In open-road endurance races across Europe such as the Mille Miglia, Tour de France and Targa Florio, which were often run on dusty roads, the need for fenders and a mechanic or navigator was still there. As mainly Italian cars and races defined the genre, the category came to be known as Gran Turismo (particularly in the 1950s), as long distances had to be travelled, rather than running around on short circuits only. Reliability and some basic comfort were necessary in order to endure the task.
