Design and development The first known six-cylinder aircraft engine produced by Argus Motoren has been mentioned in the submissions to the Kaiserpreis contest for aviation engines which was held in 1912/13. The list of submissions states the engine having a nominal rating of , with a bore of and a stroke of . In the contest it developed at 1,370 rpm while weighing . The general design of the engine was carried over from the preceding four-cylinder Argus engines, particularly the Argus engine, with which it shared the same cylinder dimensions: the engine cylinders were of cast iron, cast in pairs of two cylinders, with the cooling jackets integral in the casting.
