If you're comparing **energy efficiency** (how far an EV travels per unit of electricity), the most useful metric is **km/kWh** (higher is better) or **Wh/km** (lower is better). Here's a comparison of popular EVs available or expected in the Indian market in 2026, using a mix of manufacturer specifications and independent real-world testing where available. | Model | Battery | Approx. efficiency | Notes | |-------|---------:|-------------------:|-------| | MG Comet EV | 17.3 kWh | **≈13.3 km/kWh** | One of India's most efficient EVs; optimized for city driving. | | Tata Tigor EV | 26 kWh | **≈12.1 km/kWh** | Excellent efficiency for urban commuting. | | Tata Tiago EV | 24 kWh | **≈7.8–8.5 km/kWh** (real world) | Affordable and efficient for mixed driving. | | Tata Punch EV | 25–35 kWh | **≈8–9 km/kWh** | Good balance of efficiency and practicality. | | Mahindra BE 6 | ~59–79 kWh | **≈6.5–7.5 km/kWh** | Larger SUV; prioritizes performance and range. | | BYD Seal | 61–82.5 kWh | **≈7.9 km/kWh** | High-performance sedan with good highway efficiency. | ### Most efficient by category - **City driving:** MG Comet EV - **Best affordable all-rounder:** Tata Tiago EV - **Best compact SUV:** Tata Punch EV - **Best long-distance efficiency:** BYD Seal - **Best premium SUV:** Mahindra BE 6 (trades some efficiency for size and performance) ### Running cost comparison Assuming home charging at **₹8 per kWh**: | Efficiency | Cost per km | |------------:|------------:| | 13 km/kWh | ~₹0.62/km | | 10 km/kWh | ~₹0.80/km | | 8 km/kWh | ~₹1.00/km | | 7 km/kWh | ~₹1.14/km | For comparison, a petrol car delivering **15 km/L** with petrol at **₹105/L** costs about **₹7/km**, so even less-efficient EVs are substantially cheaper to run. Overall, if your priority is **maximum efficiency and lowest electricity cost**, the **MG Comet EV** remains the benchmark among mass-market EVs in India. If you need a practical family car with strong efficiency, the **Tata Punch EV** and **Tata Tiago EV** offer some of the best balances of price, range, and operating cost.
