NASCAR unveils Garage 56 car, full details and specs

DAYTONA BEACH, Fla. – NASCAR officially unveiled the Next Gen Chevrolet Camaro ZL1 and livery it plans to race as the Garage 56 entry in the 2023 24 Hours of Le Mans. The Garage 56 project, which is anticipated to be approved for entry by l'Automobile Club de l'Ouest (ACO) in the coming weeks, is a partnership between NASCAR, Hendrick Motorsports, Chevrolet and Goodyear – the winningest team, manufacturer and tire in the sport's 75-year history.PHOTOS: See the car and livery for Garage 56

The systems and components of the Chevrolet Camaro ZL1 are largely unchanged from the Next Gen race car that competes weekly in the NASCAR Cup Series. Among the changes made to prepare the car for an endurance race are functioning headlights and taillights, a larger fuel cell, carbon brake discs and specially designed Goodyear Eagle race tires.

"From the beginning of this project, it was important to us that the car we bring to Le Mans is a true NASCAR stock car," said Jim France, NASCAR Chairman and CEO. "While there have been some adjustments to allow the car to compete in a 24-hour endurance race, fans in Le Mans will be treated to the full NASCAR experience."RELATED: Daytona test serves as key marker | Star-studded lineup revealed for Garage 56

On-track testing for the project began last August at Road Atlanta with two-time 24 Hours of Le Mans winner Mike Rockenfeller, who will be joined by seven-time NASCAR Cup Series champion Jimmie Johnson and 2009 F1 world champion Jenson Button behind the wheel at the upcoming 100th anniversary of the world-famous endurance race. Altogether the test car and its previous iteration have logged more than 3,600 miles at six separate tests (Road Atlanta, Virginia International Raceway, Goodyear Proving Grounds, Carolina Motorsports Park, Sebring International Raceway and Daytona International Speedway).
