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 SAME, 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. 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. Deutz-powered air-cooled engine 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
