Opel automobile GmbH is a German carmaker and has been a subsidiary of Groupe PSA since August 1, 2017. In March 2017, French carmaker Groupe PSA agreed to acquire Opel from general motors. The acquisition was approved by European Commission regulators in July 2017. Opel is headquartered in rselselsheim am Main, Hesse, Germany. The company designs, designs, manufactures and distributes Opel branded passenger cars, light commercial vehicles and vehicle parts for distribution in Africa, Asia, Europe and South America. Opel designed and manufactured vehicles are also sold under the Vauxhall brand in the UK, the Buick brand in the US, Canada, Mexico and China, and the Holden brand in Australia and New Zealand.

The history of Opel can be traced back to a sewing machine manufacturer founded in 1862 by Adam Orbaugh (Adam Opel). The company began to produce bicycles in 1886 and the first car in 1899.

Opel became a company limited by shares in 1929 (German: Aktiengesellschaft); in the same year, General Motors acquired a majority stake in Opel. General Motors began full control in 1931.

In the 1970s and 1980s, the Vauxhall and Opel series were rationalized to a consistent range across Europe.

After GM decided to withdraw its Chevrolet brand from Europe from 2016, Opel withdrew from China in early 2015, where it has 22 dealer networks.
