Performance and costs are projected for future hybrid-electric cars in which a small internal-combustion engine (ICE) is added to the basic electric propulsion system to permit unlimited highway range. In most driving these hybrids would be operated in the all-electric mode without use of the ICE, thus providing most of the benefits of electric cars without their range limitation. The curb weight, range on batteries, energy requirements, and life-cycle costs of such hybrids are projected as a function of battery weight for four-passenger, subcompact hybrid cars using improved and advanced technology including future lead-acid, nickel-zinc, and lithium-sulfur batteries. A desirable configuration using either lead-acid or nickel-zinc batteries would weigh about 1500 kg, travel about 125 km on batteries alone, cost about ten cents per kilometer overall, and require ICE use in typical applications for roughly 15% of total travel.
