A development program for three small, lead-acid battery powered cars is described. Designed for but one or two occupants, the gross weight of the cars range from 680 to 1150 lbs. (310 to 520 kg). During the systems engineering study phase two car types evolved: (1) an upright, comfortable, low-performance Leisure-Town car and (2) a low-slung, good acceleration, sport-commuter vehicle. Extensive structural optimization efforts, shape simplification and the elimination of nonessentials keep total weight low to minimize energy requirements. Drive train and control system efficiencies also receive much attention; various test data on energy conversion efficiencies are provided. Calculated data showing low energy cost per distance traveled is also provided. This is countered by data on first-cost and weight penalties, compared to gasoline engine energy. Finally, the safety implications of such small and light vehicles are discussed, and safety provisions in the designs are described.
