Conceived as a good-luck charm in the heroic period of motorsports, the Quadrifoglio (four-leaf clover) - written with a capital 'Q' - has distinguished the sports and industrial history of Alfa Romeo. The car maker first gained acknowlegement for the quality and performance of its vehicles.

The Quadrifoglio emblem was placed on high-performing models built from the '60s to the '80s. Some had the symbol on their bodywork, even though it did not appear in their names - such as the Giulia Sprint GT Veloce or the 1750 GT Veloce - while others, from the Eighties onward, included Quadrifoglio in their official names, such as the various versions of the 33 Quadrifoglio Verde or the 164 Quadrifoglio Verde.

Today, the standard-bearers in the new Alfa Romeo generation are the Giulia and Stelvio models, both of which bear the legendary Quadrifoglio badge, which certifies their qualities in terms of class-topping performance, handling and weight/power ratio, specific external and internal features, exclusive powerplants and a genuine Alfa Romeo sound. The Giulia and Stelvio Quadrifoglio, with their all-aluminium 2.9-litre V6 bi-turbo petrol engines deliver 510 horsepower and 600 Nm of torque and are fitted with an 8 speed automatic transmission.
