Garage 56 testing at Sebring International Raceway

Garage 56 team members pose for a group photo at the end of testing for the 24 Hours of Le Mans entry. The project's collaborators stood side-by-side on the pit road at Sebring International Raceway with NASCAR chairman and CEO Jim France alongside Hendrick Motorsports team owner Rick Hendrick. The cars will ship to Le Mans next month in preparation for the June 10-11 endurance race.

The Garage 56 entries had new decals affixed for the two days of testing. The car will bear No. 24 for the race, and the designation "IC" stands for the class of "Innovative Car."

Other decals besides the IC label adorned the Garage 56 car's hood. The FIA and ACO governing bodies are represented. The "E" decal points to the fire extinguisher release, and the "N" sticker indicates a neutral setting that releases the car in the event it needs towing.
