A three-wheel vehicle apparatus has one front wheel and two rear wheels to improve safety of operation, including a novel tilt-and-bank mechanism, front wheel suspension, safety frame, aerodynamic body design, and sliding doors. The tilt-and-band mechanism employs a tilt bar connected to hydraulic cylinders and spring/shock units mounted on the wheels which automatically tilt and bank the vehicle in turns. The front wheel suspension mounts the front wheel on a trailing arm and uses a reaction arm connected to a pivot pin in front of the wheel for better handling of centrifugal forces in turning. The safety frame employs three crosswise roll bars connected together by three longitudinal bars and connectors, all in turn connected to a complete wraparound bumper. This vehicle is made aerodynamically more efficient by a pointed nose and a new upswept tail that eliminates rear drag at high speeds. Additionally, doors which can be opened and remain open at high speeds are roller mounted on the outside of the passenger compartments. The improved vehicle is designed to make the use of three-wheel vehicles on today's highways safe and reliable.
