What do you say about an engine family that ranges in power from 285 hp all the way to 375 hp? Innovative? Versatile? Amazing? How about all of the above? Continental Motors introduced the first 500 series engine to the world in the Beech Bonanza and the Cessna Centurion in 1964. The 500 series includes both 520 and 550 cubic-inch models in either naturally aspirated or turbocharged configurations. There is even a geared variant that exceeds horsepower-to-displacement standards - a stunning 375 hp from 520 cubic inches. With the right combination of thrust and efficiency, our 500-series engines have powered some of the most successful aircraft in general aviation history.
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 or carburetor with manual mixture control. Geared, turbocharged, liquid-cooled or FADEC models are available.
