The NSU company, founded in 1886, specialized in the production of bicycles, which were very popular at that time. In 1900, the NSU management decided to start producing motorcycles, and by 1905 it was ripe for the automotive industry. Licensed car assembly was started under a contract with the Belgian company Pipe, then the company released the 6 / 10PS model, developed by Otto Pfänder, which had a 4-cylinder engine.
Subsequently, the NSU company presented a number of large models with engines with a displacement of up to 2.6 liters, then tried to produce a subcompact car with a 2-cylinder power plant, but it turned out to be not very popular. But released two years later, in 1911, the model with a 4-cylinder 1.1-liter engine received very high demand, as well as the 1.2-liter that followed. In 1913, the company introduced the most powerful car in its history, equipped with a 3.4-liter engine. The model became extremely popular, and the company produced it until 1926, with a break only during the active hostilities of the First World War.
In 1927 the company moved to a new plant in Heilbronn, but after 2 years it had to sell it due to financial problems. The company mothballed production, and only in 1958 was able to return to work again, presenting the Prinz minicar, which later developed into a series of models.
In 1963, NSU introduced the Spider, which was the world's first rotary piston engine. Four years later, the company released the P-80, which in many ways was a real breakthrough, but the problems of the rotary engine and design flaws hit the company's reputation hard.
In 1969, NSU and Audi merge under the wing of the Volkswagen Corporation. The firm produces several more models, including the K-70 sedan, which was based on the Po-80. In 1977 Volkswagen decided to close the NSU brand.
