The Cars

Five period-correct groups of legendary race cars will be featured competing in one-hour sessions, four times each over the race weekend.  Groups will include everything from the Porsche 911 to Le Mans and Formula One veterans. The first group will take the green flag Friday afternoon. 

A 3-minute pit stop during each session (driver change is optional),
will be required. When one group takes the checkered flag, the
next group is on the grid and ready to roll out behind the pace
car for their chance to race on the roads and runways of the
legendary Sebring circuit. That means continuous on-track
action. And yes, night racing will be featured on the
schedule as well.

Complementing the Classic 12 Hour will
be HSR’s signature sprint races and
endurance series.
