In this thesis the most significant technologies that define a modern car will be described in detail. The first three chapters of this work will explain how things have changed in cars when it comes about power and fuel efficiency through the development of engines and lightweight materials. Further chapters will address safety features which are divided in active and passive features. It will be able to see that the biggest improvements are being made about active safety features such as vision technologies and stability and braking technologies. In the last part there will be a word about infotainment systems, comfort and practical usage of technologies in driving schools. Despite the fact that all mentioned inventions are important modern car technologies, there will be given slightly bigger importance to those features called safety features, especially the active safety features.
