A study was made to provide a projection of the characteristics of future passenger highway vehicles through the year 2000. The vehicles considered are all extensions of present heat engine technology, and storage systems or hybrid power were not included. Data are given on the change in fuel economy, incremental change in consumer cost, and total vehicle weight by vehicle size for each of the time periods. The most likely technical improvements and the timing for their introduction are indicated. Substantial fuel economy gains have been made since 1974 and further substantial gains will be made for all makes of vehicles through the year 2000. These gains are possible with relatively low technical risk until the years 1990-2000. Gains made during the 1990-2000 period will result through engineering development rather than through different and alternative heat engines. This effort will be addressed to optimizing combustion and mechanical equipment technology. Alternative engines will only become practical production units in the 1990-2000 period and only if there is a marked advantage over current heat engines, to save traditional petroleum base fuels.
