The Curved Dash Olds Runabout was the first high volume mass-produced automobile. It was introduced by the Olds Company in 1901 and produced through 1907. The engine turned at 50 R.P.M. - one chug per telegraph pole. The car was made under license in Germany as the "Polymobile" and "Ultramobile."
Oldsmobile introduced their Model 6C in April of 1904 and would remain in production until the end of the year. Its design was similar to the model it was replacing - the model R - but they were different in many details. The Model 6C was a little longer, had heavier running gear, and there were drum and hub brakes on the rear wheels. Even though it received new brakes, it did keep its brake in the rear axle differential housing. The car became stiffer and stronger, and the body was built entirely of wood. The paint was black with a bright red trim. The standard body trim was a curved dash runabout with seating for two.
