The Rotary Motor Vehicle Co.
Boston, MI
1904-1905

The Rotary and sometime known as the Intrepid was a American Automobile with a strange engine with two crankshafts, two connecting rods and one piston. Despite the name the Rotary engine it was not a revoling engine.

The Boston, MA based Rotary Motor Vehicle Co. was built in 1904 and 1905.

The Rotary automobile was produced as a Roadster only. The company specialized in boat engines, but they got into the automobile business with their strange and unorthodox one cylinder eight horsepower engine.

The Rotary engine was claimed to be completely vibrationless and was entirely different from other engines of 1904 and 1905. Two cylinders and one crankshaft was the accepted theory for engine construction. However the Rotary produced an engine that worked very well with two crankshafts. The crankshafts were contra-rotating, weighted and each had a piston rod. Perfect synchronization was necessary in order to produce smoth easy power.
