The aim is to develop a methodology for determining analytically the fuel consumption in a hot climate and substantiate
reliability, as well as the possibility of its application by comparison with test results. The article proposes
analytical methods for calculating fuel economy and traction-speed properties when modeling the movement of
cargo-carrying vehicles on real routes, based on theoretical and experimental studies in a hot and dry climate, which
allows for determining the efficiency of cargo-carrying vehicles objectively in terms of traction and speed, fuel and
economic indicators. Using the statistical processing of experimental, theoretical research data, the authors calculate
the coefficient X2, which allows for evaluating the adequacy of the mathematical model and experimental data. The
paper provides for an assessment of fuel economy and traction and speed properties. The authors presented the
results in graphs for the ease of evaluating the effect of external temperature on fuel consumption and the average
speed of a road train. The authors’ methodology allows for determining the efficiency of cargo-carrying vehicles in a
hot and dry climate.
