The aim of this study was to compare instantaneous fuel consumption of a FIAT Panda car with three types of propulsion system applied: engine positioned front-lengthwise to the direction of travel and rear-wheel drive, engine positioned front-transversely to the direction of travel and front - wheel drive and all-wheel drive. The vehicle was equipped with a 1.3 JTD MultiJet compression-ignition engine being used for conducting experimental tests. This part was based on making the load characteristics (relationship between specific fuel consumption and engine torque) using engine dynamometer. This was made for given parameters corresponding to specific traffic conditions. They were determined in a simulation and were represented by rolling resistance and air resistance. Their value was affected by vehicle technical and operating characteristics and its design features, such as maximum weight, transmission system ratios, dynamic wheel radius, drag coefficient, width and height, and efficiency of propulsion system. The efficiency of power train system was adopted from a simulation conducted for different types of propulsion system. Apart from basic resistance, additional drag (inertia resistance) was the most important in vehicle energy balance. It played an important role in determining the value of instantaneous fuel consumption for variable velocity and constant acceleration values used in the UDC test (Urban Driving Cycle – subtest of the EUDC cycle). The lowest fuel consumption for a given car velocity was for front-wheel drive transmission system, whereas the highest for allwheel drive system (4x4).
