The Mitsubishi Vulcan engine, identified by the code 2G2, is an iron-block twin cylinder engine with three main bearings, built by Mitsubishi Motors for kei car class vehicles from September 1972. It was an overhead camshaft design, and superseded the older two-stroke 2G1 series. The 2G2 was in turn replaced by the Multi-valve 3G8 three-cylinder series.

"MCA" stood for "Mitsubishi Clean Air", reflecting Japan's new air quality laws. The MCA-II was cleaner yet, and with balance shafts it also offered a much smoother run, at the loss of a few horsepower. The Sports engine did not meet the stricter emissions laws, which led to the demise of the Skipper.
