Electric vehicles promise dramatically lower running costs than petrol cars, but how big is the actual difference in India? Using the popular Tata Nexon (petrol vs EV versions) as a benchmark, here’s a clear, numbers-driven comparison including home charging, public networks like Jio-bp Pulse, and real-world factors.
Key Assumptions for Fair Comparison (2026 Prices)
- Petrol Nexon: Real-world efficiency ~12-14 km/l (city-highway mix; ARAI claims ~17 kmpl). Petrol price: ₹100-105/litre (national average ~₹105/l).
- Nexon EV (e.g., 45 kWh long-range): Real-world efficiency ~7-9 km/kWh (city often better; highway ~6.5-7.5 km/kWh). Home electricity: ₹6-9/kWh average.
- Annual driving: 12,000-15,000 km (typical Indian usage).
- Charging mix: Mostly home + occasional public fast charging.
Cost Per Kilometer BreakdownPetrol Nexon:
- At 13 km/l real-world and ₹105/litre → ₹8.08 per km.
- Full tank (44L) costs ~₹4,600 and delivers ~570 km real-world range → expensive for daily use.
Nexon EV:
- Home charging (₹8/kWh, 8 km/kWh efficiency) → ₹1.00 per km (often as low as ₹0.70-0.90).
- Public charging (e.g., Jio-bp Pulse or similar networks at ₹13-20/kWh) → ₹2.00-2.50 per km.
- Full charge cost at home: ~₹300-400 (for ~45 kWh usable) delivering 300-370+ km real-world range.
Savings: EV running cost is 75-90% lower than petrol. Even with frequent public charging, it’s 60-75% cheaper.
Real-World Monthly & Annual SavingsAssume 1,500 km/month (50 km/day) mixed driving:
- Petrol: ~115 litres/month → ₹12,000-12,500/month (~₹1.5 lakh/year).
- EV Home Charging: ~190-220 kWh/month → ₹1,500-2,000/month (~₹20,000-25,000/year).
- Monthly Savings: ₹10,000+.
- Annual Savings: ₹1.2-1.5 lakh on energy alone.
Over 5 years (75,000 km): Fuel/charging savings can exceed ₹5-7 lakh, often offsetting the higher upfront price of the EV.
Home vs Public Charging: Jio-bp Pulse and Others
- Home (cheapest): Overnight AC charging via wallbox or regular socket. Rates ₹5-9/unit depending on state and time-of-day tariffs. Most cost-effective for daily commuters.
- Public Fast Charging (Jio-bp Pulse): Convenient at petrol pumps and highways. Rates typically ₹13-20+/kWh (subscription plans can lower to ~₹18-20/kWh). Good for top-ups or trips, but 2-3x costlier than home. Jio-bp offers app-based payments, cashback, and subscriptions for regular users.
- Mixed Reality: Many owners charge 80-90% at home and use public networks for long trips. Effective cost stays under ₹1.50/km.
Additional Savings Beyond Fuel
- Maintenance: EVs have no oil changes, fewer brake jobs (regen braking), and simpler powertrains → 50-70% lower service costs (₹4,000-6,000/year vs ₹12,000-18,000 for petrol).
- Insurance & Other: Often comparable or slightly higher initially but offset by lower overall ownership costs.
- Total 5-Year TCO: Many analyses show Nexon EV breaking even in 2.5-4 years and saving ₹3-5+ lakh overall versus petrol.
Factors That Affect Savings
- Driving Style & Conditions: Aggressive driving or heavy AC use reduces EV efficiency more noticeably.
- Electricity Rates: Vary by state (cheaper in some, higher in others).
- Temperature: Extreme heat/cold impacts battery range.
- Usage Pattern: High daily km favors EVs more.
The Bottom Line: EVs Are Significantly Cheaper to Run
For the Tata Nexon, charging an EV costs roughly 1/7th to 1/8th of petrol at home — and still far cheaper even at public stations like Jio-bp Pulse. A typical owner can save ₹1 lakh+ per year on running costs, making the switch financially compelling beyond environmental benefits. As charging infrastructure expands and electricity remains cheaper than petrol, the gap will likely widen. For urban and suburban drivers with home charging access, the economics strongly favor EVs today.
