Cadillac Racing swept all three GTP titles available in the 2026 IMSA WeatherTech SportsCar Championship, and today the program spelled out the technical and organizational work that made it happen. The No. 31 Cadillac Whelen entry won the Team Championship and delivered the Driver title to Jack Aitken. Cadillac itself took the Manufacturer Championship, its fifth IMSA Manufacturer title since 2017.
The engineering foundation was a new aero and braking package introduced on the V-Series.R at the start of the season. Program Manager Keely Bosn described the objective plainly: make the car more drivable, not just faster. The package proved itself immediately. “At Daytona, we hit the ground running,” Bosn said. “The drivers all spoke very positively about the changes we’ve made.” The No. 31 went on to win both Detroit, Cadillac’s home race, and Watkins Glen. Wayne Taylor Racing scored a breakthrough of its own, the No. 10 taking the team’s first V-Series.R victory at Road America. Across nine races, Cadillac GTP entries collected 11 podiums, a streak traceable to last year’s Indianapolis round.
The organizational story is as important as the aero update. Cadillac began its “One Team” strategy in 2025, coordinating Action Express Racing and Wayne Taylor Racing in IMSA with Hertz Team JOTA in the World Endurance Championship. Engineers and race leads from all three programs attended races in both series this year, sharing setup data and methodology across teams that might otherwise operate in separate silos. The driver roster reinforced it. Jack Aitken and Earl Bamber raced across most of both the IMSA and WEC calendars, with Jordan Taylor, Will Stevens, Louis Delétraz, Filipe Albuquerque, and Ricky Taylor all making appearances in both series.
“It’s one thing for us on the technical side to be pushing certain methodologies or setups,” Bosn said. “It’s another thing for that to come from the drivers. The willingness from each team to listen to our drivers and to take those learnings themselves has been phenomenal.”
The season-wide statistical picture is consistent with a disciplined points campaign rather than a dominant one. The No. 31 carried two wins and seven podiums from eight starts into the Petit Le Mans finale, where Cadillac clinched all three titles without winning the race. The championship margin in the Manufacturer standings was 136 points over Porsche. The No. 31 collected additional season-wide awards for laps led, pole positions, sustainability, and pitlane efficiency, the last of which is a metric that reflects the program’s organizational tightening as much as its raw pace. Cadillac Racing also won the 2026 DHL Sustainable Endurance Award at Le Mans for its WEC operations earlier this season, so the sustainability recognition is now doubled across both programs.
The titles land in a broader GM motorsports year. Chevrolet separately clinched its 16th GT-class IMSA Manufacturer title at Petit Le Mans, the second consecutive GTD PRO championship for the Corvette Z06 GT3.R.
For Cadillac Racing, the calendar has not slowed. Two WEC rounds remain before the end of 2026, and Bosn noted that preparation for the 2027 IMSA season, which opens at Daytona in roughly three months, is already underway. Winning three championships in the same year tends to raise the target for the next one. Cadillac spent 2025 building the organizational infrastructure to get here; the question now is whether the One Team approach can sustain this standard rather than just establish it.
