Which is more economical to own and run?

The decision between electric, diesel, and gasoline-powered vehicles has grown more difficult as newer models of electric vehicles (EVs) are introduced and the cost of fossil fuels like gasoline and diesel rises. The long-term economic feasibility of these cars should be evaluated by looking at a number of aspects, including mileage, government incentives, cost of purchase and maintenance. Here, we'll weigh the pros and downsides of having an electric vehicle over a petrol or diesel vehicle, compare the three possibilities, and decide which one is the most cost-effective


Petrol, diesel vs electric cars comparison : Initial Cost

Compared to diesel and electric vehicles, the cost of purchasing a petrol car is lower. In contrast to gasoline-powered vehicles, diesel vehicles are more costly initially, but electric vehicles are the most expensive. However, as technology develops, electric car costs are progressively coming down..

On-Road Price
Rs 8.75 Rs 11.40 Rs 15.25

Thus, the electric vehicle (EV) costs over Rs 4 lakh more than the diesel version and
Rs 6.50 lakh more than the petrol version


Petrol, diesel vs electric cars comparison : Maintenance Expenses

Diesel cars frequently require more maintenance than petrol cars, mostly because of the complexity of their engines and emission control systems.

As opposed to internal combustion engine vehicles, electric cars have fewer moving parts and require less upkeep, service, and oil changes.


Petrol, diesel vs electric cars comparison : Government Incentives

The Indian government has launched a number of programmes to support electric vehicles but does not offer incentives for petrol or diesel automobiles

EVs are eligible for purchasing incentives, tax breaks, and reduced GST rates.

Regarding the base models for all three fuel types, Tata states that the 1.5-liter manual diesel engine and the 1.2-liter turbocharged petrol engine achieve 17.33 and 23.22 kilometres per litre, respectively, in the manual avatar. In contrast, the Nexon EV Prime can travel 312 kilometres on a full charge


While coal-fired power plants do not produce no emissions, data by Bloomberg NEF indicates that carbon dioxide emissions from battery-powered automobiles were approximately 40% lower last year than from internal combustion engines.

Electric cars are dependent on the local electrical network for charging. With the exception of Southeast Asia, this benefit will increase as generators move away from coal and use more electricity from wind and solar farms. This shift is currently occurring globally. A projected drop in CO2 equivalent emissions through 2030 has been predicted as a result of an increase in electric transportation on global roadways, according to the International Energy Agency's (IEA) 2019 Global EV Outlook: Scaling up the transition to electric mobility. In 2018, EVs worldwide released


about 38 Mt CO2-eq, down from 78 Mt in 2018. Even though using coal to power an EV is less environmentally beneficial than utilising energy from renewable sources, coal-fired fuelled EVs are still just as efficient as internal combustion engine (ICE) vehicles. This is because the electricity source of EVs must be taken into account when calculating the total vehicle efficiency.

According to Bloomberg's investigation, although China, which relies more on coal, saw the largest increase in vehicle efficiency, EVs were still more efficient there. This was especially true in the UK, which has a major renewable energy sector. An electric vehicle's motor can convert coal-fired energy into power with an efficiency of about 85 to 90 percent.


Low output engines also have very low efficiency. Fossil fuel power plants, on the other hand, aim for between 40 and 55 percent thermodynamic efficiency in their design and operation. In actuality, an EV charged by a generator running on petrol would use less petrol overall than a traditional car.

Arguments regarding the emissions of EV batteries have also been brought up by the production process and the procurement of raw materials (discussed in this article from a previous one). According to a recent Science Direct study, the location of a battery's manufacturing has a significant influence on the emissions produced during this process, even though the pollution produced during the extraction and production of batteries is either the same or slightly higher than that produced during the manufacturing of petrol or diesel-powered engines.

There is a chance that CO2 emissions in China and other major manufacturing markets could be significantly reduced as Li-ion battery and other alternative battery manufacturing techniques advance, as does the EV industry's and retired EV batteries' recycling and re-use strategies

"Recent studies that look at the whole life cycle of various vehicle types and their well-to-wheel data have shown that electric cars were found to have lower levels of greenhouse gas production even with fossil fuel-based electricity generation and power losses during gearbox from electricity generation to battery filling. Compared to identical ICE vehicles, EVs emit 40% less greenhouse gas emissions, even on Australia's coal-rich grid. In fact, according to their well-towheel estimates, an average gasoline vehicle needs 1.36kWh of energy to travel one km, whereas an average electric car uses just 0.28kWh of energy—nearly five times less energy than an average gasoline vehicle”



The future is looking to be increasingly electric more electricity grids are now moving towards increasing their renewable energy production, EVs are producing fewer emissions through their lifetime regardless of the energy source, and car manufactures are looking to produce more EV alternatives for the mass-market, with many carmakers announcing plans to bring electric versions of their vehicles to market in the next few years.
