Saturday 23rd March 1963
Ferrari dominated, taking the first six places in the Sebring 12 Hour World Sports Car Championship race. John Surtees and Ludovico Scarfiotti drove a new 3.0 liter 250P to victory with another 250P of Willy Mairesse/Nino Vaccarella second. The American challenge of Cobra, Corvette and Chaparral collapsed and the new Jaguar E-Type of Bruce McLaren and Walt Hansgen had brake trouble to set up the Ferrari sweep.
