Is the Tata Tata Altroz EV really cheaper than petrol?
The Tata Tata Altroz EV starts at ₹0 ex-showroom — about NaN% less 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 Tata Tata Altroz EV saves you approximately ₹4.32 Lakh compared to an equivalent petrol car. The Tata Tata Altroz EV is already cheaper than its petrol alternative from day one.
Why EVs win on running cost
- Fuel — At ₹8/kWh, the Tata Tata Altroz EV costs roughly ₹0.80/km. A petrol car doing 18 km/L at ₹105/L costs ₹5.83/km — nearly 7.3× more.
- Maintenance — EVs have no engine oil, spark plugs, timing belts, clutch, or exhaust. Expect ~₹5,000/year for the Tata Tata Altroz 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 Tata Tata Altroz EV saves approximately 4 tonnes of CO₂ vs an equivalent petrol car — equivalent to planting ~197 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.
