Pratt & Whitney’s new PurePower Geared Turbofan aircraft engines are impressive beasts. Scheduled to enter commercial service before the end of the year, they burn 16 percent less fuel than today’s best jet engines, Pratt says. They pollute less. They have fewer parts, which increases reliability. And they create up to 75 percent less noise on the ground, enabling carriers to pay lower noise fees and travel over some residential areas that are no-fly zones for regular planes. Airbus, Bombardier, Embraer, Irkut, and Mitsubishi have certified the engines for use on their narrowbody craft. JetBlue, Lufthansa, Air New Zealand, Malaysia’s Flymojo, and Japan Airlines are among the engine’s 70 buyers in more than 30 countries.

Sounds like sales talk to me.
As long as they didn´t get Volkswagen to provide the engine management software.

Nice concept, I wonder if the benefits are better than the "$10 billion?"

16 percent better than today's best engines? That is a gigantic difference. Impressive if true, but what's the catch .. 16% less powerful than today's best engines (note that they don't mention power anywhere in the inforgraphic -- i didn't read tthe article :P )?
