The results of the Environmental Protection Agencies' analysis of fuel economy data from more than 4,000 cars tested on the Federal Driving Cycle are presented. Vehicle weight is the single most important vehicle design parameter affecting fuel economy. Other aspects of vehicle design include size, tires, axle ratio, engine compression ratio, air conditioning, transmission, emission controls, and engine size and type. Also important operational factors such as speed, trip length, acceleration, maintenance, road surface, grade and elevation. Alternative engines are also discussed.
