The American Automobile and Power Company was an American Brass Era car manufacturer, incorporated in Sanford, Maine, in 1903.^[1] They produced the American Populaire^[1] during 1904 and 1905.^[2]

Starting with a capital of $500,000,^[1] the company incorporated on December 9, 1903. There were eight officers, three from Boston, Massachusetts, the rest locals; Bostonian Henry D. Long was treasurer, Sanfordian Ernest M. Goodall president.^[2]

With a design from Edward O. Mosher,^[2] AEC produced a prototype in a shed in Lawrence, Massachusetts, debuting it at the Boston Automobile Show in March 1904.^[2]

The company offered three models, all with Mosher's 12 hp (8 kW) two-cylinder engine,^[2] on the same 84 in (2134 mm) wheelbase: a $850 roadster, a $950 tonneau (which had an unusual swing-out split front seat),^[2] and a $1000 Cape Cod Tourer.^[2] By contrast, the Yale side-entrance tourer sold for $1000, the Model S $700, the high-volume Oldsmobile Runabout went for $650,^[3] Western's Gale Model A was $500,^[4] a Brush Runabout was $485,^[5] the Black from $375,^[6] and the Success was $250.^[3] At the upper end of the AEC range, a Cole 30 or Colt Runabout was priced at $1500,^[7] while an Enger 40 was $2000.^[5]

While Long bragged, "We could sell one thousand cars in three months if we could make them",^[2] by April 1905, production had ceased and the Maine Alpaca Company had taken over the factory.
