The Mercedes-Benz W02 was a midsize six-cylinder two-litre-engined automobile introduced by Daimler-Benz at the Berlin Motor Show in October 1926.

The new company's models for 1926 were unencumbered by an excess of technical sophistication, but came from a company with a long-standing reputation for quality: serious teething problems afflicting the early cars were the focus of conflict between Daimler-Benz Chairman, Wilhelm Kissel and the Technical Director responsible for the new models: Porsche's employment contract was not renewed beyond 1928, which led to acrimonious litigation.

[3] The side-valve six-cylinder 1,988 cc engine delivered a maximum output of 38 PS (28 kW; 37 hp) at 3,400 rpm, which translated into a top speed of 75 km/h (47 mph).

Power was transmitted via a three-speed manual transmission to the rear wheels, which were fixed to a rigid axle suspended from semi-elliptic leaf springs.

The relaunched car, now branded as the "Mercedes-Benz Typ Stuttgart 200" retained the 1,988 cc side-valve engine fitted the previous year.

The compression ratio was substantially raised from 5 : 1 to 6.2 : 1, and the carburetor type (though apparently not its diameter) was changed from a "Zenith 30 HKG" to a "Solex 30 MOHLT".

1929 also saw the introduction of the Mercedes-Benz W11, which in effect was virtually the same car, but offered with a larger engine and a wider range of body options.
