Delage does not build many cars like the Delage D4: a "Coach standard" 2-doors/4-seats / "Berline" (saloon/sedan) 4-doors/4-seats / "Coupé" 2/3 seats / "Coach luxe" 2-doors/4-seats / "Torpédo roadster" (cabriolet) 2-seats / "Cabriolet with 1480 , built from 1933 to 1934 when streamlining and independent suspension were arriving together.
The background
The Delage D4 was a 4-cylinder compact luxury car in the 8CV car tax band produced by the manufacturer between 1933 and 1934.
The engineering
Under the skin sits 1480 . The gearbox is a Four-speed manual. The wheelbase is 2800 mm. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Where it sits
Where it sits in Delage's history is not in doubt: it was built at Levallois-Perret. On a showroom list of its day it stood against the Bugatti Type 57, the Chevrolet Suburban, the Lancia Augusta. Its Delage stablemates include the Delage D12 and the Delage D6.
The money
There is no federal ownership record for the Delage D4 — 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.
