The 1906 Grand Prix de l’Automobile Club de France was the very first race, as successor to the Gordon Bennet Cup. This first GP was won by a Renault with Ferenc Szisz at the steering wheel. An interesting technical feat was the first-ever application of detachable wheel rims; in French „jantes amovibles“. These enabled a reduction of pitstop time to a mere 3 minutes, which was the main reason for Szisz winning this Grand Prix. Introduction of the Grand Prix by the l’ACF (French Automobile Club) stood under much critisism, mostly by non-French racing nations. A short summary on different comments and opinions will be given here too.
