The U.S. Market for cars using stored, externally generated energy rather than stored fuel will depend largely upon the intended vehicle use. For short-range, multi-stop commercial applications over defined routes, electric vehicles may produce attractive life-cycle cost savings for fleet owners. By contrast, a sizeable penetration of the personal market for this type of car will probably await the development of vehicle characteristics, including first cost, that are competitive with those of gasoline-powered cars. The committee concluded that a competitive, electric, family vehicle capable of carrying four to six passengers and having a 200-mile range, 55-mph speed, and a competitive first cost will require at least 25 yr. of R&D. Batteries weighing no more than about 25 percent of the gross vehicle weight will be necessary for competitive performance of family cars. First-cost comparability will require that these advanced batteries have a specific energy cost considerably lower than that of the millions of automobile batteries now made each year. A vehicle combining storage with a conventional gasoline engine might achieve earlier market acceptance. For example, a flywheel, coupled with a small engine, might preserve the range and flexibility of the gasoline-powered vehicle while markedly improving mileage and reducing emissions. Such flywheel concepts need further development of establish their performance, safety; and cost characteristics.
