Jack Aitken, Earl Bamber, and Frederik Vesti steered the No. 31 Action Express Cadillac to a hard-fought victory at the 2025 IMSA Indy Battle On The Bricks, securing Cadillac’s first win of the season.
The race was contested on the iconic 2.439-mile IMS road course, featuring a highly competitive field of 12 GTP class cars, 12 LMP2 entries, 12 GTD PRO cars, and 18 GTD teams, all battling through dynamic conditions on Sunday, September 21, 2025.
The race began with Jack Aitken at the wheel of the pole-sitting No. 31 Whelen Engineering Cadillac V-Series.R seizing an early lead that would later yield to a dominant run.
Aitken was challenged early on by the No. 10 Wayne Taylor Racing Cadillac driven initially by Ricky Taylor, while the No. 93 Acura MSR took a remarkable jump from fifth to second on the opening lap.
The race was punctuated by several full-course cautions, first caused by debris from contact in the GTD classes involving the No. 47 Ferrari and No. 19 Aston Martin, which led to a wing mirror being left on the main straight—posing a safety risk.
The caution led to a flurry of pitstops including the No. 31 Action Express Cadillac, relinquishing the race lead to Taylor in the No. 10 WTR Cadillac and Matt Campbell’s No. 6 Porsche Penske Motorsport 963, who opted to stay out.
Aitken was able to pass both Campbell and Taylor in succession to take the lead again, as Frederik Vesti took over and executed a masterful duel against Acura’s Kakunoshin Ohta, building a significant lead of around 10 seconds before handing the car to Earl Bamber and later Aitken for the closing stages.
However, another caution involving LMP2 contender George Kurtz in the No. 04 CrowdStrike by APR Oreca 07 Gibson triggered a full-course yellow with just nine minutes left, setting up a dramatic two-lap sprint to the finish.
The race concluded with a thrilling green-white-checkered finish, where Aitken fended off an intense challenge from Taylor by a mere 0.988 seconds, securing Cadillac’s first victory in the 2025 IMSA season and Action Express Racing’s milestone 30th win in the series.
Tom Blomqvist’s No. 60 Meyer Shank Racing Acura completed the podium, as BMW M Team RLL’s No. 24 car driven by defending Indianapolis winner Philipp Eng and co-driver Dries Vanthoor finished fourth with the No. 93 MSR Acura taking fifth.
