SEPTEMBER 24, 2025



Cadillac claimed its first victory of the IMSA WeatherTech SportsCar Championship season Sunday, with Jack Aitken surviving a late frantic restart to win the TireRack.com Battle On The Bricks at Indianapolis Motor Speedway. Aitken, driving the pole-sitting No. 31 Cadillac Whelen Cadillac V-Series.R in the Grand Touring Prototype (GTP) class, held off Ricky Taylor in the No. 10 Wayne Taylor Racing Cadillac V-Series.R by 0.988 of a second at the conclusion of the six-hour race on the historic speedway’s 2.439-mile road course. With the win, Cadillac became the 17th of IMSA's 18 automotive manufacturers to win a race in an IMSA-sanctioned series in 2025.
A full-course caution for a collision of Le Mans Prototype 2 (LMP2) cars with nine minutes left bunched the field for a two-lap dash to the checkered flag. Aitken, who shared the No. 31 with co-drivers Earl Bamber and Frederik Vesti, got the jump on Taylor when the green flag waved and was never headed in delivering the first win of the season for his team and manufacturer. It was the 30th IMSA class win for Action Express Racing, which fields the No. 31 Cadillac. Bamber collected his ninth series win, Aitken his second and Vesti his first.
Taylor and co-driver Filipe Albuquerque equaled their best result of 2025 with the second-place finish in the No. 10 WTR Cadillac (also second on the streets of Detroit). Tom Blomqvist and Colin Braun finished third in the No. 60 Acura Meyer Shank Racing w/Curb Agajanian Acura ARX-06.
Other class winners in the race were: Steven Thomas, Mikkel Jensen and Hunter McElrea in LMP2, driving the No. 11 TDS Racing ORECA LMP2 07 (the third straight Indianapolis win for Thomas, Jensen and TDS and second for McElrea); Mike Rockenfeller and Sebastian Priaulx driving the No. 64 Ford Multimatic Motorsports Ford Mustang GT3 in Grand Touring Daytona Pro (GTD PRO); and Brendan Iribe, Frederik Schandorff and Ollie Millroy driving the No. 70 Inception Racing Ferrari 296 GT3 in Grand Touring Daytona (GTD). The Inception crew won its first WeatherTech Championship race. Watch the Race Highlights here. (Thank you to Mark Robinson/IMSA Wire Service)

Chris Dyson put on a masterclass performance at VIRginia International Raceway, charging from last to first in the Trans Am Series presented by Pirelli TA/GT feature. After a four-tire change following qualifying forced him to start at the back of the field, Dyson methodically carved through the competition to claim his 29th-career TA class victory. The triumph also tied him with Trans Am Hall of Famer Mark Donohue for the second-most wins in TA history. (Thank you to Trans-Am Media)

Editor-in-Chief's Note: INDYCAR has released its 2026 schedule. No really big surprises here, although thankfully, Iowa was dropped after an embarrassing turnout this season. -PMD


Editor's Note: This is our dearly departed billboard, which we had at Road America for several years. Peter gifted the phrase "America's National Park of Speed" to the track, which now uses it proudly in all of its communications. -WG
