At AirVenture Oshkosh 2015, Rotax Aircraft Engines made a special announcement … that of their new 135 horsepower 915 engine. The new powerplant, due out on the market in the last half of 2017, features characteristics of the 912 iS Sport with its fuel injection and the 914 Turbo. However, the 915 with its more powerful turbocharger now also incorporates an intercooler. It weighs a bit more and will cost somewhat more, but can sustain a continuous 127 horsepower. In all, this is an engine many airframe producers will greatly anticipate.
