IROC Holdings, owner of the IROC branding, and General Motors recently announced that Chevrolet is now the presenting sponsor of IROC.

This renewed relationship builds on a storied history between the two brands that has seen Chevrolet involved throughout IROC's history. 

"We are thrilled to welcome Chevrolet as our presenting sponsor for IROC," said Ray Evernham, co-principal of IROC Holdings. "Chevrolet has not only played a key role in my own personal career, but they've been a vital part of IROC's history, too. Rob [Kauffman, co-principal] and I have had a lot of fun bringing the IROC brand back to life, and to now have our friends at Chevrolet and General Motors involved makes it even more exciting." 

"Chevrolet is proud of our long and rich history with IROC, which dates back more than half a century, and honored to be the presenting sponsor," said Todd Christensen, director of Chevrolet Motorsports marketing. "We look forward to seeing the stars and cars back on track in a revitalized IROC."

The partnership debuted at the Rolex Monterey Motorsports Reunion, August 13-16, where IROC Presented by Chevrolet was a featured run group at WeatherTech Raceway Laguna Seca. In total, 27 authentic IROC race cars participated in the Rolex Monterey Motorsports Reunion's IROC Unser Family Cup class, with many being original Chevrolet Camaros that were campaigned in IROC competition between 1974-1989. Several drivers--including Mark Martin, Jeff Gordon, Kurt Busch, Bobby Labonte, Scott Pruett, Danny Sullivan and Ken Schrader--reunited with the original machines they raced during IROC competition.

The history between General Motors and IROC dates back to 1974 when 12 identically-prepared Chevrolet Camaros took to the track with motorsports legends like Richard Petty, A.J. Foyt, Emerson Fittipaldi and Graham Hill behind the wheel. While Chevrolet's Camaro was the designated car for the IROC Series from 1974 until 1989, General Motors returned to IROC once again in 1996 with the Pontiac Firebird, which would be utilized through the final year of series competition in 2006.
