Petrol vs. Electric
Comparing two identical cars, one with a petrol engine and the other with an electric motor (EV), is an interesting exercise, especially when it comes to fuel efficiency. Though the two powertrains operate differently, we can still compare their energy efficiency to understand how they perform on the same route.
Let’s consider a popular example to make the comparison clearer: the Tata Nexon, which is available in both petrol and electric versions.
1. Tata Nexon Petrol vs. Tata Nexon EV: Fuel Efficiency Comparison
Tata Nexon Petrol
- Engine Type: 1.2L Turbocharged Petrol
- Fuel Efficiency: Around 17-18 km/l (depending on driving conditions)
- Fuel Cost: Petrol in India costs around ₹100 per liter (this varies regionally).
Tata Nexon EV
- Motor Type: Electric Motor with a Lithium-Ion battery
- Energy Efficiency: Around 3.5 to 4.5 km/kWh (depending on the model, driving conditions, and battery charge level)
- Charging Cost: Electricity cost in India averages around ₹7 to ₹10 per kWh (again, this varies by region and electricity provider).
How to Compare Fuel Efficiency:
- Tata Nexon Petrol Efficiency:
- Fuel Efficiency: 17-18 km/l.
- For 1000 km:
- 1000 km ÷ 17 km/l = 58.8 liters of petrol needed.
- 58.8 liters × ₹100 = ₹5880 for a 1000 km journey.
- Tata Nexon EV Efficiency:
- Energy Efficiency: 3.5 to 4.5 km/kWh.
- For 1000 km:
- 1000 km ÷ 4.0 km/kWh = 250 kWh of electricity needed (based on average efficiency).
- 250 kWh × ₹8 per kWh = ₹2000 for a 1000 km journey (using ₹8/kWh as the average cost of electricity).
Fuel Efficiency Comparison (Cost per 1000 km):
- Tata Nexon Petrol: ₹5880 for 1000 km.
- Tata Nexon EV: ₹2000 for 1000 km (using ₹8/kWh electricity cost).
Key Points of Comparison:
- Fuel Efficiency:
- The Tata Nexon EV is far more efficient in terms of cost, as it uses electricity to power the car, which is generally cheaper per km compared to petrol.
- While the petrol version of the Nexon achieves around 17-18 km/l, the Nexon EV achieves 3.5-4.5 km per kWh, which results in much lower running costs for an electric car.
- Energy Cost:
- Petrol typically costs around ₹100 per liter, which makes running a petrol car more expensive, even with an efficient engine.
- Electricity, on the other hand, is much cheaper on a per-kWh basis (roughly ₹7-10), making the EV the more economical choice for long-term fuel costs, assuming you have access to affordable electricity.
- Environmental Impact:
- The EV has a significant edge in terms of environmental impact, as it produces zero tailpipe emissions, unlike petrol vehicles that emit CO2 and other pollutants.
- Even accounting for the electricity generation process (which can involve fossil fuels), the EV typically results in fewer emissions, especially if charged using renewable energy sources.
Conclusion:
- For fuel efficiency, the Tata Nexon EV is far superior to the petrol version when comparing the cost per km of running. An electric vehicle offers significant savings on running costs, with charging costs being a fraction of the cost of petrol.
- The petrol Nexon may still be a good option for those who prefer the convenience of refueling at petrol stations, or those who may not have access to EV charging infrastructure or range anxiety. However, the EV is the clear winner in terms of efficiency and operational costs for long-term use.

Ford F-150 in India vs. Ford F-150 Lightning (Electric) – Fuel Efficiency and Cost (in INR)
While the Ford F-150 is not officially available in India, let’s break down the fuel efficiency and the potential costs for both gasoline and electric versions of the F-150 in terms of Indian Rupees (INR), based on typical fuel and electricity rates in India.
1. Fuel Efficiency of Ford F-150 (Gasoline) – Indian Context
Gasoline Ford F-150 (Petrol or Diesel Models)
As mentioned earlier, the gasoline F-150 comes in several engine variants, with fuel efficiency typically ranging from 17 to 24 mpg depending on the engine size. To make it more relevant for India, let’s look at the average mileage and cost of fuel (petrol).
Average Fuel Efficiency (for gasoline engine):
- Around 20 mpg combined for a typical 3.3L V6 engine in real-world conditions.
Converting Miles to Kilometers:
- 1 mile = 1.60934 kilometers
- 20 miles per gallon (mpg) = 32.2 kilometers per liter (km/l)
So, if we assume an F-150 achieves around 32.2 km/l in mixed driving conditions, the next step is calculating the fuel cost.
