Chevrolet has won the IMSA GTD Pro Manufacturer Championship in back-to-back seasons, securing the title Saturday when the checkered flag fell on the 10-hour Petit Le Mans at Michelin Raceway Road Atlanta.
The championship-clinching car was the No. 74 DragonSpeed Chevrolet Corvette Z06 GT3.R, driven by Giacomo Altoé, Casper Stevenson, and Sebastien Bourdais, which finished sixth in class. Corvette Racing by Pratt Miller Motorsports contributed two more entries, finishing eighth and 12th in GTD Pro to bolster the manufacturer points total.
The result gives Chevrolet its 16th GT-class manufacturer championship since Corvette Racing entered competition in 1999, and its sixth GTD Pro or GT Le Mans manufacturer title since 2014, more than any other automaker in IMSA. It is also the fourth manufacturer championship won with the eighth-generation mid-engine Corvette, a platform that arrived as a racing proposition alongside the road car and has been accumulating hardware at a consistent pace since.
Bourdais, notably, is no stranger to high-stakes endurance partnerships. He ran the WEC season opener for Cadillac Hertz Team JOTA in 2026 before cycling into this Corvette program, a reminder of how thin the top tier of GT and endurance driving talent is spread across competing manufacturer programs.
The 2025 GTD Pro title, which started this back-to-back run, was Chevrolet’s 40th IMSA championship and eighth since the modern era began in 2014. Repeating it in 2026 against a field that IMSA and GM both describe as the strongest collection of production-based GT manufacturers in the world adds weight to what could otherwise read as a routine defense. Corvette’s Corvette Z06 GT3.R is the racing derivative of a car that sold 24,533 units in the United States in 2025, down from 33,330 in 2024, so the manufacturer championship carries commercial resonance beyond the trophy.
GM President Mark Reuss framed the result in those terms, connecting the racing program to the retail product: the championship, in his words, “strengthens the connection between Corvette Racing and the Corvettes our customers drive every day.” It is the standard posture for a factory racing program, but in this case the underlying point is legitimate. GTD Pro runs production-based machinery with strict homologation rules, so the Z06 GT3.R is genuinely close to what sits in a showroom, mechanically speaking.
Chevrolet’s bid for a third consecutive title begins at the Rolex 24 At Daytona on January 30–31, 2027. Two straight is a streak. Three would be something harder to explain away as circumstance.
