Car Technology
In order for a car to work, it must have fuel. The most common fuel is petrol, which is called gasoline in America. Some cars burn diesel or ethanol. A few can run on several different fuels. Alternative fuel vehicles use less common fuels like natural gas, wood gas or electricity. In some countries, such as Brazil and Sweden, a mixture of ethanol and petrol, called 'gasohol' in Brazil and 'E-85' in Sweden, is used as automobile fuel.