Fuel Cost in India (Petrol):
- Current average petrol price in India: Approximately ₹100 per liter (this can vary by region).
Example Cost of Fuel for Gasoline F-150:
If you drive 100 km with the F-150’s 32.2 km/l efficiency:
- Fuel consumed = 100 km / 32.2 km/l = 3.11 liters
- Fuel cost = 3.11 liters × ₹100 = ₹311 for 100 km.
2. Electric Ford F-150 Lightning – Energy Efficiency and Cost in INR
Electric Ford F-150 Lightning Efficiency (MPGe)
The Ford F-150 Lightning (Electric version) uses electricity rather than gasoline, and its efficiency is measured in MPGe (miles per gallon equivalent). As discussed, the F-150 Lightning typically provides about 65-70 MPGe.
Average MPGe for Lightning:
Let’s use 70 MPGe for simplicity, which is about 70 miles per 1 gallon of gasoline equivalent.
To convert MPGe to kilometers per kWh (kilowatt-hour), we need to use the following formula:
- 1 gallon of gasoline equivalent (GGE) = 33.7 kWh (Energy content of 1 gallon of gasoline).
- So, if the F-150 Lightning offers 70 MPGe, it means it travels 70 miles on the energy equivalent of 1 gallon of gasoline.
- 1 GGE = 33.7 kWh → 70 miles = 33.7 kWh
- Therefore, the F-150 Lightning consumes 33.7 kWh / 70 miles = 0.48 kWh per mile.
Now, let’s convert this into kilometers per kWh:
- 0.48 kWh per mile = 0.48 kWh per 1.60934 km = 0.298 kWh per kilometer.
Cost of Charging the F-150 Lightning in India:
- The cost of electricity in India varies, but on average, it can be around ₹8-₹10 per kWh for residential consumers.
Example Cost of Charging for Electric F-150 Lightning:
If the F-150 Lightning consumes 0.298 kWh per kilometer:
- Cost per kilometer = 0.298 kWh × ₹10 = ₹2.98 per kilometer (at ₹10 per kWh).
- For 100 km, the cost would be around ₹298.
3. Comparison of Fuel Costs (Gasoline vs. Electric F-150)
Let’s compare the cost per 100 km for both the gasoline-powered Ford F-150 and the electric F-150 Lightning in India:
Vehicle | Fuel Type | Fuel Efficiency | Cost per 100 km (INR) |
---|---|---|---|
Ford F-150 (Gasoline, 3.3L V6) | Petrol | 32.2 km/l | ₹311 |
Ford F-150 Lightning (Electric) | Electric | 0.298 kWh/km | ₹298 |
Key Insights:
- Fuel Efficiency:
- The gasoline Ford F-150 offers a fuel efficiency of around 32.2 km/l, meaning it will cost about ₹311 per 100 km when running on petrol.
- The electric F-150 Lightning is more energy-efficient, consuming about 0.298 kWh per km and costing ₹298 per 100 km to operate.
- Cost of Fuel vs. Charging:
- Gasoline is typically more expensive than electricity in India. For instance, petrol costs around ₹100 per liter, while the cost of electricity is much lower, typically around ₹8-₹10 per kWh for residential users.
- The electric F-150 Lightning proves to be slightly more cost-effective on a per-kilometer basis compared to the gasoline-powered F-150, despite the high initial cost of the vehicle and the electricity infrastructure needed.
- Range and Charging Considerations:
- Gasoline-powered F-150 can cover 500-700 km on a single tank of fuel, offering a longer range compared to the electric F-150 Lightning, which offers 230-320 km of range depending on the battery variant.
- For the F-150 Lightning, charging infrastructure and the availability of fast-charging stations in India would play a significant role in the practicality of owning an electric vehicle. Charging times are also a consideration.
4. Example: Cost for Driving 1,000 km
Let’s calculate the approximate cost to drive 1,000 km with each vehicle.
Gasoline Ford F-150:
- Fuel Efficiency: 32.2 km/l
- Fuel Cost: ₹100 per liter
- Fuel consumed for 1,000 km = 1000 km / 32.2 km/l = 31.06 liters
- Fuel cost = 31.06 liters × ₹100 = ₹3,106 for 1,000 km.
Electric Ford F-150 Lightning:
- Energy Efficiency: 0.298 kWh/km
- Electricity Cost: ₹10 per kWh
- Electricity consumed for 1,000 km = 1000 km × 0.298 kWh/km = 298 kWh
- Charging cost = 298 kWh × ₹10 = ₹2,980 for 1,000 km.
Conclusion:
- The Ford F-150 Lightning (Electric) is slightly cheaper to operate on a per-100 km basis in India (around ₹298) compared to the gasoline-powered Ford F-150 (around ₹311 per 100 km), mainly due to lower electricity costs.
