Fuel efficiency has always been a big USP in selling cars or motorcycles in India, and when looking at sales the top-selling vehicles are the most fuel-efficient, or amongst the best in India. They have been affordable, small, and offer no fancy features, as their goal is to offer the best mileage per litre of petrol.
However, in recent times, things have changed. With the introduction of hybrid technology, bigger, more expensive cars beat smaller cars by a big margin in terms of fuel efficiency. Would you believe that the most fuel-efficient vehicle in India is a mid-size SUV?
Here are the most fuel-efficient petrol cars in India right now
