The Argus As 17 was an inverted six cylinder aircraft engine in the 200 horsepower (149 kW) class that was first demonstrated in 1934. It was a development of the company's As 8 four-cylinder engine.The engine had cast aluminium heads and aluminium pistons mounted in steel cylinders and connected to a chrome-nickel steel crankshaft. Bore was 120 millimetres  and stroke 130 mm

It was used to power a small number of German aircraft in the late 1930s, notably three entries to the Challenge International de Tourisme 1934, the Fieseler Fi 97, Klemm Kl 36 and Messerschmitt Bf 108. Each aircraft was entered in two variants, one powered by the Argus engine and other with the more powerful Hirth HM 8U V-8. The engine was developed in three versions. The lower powered As 17A, which was used to power the fourth prototype Bf 108, was rated at 200 hp. A more developed engine, the As 17B, rated at 220 hp (164 kW), was used to power the seventh Bf 108A prototype. The more powerful As 17 Special was also produced, which differed in having a supercharger that increased rated power to 280 hp (209 kW).

The engine was produced in small numbers, never achieving serial production. Only two of the Fieseler aircraft were fitted with the engine. Klemm preferred the Hm 8U for the definitive Kl 36B. Production examples of the Bf 108 used either the HM 8U or Argus's own V-8, the As 10, the latter becoming the standard for the BF 108B.