- However, the gasoline-powered F-150 has the advantage of longer range per tank, and refueling is quicker and more convenient than charging an electric vehicle (especially in India, where charging infrastructure may not be as widespread as in some other countries).
- The electric F-150 Lightning would be ideal for those looking to reduce their environmental footprint, lower running costs, and have access to adequate charging infrastructure.
In a practical sense, if electricity is easily available and you’re not concerned about the range limitations, the F-150 Lightning would be the more cost-efficient choice in terms of fuel costs. Otherwise, for those relying on gasoline, the F-150 (petrol or hybrid) remains a solid choice for longer trips and areas with limited charging infrastructure.
huge difference in fuel efficiency between vehicles like the Ford F-150 (32.2 km/l for its gasoline engine) and many vehicles in India like Toyota models (often around 10 km/l or less for larger engines). There are several factors that contribute to this disparity in fuel efficiency between vehicles sold in different markets, including differences in engine design, vehicle weight, driving conditions, and regulations. Let’s break down the reasons for this discrepancy:
1. Engine Technology and Design
- Ford F-150 (32.2 km/l in the U.S.):
The Ford F-150 is available with advanced engine technologies, such as turbocharging (like the EcoBoost engines), which significantly improve the vehicle’s fuel efficiency by extracting more power from smaller, more efficient engines. In addition to turbocharging, the F-150 is also designed with the American market’s driving conditions in mind, where highway driving is prevalent, which benefits from engines optimized for cruising at higher speeds with lower fuel consumption. - Toyota Vehicles in India (10-15 km/l):
On the other hand, many of Toyota’s larger vehicles in India, such as the Fortuner, Innova, or Hilux, are equipped with larger, more powerful naturally aspirated engines (e.g., 2.8L diesel, 2.7L petrol). These engines, while strong for towing and off-roading, tend to have lower fuel efficiency compared to turbocharged engines. Moreover, many of the vehicles sold in India are still geared towards more traditional powertrains, which have slightly lower fuel efficiency compared to more advanced technologies in markets like the U.S.
2. Vehicle Weight and Size
- Ford F-150:
The F-150 is designed as a full-size pickup truck, but it’s also built using lightweight materials, including aluminum in its body and frame. This helps reduce weight and improve fuel efficiency, as lighter vehicles require less power to move. Additionally, the truck’s larger, but aerodynamically efficient design allows it to achieve better fuel economy on highways. - Toyota in India:
Many of the vehicles Toyota sells in India, especially SUVs like the Fortuner or Innova, are heavier compared to their U.S. counterparts. They are built with sturdier frames, designed for rugged conditions and off-road capabilities, which often means they have a higher curb weight. More weight requires more energy (fuel) to move, which directly impacts fuel efficiency.
3. Driving Conditions
- United States:
In the U.S., much of the driving happens on highways, where cars can cruise at higher speeds with lower fuel consumption. The F-150, being designed for long-distance travel, benefits from steady highway driving, which typically yields better fuel economy compared to stop-and-go city driving. Additionally, American consumers generally do more highway driving than urban driving. - India:
In India, driving conditions are quite different. In cities, there is a lot of stop-and-go traffic, frequent idling, and frequent use of the AC, which tends to reduce fuel efficiency. Many of the popular SUVs and vehicles sold in India are designed for more challenging road conditions (like rough roads, potholes, and poor infrastructure). This type of driving requires the engine to work harder, further lowering fuel economy.
4. Fuel Quality and Type
- Fuel Quality in the U.S.:
The fuel in the U.S. tends to have higher octane ratings (typically 91 or 93) and cleaner formulations, which allows modern engines, especially turbocharged ones like those in the F-150, to run more efficiently. The U.S. also uses higher-quality additives in their fuels that improve engine performance and fuel efficiency. - Fuel Quality in India:
In India, the quality of petrol and diesel can vary greatly, and often it is not as high as in countries like the U.S. Lower-quality fuel may contain impurities that can reduce engine performance, meaning cars have to work harder to achieve the same efficiency. Additionally, some Indian vehicles still use lower-octane petrol (around 87 RON), which may affect the engine’s efficiency, particularly in older or larger engines.
