BYD Atto 3 Cost Per Km — How Much Does It Really Cost to Drive?
The BYD Atto 3 achieves an impressive per-kilometer cost of just ₹0.93 on electricity. Its 60.5 kWh battery pack delivers 521 km on a single charge, making it one of the most economical vehicles to operate in India. For comparison, a petrol car costs ₹7/km — making the BYD Atto 3 87% cheaper per kilometer.
The cost per km varies by driving conditions. In city traffic with frequent stops, the BYD Atto 3 actually becomes even cheaper (₹0.79/km) thanks to regenerative braking that recovers energy while slowing down. A petrol car's cost spikes to ₹9.10/km in stop-and-go traffic due to engine idling.
Charging method significantly impacts cost per km. Home charging at off-peak night rates (₹5/kWh) brings the cost down to just ₹NaN/km. Even premium DC fast charging at ₹18/kWh costs only ₹NaN/km — still dramatically cheaper than ₹7/km for petrol.
For a driver covering 40 km daily, the monthly difference is stark: ₹1,116 for the BYD Atto 3 vs ₹8,400 for petrol — a saving of ₹7,284 every month that adds up to ₹4.37 L over 5 years in fuel costs alone.
