Gianluca de Castro Petecof (born 14 November 2002) is a Brazilian racing driver. He currently competes full-time in the Brazilian Stock Car Pro Series, driving the No. 101 Mitsubishi Eclipse Cross for KTF Sports. He was champion of the Formula Regional European Championship in 2020, and has competed in the FIA Formula 2 Championship with Campos Racing.
Petecof is a former member of the Ferrari Driver Academy.
In 2018, Petecof made his single-seater racing debut in the Italian and ADAC Formula 4 Championships. The former would be more successful for Petecof, with one win and four further podiums helping him to fifth in the standings, meanwhile the Brazilian only scored one podium in ADAC F4 on his way to tenth.
The next year, Petecof continued racing in both Italy and Germany. He won four races and became vice-champion in the Italian series, 136 points behind Dennis Hauger. In ADAC F4 Petecof achieved one victory and finished fifth.
In 2020, Prema Powerteam announced that Petecof would drive for them in the Formula Regional European Championship alongside Jamie Chadwick, Oliver Rasmussen and fellow Ferrari Academy member Arthur Leclerc. Petecof started the season strongly, amassing four victories in the first three rounds. Despite his strong start to the season, Leclerc was able to keep the championship battle going until the last race of the season at Vallelunga, where Petecof was crowned both rookies' and series champion.
It was announced in early February that Petecof would join Campos for the 2021 FIA F2 Championship. He lined up alongside Ralph Boschung. In June, he left the team, citing financial reasons.
In December 2017, Ferrari added Petecof to their Driver Academy. In January 2021, Petecof announced he had left the academy.
In 2022, Petecof raced in the Stock Car Brasil with Full Time Sports. He would partner ex-Formula 1 race winner Rubens Barrichello.