5. Regulations and Market Preferences
- Fuel Efficiency Regulations in the U.S.:
The U.S. has stringent fuel economy regulations and corporate average fuel economy (CAFE) standards, which have pushed manufacturers to make engines that are both powerful and fuel-efficient. Ford’s EcoBoost technology and the PowerBoost Hybrid option for the F-150 are examples of how manufacturers have prioritized fuel efficiency in the U.S. market. - Fuel Efficiency in India:
In India, while fuel efficiency is important, there has been less regulatory pressure on larger vehicles to meet fuel economy standards. Many SUVs and trucks sold in India are designed for rugged use, off-roading, or for commercial purposes, and thus may prioritize power and durability over fuel efficiency. While Toyota has focused on improving fuel efficiency with some newer models (like the hybrid Innova Crysta), larger SUVs still tend to have lower efficiency compared to compact cars.
6. Transmission and Gear Ratios
- Ford F-150:
The Ford F-150 typically uses modern transmissions like 10-speed automatic gearboxes in some variants, which are optimized for both performance and fuel efficiency. The larger number of gears allows the engine to maintain optimal revs, increasing fuel efficiency at highway speeds. The advanced automatic transmissions in the F-150 allow the engine to shift efficiently and maintain good power delivery. - Toyota in India:
Many of the Toyota models in India still use older transmission designs, like 5-speed or 6-speed automatics or manuals, which may not be as optimized for fuel efficiency. The higher gearing in modern vehicles like the F-150 helps reduce engine revs at highway speeds, improving fuel economy.
7. Air Conditioning and Additional Accessories
- Ford F-150:
Vehicles like the F-150 are often designed with efficiency in mind when it comes to air conditioning and other auxiliary systems. The cabin is designed for long-distance comfort, and fuel consumption is optimized during such usage. - Toyota in India:
In India, air conditioning (AC) usage is often more frequent due to the climate. Running the AC constantly, especially in heavy traffic, can reduce fuel efficiency. Vehicles designed for the Indian market are often larger, and this means more weight and higher demand on the engine, particularly for SUVs like the Fortuner or Land Cruiser.
Conclusion: Why Does the F-150 Achieve 32 km/l While Toyota in India Achieves Only 10?
- Engine Technology: Ford uses advanced turbocharged engines and hybrid options that maximize fuel efficiency, whereas Toyota’s larger engines in India tend to be less fuel-efficient.
- Vehicle Weight and Size: The F-150 is made with lightweight materials (like aluminum) that reduce its weight, whereas Toyota’s larger SUVs are generally heavier.
- Driving Conditions: Highway driving in the U.S. allows vehicles like the F-150 to perform better in terms of fuel economy, while in India, city driving and rough road conditions lead to worse efficiency.
- Fuel Quality: Higher-quality fuels in the U.S. improve the fuel efficiency of vehicles like the F-150, while lower-quality fuel in India may reduce efficiency.
- Market and Regulatory Differences: In the U.S., there are tighter fuel economy regulations, whereas in India, larger, more rugged vehicles are prioritized for towing, off-roading, and commercial use rather than fuel efficiency.
In summary, while Ford’s F-150 can achieve impressive fuel efficiency due to advanced engine technology, lightweight materials, and highway-focused design, Toyota’s vehicles in India are often heavier, designed for more rugged uses, and not optimized for maximum fuel efficiency.

Tata Nexon Petrol vs. Tata Nexon EV comparison! It’s a good example of how fuel efficiency and running costs differ significantly between petrol vehicles and electric vehicles. Let’s break down why the cost and efficiency differ in this way and how this relates to your earlier question about Ford F-150 vs. Toyota in India.
1. Why is the Comparison between Tata Nexon Petrol and Tata Nexon EV Valid?
The comparison you’ve drawn between the Tata Nexon Petrol and Tata Nexon EV shows the drastic difference in cost per kilometer between traditional fuel (petrol) and electric vehicles (EVs). Here’s why this comparison works:
Fuel Efficiency of Tata Nexon Petrol:
- The Tata Nexon Petrol has a fuel efficiency of 17-18 km/l.
- For a 1,000 km journey:
- Fuel consumed = 1000 km ÷ 17 km/l ≈ 58.8 liters of petrol.
- Fuel cost = 58.8 liters × ₹100 (average petrol price in India) = ₹5,880 for 1,000 km.
Energy Efficiency of Tata Nexon EV:
- The Tata Nexon EV consumes about 3.5 to 4.5 km per kWh of electricity, depending on the driving conditions.
- For a 1,000 km journey:
- Energy consumed = 1000 km ÷ 4 km/kWh = 250 kWh of electricity.
- Cost of electricity = 250 kWh × ₹8 (average electricity cost in India) = ₹2,000 for 1,000 km.
Cost Comparison for 1,000 km:
- Petrol Tata Nexon: ₹5,880.
- Electric Tata Nexon (EV): ₹2,000.
