The gasoline engine in the car burns gasoline. This chemical reaction produces energy which is converted to mechanical energy and drives the car down the street.
More precisely, the gasoline burns very rapidly in the cylinders and produces gas which expands and forces the pistons to move. The movement of the pistons in the cylinders causes the crack shaft to turn due to the cranking action of the crank case. The turning of the crank shaft turns the wheels by means of a linkage of gears.
The car's gravitational potential energy.
Potential energy is stored in the gasoline, the energy is then converted to heat, then to the kinetic energy of the car.

Assuming it just rolls down a slope, without the engines working: gravitational potential energy will be converted to kinetic energy. The kinetic energy will eventually be converted to heat energy.
