The U.S. Department of Transportation has established fuel-consumption standards for passenger vehicles and light trucks that will result in increasingly fuel-efficient vehicles in the future. Projections of characteristics of the mix of vehicles on the road that can be expected to change as a result of industry compliance with the standards are presented through 1995, based on a variety of government and industry publications. The average mass (weight), power, and engine size of passenger vehicles--including light trucks with a maximum gross vehicle weight of 3860 kg (8500 lb)--will obviously decrease during this period. Fuel economy will continue to improve steadily, and average acceleration performance will not decline appreciably after the 1983-1985 period. The characteristics of recreational vehicles will change, mostly in the next few years. All of these changes in on-the-highway averages will be brought about through "replacement" of heavy and high-performance vehicles by others of more modest weights and powers rather than through the introduction of very small or low-performance vehicles, which will lead to a more homogeneous vehicle population.
