Just as the No. 93 Acura ARX-06, driven by Renger van der Zande and Nick Yelloly, crossed the finish line in first place at last Saturday’s Acura Long Beach Grand Prix, speculation about Acura’s exit from IMSA intensified. Those rumors have now been confirmed.

On Wednesday afternoon, Acura announced it will “pause” its IMSA GTP program at the end of the current season. The company did not provide a reason for the decision or specify whether the program would resume in the future.

“We are extremely proud of what we’ve accomplished during this era of Acura prototype racing, which began in 2018 with the introduction of the Acura ARX-05,” said David Salters, President of Honda Racing Corporation USA. “We are committed to competing for the championship in IMSA’s GTP category through 2026 with the hybrid Acura ARX-06.”

“We’ve scored 25 wins, 34 poles, and 10 championships during this time and look forward to finishing 2026 strong. I want to recognize all the talented women and men of HRC US, Acura, Meyer Shank Racing, and Oreca who have worked tirelessly to get us to where we are in this highly competitive GTP field.” — David Salters

While Acura will step back from IMSA’s GTP class, it will expand its involvement in IndyCar. Starting in 2026, the automaker will adorn Meyer Shank Racing’s Honda-powered Indy cars, including Marcus Armstrong’s No. 66 entry at next month’s 110th running of the Indianapolis 500. The announcement did not detail plans for 2027 but mentioned exploring “other high-profile opportunities in IndyCar during the 2026 season and beyond.”

IndyCar Shift Leaves IMSA Fans Questioning the Future

Though IndyCar remains a competitive and exciting series, the move away from IMSA’s GTP class—where Acura had a factory-level effort—disappoints many fans. While customer teams may continue using existing hardware, the absence of a factory-backed program marks a significant shift.

Industry rumors suggest Porsche may also conclude its IMSA GTP effort with Penske at the end of the year, mirroring its recent announcement regarding its WEC program.
