The W121 Ponton 190 was the six-cylinder step up from the four-cylinder 180 — a compact executive saloon that brought smoother power and more prestige to the Ponton range without the cost of a W180 luxury car.
Petrol 190, 190b, and related sedans used the 1.9-liter four-cylinder and later six-cylinder options in the same Ponton body architecture as the W120, while 190 D and 190 Db diesels extended the formula to fleet buyers. This Baureihe covers the four-door Ponton 190 program only — the 190 SL roadster belongs to W121 variant chassis W121.040/042, not the sedan line.
Production ran from 1955 to 1963 across the W121 sedan and diesel range. It was the six-cylinder Ponton for the aspiring executive — smaller than a 220, more refined than a 180.
