the fastest qualifier. 1963: Johnny Rutherford (165.183 mph) was the fastest qualifier. 1964: On April 4, 1959, Dick Rathmann set the one-lap Daytona International Speedway track qualifying record driving in a USAC Champ Car race at 173.210 mph. The Champ Cars would not return to the track. The one-lap record held until 1964 when Paul Goldsmith finally broke it in a NASCAR stock car with a speed of 174.910 mph. 1969: David Pearson (190.029 mph) was the fastest qualifier. 1976: A. J. Foyt (185.943 mph) was the fastest qualifier. 1980: A. J. Foyt (195.020 mph) was the fastest qualifier again. 1983: On his first of two qualifying laps, Cale Yarborough ran a lap of 200.503 mph, a new track record, and the first 200 mph lap (320 km/h) in Daytona history. On the second lap, however, gusty winds caused him to spin, flip over, and crash in turn 4. The car had to be withdrawn, and the lap did not count. Yarborough started a backup car on race day, and was moved to the rear of the field. Ricky Rudd was credited with the fastest qualifying speed at 198.864 mph. 1990: Pole winner Ken Schrader crashed during the Gatorade Twin 125's, and was required to start a back-up car on race day. His car was moved to the rear of the field, and duel winner Geoff Bodine moved up to the pole position. 2003: Starting with the 2002 Subway 400 at Rockingham (the race after the 2002 Daytona 500), teams were not permitted to change engines during the race week. For the Daytona 500, a team must race their qualifying race with the same engine they used to qualify. An engine change between first qualifying practice and the qualifying race means the team must start in the back for that race only. After the qualifying races, teams will be allowed one engine change before the start of the final Daytona 500 practices on the Saturday before the race. The engine in the car for the Saturday practices before the Daytona 500 is the declared engine, with any engine change after the first Daytona 500 practice that occurs after the qualifying race will be penalized with the team being sent to the rear of the field. As is the case for a backup car after a crash, the respective column of cars moves up when the offending car is moved to
