DAYTONA BEACH, Fla. (November 15, 2025) – Seventeen hours of available track over two days with an updated racecar is akin to opening a gift box on Christmas Day for Cadillac Racing drivers.
The IMSA WeatherTech SportsCar Championship-sanctioned test this weekend at Daytona International Speedway formally opened preparations for the quickly approaching season while closing out the 2025 campaign that began 11 months earlier at the same venue.
Cadillac Racing’s three-car Grand Touring Prototype (GTP) lineup featured a 10-driver roster that included Cadillac Formula 1Ⓡ Team test driver Colton Herta and 2025 NASCAR Xfinity Series rookie of the year Connor Zilisch, who will contest the full 2026 NASCAR Cup Series in the No. 88 Chevrolet Camaro ZL1 with Trackhouse Racing.
Data acquisition trumped lap times as the primary objective as the Nos. 10 and 40 Cadillac Wayne Taylor Racing V-Series.R and No. 31 Whelen Cadillac V-Series.R ran through prescribed plans of collecting initial feedback from 2026 aerodynamic updates and turning laps on Michelin’s new Pilot Sport Endurance tire without incident or mechanical issue.
The three GTP entries totaled 967 laps in five day/night sessions on the 3.56-mile, 12-turn road course that incorporates sections of the high-banked oval.
Cadillac joined other manufacturers in aligning timing of EVO use with the updated 2026 aerodynamic homologation.
While the V-Series.R retains signature V-Series production design elements, notable changes include removal of front dive planes and winglets and reshaping the rear wing profile.
“The initial thoughts are good. It still feels like a Cadillac, which is good because we had a good car this year,” said Frederik Vesti, Action Express Racing endurance driver in the No. 31 Whelen Cadillac V-Series.R. “The focus is getting drivers into the rhythm again at this track and fine-tuning the setup ahead of the Rolex 24.”
Highlights of the past season and a look ahead to the upcoming nine-race GTP calendar that kicks off January 24-25 with the 64th Rolex 24 At Daytona:

“Looking back on the 2025 IMSA season, I couldn’t be prouder of what our Cadillac Racing teams accomplished,” Cadillac Racing program manager Keely Bosn said. “Cadillac’s multi-year partnership with Whelen. Engineering and Action Express Racing continues to be something special; a relationship built on trust, determination, and a shared drive to win. Seeing the team deliver multiple victories this season, including Cadillac’s second consecutive Petit Le Mans win, was incredibly rewarding. It’s a testament to the team’s relentless effort and belief in what Cadillac Racing stands for.
“This season also marked our first year partnering with Wayne Taylor Racing in the GTP era. Watching the team learn the Cadillac V-Series.R, find their rhythm, finish on the podium twice including at our home race in Detroit, and represent Cadillac with such pride has been inspiring.
“We were also thrilled to bring four cars to the 24 Hours of Le Mans this year. The opportunity to campaign entries from Action Express and Wayne Taylor Racing alongside their WEC teammates, Cadillac Hertz Team JOTA, was a landmark moment for Cadillac Racing. Running shoulder to shoulder with the best in the world at the event is what fuels our passion to keep improving.
“As we close the book on 2025, I’m more excited than ever for what’s ahead. We’ve learned so much this season, and our engineers have been hard at work on some exciting technical developments that will debut next season. Cadillac Racing has never been stronger, and I can’t wait for the green flag to drop at Daytona in January.”
