The Hudson Motor Car Company was founded in Detroit, Michigan, in 1909 by engineers including Howard Coffin and Roy Chapin, with financial backing from department-store owner Joseph L. Hudson. The company built automobiles from 1909 until 1954, when it merged with Nash-Kelvinator to form American Motors; the Hudson name itself was retired in 1957.

Hudson is remembered for real engineering advances, most notably the 1948 step-down unit-body chassis, which lowered the car's center of gravity and improved handling for its time, and the Twin H-Power inline six-cylinder engine setup. These developments contributed to the Hudson Hornet's strong performance in early-1950s stock car racing. Engine options across the lineup included 202, 232, 262, and 308 cubic-inch inline sixes, with the Hydra-Matic automatic transmission available as an option.

The manuals offered here cover the engine and drivetrain systems used in these classic Hudson models. Typical coverage includes engine rebuild procedures for the inline-six engines, transmission and Hydra-Matic service, electrical system and wiring diagrams, torque specifications for engine and chassis fasteners, and the diagnostic steps needed to track down running or electrical problems in an older vehicle.

These manuals are written for restorers bringing a Hudson back to original condition, independent garages that service classic cars, and hobbyists maintaining a Hornet, step-down model, or other Hudson for regular driving or show use. With factory-style detail on engines, transmissions, and wiring, the manuals support accurate, informed work on these historically significant cars.
