Abstract
The EPA is presently conducting studies which are directed to identifying differences in fuel economy as measured on the FTP test and reported in the Mileage Guide compared to in-use vehicle measurement. One of these studies is directed to the identification of differences in the fuel economy performance of production vehicles relative to the counterpart certification vehicle. A brief study of the effects on emissions and fuel economy of variations in manual transmission shift points was conducted on one of these production vehicles. The results of this transmission shift point study are contained in this report. The conclusions from these tests can be considered to be quantitatively valid only for the specific type of vehicle used in the study, although it is reasonable to extrapolate the results to other types of vehicles in a directional or qualitative manner.
