that saw him jump to second place behind Théo Pourchaire.

[94] In January 2023, Fittipaldi was confirmed to be driving for the British outfit for the 2023 Formula 2 Championship alongside fellow Red Bull junior Zane Maloney, ahead of what is to be his "biggest opportunity of [his] career.

[99] In Australia, an ill timed red flag left Fittipaldi 16th in qualifying, his weekend went from bad to worse after crashing on his way to the grid for the sprint race.

[109][110] In the sprint race he lost positions after a collision Kush Maini, and later retired after the Indian driver forced him off-track, and spun.

A first Formula 2 win eluded him once again, as he missed the pit entry and rejoined the race in ninth place, which meant that the other alternate strategy drivers Richard Verschoor and Ayumu Iwasa were able to jump him.

[113][114] In Silverstone, Fittipaldi qualified sixth once again, and soared to fourth in the sprint race, which included a tense battle with Martins.

Following a safety car restart, Fittipaldi passed teammate Maloney on the final lap for fifth, but post-race penalties for Martins and Oliver Bearman promoted him to third place, rounding out his most successful weekend up to that date.

[120][121] Fittipaldi qualified down in 19th at Zandvoort, but in the feature race he made a sterling recovery drive to take seventh place.

However, he soon encountered brake issues which led to him losing the lead to Frederik Vesti, eventually force to settle for second.

He would end the streak of poor results in the Austrian feature race, starting 15th, he pitted early and managed his tyres well to secure fourth place.

[136] A late puncture ruined his chances of points in the sprint race, but a strong showing in the feature saw Fittipaldi rack up fifth place for his efforts.

[138] Ahead of the round in Qatar, Fittipaldi parted ways with Van Amersfoort Racing and was replaced by 2024 GB3 runner-up John Bennett.

[148][149] Fittipaldi was chosen by Jaguar TCS Racing in May 2024, to participate in the Formula E Berlin rookie test alongside Sheldon van der Linde.
