Rotax to begin 915 iS deliveries in 2017Rotax to begin 915 iS deliveries in 2017

Rotax is on track to certify and begin deliveries of its 915 iS engine in 2017, the company said.

The four-cylinder, 135-horsepower, turbocharged engine is designed to run on auto gas or aviation fuel and produce full rated power at altitudes up to 15,000 feet msl. It’s expected eventually to have a 2,000-hour time between overhauls.

“We’ve got pretty good experience with these engines,” said Marc Becker, head of aviation engines for Rotax, whose four-cylinder models have logged more than 50 million flight hours. “We think we know what we’re doing.”

Rotax engines are used on scores of aircraft models, most of them in the light sport category. The iS models are fuel injected, highly computerized, and extremely fuel efficient.

The Austrian firm is famously tight-lipped about future plans, projections, and prices. All that Becker would say about 915 iS pricing is that it is likely to be in line with the 100-hp 912 iS model upon which it is based.

“Pricing will follow the price logic of our other four-stroke engines,” he said.
