While the name is world-famous, Packard was not a major engine designing company, and only has a few engines to its credit. One of these, the DR-980 was significant as it was a radial diesel, and flew in a Bellanca to set an endurance record of 84H 32min, which has not been beaten. Jesse Vincent of the company was one of the two people involved with the design of the Liberty engine (with E.J. Hall of Hall-Scott) and the company achieved great fame and success with the licence-produced Merlin engines of WWII, as the V1650, one of which holds the air speed record for a piston engined aircraft at 517.06 mph. The company produced engines for the Schneider Cup trophy competition in 1926, designated X-2775.
