Purchasers of expensive new electric vehicles (EVs) or hybrid vehicles (HVs) seem likely to use them as intensively as possible, not merely as second cars. This paper investigates intensive-use strategies for such vehicles at private households by means of a digital simulation using the travel day data from the 1977 Nationwide Personal Transportation Study. A “car-of-choice” usage strategy, in which the next home-based trip at a multi-car household takes the electric or hybrid car whenever it is available and has adequate seating capacity and range, leads to almost as much EV/HV use and travel electrification as the absolute maximum possible with perfect planning. Under this simple strategy, a single EV with four seats and a 100-mile range at each multi-car household would electrify almost 60 percent of all vehicle miles of travel by multi-car households. Average EV travel would then be some 20 percent above the average for all personal vehicles. A range-extension hybrid could electrify an equal amount of travel with a useful electric range of only 60 miles.
