Alpine Junior Driver Abbi Pulling edged ahead of the Iron Dame Doriane Pin in the second F1 Academy practice session at the Miami International Autodrome.
Pulling pulled away from the Frenchwoman to lead the F1 Academy grid with the fastest time of 1:59.237s, as the Mercedes Junior Driver struggled with oversteer and her set-up.
After a slight delay in the schedule, the drivers set off for a 40-minute second practice session after the sole Formula 1 practice session.
Most drivers on the grid have never raced at the Miami International Autodrome, with the former W Series drivers being part of the handful to have experience racing here.
The Championship leader was the first to set out on a flying lap before McLaren Development Driver Bianca Bustamante set the initial fastest lap with 2:00.655s.
Williams Academy Driver Lia Block followed a second behind Bustamante on home soil in her first full season racing single-seater cars.
The midfield was tightly packed in the first 10 minutes of the session, with less than two seconds covering the top ten.
Slightly grazing the wall in Turn 16, Pulling abandoned her flying lap as the Iron Dame climbed from sixth to second in the first 10 minutes of the session.
Pin set the fastest time in the first practice session in Miami but expressed some concerns over set-up, locking up ahead of the first DRS zone.
The Mercedes Junior Driver momentarily fell to eight, until she set the fastest lap with 2:00.358s.
Pulling snatched the fastest time from the Frenchwoman 15 minutes into the session, gaining four-tenths on Pin before heading to the pits after cutting the kerb.
Bustamante firmly remained in the top three in the first half of the session, battling with the Alpine and Mercedes Juniors for the top spot.
The Wildcard Entrant Courtney Crone continued to struggle after a slow morning session, finishing approximately six and a half tenths behind the full-time drivers.
Crone has experienced great success in racing sportscars, but her F1 Academy appearance marks her first single-seater experience in four years.
Pulling led the grid in the second half of the practice session with Pin tailing closely behind as Nerea Martí took Bustamante’s spot as third-fastest.
As half of the grid filled the pits, the young rally star Block pursued a flying lap aiming to finish in the top ten on home soil.
Ferrari Academy Driver Maya Weug pushed to improve on her fourth-placed spot from the first practice session but sat just one-tenth behind the fastest driver on the grid.
Pulling improved her fastest time with 15 minutes to spare, setting a 2:00.129s, as the rest of the grid re-appeared on track after a pit break.
The Alpine Junior Driver scored purple sectors across the board, breaking the two-minute mark.
Pin tailed closely behind Pulling, but faced pressure from the speedy Spanish driver sporting the Tommy Hilfiger livery.
The Al Qubaisi sisters, despite having experience in F1 Academy, struggled to make a mark in the top 10.
On a promising flying lap, the McLaren Junior Driver locked up twice towards Turn 17 and fell to sixth-fastest.
The Iron Dame subtly improved her time but ran wide in the middle sector as the Spanish driver Martí snatched second-fastest in front of her sponsor Tommy Hilfiger.
Martí greatly improved her speed in the final seven minutes of the session, clocking a 1:59.634s.
Haas-nominated driver Chloe Chambers climbed her way up to third-fastest on home soil, sitting in front of the Ferrari Academy Driver on her first visit to America.
In the final five minutes of the session, 14 drivers were all within a second of each other as the all-female grid fought for the fastest spot.
Pulling slightly edged ahead of her fellow drivers, despite claiming she felt unwell earlier today, pulling ahead of the American driver in second.
Heading into the pits in the final moments, Chambers abandoned her flying lap while also having her 14th lap deleted for exceeding track limits at Turn 5.
After creating a gap to the rest of the grid, Pulling returned to the pits with a final time of 1:59.237s.
The Tommy Hilfiger driver sat just three-tenths behind Pulling before the Frenchwoman took the second-fastest slot even with an error.
The Iron Dame struggled with oversteer in the middle sector of her final lap, solidifying her set-up concerns from earlier today.
On home soil, Chambers put her Haas-nominated Campos Racing car in fourth-fastest, ahead of Brazilian racer Aurelia Nobels in fifth.
Despite a strong first half of the session, Bustamante fell to seventh behind Weug in sixth.
Returning F1 Academy driver Amna Al Qubaisi took the eight-fastest spot ahead of Emely De Heus as the Red Bull trio rounded out the top ten.
The drivers look ahead to Race 1 tomorrow, with concerns rising around track limits as many drivers struggled with the tight middle sector.
On the hunt for her first official win of the season, Pulling will aim to extend her lead at the top of the leaderboard in both races this weekend.
