That's ₹4.13 L saved in fuel alone over 5 years of owning the Rolls-Royce Rolls Royce Spectre, vs driving an equivalent petrol car.
How much does the Rolls-Royce Rolls Royce Spectre really cost to run?
At India's average residential electricity rate of ₹8/kWh, the Rolls-Royce Rolls Royce Spectre runs at approximately ₹1.54 per km — based on its efficiency of 5.2 km per kWh. For context, an equivalent petrol car doing 14 km/L at ₹105/L costs ₹7.50/km — nearly 4.9× more.
The per-km math
| EV efficiency | 5.2 km / kWh |
| Electricity cost | ₹8 / kWh (India avg) |
| EV running cost | ₹1.54 / km |
| Petrol mileage | 14 km / L |
| Petrol cost | ₹105 / L (India avg) |
| Petrol running cost | ₹7.50 / km |
What this means monthly
At the default Indian urban commute of 50 km/day (≈1,500 km/month):
- Rolls-Royce Rolls Royce Spectre electricity cost: ₹2,308/month
- Equivalent petrol cost: ₹11,250/month
- Monthly savings: ₹8,942/month
Over 5 years that's approximately ₹5.37 L saved in fuel alone — before counting maintenance and insurance savings.
Why electricity is cheaper
Burning 1 litre of petrol releases about 9.1 kWh of usable energy — but a petrol engine only converts ~20-25% of that to actual motion. The rest is heat lost through the radiator and exhaust. EVs convert ~85-90% of stored battery energy into motion. So you're paying for 4× less energy waste with an EV. That's the real reason the Rolls-Royce Rolls Royce Spectre crushes petrol on per-km cost — not because electricity is cheap in India (it isn't particularly), but because EVs are simply more efficient.
Caveats to the math
- DC fast charging (public networks) costs 2-3× home rates. The Rolls-Royce Rolls Royce Spectre would cost ₹3.85/km on DC if you charge exclusively there — still cheaper than petrol.
- Electricity slabs — once you cross 500 units/month, your tariff jumps. Most EV owners stay in the 300-500 slab shown above.
- Battery degradation — after 5-7 years, the Rolls-Royce Rolls Royce Spectre's usable range drops 10-15%, which raises per-km cost slightly.
- Solar — if you have rooftop solar, the Rolls-Royce Rolls Royce Spectre can run at ~₹0.50/km during daylight charging.
