MTU Friedrichshafen GmbH is a German manufacturer of commercial internal combustion engines founded by Wilhelm Maybach and his son Karl Maybach in 1909. Wilhelm Maybach was the technical director of Daimler-Motoren-Gesellschaft (DMG), a predecessor company of the German multinational automotive corporation Daimler AG, until he left in 1907. On 23 March 1909, he founded the new company, Luftfahrzeug-Motorenbau GmbH (Aircraft Engine Manufacturing Corp), with his son Karl Maybach as director. A few years later the company was renamed to Maybach-Motorenbau GmbH (Maybach Engine Manufacturing Corp), which originally developed and manufactured diesel and petrol engines for Zeppelins, and then railcars. The Maybach Mb.IVa was used in aircraft and airships of World War I. The company first built an experimental car in 1919, with the first production model introduced two years later at the Berlin Motor Show. Between 1921 and 1940, the company produced various classic opulent vehicles. The company also continued to build heavy duty diesel engines for marine and rail purposes. During World War II, Maybach produced the engines for Germany's medium and heavy tanks. The company was renamed MTU Friedrichshafen in the 1960s and continued to supply the engines for the Leopard 2 main battle tank. MTU derives from meaning 'Motor (Engine) and Turbine Union'. MTU Friedrichshafen remained a subsidiary of DaimlerChrysler until 2006 when it was sold off to the EQT IV private equity fund, becoming a part of the Tognum Corporation. Rolls-Royce Holdings and Daimler AG acquired Tognum in 2011. In 2014, Tognum was renamed Rolls-Royce Power Systems, having become a wholly-owned subsidiary of Rolls-Royce Holdings. The company manufactures diesel engines for trains, ships, oil and gas installations, military vehicles, agriculture, mining and construction equipment, as well as diesel generators and molten carbonate fuel cells.
