500 ‒ Series

  • What do you say about an engine family that ranges in power from 250 hp all the way to 350 hp? Innovative? Versatile? Amazing? How about all of the above? Continental® introduced the first 520 series engine to the world in the Beechcraft®  Bonanza and the Cessna® Centurion in 1964. The 520 series includes 520 cubic-inch models in either naturally aspirated or turbocharged configurations. The 550 series included 550 cubic-inch models in either naturally aspirated or turbocharged configurations. There are FADEC models available in the 550 series. With the right combination of thrust and efficiency, our 520 and 550-series engines have powered some of the most successful aircraft in general aviation history. 

    Continental Motors 500 Series Engine

    The 500 Series is a family of 6-cylinder, air-cooled, horizontally opposed, direct-drive aircraft engines with hydraulic lifters, 2 pushrod-actuated valves per cylinder, wet oil sump and fuel injection with manual mixture control or FADEC control.
