Anticipating traffic and letting "single-pedal driving" do the work sends energy back to the battery, boosting efficiency. * **The Air Conditioning Tax:** The intense Indian summers demand aggressive cabin cooling. Continuous AC usage can drop an EV’s overall efficiency and range by **10% to 15%**. * **Highway Speeds:** EV efficiency drops drastically at speeds above **90–100 km/h** due to aerodynamic drag. An EV that gets 9 km/kWh in the city might drop to 6.5 km/kWh on an express highway. ## The Financial Takeaway In terms of running costs, an efficient EV in India costs approximately **₹1.00 to ₹1.50 per km** when charged at home (based on average domestic electricity slabs). In comparison, a refined petrol automatic car costs roughly **₹7.00 to ₹9.00 per km** in city traffic. Are you looking to evaluate a specific model for a daily commute, or trying to decide if an EV makes financial sense for your annual mileage?
