How do hybrid cars save energy?

Hybrid cars save energy by combining an internal combustion engine (ICE) with an electric motor and a battery. The ICE is used to power the car at higher speeds and during acceleration, while the electric motor assists at lower speeds and during braking. The battery stores energy that is generated by the ICE and the electric motor. This energy can be used to power the electric motor or to provide additional power to the ICE.

There are two main types of hybrid cars: full hybrids and mild hybrids. Full hybrids have a larger battery and can travel longer distances on electric power only. Mild hybrids have a smaller battery and are less efficient, but they are also less expensive.

Hybrid cars save energy by:

* Using the electric motor to assist the ICE at lower speeds and during braking. This reduces the amount of fuel that is consumed by the ICE.

* Storing energy in the battery that is generated by the ICE and the electric motor. This energy can be used to power the electric motor or to provide additional power to the ICE.

* Using regenerative braking to generate electricity when the car slows down. This electricity is stored in the battery and can be used to power the electric motor or to provide additional power to the ICE.

Hybrid cars can save a significant amount of energy compared to conventional gasoline-powered cars. In fact, some hybrid cars can achieve fuel economy ratings of up to 50 miles per gallon (mpg) in city driving.
