Has anybody looked at...
Developing a low revving but very high torque fuel efficient gas or diesel engine that feeds a generator that produces electrical power to batteries (or directly to) an electric motor-driven vehicle? The low revving engine would be computer controlled to maintain a minimum safe battery charge (but always running), thus the revving is computer monitored to smooth out and slow the acceleration and deceleration curves for maximum fuel consumption. The batteries allow for the instantaneous electrical power draw for short periods of large power drain (hard electrical motor acceleration). The high torque would allow for high ratios between the fueled engine and the generator output. The engine would not need fast acceleration as todays engines require due to the batteries covering for the brief electrical power demand and thus the engines can increase (or decrease) the revving at a very slow efficient pace.
