Diesel cars are becoming extinct now. Which one to opt out of Petrol, Electric and Hybrid Cars?

Blog Posted on:-November 18, 2019 Categories:- Technical , News

As all of you must be aware of the fact that the whole world is struggling with climate change and trying for various options to save the future for our next generations. One of the most promising options is to cut pollution created by the exhaust emission coming out of the vehicles running on roads. Passenger vehicles are facing fear of planned ban from government in the future. It’s not likely to happen over a decade. But, one must take it into a serious consideration. It is highly likely that cars driven by fossil fuel (specially diesel) will get disappeared in a period of two decades.

What are the alternatives?

All the cars on the road need to be replaced with the ones having lower or zero emission. Petrol cars are considered to be less pollutants as compared to diesel cars. So, it is possible to keep the petrol cars on the road for some more time after banning diesel cars. Ultimately, electric or hybrid cars seems to be the only life saver at the moment. If you are planning to invest some money in purchasing a new or used dream car, you must consider these options also. But, first, you must understand the differences among petrol, electric or hybrid cars in India.

What is petrol car?

Internal combustion engines (ICE) were discovered to convert chemical energy from the fossil fuels to the mechanical energy into the wheels in a car. It was a great invention, still it is, indeed. Isn’t it? Engines in the petrol cars have two drawbacks. First, it requires petrol (off course) which is limited product available on the earth and is becoming costlier day by day. Second, it produces more pollution which, in turn, helping in expansion of the climate change. Time has come to discourage this type of conventional car engines by replacing with modern engines.

What is electric car?

Electric car, in fact, is the simpler engine technology for understanding of a layman. It just requires a battery, charger and an electric motor to power the wheels in the car. However, manufacturing of these cars requires high level of technology which is still under development. A lot of research is going on to make charging and discharging of the batteries highly safe and efficient. Battery has become one of the most favourite topics for the research in top universities of the world. Presently, Li-ion battery is found to be most stable for electric cars. Companies related to electric cars (e.g. TESLA, BMW, TOYOTA etc.) are not only developing improvements in Li-ion batteries but also, working on to develop batteries using completely new technology to overcome the drawbacks in it. We will stop discussing the batteries more here, otherwise this will become separate blog post.

Once you have owned an electric car, you can charge it at your home for overnight or at charging stations provided by the manufacturer of the car. Most famous manufacturer of the electric cars in the world in known as TESLA. Model 3 is most admired electric car, which changed the perception of the people by removing the fear of owing a useless car as compared to convention gasoline powered car engines.

What is Hybrid cars?

Always, hybrid cars have been very confusing for most of us. What we know is that it is basically a combination of an electric car and conventions petrol car. Certainly, it is. But, there are variations in hybrid cars depending upon how it couples both these powers sources. So, first, let’s understand what it is. There are mainly three types of the hybrid cars.

a) Hybrid Cars

In a normal hybrid car, petrol engine is supposed to charge the batteries which, in turn, powers the wheels ultimately. So, this way, car is supposed to be more efficient in burning the convention fuel and thus returning cheap running cost and less environmental cost. This type is not much appreciated as the impact of increasing the cost by adding batteries and charges etc. is not justified.

b) Plug-in Hybrid Vehicles (PHEV)

Practically, this can be understood as a car which carries both petrol engine and electric engine simultaneously. In this car, you can get petrol in petrol tank and drive just as in conventional cars, also, you can go to a charging station and plug-in the charger and have fun as in electric cars. Some of the most popular PHEVs are Toyota Prius, Mitsubishi Outlander PHEV, and the sporty BMW i8. These cars are still not available for sale in India.

c) Mild Hybrid

This type of hybrid car is such a combination of electric and petrol engine that petrol is mostly used to power the wheels and battery power is used occasionally in case when demand of power is low. Also, battery can be charged using regenerative braking which ultimately helps in improving the fuel efficiency as well as exhaust emission. Most common type of existing hybrid cars available in India are mild hybrid cars. There are several manufacturers like Tata, Mahindra, Maruti who are producing mild hybrid cars. My favourite one is Maruti CIAZ hybrid.


Hope, I have brought out some clarification of doubt regarding electric cars and hybrid cars in your mind. All of these options available to you carry some advantages and disadvantages. A car which is suitable to you may not be the best option for others. So, you need to be very specific about your requirement. But, one must consider an option of buying electric or hybrid cars. Presently, electric cars may not be looking to be obvious purchase, but, future lies in electric cars only.
