A problem of comparing the traction properties of Daewoo Lublin 3 Mi van with respective types of gearbox has been taken up in the paper. There were three gearbox types: TS5-21, PD.97 and ZF. These properties were concluded based on vehicle traction graph. They included: reaching the reserve driving force in respective gears, obtaining accelerations, overcoming the resistances to motion (rolling resistance, air resistance and grade resistance) as well as achieving the maximum speed. Vehicle traction diagram has been made based on the torque curve of Andoria 4CTi90 engine external characteristics obtained on engine test bed in a direct way using an AVL eddy current brake. The engine was supplied with a complete fuel dose and loaded with the resistance torque produced by engine brake. The characteristics was performed every 200 rpm from 1000 rpm to maximum revolutions and the other way from maximum revolutions to 1000 rpm every 200 rpm. The torque characteristics points were determined as a mean value obtained from these two measurements. After considering the data from engine external characteristics, vehicle information (including, among others, respective gear ratios and final drive ratio, under-the-bonnet power loss coefficient, and dynamic wheel radius) and the resistances to motion, a vehicle traction diagram of Daewoo Lublin 3 Mi van was made for three types of gearboxes. Based on this, the authors found that a Daewoo Lublin 3 Mi van equipped with ZF gearbox is the best from the point of view of traction properties.
