Dodge Daytona sets 28 speed records at Bonneville Salt Flats

Summary

In September 1971, a Dodge Daytona, banned from NASCAR, ran at the Bonneville Salt Flats, achieving 28 speed records. The car, driven by Bobby Isaac and managed by crew chief Harry Hyde, reached a notable flying mile speed of approximately 216.9 mph. The NASCAR rules capping displacement for aero-bodied cars led to the Daytona's exclusion from the series, prompting the team to seek record-setting opportunities elsewhere. This event is remembered as a significant moment in motorsport history, emphasizing the car's performance despite lack of competition.
