DAYTONA, Fla.—Sebastien Bourdais in the #5 Action Express Coyote-Corvette was quickest in the night practice session at the 2015 Tudor United SportsCar Championship Roar before the Rolex 24, but nobody cared much—probably not even Bourdais himself.
Night practice is more about new drivers familiarizing themselves with the track at night, drivers familiarizing themselves with new car at night, and crews making sure the important parts function in the dark—making sure turning n the headlights doesn’t turn off the running lights or shot out the whole wiring loom, for instance.
