''Cars: Early and Vintage, 1886-1930''. (London: Grange-Universal, 1985) The technical director, Gottlieb Daimler, was eager to produce automobiles. In the middle of the 1870s, it was suggested that he transfer to the company's St. Petersburg factory to reduce his influence. He resigned, taking Wilhelm Maybach with him. Deutz also produced agricultural machines such as

. In 1884 Edouard Sarazin, a Belgian patents lawyer and pioneer of automotive engineering, represented 'Gasmotorenfabrik Otto & Langen' (Deutz AG) and acquired the licence to build Deutz engines in France, which he duly contracted to Perin, Panhard & Cie (later Panhard et Levassor) in Paris. Around 1886/7, he similarly acquired licences to build Daimler engines. His untimely death in 1887 left his widow Louise to develop the business relationships and complete the partnership negotiations.Motor Museum in Miniature - Louise Sarazin

'' McGill-Queen’s University Press, Montreal 1976, ISBN 0-7735-0264-5.Reinhard Seiffert: ''The era of Gottlieb Daimler''(Die Ära Gottlieb Daimlers). Famous people who have worked for Deutz include Eugen Langen, Nicolaus Otto, Gottlieb Daimler (from 1872 until 1880), Wilhelm Maybach (from 1872 until 1880), Prosper L'Orange (from 1904 until October 1908), Ettore Bugatti (in 1907), and Robert Bosch. During World War II, the company was ordered to produce artillery and operated under the name Klöckner Humboldt Deutz AG (KHD). The factory was almost destroyed by an air raid on the night of the 3rd and 4th of July 1943 (→ Bombing of Cologne in WW II). From 1892 to 1970, Deutz built locomotives in the power range from 4 HP to 2000 HP; until 1927 with gasoline engines, and from 1927 increasingly with diesel engine drive. Commercial vehicles powered by Deutz engines were popular from 1960 to 1980. Fire engines built by '' Magirus'' in Ulm, Southern Germany, used an M-shaped logo, with the steeple of the world's tallest church, the Ulm Minster, in its center. After the Magirus-Deutz merger, the company continued to use this logo even though the twin towers of the Cologne Cathedral can be seen from the company headquarters. Deutz's head office is in the Porz district of Cologne and, as of 2004, was manufacturing liquid and air-cooled diesel engines. The larger engines in the Deutz range were manufactured in Mannheim at a production facility that once belonged to Süddeutsche Bremsen-AG as MWM-Diesel. Deutz also has production facilities in other countries, including Spain, and a joint venture production facility in China. After Deutz took over, the plant specialized in marine engines. This facility now produces engines for marine and power generation, which can run on either fuel oils or fuel gases (including landfill gas). In 1995 Deutz sold its agricultural machinery division – Deutz-Fahr – to the Italian company

, forming SAME Deutz-Fahr. In February 2022, CEO Frank Hiller was dismissed and replaced by the supervisory board. Sebastian Schulte replaced him as the interim CEO & CFO. The Chairman of the Supervisory Board, Bernd Bohr, resigned. His successor was Dietmar Voggenreiter.

The engines

Deutz engines are available in the power range of 5 to 500 kW, with air, oil or water cooling and with life expectancy of 20,000 to 30,000 running hours TBO (Time Between Overhauling) on rebuilt and brand-new units. Parts and services are available worldwide. A network of distributors in the United States and Canada was established a few years ago, providing parts and services in North America. Deutz-powered air-cooled machines are well-suited for many applications since they cannot freeze or boil over during normal operation. Deutz also manufactures oil-cooled engines. These can provide the same power as other engine designs, but in a smaller package, since they do not require the additional space to house a radiator. Deutz also makes engines with a tandem oil cooler/radiator configuration; these also do not require antifreeze or coolant agents. Deutz also sells a line of economic liquid-cooled engines. In 2007, the "Deutz Power Systems" division was sold to 3i, and Deutz AG now concentrates on producing and selling compact engines under the Deutz brand only. They focus on manufacturing engines only for the customer, without competing for the entire piece of finished machinery. On October 1 2008, the former ''Deutz Power Systems'' division received a new, old, name MWM (Motoren Werke Mannheim AG). Karl Benz established the company in 1871. After splitting the engine business from Benz AG, it became Motoren-Werke Mannheim AG. Klöckner-Humboldt-Deutz AG took over in 1985, later becoming Deutz AG. After spinning off Deutz Power Systems, the company has made a full circle back to MWM. In 2012, SAME Deutz-Fahr sold 22 million shares, the majority of its holding in Deutz AG, to Volvo, making of it the largest shareholder at just over 25%. SAME Deutz-Fahr retained 8.4% equity in the company. In 2017, Deutz acquired Torqeedo GmbH, specialist for integrated electric and hybrid drives for boats. Volvo sold all of its ownership stakes in Deutz in the same year.
