2015-18: Junior formula in the Americas
Fraga raced in Formula 3 Brasil for three years, all with Prop Car Racing. Fraga's first season in 2015 did not start well, retiring in its first three races under Class B. At the following race, he finished eighth overall, and third in class. Fraga would earn a total of two pole positions, four fastest laps, nine podiums, and four class wins in the season and would finish third in Class B with 117 points. In 2016, Fraga was promoted to Class A, but only raced in four races, those being the first event at the Velopark and the last event at Interlagos. He would finish eleventh in the Class A standings, with one podium and 19 points. Fraga would return to the newly renamed Academy class in 2017. Fraga won the class, finishing the season with 190 points, with seven pole positions, seven fastest laps, 13 podiums, and 10 class wins. Simultaneously with Formula 3 Brasil, Fraga also raced in NACAM Formula 4 Championship in 2017. In his only season in 2017–18, Fraga finished second overall and earned 286 points, with five pole positions, seven fastest laps, 12 podiums, and six race wins. In 2018, Fraga participated in the U.S. F2000 National Championship. He ended the season in fourth overall, with three podiums and 213 points.
In March of that year, Fraga was named as a new signing to the Red Bull Junior Team, after winning the Toyota Racing Series championship in 2020, beating out fellow Red Bull Junior Liam Lawson.[1] He was released from the programme following the 2020 season.
Fraga also participated in the 2023 Super GT Series that same year in the GT300 class, competing with Anest Iwata Racing with Arnage in the Lexus RC F GT3 alongside Yuga Furutani and Miki Koyama, the latter joining the lineup in five of the eight rounds.[13] Fraga and Furutani would score twice across the season, with two consecutive points finishes at Suzuka Circuit and Sugo, finishing 10th and 7th respectively. Koyama, who entered with the team for the Suzuka round, did not run a stint during the race and thus remained scoreless. Igor Fraga is set to return for a second season with Anest Iwata Racing with Arnage for 2024. In February 2024, Fraga was announced as a reserve driver for Nakajima Racing in the Super Formula Championship.[2]
In 2017, Fraga qualified for the first Formula One Esports Series final, having finished 4th and 2nd in his Heat group. His results in the final however weren't as good, finishing the three races 14th, 18th and scored six points in the last race where he finished 15th. He ended the final 18th out of 20 drivers.
Fraga has participated in the FIA-Certified Gran Turismo Championships, and made his first appearance in the series in the inaugural 2018 season, participating in the Nations Cup. On the build-up to the World Final, Igor Fraga won the Americas regional final event in Las Vegas, finishing first overall with 43 points in three races and securing a World Final spot. Fraga would take the inaugural Nations Cup championship in the World Final in Monaco with 54 points.[14] Fraga returned to the series in 2019 for both Nations Cup and Manufacturer Series championships. A first corner spin in Red Bull Ring at the first semi-final of the World Final sent Fraga to last place and he would later be eliminated in the Nations Cup as a result, finishing 10th.[15] He later won that year's Manufacturer Series championship for Toyota with teammates Rayan Derrouiche and Tomoaki Yamanaka. Fraga returned for the rebooted 2020 season in both competitive series. He did not qualify for the World Finals for the Nations Cup, but did finish 4th overall in the World Finals for the Manufacturer Series alongside Shohei Sugimori and Valerio Gallo.[16]
Fraga competed in the inaugural McLaren Shadow Project in 2018 and won the series, beating runners-up Nuno Pinto and Miguel Ballester in the grand final.[17][18]
In 2021, Fraga would compete in the inaugural Olympic Virtual Series, participating in the 'Motor Sport' event in the Gran Turismo Sport game.[19][20] Fraga scored a 2nd-place finish in the first race, but would not be able to complete the following two races due to a network problem, which he later clarified on his Twitter.[21] In 2022, Fraga won the Toyota GRGT Cup championship in the Gran Turismo World Series.[3] Fraga was also appointed as the esports ambassador for the Super Formula Championship later that year.[4]
