Internally known as W18, the Mercedes-Benz 290 replaced the Type 350/370 Mannheim series in 1933. The new model had a number of innovations such as hydraulic brakes, dual transverse leaf-spring/coil-spring front suspension and a 60HP inline-6 engine.
The engine was a side-valve unit displacing 2,867 cc and could produce 60 bhp.
Six factory bodies were available for the 290 directly from Mercedes-Benz. These included cabriolets A through D, a open four-door touring car and a a four-door sedan. For military application a Kuebelwagen was also available.
In 1934 a long-wheel base variant offered even more body styles including a six-seat touring car and a Pullman limousine. These were fitted with a four-speed manual which increased top speed to 65 mph.
In 1937, the new Type 320 succeeded the 290. A total of 2929 cars were made on the short and long chassis.
