rookie test at Marrakesh's Circuit International Automobile Moulay El Hassan on 13 January 2019. FIA Formula 2 and progression into top-level racing (2019–present) Calderón returned to Arden for the 2019 FIA Formula 2 Championship and became the first woman to drive in the series. The renamed Alfa Romeo Racing team retained her as its test driver for the year. She stated that her two Formula One test sessions assisted her acclimatisation to Formula 2. At the Baku feature race, Calderón became the first woman in history to lead a lap in Formula 2. Poor qualifying results from a lack of tyre preparation led her to employ different strategies to gain position in a feature race. She had two race engineers during the season. Calderón had a best finish of 11th at Circuit Paul Ricard and was 22nd in the drivers' standings with no points scored. Late in the year, she obtained sponsorship that allowed her to enter the season-ending Autódromo Hermanos Rodríguez double header round of the Porsche Supercup in Team Project 1's No. 24 911 GT3 Cup car, retiring from the first race and finishing 25th and last in the second. Following the purchase of Arden's Formula 2 entry for the 2020 season by HWA Racelab and the signing of drivers Giuliano Alesi and Artem Markelov, Calderón left the team and sought a career in either American or endurance racing. As a result she left Formula 2 to join the Super Formula Championship with Drago Corse with ThreeBond for the 2020 season. Team owner Ryo Michigami negotiated with her late in December 2019 and concluded with an agreement not long after. Michigami selected Calderón over Nobuharu Matsushita for the seat and she spoke to him regularly about the SF19 car. In addition to her Super Formula seat she remained at Alfa Romeo's Formula One team as a test driver. Calderón worked with the reserve driver Robert Kubica to develop its C39 car, and was appointed an ambassador for the team. She also entered three rounds of the 2019–20 F3 Asian Championship with Seven GP, taking six top-ten finishes for 31 points and 13th in the drivers' standings. She entered the 2020 24 Hours of Daytona (part of the IMSA SportsCar Championship) alongside Rahel Frey, Katherine Legge and Christina Nielsen in the No. 19 GEAR Racing Lamborghini Huracán GT3 Evo. Calderón prepared for the race by increasing her fitness regime
