Liberty L-8 (Packard) V-8 Engine

Liberty L-8 (Packard) V-8 Engine

     

The Liberty's purpose was American mass production of standard units when the U.S. entered World War I. Co-designed in a week in mid-1917 by Jesse Vincent of Packard Motor Car and Elbert Hall of Hall-Scott Motor Car, with a planned series of 4-, 6-, 8-, and 12-cylinder models, this Model L-8 was the first Liberty engine. However, power requirements made it obsolete before entering service, and the twelve-cylinder Liberty was then built.

To ensure workable engines in the shortest time, only proven components were used. The Liberty's success was due entirely to the fact that the best engineers, production experts, and manufacturing facilities were provided to the Government. Leading automotive manufacturers, including Ford, Lincoln, Packard, Marmon, and Buick, built the engines.

The Liberty 12 Model A powered numerous aircraft including the de Havilland DH-4, the Navy-Curtiss NC-4, Fokker T2, Loening Model 23, Douglas World Cruiser, Douglas M-1 Mailplane, and Curtiss H-16 flying boat.
