Answer is chemical energy.

The fuel used in car is petroleum product which is a fossil fuel. Petroleum products such as petrol or diesel are chemical compounds in which chemical energy is stored in their bonds. When these compounds undergo chemical reactions, resulting in breaking of bonds and releasing energy. When ignition of a car is on, the energy is released when chemical bonds are broken.
