Generally, the hybrid cars are designed in such a way that they have two different engines- a gasoline engine to start and stop the car and an electrical engine to actually move the car. When two such engines are used, the car need not necessarily depend wholly on gasoline, which in turn brings down the cost of the gasoline being used.

Hybrid cars can also be categorized based on their modes of operation as series hybrid cars and parallel hybrid cars. In the former type, the gasoline engine starts the car and then the electrical engine takes over control of the car. The gas engine is also responsible for charging the batteries.

In the latter type of parallel hybrid cars, both the gas and electric engines are used to start and stop the car and also to enhance the power of the vehicle whenever needed and parallel hybrid cars are more fuel efficient than their series counterparts.

It is widely claimed that hybrid cars increase the efficiency of the fuel. This is justified by the fact that hybrid cars are made up of light weight materials. Therefore, the load on the hybrid car is brought down to a great extent and hence it does not need more fuel to move. The size of the engine of a hybrid car is less than that of other cars. In addition, the tires of the hybrid cars are firmer than those of regular cars.

Evidently, hybrid cars emit lower amounts of carbon di oxide into the atmosphere, reducing the green house emissions as much as fifty percent. One more advantage of a hybrid car is that it has a self charging feature and so, there is no need to plug into an outlet which is very convenient while going on a long journey. The battery is recharged while it is running slow or not in motion.

In conclusion, it can be authentically stated that hybrid cars are more economical than other vehicles because they consume only fifty to sixty percent less fuel and are undoubtedly environment friendly. But the high cost of the hybrid car is a drawback but that can be overcome if more and more environment-conscious people come forward to purchase hybrid cars, due to the obvious benefits. Hybrid cars offer a good chance for every car user to contribute his part in saving the greenery of the earth and make it a better place to live in!
