Oldsmobile Model M

The Oldsmobile Model M was a four-seat passenger car produced by Oldsmobile in 1908, offered as a mid-range alternative to the Model R Curved Dash runabout that appeared in 1901, replacing the Model A. It was the junior sedan to the first six-cylinder sedan, the Oldsmobile Model Z, also introduced in 1908, but was larger than the Oldsmobile Model X. The Model M was equipped with a side-valve, in-line 336 cubic inch four-cylinder engine developing 36 horsepower, installed in the front and driving the rear wheels through a transmission shaft.
