Top 10 Most Fuel-Efficient Cars in India Under 10 Lakh
Fuel efficiency, also known as fuel economy, measures how far a vehicle can travel on a certain amount of fuel. It is typically expressed in kilometres per litre (Km/L). Fuel efficiency indicates the distance an automobile can cover using a specific volume of fuel. If a vehicle is not properly maintained, its systems, including those that impact fuel efficiency, may not operate effectively.
Vehicles with higher fuel efficiency consume less fuel to perform the same tasks. Therefore, choosing a fuel-efficient vehicle offers several advantages, including a reduced carbon footprint, decreased oil dependence, and fuel cost savings. In 2025, fuel efficiency is the top priority for Indian car buyers, especially considering the rising fuel prices and increased environmental awareness.
