BRP Rotax has launched a new engine, the Rotax 912 iS, as an evolution of its popular four-cylinder, four-stroke line for the light-sport market. Designed to burn less gas without sacrificing performance or reliability, the engine is claimed to be as much as 70 percent more fuel-efficient than competing engines.
The biggest improvements in the new engine come from the replacement of the 912’s carburetor with a modern fuel injection system and digital engine control unit (ECU). The engine produces 100 hp while also boasting a 2,000-hour TBO, the same as the 912 engine. Mass production of Rotax 912 iS engines will start in May.

"The development of a four-stroke, four-cylinder 100 hp aircraft engine with a redundant electronic fuel injection system is a first in the industry,” said Gerd Ohrnberger, vice-president and general manager at Rotax’s Powertrain division. “It makes it ideal for all kinds of light sport aircraft.”

I don't think any other engine company has a proven 2000 hr TBO certified in aircraft.

Any idea on the Price?

The Ulpower 350(130hp) Is has fuel injection and dual ECU.  Maybe Rotax is deeing the competition from UL and the Viking and others to come. It's all good for the consumer...competition usually drive prices down.
