Quadrifoglio is the Italian word for a four-leaf clover. In the 1923 Targa Floria, driver Ugo Sivocci put the symbol of good luck on his Alfa Romeo RL, and he won the race. That was the beginning of the association between Alfa and the Quadrifoglio. The brand intends to celebrate the 100th anniversary of this symbol for its motorsport success throughout 2023. 

The four-leaf clover also appeared on Alfa Romeo's grand prix racers in the 1920s as a way to distinguish the team's cars from the same vehicles from Scuderia Ferrari wearing the Prancing Horse emblem. Later, the Quadrifoglio was on the models that won the first two Formula 1 World Championships in 1951 and 1952. In the 1960's, the company began using the logo on its sporty, road-going vehicles.
