The 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 – not decals – a larger fuel cell, carbon brake discs and specially designed Goodyear Eagle race tires.

Track testing for the Camaro 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 endurance race. Altogether the test car and its previous iteration have logged more than 3600 miles at six separate tests (Road Atlanta, Virginia International Raceway, Goodyear Proving Grounds, Carolina Motorsports Park, Sebring International Raceway and Daytona International Speedway).
