Description

The Alfa Romeo 20/30 HP ES Sport, produced from 1921 to 1922, played a key role in Alfa Romeo’s early development as a manufacturer of luxury sports cars. It was introduced during a period of transition for the company, following its acquisition by Nicola Romeo, which saw the brand evolve from A.L.F.A. to Alfa Romeo. The car was powered by a 4.2-litre inline-four engine that generated around 67 horsepower, allowing it to reach a top speed of approximately 81 mph (130 km/h). This performance was considered impressive for the time, underscoring the vehicle’s sporting credentials.

The 20/30 HP ES Sport featured a 4-speed manual transmission, providing a level of control and driving engagement that appealed to enthusiasts. Its design was elegant, with a long, sleek body and a large engine compartment, typical of luxury cars from the early 1920s. The chassis was lightweight and designed to accommodate custom bodies from coachbuilders, making it a highly customizable model. The “ES” in its name, standing for “Evoluzione Sport,” reflected the car’s status as a more advanced, sport-oriented version of earlier Alfa Romeo models. This car helped solidify Alfa Romeo’s reputation for producing high-performance sports cars and laid the groundwork for the brand’s future success in motorsport and luxury automobile markets.
