Alfa Romeo does not build many cars like the Alfa Romeo 6C with Straight-six, built from 1927 to 1954 the vintage years, when coachbuilders still shaped most of what was sold.
The background
The Alfa Romeo 6C name was used on road, race, and sports cars produced between 1927 and 1954 by Alfa Romeo; the "6C" name refers to the six cylinders of the car's straight-six engine. Bodies for these cars were made by coachbuilders such as James Young, Zagato, Touring Superleggera, Castagna, and Pinin Farina. Beginning in 1933 there was also a 6C version with an Alfa factory body, built in Portello.
In the early 1920s Vittorio Jano received a commission to create a lightweight, high performance vehicle to replace the Giuseppe Merosi designed RL and RM models. The car was introduced in April 1925 at the Salone dell' Automobile di Milano as the 6C 1500. It was based on Alfa's P2 Grand Prix car, using a single overhead cam 1,487 cc in-line six-cylinder engine, producing 44 horsepower. In 1928 the 1500 Sport was presented, which was the first Alfa Romeo road car with double overhead camshafts.
The engineering
Under the skin sits Straight-six. Kerb weight is 1250 kg. 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.
Where it sits
Where it sits in Alfa Romeo's history is not in doubt: the Alfa Romeo RM came before it; the Alfa Romeo 1900 followed it; it was built at Portello Plant, Milan, Italy. On a showroom list of its day it stood against the Tatra 26, the Tatra 15, the Bugatti type 38 torpedo. Its Alfa Romeo stablemates include the A.L.F.A 12 HP and the A.L.F.A 15 HP.
The money
There is no federal ownership record for the Alfa Romeo 6C — 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.
