BRP has announced a more powerful, 135 horsepower Rotax aircraft engine at the Experimental Aircraft Association’s July AirVenture fly-in at Oshkosh, Wisconsin; the Rotax 915 iS.

Based on the proven concept of the Rotax 912/914 engine series, the 915 iS engine offers what its manufacturer is saying is the best power-to-weight ratio in its class, maintaining full takeoff power up to at least 15,000 feet and having an operating ceiling of 23,000 feet.

“The more powerful engine was specifically requested by our customers,” said Thomas Uhr, vice president BRP-Powertrain and general manager BRP-Powertrain GmbH & Co KG. “It opens the way for larger, heavier aircraft, larger autogyros and even small helicopters — or simply more performance for current applications.”

The 915 iS is a four-stroke, four-cylinder turbocharged aircraft engine with intercooler and a ‘redundant’ (i.e. duplex) fuel injection system. Rotax claims that it delivers the most advanced aircraft engine technology, resulting in low operating cost and ease of use. Production is scheduled for the second half of 2017.
