Environmental issues, aimed at reducing the environmental pollution have an increasing weight in society. Following the European Union's efforts in achieving a climate independent economy, a model comparing the energy consumption of different vehicle types will be presented. Many different models can be found in literature, differing in depth and level of transparency of the energy consumption while driving. In this work, we have developed a vehicle-type related model and used engine model based on characteristic maps. The objective of this work is to make a simple but sufficiently accurate model that records fuel consumption on a defined driving cycle. We have decided to develop a program with Python programming language. With the developed model two bus-type vehicle models were compared, namely an electric vehicle and a conventional vehicle with an internal combustion engine. The results indicate that the vehicle, powered by the electric motor, consumed less energy on all three comparison cycles than the vehicle, powered by the internal combustion engine.
