Alfa Romeo 24 HP
The Alfa Romeo 24 HP represents a fundamental chapter in the history of the Milanese brand, marking the early years of what would become one of Italy's most prestigious automobile manufacturers. Launched in 1910, this automobile embodies the ambitious beginnings of A.L.F.A. (Anonima Lombarda Fabbrica Automobili), the company created on June 24, 1910 following the takeover of assets from the defunct Darracq Italiana. Under the direction of engineer Giuseppe Merosi, recruited from Bianchi, the nascent company sought to establish its credibility in the Italian automotive market by offering a modern and powerful vehicle capable of competing with European productions of the era. The 24 HP immediately distinguished itself with its inline four-cylinder engine developed by Giuseppe Merosi himself. This innovative powerplant for the time produced approximately 42 horsepower at 2200 revolutions per minute, thanks to a displacement of 4084 cc. The engine featured side-valve distribution and high-tension magneto ignition, advanced technical characteristics for 1910. This design allowed the 24 HP to reach a respectable top speed of approximately 100 km/h, a remarkable performance for a touring automobile of this period. The robust and well-designed chassis utilized stamped steel side members and semi-elliptical leaf spring suspension at both front and rear, ensuring satisfactory road handling on the often rudimentary roads of the era. The 24 HP was offered in several body configurations, following the tradition of the time when chassis were delivered to coachbuilders for body fitting. Customers could choose between torpedo, limousine, or landaulet versions, adapted to the varied needs of an affluent clientele. The positioning of the 24 HP clearly targeted the Italian bourgeoisie and automobile enthusiasts seeking quality manufacturing and performance. Production took place in the new facilities at Portello in Milan, where the company had established its headquarters. Between 1910 and 1911, approximately 50 units were assembled, a modest figure reflecting both the limited capabilities of a young manufacturer and the still-restricted automotive market of pre-World War I Italy. The reception of the 24 HP was generally positive in the specialized Italian press, which praised the build quality and honest performance of the model. Several examples participated in reliability trials and local races, contributing to forging the brand's emerging sporting reputation. In 1911, the 24 HP evolved slightly with detail improvements, particularly in the lubrication system and transmission. The legacy of the 24 HP is considerable: this model established the technical and philosophical foundations of Alfa Romeo, demonstrating from the outset the brand's commitment to quality engineering and performance. Giuseppe Merosi, with this first creation, laid the groundwork for a lineage that would soon include the legendary 40-60 HP and RL models. The 24 HP remains today an extremely rare collector's item, symbol of the glorious origins of a mythical brand.

Technology
Technologies, engines and platforms
The Alfa Romeo 24 HP is based on an inline four-cylinder engine of 4084 cc designed by Giuseppe Merosi, developing 42 horsepower at 2200 rpm with side-valve distribution and magneto ignition. The chassis uses stamped steel side members with semi-elliptical leaf spring suspension on both axles. The transmission includes a cone clutch and a four-speed manual gearbox. The braking system acts on the rear wheels and on the transmission. The mechanical assembly prioritizes robustness and reliability, essential characteristics for road conditions of 1910. Engine lubrication is provided by a combined splash and pressure system.
Tires and wheels
Tire and wheel compatibility
For the Alfa Romeo 24 HP (1910-1911), wheel and tire dimensions correspond to period standards with wire-spoke wheels and tire casings. It is essential to consult a specialist in historic vehicles to determine exact specifications according to original configuration.
