Tony Stewart won a chaotic Nationwide Series race at Daytona International Speedway that ended with a frightening last-lap crash.

Regan Smith was leading coming to the checkered flag when he was turned sideways into the wall. Cars began wrecking all over the track, and rookie Kyle Larson's car went sailing into the fence that separates the track from the grandstands.

Stewart slid through the wreckage to the win.

When Larson's car came to a stop, it was missing its entire front end. There was a gaping hole in the fence, and a burning piece of car inside the fencing.

Shortly before the final three-lap sprint to the finish, Michael Annett was taken to a local hospital for further evaluation after a 13-car accident with five laps remaining.
