Vehicle model
Alfa Romeo 40-60 HP
The Alfa Romeo 40-60 HP represents one of the first emblematic vehicles from the Italian marque, designed during a pivotal period when racing automobiles and grand touring cars were one and the same. Launched in 1913, this high-end automobile embodied the ambition of A.L.F.A. (Anonima Lombarda Fabbrica Automobili), the company preceding the official creation of Alfa Romeo in 1915. The 40-60 HP model derived its name from its fiscal and actual horsepower, a period convention that designated the impressive capabilities of its engine. Designed by engineer Giuseppe Merosi, a central figure in technical development at A.L.F.A., the 40-60 HP relied on a robust chassis and daring mechanics for the era. The four-cylinder cast-iron engine developed approximately 70 actual horsepower, considerable power for the period preceding World War I. This engine adopted side-valve distribution and a displacement of 6082 cc, guaranteeing generous torque and reliability on difficult roads. The design prioritized solidity and endurance, essential qualities for endurance competitions and rallies that were gaining popularity. The positioning of the 40-60 HP targeted an aristocratic and sporting clientele, capable of appreciating both the performance and prestige associated with the Milanese brand. The chassis could receive different coachwork, ranging from sporty torpedo to more formal coupé, according to the desires of wealthy buyers. This flexibility characterized the pre-war automobile market, where bare chassis were delivered to independent coachbuilders for custom bodywork. Production of the 40-60 HP was interrupted by the Great War, during which A.L.F.A.'s facilities were requisitioned for the military effort. After 1918, under the new direction of Nicola Romeo who gave his definitive name to Alfa Romeo, a few examples of the 40-60 HP were still assembled, mainly from stored pre-war components. Total production remained confidential, estimated between 20 and 25 examples according to historical sources, making this model one of the rarest from the brand. On the competitive front, the 40-60 HP participated in several Italian endurance events, demonstrating its mechanical robustness against the terrible road conditions of the era. These sporting successes, though modest compared to Alfa Romeo's subsequent triumphs, nevertheless contributed to forging the brand's nascent sporting reputation. The legacy of the 40-60 HP resides in its foundational role for Alfa Romeo. It established the philosophical foundations of the brand: performance, elegance, and exclusivity. The lessons learned on this model directly influenced subsequent developments, notably the celebrated RL and 6C of the 1920s. Today, the rare surviving examples are considered treasures of Italian automotive heritage, precious witnesses of an era when the automobile embodied technological adventure and mechanical audacity.

Technology
Technologies, engines and platforms
The Alfa Romeo 40-60 HP's technology relied on a 6082 cc inline four-cylinder engine with side valves, developing approximately 70 actual horsepower. Single-shaft distribution and magneto ignition ensured reliability and maintenance simplicity. The chassis used stamped steel frame rails, rigid axle suspension with semi-elliptical leaf springs front and rear. The four-speed manual transmission delivered power to the rear wheels via a central driveshaft and open differential. The braking system relied exclusively on mechanical drums on the rear wheels, complemented by a handbrake. This technical architecture prioritized robustness and ease of maintenance characteristic of pre-war luxury automobiles.
Tires and wheels
Tire and wheel compatibility
For the Alfa Romeo 40-60 HP, tire and wheel dimensions varied depending on the coachwork and production year. It is essential to verify the exact specifications of your example with a period vehicle specialist.
