Bustamante, new development driver for CUPRA KIRO

The 19-year-old Filipino talent was officially announced as part of the team’s roster in June, ahead of the Jakarta E-Prix, and will now make her first on-track appearance with the outfit during the Berlin test.
Bustamante’s single-seater career began in 2022, and her rapid progress since then has been closely followed. She has raced in W Series, F1 Academy, and most recently in the GB3 Championship.

“On behalf of the team, I’m delighted to welcome Bianca to CUPRA KIRO,” said Russell O’Hagan, Chief Operating Officer at CUPRA KIRO. “Since stepping up to single seater racing only three years ago, Bianca has not only proven that she is a force to be reckoned with but has become one of the leading voices in promoting female participation in motorsport by widening the industry’s talent pipeline.
Emphasising CUPRA KIRO’s commitment to driver development, O’Hagan expressed the importance of such initiatives in shaping the future of motorsport.
“Opening and fostering opportunities for next generation racing drivers is integral to the future of our sport, and while we’re looking forward to seeing Bianca’s contribution to CUPRA KIRO, we’re equally excited to support her own development as an athlete. I can’t wait to see her embed herself in the team over the coming weeks ahead of her Rookie Test outing in Berlin.”

In the very short time that we’ve been working together, it’s been incredible to experience the team’s disruptive approach to racing in action and to see the team’s hunger and desire for success first-hand. Working with Dan, David, and the team is an invaluable opportunity for me at this stage of my career, and I’m looking forward to applying everything I learn into the GB3 Championship in 2025. I’m excited to absorb everything on-site in Jakarta and of course, to drive the team’s current Season 11 car in Berlin this July.”
