The new rotor was a nice idea from a marketing perspective, but its autorotational characteristics are lousy.
Aside from the single-pilot VFR cockpit (with 4-axis DAFCS, EFIS, FMS, 3D synthetic vision, EVS, TAWS, RMS and Euronav DMAP, all NVG-compatible) and the fixed gear, the aircraft also has a composite rear fuselage (which, together with the simplified gear, is said to reduce OEW by 220 lbs) and a 20-second 990 shp max power rating.
Aerodynamic tweaks to the rotor were also mentioned at one stage, but never detailed.
