Following the announcement of the FIA Formula One 2013 Calendar by the World Motor Sport Council in Paris the FIA World Endurance Championship has revised the date of the 6 Hours of São Paulo after the original date for the Belgian Grand Prix changed from the 1 September to the 25 August.

In order to avoid a clash with the Grand Prix at Spa-Francorchamps, the 6 Hours of Sao Paulo will now take place on Saturday 31 August, which was the original date agreed with the promoter of the event Emerson Fittipaldi.
