The goal of this subject is to give the students an insight into effects vehicles have on the environment. Preservation of the environment and minimization of the negative impacts of driver-vehicle-environment system are the basis of modern vehicle development and exploitation. Therefore a more detailed analysis of these effects in this case are a prerequisite for creating a modern engineer, not only in the field of motor vehicles.

Upon successful completion of this course, students should be able to: - Explain the concept of fuel consumption and the possibilities for its reduction; - Analyze the impacts of driver on fuel consumption; - Identify and explain the harmful elements of the exhaust emissions of motor vehicles, ways of their formation and effects, methods of measurement and legal constrain values per component; - Identify alternative vehicle drives and fuels; - Analyze working principles of hybrid and electric vehicles; - Explain the impact of noise and vibration produced by vehicle; - Recognize environmentally friendly and modern materials used in the design and manufacture of vehicles; - Describe the recycling process and the life cycle of the vehicle.

Introductory classes relate to the importance of the vehicle in production, transportation and traffic in contemporary economic and social environment. They are followed by lectures that look back on the development of automotive technology that was largely affected by environmental conditions. The following lectures are divided into blocks according to a rough classification of basic elements of the impact of vehicles and drivers on the environment: 1. fuel consumption; 2. exhaust emission; 3. hybrid and electric vehicle drivetrain; 4. alternative fuels; 5. noise and vibration; 6. recycling and the use of modern materials. The final lectures are planned to present the future trends in the design and exploitation of vehicles with the aim of improving environmental protection.

During practical classes, students analyze the performance of various electric and hybrid vehicle drivetrain configurations in terms of energy consumption through computer simulation of different driving cycles, taking into account the impact of varyous vehicle parameters on energy consumption. Additionally, by solving tasks, students assess the influence of different factors on the energy consumption and exhaust emissions of electric vehicles and fuel cell vehicles. Furthermore, they perform drivetrain component sizing for the aforementioned vehicles. As part of the practical work, students also complete project assignments on the previously mentioned topics. In addition to all this, students participate in driving electric and hybrid vehicles under real-world conditions. Students are also required to write the essay on a given subject.
