12 Hours of Casablanca

The 12 Hours of Casablanca was a sports car endurance race organised on the route of the future Ain-Diab Circuit in Morocco.

Casimiro de Oliveira and Alberto Ascari had crashed during practice in their Ferrari 375 MM and had to change teams and cars.

[7] Luckily for Ascari, he joined Luigi Villoresi in the Ferrari 500 Mondial and arrived second at the finish line in the actual race.

[8] The 500 Mondial that won its class, was based on a Ferrari 625 TF berlinetta chassis that was destroyed in a fire, rebodied by Scaglietti and equipped with a 2.0-litre engine.

In 1957, the race route was refitted and increased to 7.618 kilometers thanks to the Royal Automobile Club of Morocco.
