Some of the main components of a hybrid car are listed below for your information:

Gasoline engine - The hybrid car has a gasoline engine similar to the one in traditional cars. However the engine size of the gas engine is considerably smaller than the engine in the traditional cars. The engine uses advance technologies which results in the increases fuel efficiency and reduced level of emissions.

Fuel tank - The fuel tank in a hybrid is the energy storage device for the gasoline engine. Due to the higher density of gasoline it takes about 1 kilo pounds of batteries to store the same amount of energy as would be stored from a 1 gallon if gasoline.

Electric motor - The electric motor on a hybrid car is very sophisticated. It acts as a motor and generator. It can draw energy from the battery and convert to accelerating energy for the car or as a generator by returning energy to be stored in the batteries.

Generator - The generator is similar to an electric motor, but it is used to produce electric energy. Mostly the series hybrid have a generator in their system.

Batteries - The batteries in a hybrid car are used to store the the energy generated from the electric motor. The electric motor as said before acts as a motor and generator, and it can either draw energy or supply energy to the batteries. The gasoline engine takes the gasoline from fuel tank to generate accelerating energy.

Transmission - The transmission on a hybrid car performs the same basic function as the transmission on a traditional car. Some hybrids, like the Honda Insight, have conventional transmissions. Others, like the Toyota Prius, have Electronically controlled continuously variable transmission (ECVT).

Tires: Hybrid cars use low resistance tires. The tire are usually inflated for a higher pressure.
