Pratt Miller Motorsports Captures Drivers, Teams, and Manufacturers Titles in GTD PRO

Precision, preparation, and performance defined Pratt Miller Motorsports’ 2025 IMSA WeatherTech SportsCar Championship campaign, culminating in a clean sweep of the GTD PRO Manufacturers, Drivers, and Teams Championships at the 10-hour Motul Petit Le Mans at Michelin Raceway Road Atlanta.

In a season-long display of consistency, the No. 3 Chevrolet Corvette Z06 GT3.R — operated by Pratt Miller Motorsports and driven by Antonio Garcia and Alexander Sims — secured the Drivers Championship and the Teams Championship, while Chevrolet claimed its 15th GT-class Manufacturers title overall and its first in GTD PRO.

The sister No. 4 Corvette Z06 GT3.R, piloted by Tommy Milner, Nicky Catsburg, and Nico Varrone, delivered a runner-up finish to lock in the triple crown, marking the program’s first double-podium at Petit Le Mans since 2008.

“It’s a great day for Corvette Racing, Pratt Miller, and Chevy,” said Tommy Milner, driver of the No. 4 Corvette. “The No. 3 team was perfect all year — that’s what it takes to win in this championship. It’s a whole team effort, and both crews celebrate this one together.”

Throughout the 2025 season, the Pratt Miller-led Corvette Racing operation proved the benchmark in GTD PRO competition. Between its two cars, the team earned nine podiums, including a victory at Virginia International Raceway for Garcia and Sims and multiple runner-up finishes for the No. 4 crew. Strategic execution, flawless pit work, and bulletproof reliability defined the campaign.

For Pratt Miller Motorsports, the championship adds to a legacy built on more than two decades of success at the highest level of endurance racing. The team’s 16th IMSA Teams Championship — and 13th overall sweep of Drivers, Teams, and Manufacturers titles — further reinforces its reputation as one of the most successful programs in sports car racing history.

“Their consistent performance throughout the season was a key factor in delivering these titles against the best GT competition in the world,” said Eric Warren, GM Vice President of Global Motorsports Competition. “Everyone at Chevrolet is proud of Antonio, Alexander, and Pratt Miller Motorsports for continuing to elevate the Corvette legacy.”

The victory also underscored Pratt Miller’s technical depth and collaborative synergy with General Motors, from on-track race strategy to vehicle development and engineering support.

“Winning a championship in motorsports takes dedicated teamwork and perseverance in the face of adversity,” said Jordan Dier, Motorsports Gateway Head of Business Development. “They are habits we value and we applaud Pratt Miller Motorsports for winning the Team, Driver, and Manufacturer Championships. We’re delighted to have PMM as a member of our Howell Drivers Club.”

Beyond IMSA, the Corvette Z06 GT3.R, designed and built through Pratt Miller’s engineering partnership with GM, continues to compete for titles worldwide — in GT World Challenge America, European Le Mans Series, and FIA World Endurance Championship.

For a program that has long defined excellence in motorsport, 2025 marked not just another championship — but a statement of sustained dominance and innovation.

Pratt Miller Motorsports. Champions — again.
