Cadillac Models & History M 1908
TheMODEL M was built only as a delivery vehicle. It was the same as the 1907 delivery except that prices now included two oil side lamps, an oil tail lamp, and a bulb horn. Headlamps were not included as standard equipment on Cadillacs until 1910. Also it did not have the longer wheelbase or running boards found on the Model S or Model T.

DRIVETRAIN OPTIONS
- On the models M, S & T, different combinations of 9 or 10 tooth driving sprocket with 31, 34, 38, 41, or 45 tooth driven sprocket gave ten possible ratios from 3.1:1 to 5:1.
-
Driven Sprocket 31 34 38 41 45 9 tooth drive sprocket 3.44 3.78 4.22 4.56 5.00 10 tooth drive sprocket 3.10 3.40 3.80 4.10 4.50 - Lower ratios for runabout to be run on smooth, level roads to higher ratios for loaded Delivery to be run on rough, hilly roads.
- Instructions for changing sprockets were available for owners, but the change involved disassembly of the transmission and rear axle — definitely not a “quick-change” set-up.
