In recent years, fuel efficiency in vehicles has garnered a lot more attention than before, owing to several factors – the most crucial among them being a sustained rise in fuel prices.

While fuel economy or a car’s mileage may not be the only factor to look into before purchasing a car, it is certainly one of the more important features of a vehicle that plays a role in its performance.

Nevertheless, let us now look at some of the best mileage diesel cars in India!
