The Alfa Romeo 20/30 HP is a Berlina / Torpedo from Alfa Romeo, built from 1914 to 1922, as the assembly line was turning motoring into an industry. Under the bonnet: 4.1 . Giuseppe Merosi drew it.
How it came about
The ALFA (later Alfa Romeo) 20/30 HP was a four-cylinder passenger car produced from 1914 to 1922 with three cars using this nameplate: a 4-6-seater tourer, improved version 20/30 HP E in 1914 and 1921 the 20/30 HP ES Sport, a 4-seater sportscar.
The hardware
Power comes from 4.1 other versions carried different engines, listed in the specification table below. It weighs 1000 kg. It shifts through a 4-speed manual. The layout matters: a front engine drives the rear wheels, the classic proportion — long bonnet, cabin set back — that most people picture when they picture a sports saloon or a grand tourer. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Family and rivals
Its family tree is legible: it took over from the 24 HP; assembly was at Portello, Milan, Italy. Its contemporaries in the catalogue — the Dodge 30-35, the Delahaye type 32 coupé-chauffeur, the Lancia Theta-35HP — show what else the money bought that year. Its Alfa Romeo stablemates include the A.L.F.A 12 HP and the A.L.F.A 15 HP.
What it costs now
There is no federal ownership record for the Alfa Romeo 20/30 HP — it predates the complaint database or was never sold in the United States — so MotorJury publishes no running-cost figure for it. For a car of this age the price is set by the collector market and the condition of the individual example, not by a formula.
