Structure
The structure of a hybrid car is almost identical to that of an ordinary gas or diesel powered automobile. Components:
 * Gasoline engine
 * Fuel tank
 * Electric motor
 * Generator
 * Batteries
 * Transmission

__Engine__ Hybrid automobiles use a regular combustion engine, however the engine in a hybrid is smaller and uses advanced technologies to reduce emissions and to increase efficiency at the same time. The displacement of the cylinders is bigger, which requires more fuel for each cylinder to move in a regular vehicle. Even while the car is idling, each cylinder uses fuel every time the engine fires. "Pistons and other internal components are heavier, requiring more energy each time they go up and down in the cylinder" (Nice and Layton).

__Electric Motor__ Along with a smaller combustion engine, a hybrid is equipped with an electric motor which is "very sophisticated" (Nice and Layton). Advanced electronics allow it to act as a motor as well as a generator, and if the hybrid car needs too, it can draw its energy to accelerate the car. Acting as a generator when slowed down, which in return, takes energy back to the batteries of the hybrid.

__Batteries__ The electric motor in the hybrid cars and the batteries go hand and hand. In hybrid cars, batteries are the energy storage device for the electric motor. Unlike the typical gas tank, an electric motor can take from the batteries and give back energy to the batteries as well (Nice and Layton). The car usually sends back the most energy to the batteries when the car is coming to a stop. But if the hybrid abruptly stops the generator in the car does not get a chance to recover some of the energy while slowing down, become less efficient. []