Key Points from the Comparison:
- The electric vehicle (EV), in this case, is much cheaper to run than the petrol car, with about 3 times lower operating costs for a 1,000 km journey.
- The major reason for this difference is that electricity is significantly cheaper than petrol. Electricity in India generally costs around ₹8 per kWh, while petrol costs around ₹100 per liter.
This massive difference in cost is one of the reasons why EVs like the Tata Nexon EV have become more attractive in recent years, especially in terms of operating expenses.
2. Why is Fuel Efficiency for Petrol Cars Lower Than Electric Cars in India?
You’ve asked how this comparison might be different for larger vehicles like the Toyota Fortuner or the Ford F-150. The same principles apply, but there are several factors that can cause fuel efficiency differences in larger vehicles (like SUVs and pickup trucks) compared to smaller vehicles like the Tata Nexon. Here’s a breakdown:
Gasoline/Petrol Cars in India (e.g., Toyota Fortuner, Toyota Innova, etc.):
- Larger Engines & Weight:
Many SUVs, like the Toyota Fortuner or Innova, are equipped with larger, heavier engines (2.7L to 3.0L engines) designed for rugged terrain, heavy load-carrying, and off-roading. Larger engines and vehicles generally consume more fuel because they need more power to move the weight. - Fuel Consumption:
Larger engines often yield lower fuel efficiency in urban traffic conditions. The Toyota Fortuner, for example, might give you only 10-12 km/l in normal driving conditions, with a mix of city and highway driving. - Driving Conditions:
Stop-and-go traffic, road congestion, and frequent idling (which happens a lot in Indian cities) result in higher fuel consumption, especially for larger vehicles. More frequent gear shifts and sudden acceleration in dense traffic can further lower fuel efficiency.
Electric Vehicles (EVs):
- Higher Energy Efficiency:
EVs like the Tata Nexon EV are much more efficient in converting energy into movement. Electric motors are typically more efficient than internal combustion engines, often converting 85-90% of electrical energy into motion. In comparison, gasoline engines only convert about 30-35% of fuel energy into motion, with the rest lost as heat and friction. - Lower Operating Costs:
Electricity is still cheaper than petrol or diesel. The Tata Nexon EV consumes 3.5 to 4.5 km/kWh, meaning you get a lot more distance per unit of energy. This results in much lower costs for driving.
3. How Does This Translate to Larger Vehicles like Ford F-150 and Toyota Fortuner?
Now, let’s relate this to the Ford F-150 and Toyota Fortuner:
Ford F-150 (Petrol and Hybrid):
- The Ford F-150 (in its petrol version) offers a fuel efficiency of around 20-24 mpg. For a 1,000 km journey, this would result in higher fuel consumption than a smaller car, but it would still cost less than a large diesel-powered SUV because of turbocharged engines and efficient transmission systems (like the 10-speed automatic).
- Ford F-150 Hybrid (with a 3.5L PowerBoost engine) would do even better, offering 24 mpg combined. However, it’s still going to be less fuel-efficient than the Tata Nexon EV, which offers approximately 4.0 km per kWh, because the electric vehicle is simply more efficient.
Toyota Fortuner (Diesel):
- The Toyota Fortuner has a diesel engine and typically offers 10-12 km/l, which is relatively low for an Indian market vehicle.
- The fuel efficiency is lower because the diesel engine is designed for power and off-road capability, and it’s a large, heavy vehicle.
- Electric Fortuner or EV alternatives to the Fortuner are not available in India yet, but if it were, it would likely offer much lower running costs (comparable to Tata Nexon EV) due to the superior efficiency of electric motors.
4. The Key Differences and Conclusion
- Fuel efficiency in traditional gasoline or diesel-powered vehicles is often lower in India because of:
- Larger, less efficient engines.
- Heavy vehicle weight.
- Rougher, stop-and-go driving conditions.
- Higher fuel costs (petrol and diesel).
- Electric vehicles (EVs) like the Tata Nexon EV are more efficient, offering better mileage per unit of energy (e.g., kWh). They also benefit from much cheaper fuel (electricity), which is why they cost significantly less to run.
In Summary:
- Petrol-powered vehicles in India (like Toyota Fortuner or Ford F-150) will generally have lower fuel efficiency (around 10-15 km/l for larger SUVs) due to engine size, vehicle weight, and driving conditions.
- Electric vehicles (like Tata Nexon EV) can achieve much higher efficiency, offering lower running costs due to more efficient powertrains and cheaper energy sources.
Even for larger vehicles, electric vehicles will likely become more cost-effective over time, as seen with the Tata Nexon EV’s running cost of ₹2,000 for 1,000 km compared to ₹5,880 for the petrol version.
