    Co-designed in mid-1917 by Jesse Vincent of Packard Motor Car and Elbert Hall of Hall-Scott Motor Car, the Liberty used only proven components to ensure workable engines in the shortest time. The Model L-8 was the first Liberty engine. However, power requirements made it obsolete before entering service, leading to the twelve-cylinder Liberty.
