2-door saloon, 4-door saloon.

Unlike later D1-12 (not sold in Britain) this is a pure Delage with no Delahaye influence, and the same chassis and 75mm x 74mm cylinder dimensions as the D6-11. Abbreviated 110ins wheelbase. Unsuccessful competition for the mid-range Peugeots and seldom seen anywhere. Disc wheels and factory bodies on most D4s.
