MTU MB837 series engine is the first generation armored vehicles series engine, developed by Germany after the Second World War. The full range includes V-6, V-8, V-10 and V-12. Later, due to the increase in engine bore from 165mm to 170mm and the use of different ways on speed and supercharging, developed a total of more than 10 kinds of models with the power range from 290 ~ 1103 kilowatts. These engines have been applied in more than 20 armored vehicles in about 15 countries, with the quantity of more than 14,000 units.
In the early 1950s, Daimler-Benz AG, one of the components of MTU Frederick Hafen, began to develop a high-power MB837 tank engine in accordance with the requirements of the Swiss Ministry of Military Technology. In 1955 the company developed a compact V8 water-cooled turbocharged diesel engine with a capacity of 463 kilowatts (630 horsepower) on the basis of the experience of the development of aero-engine and car engine, which later became the Swiss Pz61 tank power MB837Ba-500 diesel engine. Since then this model power has increased to 485 kilowatts (660 horsepower), once again Switzerland named it the Pz tank power.
