The Mercedes-Benz W 21 was a six-cylinder passenger car launched in 1933 using the name Mercedes-Benz Typ 200. It was one of several Mercedes-Benz models known, in its own time, as the Mercedes-Benz 200 (or sometimes, in this case, as the Mercedes-Benz Typ(e) 200) and is therefore in retrospect more commonly referred to using its Mercedes-Benz works number, “W21”

The side-valve six-cylinder engine had a capacity of 1,961 cc which produced a claimed maximum output of 40 PS (29 kW; 39 hp) at 3,200 rpm. The engine shared its 85 mm (3.3 in) piston stroke length with the smaller 6-cylinder unit fitted in the manufacturer's W15 model, but for the W21 the bore was increased by 5 mm (0.20 in) to 70 mm (2.8 in). The stated top speed was 98 km/h (61 mph) for the standard length and 95 km/h (59 mph) for the long bodied cars. Power passed to the rear wheels through a four-speed manual transmission in which the top gear was effectively an overdrive ratio. The top two ratios featured synchromesh. The brakes operated on all four wheels via a hydraulic linkage.

During the model's final year, Mercedes-Benz announced, in June 1936, the option of a more powerful 2,229 cc 55 PS (40 kW; 54 hp) engine, which was seen as a necessary response to criticism of the car's leisurely performance in long bodied form.


Long undercarriage was known to be average type of undercarriage for model 230, although there were accepted enough orders for beloved among customers 4-place couples of model 200, wide 6-place coupes were bigger that those of previous models. Until 1941, old model 230 remained in assortment in this form.

As a new model 230 (W 153) in 1939 at automobile exhibition appeared new car with renewed coupe, constructed and designed by H. G. Rer, who headed Automobile department in Join stock company Daimler-Bents for 2 years until his death in August 1937. This new model 230 because of war was not appraised in a proper manner, but until 50th remained the base model for construction of models 170 S and 220.
