While the government is pushing carmakers in 2019 to standardise a handful of safety features, like ABS and driver's side airbag on every car model, it's fuel efficiency that is usually on the top of the priority list of most car buyers. No surprise, then, that car manufacturers have been trying to outdo each other in the 'mileage' stakes. Here is a list of Top-10 most fuel efficient cars in India to give you an idea about the mind-boggling ARAI-certified fuel economy these models provide -
Top 10 Most Fuel Efficient Cars in India
Maruti Swift Diesel - 28.4 km/l
With an average monthly sale of 17,755 units*, the latest-gen Maruti Swift is the top-seller in the B1 segment. Its diesel variant offers an ARAI-certified fuel efficiency of 28.4 km/l, thereby making it the most fuel-efficient car on sale in the country. It's powered by the D13A 1.3-litre diesel engine that outputs 75 PS and 190 Nm. Transmission options include a 5-speed manual and a 5-speed AMT. It may be noted here that with the oil-burner won't be compliant with the BSVI emission norms that kick in next year. Hence, in all probability, the diesel version of the popular hatchback will face the axe.
Maruti Dzire Diesel - 28.4 km/l
The third-gen Maruti Dzire (average monthly sale - 20,695 units*) shares aplenty with the latest Swift, which means it gets the same D13A oil-burner with a maximum power/torque of 75 PS/190 Nm and an ARAI-certified fuel efficiency of 28.4 km/l. While both the new Swift and the new Dzire use the same engines as the second-gen models, they are more fuel efficient owing to the weight savings that were made possible with the usage of the lightweight HEARTECT platform.
Maruti Ciaz Diesel - 28.09 km/l
With an average monthly sale of 5,142 units (from August-December 2018), the updated Ciaz is the country's largest-selling C2-segment sedan. As per ARAI, the diesel engine variant of this sedan offers an astonishing 28.09 km/l, which makes it the second-most fuel efficient car in India. Powering the Ciaz D is a VGT-equipped D13A 1.3-litre oil-burner that outputs 90 PS and 200 Nm. It comes mated to 5-speed manual transmission. Another highlight is its SHVS mild-hybrid technology that optimises the motor's fuel efficiency. Maruti is said to be close to introducing the E15A 1.5-litre diesel motor in the Ciaz. The engine will gradually completely replace the 1.3-litre option.
Honda Amaze Diesel MT - 27.4 km/l
The second-gen Honda Amaze has been quick with establishing itself in the C1-segment of our car market. Its monthly sales average stands at 7,364 units*, which is second only to that of the Maruti Dzire. With an ARAI-certified fuel efficiency of 27.4 km/l, its diesel engine variant is the fourth-most fuel-efficient car on sale in the country. It draws power from a 1.5-litre iDTEC motor that outputs 100 PS and 200 Nm with a 5-speed manual transmission, and 80 PS and 160 Nm with a CVT. It may be noted that the latter even offers a lower ARAI-stated fuel efficiency of 23.8 km/l.
Maruti Baleno Diesel - 27.39 km/l
The Maruti Baleno has been the highest selling B2 segment hatchback with a monthly sales average of 17,124 units*.

It outputs 75 PS and 190 Nm and offers an ARAI-tested fuel efficiency of 27.39 km/l. While the high fuel efficiency should impress those with high usage, the performance-enthusiasts can go for the 1.0-litre Boosterjet-equipped RS variant, which outputs 101 PS and 150 Nm along with a reasonable high fuel efficiency of 21.1 km/l. The Maruti Baleno is about to receive a mid-life facelift, which will bring in minor visual updates and reportedly a set of new features.
