Alfa Romeo 12 HP
The Alfa Romeo 12 HP represents one of the very first models produced by the young Italian company A.L.F.A. (Anonima Lombarda Fabbrica Automobili), founded in June 1910 in Milan. This automobile truly marks the beginnings of what would become one of the most prestigious brands in Italian automotive history. The A.L.F.A. company arose from the ashes of the Italian subsidiary of Darracq, a French enterprise that had experienced commercial difficulties in Italy. A group of Milanese investors and entrepreneurs, including Ugo Stella, decided to take over the Portello factory and create an authentically Italian brand. The 12 HP was introduced in 1910 as the entry-level model of the new brand, intended for a bourgeois clientele seeking a reliable and elegant automobile. Designed by engineer Giuseppe Merosi, freshly recruited from Bianchi, this sedan embodied the technical philosophy that would characterize Alfa Romeo for decades: prioritizing performance and mechanical refinement. The designation "12 HP" refers to the vehicle's fiscal horsepower according to Italian standards of the era, a common classification in the early twentieth century. Stylewise, the 12 HP displayed the typical aesthetic codes of the Belle Époque automotive era: a tall and narrow body, large-diameter spoked wheels, an elongated hood, and a distinctive vertical grille. The lines were elegant yet functional, reflecting the pragmatic approach of manufacturers during this pioneering period. The car was generally offered in torpedo or sedan configuration, with seating for four to five passengers. Construction employed noble materials such as wood for the body framework and leather for the interior. The market positioning of the 12 HP in Italy was that of a medium-to-upper quality car, competing with other local manufacturers such as Fiat, Itala, or Lancia. Alfa Romeo sought from its beginnings to distinguish itself through a sportier and more refined approach, foreshadowing the reputation the brand would develop in subsequent years. Production remained artisanal and limited, as was generally the case for automobiles of this era, with each vehicle meticulously assembled in the Portello workshops. The commercial career of the 12 HP was relatively brief, with production ending around 1911 to make way for more powerful and sophisticated models such as the 15 HP and 24 HP. Nevertheless, this inaugural model played a fundamental role in Alfa Romeo's history by establishing the technical foundations and quality reputation upon which the brand would build its future success. Although few examples have survived to the present day, the 12 HP remains an important historical milestone, testifying to the ambitions and craftsmanship that would animate Alfa Romeo throughout the twentieth century and beyond.

Technology
Technologies, engines and platforms
The Alfa Romeo 12 HP is powered by an inline four-cylinder engine of modern design for the era, developing approximately 12 Italian fiscal horsepower (approximately 18-20 actual horsepower). The engine block adopts a side-valve architecture, a widespread technical solution in the early 1910s. Displacement is around 2.4 liters, offering sufficient torque to propel this sedan weighing approximately 800 kilograms. Transmission is through a three or four-speed manual gearbox, with cone or disc clutch depending on versions. The chassis uses traditional ladder-frame steel construction, with leaf spring suspensions front and rear. Braking operates only on the rear wheels, via mechanically operated drum brakes actuated by cables.
