The purpose of this analysis has been to evaluate and quantify the differences between EPA test-measured and actual on-road fuel economy. It is expected that the methodology and the adjustment factors developed in this analysis will form the basis for a labeling system that, in future model years, will discount the EPA test measurements of new cars to estimate on-road fuel economy. Because new cars employ a growing percentage of fuel efficient technologies having distinctly lower levels of shortfall than traditional ones, this analysis has carefully evaluated and, to the extent that available data permit, quantified the shortfall of the alternative technologies.
