The 1993 DieHard 500 was the 18th stock car race of the 1993 NASCAR Winston Cup Series season and the 25th iteration of the event.

On lap 70, a five-car incident featured Active Motorsports driver Jimmy Horton flipping over the protective outside wall in turn one, meant to keep cars within the track.

While Horton wasn't seriously hurt, in the same accident, owner-driver and Birmingham, Alabama native Stanley Smith would suffer a basilar skull fracture and partial paralysis of the right side of his body after slamming his car into the turn one wall, spilling blood on most of his racing firesuit.

Bonnett, making a one-off appearance since retiring in 1990, was uninjured and would eventually decide to commentate the rest of the race for CBS.

Bill Elliott, driving for Junior Johnson & Associates, would win the pole, setting a time of 49.772 and an average speed of 192.397 miles per hour (309.633 km/h) in the first round.

Due to the two hour red flag caused by Bonnett flipping his car and damaging the fence, CBS left during the red flag to air some of their same day coverage of the Tour de France but returned to Talladega to live coverage of the rest of the race.
