When Rotax moved their 912 iS Sport project from engineering to production, the big Austrian engine manufacturer elevated their already-immensely-popular 9-series engines to a higher level. Beside fuel injection, the company added electronic engine controls more advanced than any other in their inventory. If you’ve flown with the iS Sport as I have you know it has terrific performance — torque was increased through an enlarged airbox along with other minor refinements — plus it gives even better fuel consumption. When flying with Aerosports‘ Jeremy Knoll at DeLand 2017, I heard that his trip from Wisconsin to Florida in the TAF Sling yielded fuel consumption rates of 2.7 gallons per hour at cruise. Man! That is some fuel efficient flying and that is part of what Rotax achieved with their iS model. They will use that technology plus more on their coming 135-horsepower 915 iS due on the market next year.
