Title: Motor vehicle MPG and market shares report: model year 1984

Abstract

This issue of the publication reports the sales, market shares, estimated sales-weighted fuel economies, and other estimated sales-weighted vehicle characteristics of automobiles and light trucks for the model year 1984 and for the previous five model years. Comparisons and observations are made on the trends in these vehicles from one model year to the next. An improved methodology is used to allocate the yearly MPG changes among eight components, rather than the four reported in the previous reports. Sales of automobiles showed an increase of 16.6% from model year 1983. An even more striking increase was observed in the sales of light trucks: 30.5% from model year 1983. The 1984 model year experienced a gain of 0.23 mpg in sales-weighted automobile fuel economy. In contrast, light trucks experienced a loss of 0.59 mpg in fuel economy, from 20.50 mpg in model year 1983 to 19.91 mpg in model year 1984.

  • This issue of the publication reports the sales, market shares, estimated sales-weighted fuel economies, and other estimated sales-weighted vehicle characteristics of automobiles and light trucks for the first six months of model year 1984 and for the previous five model years. Comparisons and observations are made on the trends in these vehicles from one model year to the next. An improved methodology is used to allocate the yearly mpg changes among eight components, rather than the four reported in the previous reports. Sales of automobiles showed an increase of 21.8% from the first half of model year 1983. An evenmore » more striking increase was observed in the sales of light trucks: 42.2% from the first half of model year 1983. The first six months of model year 1984 experienced a gain of 0.21 mpg in sales-weighted automobile fuel economy. In contrast, light trucks experienced a loss of 0.83 mpg in fuel economy, from 20.52 mpg in model year 1983 to 19.69 mpg in the first half of model year 1984.« less
  • Estimates of final model year 1983 new car and new light truck MPG are provided. ORNL has modified the procedure for calculating new car MPG. The new procedure takes into account the sales mix of engine size, engine type (gasoline or diesel), and transmission type within a nameplate (car line). For example, the new ORNL method takes into account that over 60 percent of the Chevettes in 1983 were the gasoline version (98 CID engine displacement) with a 3-speed automatic transmission. Also, the three diesel model types accounted for only about 1 percent of the Chevette sales. This new methodmore » estimated the Chevette MPG for 1983 to be 33.2, nearly 5 MPG lower than the estimate based on the old method. Since this report contains revised new car MPG estimates for every year, the fuel economy estimates in this report are not comparable to those in any previous ORNL report. The estimates of new light truck MPG have not been revised, however.« less
  • This issue reports the estimated sales-weighted fuel economies, sales, market shares, and other estimated sales-weighted vehicle characteristics of automobiles and light trucks for model year 1978 through 1986. Monthly vehicle sales data are used as weighting factors in the sales-weighted estimation procedure, enabling the estimates to reflect averages for the overall new vehicle fleet. Comparisons and observations are highlighted on the trends in these vehicle characteristics from one model year to the next. Analyses are carried out on the fuel economy changes to determine the factors that have caused the changes.
  • This issue of the publication reports the sales, market shares, estimated sales-weighted fuel economies, and other estimated sales-weighted vehicle characteristics of automobiles and light trucks for the first six months of model year 1985 and for the previous seven model years. Comparisons and observations are made on the trends in these vehicles from one model year to the next. A methodology is used to allocate the yearly mpg changes among eight components. Sales of automobiles showed an increase of 2.4% from the first half of model year 1984. An even more striking increase was observed in the sales of lightmore » trucks: 18.7% from the first half of model year 1984. Light trucks continued to claim a larger share of the entire light-duty vehicle market. Approximately 30% of the vehicles sold in the first six months of model year 1985 were light trucks. The first six months of 1985 model year experienced a gain of 0.60 mpg in sales-weighted automobile fuel economy. Light trucks also experienced a gain of 0.40 mpg in fuel economy from the previous model year.« less
  • Sales of automobiles jumped dramatically from 10,211,058 units in model year 1984 to 10,968,515 units in model year 1985, an incease of 7.4%. Light trucks had an even more striking increase in sales, rising 17.2% from the previous model year. The sales-weighted fuel economy for the entire automobile fleet continued to climb in model year 1985, from 26.3 mpg in model year 1984 to 27.0 mpg in this model year. The sales-weighted fuel economies in light trucks have remained relatively constant since model year 1979. The trends of various vehicle characteristics from model year 1978 through 1985 are illustrated. 34more » figs., 45 tabs.« less
