1990 GM HX3 Hybrid Van

Designed as a low-emissions, high-fuel-economy alternative to the traditional family sedan, the HX3 utilizes a powertrain that can be switched between gasoline or electric power. The monocab design seats five passengers comfortably in a compact package, and redefines the look and function of a traditional passenger car. Inspired by jet aircraft, the vehicle’s tapered shape achieves a 0.258 drag co-efficient.
