Due to the decreasing supply of fossil fuels and the increasing demand for oil, auto manufacturers are developing cars that use other sources of energy, such as electricity and hydrogen. Called hybrids, these cars combine two or more sources of power that can directly or indirectly generate propulsion power.
Most hybrids today combine combustible gas engines and electric motors, which maximize performance, reduce fuel consumption, and emit far less carbon than gasoline-fueled vehicles.
Hybrid cars are often confused with electric cars. Hybrid cars are generally gasoline-burning machines that use electric parts to store and reuse energy that usually goes to waste in conventional cars. Theoretically, diesel-electric hybrid vehicles should be even more fuel-efficient, but diesel engines and hybrid systems can be very expensive.
There are many different models of hybrid cars today, but what they have in common is the ability to produce electricity, store it in a large battery and use it to help power the car. Hybrid vehicles come with a regenerative braking system that generates electric power to help keep their batteries charged.
When you apply the brakes, the electric motor immediately generates electricity, and the magnetic drag slows down the car. There’s also a conventional hydraulic braking system that stops the car in case the regenerative braking is not enough.
Car manufacturers use a variety of hybrid drivetrain technologies in their hybrid cars.
If you take a lot of long-distance trips, a diesel car will suit you better. If you do most of your driving in town, however, a hybrid car is worth considering. Just keep in mind that hybrid cars are more expensive than non-hybrids, and the money you save on fuel may not be enough to offset the higher purchase price.
