Abstract: Traction and dynamic, fuel and economic calculation of the vehicle is an important and integral part of a complex approach to vehicle design. According to the results of traction calculation, the main dynamic parameters of the vehicle are determined, the assessment of dynamic qualities is given by comparing them with similar indicators of other existing construction. During the traction calculation, such important parameters as the maximum power of the internal combustion engine, the gear ratios of the transmission elements, etc. are determined. There are two main methods for traction and dynamic calculation. The first method is a design traction calculation. It is performed when designing a new vehicle. The second method is a test traction calculation, which is performed for an existing vehicle. The test calculation is performed during the diploma. It is related with the selection of the base vehicle for a specialized vehicle or tractor for a road train. The purpose of this work is to help students determine the main dynamic and economic parameters of the vehicle and engine when changing the load and speed modes of its operation; dynamic performance during acceleration, to calculate the fuel efficiency of the vehicle. The proposed method of calculation will help to form students' knowledge, skills and abilities to analyze and select the parameters of the vehicle, which ensure the implementation of the specified indicators of its performance properties. The goal is achieved as a result of calculations and plotting of detailed tractionand speed characteristics of the vehicle, which characterize its consumer properties, followed by analysis of the parameters of vehicles. The peculiarity of this publication is to provide examples of determining the parameters of dynamic, fuel and economic characteristics of the vehicle, which allow to implement the concept of individual approach in the learning process. In the methodological instructive regulations the technique of check tractioncalculation on an example of the car Opel Astra Classic is resulted.
