They are claiming improvements across almost all areas. If it flew as fast and as far as the competition on 50% less fuel, that would be amazing. If it flew 60 knots faster in the same fuel and payload, awesome! However, they are claiming improvements across the board. 3x the range, significantly faster, flies higher, uses less fuel. It doesn't pass a sniff test. Compare it to the Grob Strato 2c. Notice how long the wings are by comparison? This is a feature of nearly all subsonic high altitude aircraft. Also notice the how long the props are on the Grob, another feature of high altitude aircraft conspicuously missing on this aircraft. Pusher aircraft are not new. In fact they are as old as powered aviation itself. They generally aren't significantly more efficient. https://en.m.wikipedia.org/wiki/Grob_Strato_2C https://en.m.wikipedia.org/wiki/Grob_Strato_2C
