The was an advanced design overhead camshaft four-cylinder EA831 engine bought from Audi/Volkswagen 1977 through 1979. Though a small engine, its advanced design created reasonable power for its size and due to being an OHC engine, it had a high redline. This engine was also used in the Audi 100, Volkswagen LT van, and Porsche 924. The engine was assembled to AMC specs in the US at a specifically purchased AMC assembly plant. Specifications are different from the Audi/VW/Porsche assembled engine. AMC used a carburetor and standard points ignition as well as slightly larger clearances.
