The Mercedes-Benz 180 was the gasoline powered variant of the W120. Introduced in 1953, the 180 was a rear wheel drive car offered from the factory in a four door sedan body, although coachbuilt station wagon bodies were built by Binz & Co and sold through Mercedes dealers. The 180 went through four evolutions, the 180 (1953-1957), 180a (1957-1959), 180b (1959-1961), and 180c (1961-1962). Though these evolutions were largely based on the engine offered, the 180 saw small changes to the body and interior over the course of production, such as a slightly wider grill, a sleeker front bumper, and slightly larger taillights. Initially, the 180 was fitted with Mercedes' M136 engine, which was a 52hp 1.8L inline four, but for the 180a, Mercedes introduced their M121 engine, a 65hp 1.9L inline four. This same engine saw small updates for the 180b and 180c, with small torque and horsepower increases. Production of the W120 Mercedes-Benz 180 ended in 1962 with a total of 118,234 examples built.
