A long range and safer, steerable vehicle body for carrying at least one passenger and which body rides on at least two wheels and is constructed from ultra-lightweight materials, such as magnesium frame with polyolefin body panels. The frame is constructed from extruded tubings, joined with aid of end fittings, adhesive and body-bound pins, which eliminates expensive welding. The body panels have double walls, or a honeycomb sandwich construction. The vehicle body may carry an advanced, non-polluting hybrid propulsion system and may ride on pressure-airless tires.
