1970 24 Hours of Daytona

The 1970 24 Hours of Daytona was an endurance race at the 3.8 mile road circuit at the Daytona International Speedway, Daytona Beach, Florida, USA that took place on January 31 and February 1, 1970. It was the first race of the 1970 World Sportscar Championship season. This was the first race for the iconic Porsche 917K and Ferrari 512 S cars.[1]

Race

Ex-Aston Martin race team manager John Wyer's Gulf-sponsored team finished 1-2 in the race and broke the distance record by 190 miles; with the #28 works Ferrari finishing 3rd. It was the first race in which the iconic Porsche 917K appeared, and this event effectively began the 917's domination of the WSC for the next 2 seasons.
