Cadillac Racing sweeps three IMSA titles in 2026 season

Cadillac Racing captured three 2026 IMSA WeatherTech titles — Manufacturer, No. 31 team, and driver Jack Aitken — after engineering upgrades and a coordinated ‘One Team’ approach across its programs.

Cadillac Racing secured three championship crowns in the 2026 IMSA WeatherTech SportsCar Championship: the GTP Manufacturer title, the No. 31 Cadillac Whelen Team Championship, and driver honors for Jack Aitken. GM attributes the results to aerodynamic and braking updates deployed on the V-Series.R for 2026 and to a consolidated ‘One Team’ strategy that united Action Express, Wayne Taylor Racing and Hertz Team JOTA.

The No. 31 entry provided pivotal wins at Detroit — identified by GM as Cadillac’s home race — and at Watkins Glen, delivering key points toward the team championship. Wayne Taylor Racing’s No. 10 also contributed strong results, including a V-Series.R victory at Road America, underscoring depth across Cadillac’s factory-supported efforts.

For Michigan enthusiasts, the Manufacturer title and the Detroit win reinforce Cadillac’s performance pedigree at home and signal the impact of technical updates developed for the V-Series.R platform. Next, Cadillac Racing will likely build on the integrated team model and the 2026 development package as it plans future IMSA campaigns and any street- or track-focused performance models tied to racing lessons.
