The fuselage is a compact and lightweight unified carbon composite structure, and has the largest cabin in its class. The main wing, which features aluminum skin panels cut from single sheets of aluminium that provide a smoother surface than conventional wing configurations, along with Honda's proprietary turbulence-reducing laminar airfoil, work together to significantly improve aerodynamic performance. Additional drag-reducing technologies include the fuselage nose, which is designed to generate laminar flow. These features, in combination with Honda's fuel-efficient HF118 Turbofan Engine, provide fuel efficiency more than 40% better than conventional aircraft.
