In-Use Fuel Economy of 1981 Passenger Cars 820790

An owner survey was conducted to determine the owner-measured in-use fuel economy of 1981 model passenger cars. The in-use fuel economy has been compared to the Environmental Protection Agency's (EPA) fuel economy ratings. Data were analyzed to compare the influence of vehicle design parameters on the difference between in-use fuel economy and the EPA ratings. An analysis was also done to allow comparisons of in-use fuel economy from this survey with the results of a previously reported survey on 1980 models.
