Following the intense Daytona Duel races, NASCAR Cup Series drivers returned to Daytona International Speedway for the second practice session on Friday. Many competitors, including William Byron, have switched to backup cars after incidents during the previous day’s events. This session is critical for teams refining their setups ahead of the Daytona 500, with drivers pushing their vehicles to the limit to improve performance.
The Daytona 500 practice results from this session highlight Austin Dillon as the fastest driver, completing a lap in 46.006 seconds with an average speed of 195.626 mph, topping the field in this highly competitive environment.
Backup Cars Enter the Spotlight After Recent Crashes
William Byron’s backup car was shipped from Charlotte, North Carolina early Friday morning to replace his damaged primary vehicle. Ross Chastain, Daniel Suarez, and Chris Buescher also announced they are competing with backup cars following setbacks during the Duel races. This switch underscores the challenges drivers face as they balance speed with durability ahead of the marquee race.
Standout Performances in the Practice Session
Austin Dillon secured the fastest time among the 37 drivers who took part in the session, narrowly edging out Alex Bowman, who recorded a lap of 46.047 seconds. Justin Allgaier followed closely with a best lap of 46.137 seconds, while Chase Elliott and Ricky Stenhouse Jr. rounded out the top five with times of 46.149 and 46.160 seconds, respectively.
