The Stoewer 8 Type S 8 is a car of the upper middle class that was made by car company, Stoewer. It was brought out in 1928 as Bernhard Stoewer wanted to offer his customers something special, because he thought that it was the only way  he could win against foreign competition.

The Stoewer 8 Type S 10 had a  2.5-litre engine (producing 50 hp), replaced the S 8, the Stoewer Type G 15 with a 4-litre engine (producing 80 hp) replaced the G14. There was also a version of the G 15 with short wheelbase called the G 15 K. The S 10 was brought it in 1930 and 790 copies were made. The number of G 15 (all versions) was 650 at the end of 1933.

In 1930, as successor to the Model 10 S, the Stoewer Marshal Type M 12 was introduced. Its engine had a capacity of 3 litres and produced 60 hp. Until 1934 280 cars were made, 800 more cars were produced between 1935 and 1936 to the Reichswehr delivered.
