text: # 12 Heures de Sebring 1973
  
  Les 12 Heures de Sebring 1973 sont la 22e édition de l'épreuve et la 1re manche du championnat IMSA GT 1973. Contrairement aux précédentes éditions depuis 12 Heures de Sebring 1952, l'épreuve ne compte plus pour le championnat du monde des voitures de sport. Elles ont été remportées le 24 mars 1973 par la Porsche Carrera RSR $n^o$ 59 pilotée par Peter Gregg, Hurley Haywood et Dave Helmick.
  
  ## Circuit
  
  Les 12 Heures de Sebring 1973 se déroulent sur le Sebring International Raceway situé en Floride. Il est composé de deux longues lignes droites, séparées par des courbes rapides ainsi que quelques chicanes. Le tracé actuel diffère de celui de l'époque. Ce tracé a un grand passé historique car il est utilisé pour des courses automobiles depuis 1950. Ce circuit est célèbre car il a accueilli la Formule 1.
