---HondaJet's patented over-the-wing engine-mount configuration helps eliminate the need for a structure to mount the engines to the rear fuselage and, thus, maximizes the space in the fuselage. Further, by determining the optimal position for the engines, the over-the-wing mount actually reduces drag at high speed to improve fuel efficiency. ---
The engine mounts caught my eye. No doubt it makes the craft quieter, too.
