Ecofly, the manufacturer of the Smart aircraft engine conversion, has started flight testing program of the new 80 hp Smart-Roadster engine. This engine was designed by Mercedes Benz and is used in the new Smart Roadster car. It is an upgraded M160 powerplant of the Smart citycar. Mercedes-Benz designed this 0.7 liter, 3 cylinder turbo motor to be light (132 pounds in car trim), compact, quiet and very efficient. The all aluminum engine has dual ignition and an intelligent turbo charging system that develops rated horsepower to over 8,000 feet and "overboosts" to develop additional power at low rpm. Cruise speed at a mild 4300 rpm is 111 mph burning less than 2.6 gallons/hour. Bosch fuel injection system eliminates carburetor icing and gives the engine great fuel efficiency. The Ecofly conversion of the engine incorporates a toothed belt reduction drive of 2.1 to 1 and includes a centrifugal clutch that engages the propeller at 1300 rpm. The package is very quiet, was rating only 54 dba during JAR certification testing. The installed weight is 11 pounds more then that of the 912s. See http://www.ecofly.de/english.htm
