Is the MG 4 EV really cheaper than petrol?
The MG 4 EV starts at ₹30.0 Lakh ex-showroom — about 28% more than an equivalent petrol car in the same segment. That upfront gap is the usual sticking point for buyers. But electric cars make up for it on running cost. Here's the honest 5-year math.
The verdict
Over 5 years, the MG 4 EV saves you approximately ₹3.18 Lakh compared to an equivalent petrol car. At current prices, the MG 4 EV breaks even against petrol in about 8.0 years of ownership.
Why EVs win on running cost
- Fuel — At ₹8/kWh, the MG 4 EV costs roughly ₹0.53/km. A petrol car doing 18 km/L at ₹105/L costs ₹5.83/km — nearly 10.9× more.
- Maintenance — EVs have no engine oil, spark plugs, timing belts, clutch, or exhaust. Expect ~₹5,000/year for the MG 4 EV vs ~₹18,000/year for an equivalent petrol car.
- Insurance — EV policies are ~15% cheaper on average (lower IDV depreciation, government push).
- Resale — EV resale has improved sharply since 2023. After 5 years, premium EVs hold 55-60% of value vs 45-50% for petrol.
The environmental case
Over 5 years at 40 km/day, the MG 4 EV saves approximately 6 tonnes of CO₂ vs an equivalent petrol car — equivalent to planting ~280 trees or removing ~1 passenger cars off Indian roads for a year. Even accounting for India's coal-heavy grid (which we factor into the calculations), EVs come out clearly ahead.
When petrol still makes sense
EVs aren't automatic winners for every buyer. Petrol can win when:
- You drive less than 20 km/day (break-even stretches to 7+ years)
- You don't have home charging (DC-only cost can be 2-3× home rates)
- You plan to sell within 2 years (upfront premium doesn't get recovered)
- You regularly drive 500+ km inter-city trips without charging stops
Our methodology
We use India's CEA grid emission factor (0.71 kg CO₂/kWh), average domestic electricity tariff (₹8/kWh), current national petrol average (₹105/L), body-type-specific mileage baselines, and 5-year depreciation curves derived from used-car market data. All numbers update with the sliders above. Read our full methodology.
