label: Summary
content: The Model 905 was the second of the early aircraft engine designs of the Packard Motor Car Company, located in Detroit, Michigan. Following the Model 299 built in 1915, Packard built three Model 905 engines between 1916 and 1917. The design of both engines followed Packard's twin-six automotive engine. Packard engineers J. G. Vincent and W. B. Stout, under the observation of the U.S. Army, developed the Model 905.
label: Summary
content: The Model 905 was a liquid-cooled V-12 rated at 168 kW (225 shp). Mounted on the platform of a two-ton truck for testing, the propeller projected over the rear end. The propeller thrust drove the truck forward at more than 64 km/hr (40 mph). With no muffler installed, the loud noise attracted a considerable amount of attention around the Packard factory causing the police department to order it off the streets.
