They started lining up the champagne glasses inside the Hendrick Motorsports garage with 30 minutes remaining in the 24 Hours of Le Mans.

The No. 24 Chevrolet Camaro wasn’t going to win the most prestigious endurance race in the world — the specialized “Garage 56” entry wasn’t eligible for any class victories — but simply completing a full 24 hours was good enough to declare NASCAR’s massive effort to return to Le Mans for the first time since 1976 a smashing success.

“How’s it feel to take the checkered flag at Le Mans?” team owner Rick Hendrick radioed seven-time NASCAR champion Jimmie Johnson as he completed the 285th lap for the Camaro around the Circuit de la Sarthe.

“Awesome,” Johnson replied.

Anticipation had built all week for the car dubbed “Le Monster,” in part because it was so different than the rest in the 62-car field, its V8 engine had a distinct rumble that drowned out the competition, and because few had any expectations for the NASCAR entry.

Jim France, owner of both NASCAR and IMSA, had brokered this deal to get NASCAR’s second-year Next Gen stock car into the race as part of Le Mans’ “Innovative Car” class that showcases technology. He then recruited Rick Hendrick, Chevrolet and Goodyear — the winningest team, manufacturer and tire in NASCAR’s 75-year history — to collaborate on the project.
