The Mitsubishi KE engine is a range of engines produced by Mitsubishi Motors during the 1960s and early 1970s. They were extensively used in the various Colt-branded vehicles the company produced from 1963. As a large scale manufacturer, Mitsubishi had a wealth of experience building engines, both gasoline and diesel, in V and straight engine block configurations during the war. One of their many examples was the air-cooled A6120VDe air-cooled inline 6-cylinder 14.4 L diesel and the SA12200VD air-cooled V-12 diesel (21.7 litres).
