Jamie Chadwick experienced her first Formula 1 test with the Atlassian Williams F1 Team at Portimao, Portugal, completing 32 laps in the podium‑finishing 2025 car under TPC rules. The 28‑year‑old British driver, a Williams ambassador and Sky Sports F1 pundit, called it "the best day of my life so far" and praised the opportunity to gather data for the team’s 2026 return to Portimao. Chadwick, who won the all‑female W Series and became the first woman to win a road‑course race in Indy NXT in 2024, credited the experience to her long‑standing dream of following Susie Wolff’s footsteps.

Williams team principal James Vowles highlighted her record‑breaking career and the importance of her feedback for both her development and the team’s young drivers. The test marks the second female F1 test of the year after Doriane Pin’s 2021 Mercedes outing and is the first British female test since Jessica Hawkins in 2023.
