Cars have a major impact on the environment and are a major contributor to air pollution, climate change and the depletion of natural resources like fossil fuels. The exhaust from automobiles emits toxins into the atmosphere that contaminate the water and air and cause harm to human beings. They also contribute to global warming by absorbing and trapping sunlight in the atmosphere which is known as greenhouse gases.

Modern automobiles have complex technical systems that consist of thousands of subsystems with specific design functions. Some of these are designed for off-road use and require rugged components with high resistance to severe overloads and extreme operating conditions. Others are designed for high speed and limited-access road systems that require passenger comfort options, optimized handling, engine performance and vehicle stability.

SUVs have raised seating and cargo carrying capacities that separate them from station wagons and sedans.
