Chornedsnorkack basically made the point.... While the CS100 makes 2200 nm of range in the standard version (up to 2950 for the ER) the E195 requires it to be the AR version (Advanced Range) to range 2200 nm...
For fuel burn they currently advertise IIRC around 16% less than the E195, as they show on the "animated" mockup at airshows.
For other data, they are still unknown (like the Basic Empty Weight).
Re-reading the statements and the above mentioned list.... I actually think that we'll see the KLM livery on the CS100....
Each evening, stars come out their daylight hiding places... But one of those, is my wingtip, passing over...
