In testing, the Shelby Daytona Coupe attained a top speed of 196 mph, and went on to win the GT class at the 1964 24 Hours of Le Mans. Shelby had beaten Ferrari on the biggest stage; however, the fast and reliable Ferrari 250 GTOs were again victorious in the 1964 International Championship for GT Manufacturers. The Championship was controversial: Enzo Ferrari, with only a narrow points lead over Shelby, attempted to have the radical new mid-engined Ferrari LM250 homologated for the final championship round at Monza in Italy. When the FIA turned Ferrari down, Ferrari withdrew. The race organizers Auto Club d'Italia, fearing a financial disaster from the withdrawal of the famous Italian team, canceled the event, and Ferrari was crowned World Champion. In the aftermath, Ferrari declared he would never race GTs again, and for 1965 the rivalry with Ferrari was taken up by Ford Motor Company and the Ford GT40, also mid-engined, in the sports car divisions.
