The Mercedes-Benz 190b was another gasoline powered variant of the W121 that was introduced in 1959 as an upgrade of the W121 190. The 190b was only built from the factory in a four door sedan body style, but a coachbuilt station wagon by Binz & Co. was sold through Mercedes dealerships. The 190b was launched with Mercedes' M121 BI b engine, which was a 1.9L inline four that generated 75hp. Built until 1961, the W121 Mercedes-Benz 190b saw a total of 28,463 examples produced.
