The Unnamed Patent Car was the first car produced by German engineers Daimler and Mercedes-Benz, who founded Daimler Motoren Gesellschaft (DMG). The first car was sold in 1880.

From 1869, Maybach and Daimler often worked as engineers in other companies at the same time, designing engines and accessories to engines for these companies. Finally, they worked together on the staff of the engine manufacturer, the Deutz-AG-Gasmotorenfabrik in Cologne that was half-owned by Nikolaus August Otto. In 1880 Daimler was fired by Otto and Maybach soon quit, whereupon, they began working as partners.

Unknown to Otto, Daimler, and Maybach, during 1878 Karl Benz, in Mannheim, was concentrating all his efforts on creating a reliable two-stroke gas engine. Benz finished his engine on 31 December 1878, New Year's Eve, and was granted a patent for his engine in 1879 and along with the design and sale of static engines, he began to design a vehicle that could be motorized.
