Question

The form of energy needed to run a car

Answer 1

the answer is kinetic energy
because as we need to run a car the energy should be strong so kinetic energy has its particles charge up already

Answer 2

The potential energy of the fuel is converted into the thermal energy due to internal combustion which is then transformed into the mechanical energy that further helps in accelerating the car thereby increasing the kinetic energy.

These were the useful energy transfer or conversion that helps the car to start and move further.
