Sunday 6th February 1972

Reliability concerns for the 3 liter cars led to the Daytona 24 Hours being replaced by a 6 hour event. Ferrari took the win with the 512P of Mario Andretti/Jacky Ickx gaining the lead when Ferrari teammate Tim Schenken had a tire puncture with 15 minutes left. Schenken and co-driver Ronnie Peterson still finished second despite the puncture and late gearbox problems. The Jo Bonnier entered Lola challenged early before retiring, while the lone Alfa-Romeo threat ended when the Peter Revson/Rolf Stommelen car blew late.
