A majority of the car buying audience in the Indian car market is from the entry-level small car space, for whom the factor of fuel efficiency matters the most. Thankfully, the cost-conscious budget-oriented car buyers are spoilt with a lot of choices, all of which offer exceptional fuel efficiencies. Following is a list of the ten most fuel efficient petrol cars one can buy in the country today:
Maruti Suzuki Dzire
The car which revolutionized the sub-four metre sedan category in India, the Maruti Suzuki Dzire is received a major facelift in 2020, which saw the car receiving a new engine under its hood.
A step-up from the erstwhile K12 engine of the previous version of the Dzire, the new 1.2-litre four-cylinder K12N engine returns a fuel efficiency of 24.12 kmpl with the 5-speed AMT gearbox. This makes it the most fuel-efficient petrol car in the country today. Even with the standard 5-speed manual gearbox, the Dzire gives 23.26 kmpl. The engine is good enough to make 90 PS of power and 113 Nm of torque.
Maruti Suzuki Baleno
The Smart Hybrid version of the Maruti Suzuki Baleno might not be a volume bringer as strong as the regular version of the hatchback. However, the Baleno Smart Hybrid makes a lot of sense with its even better fuel economy.
Compared to the 21.01 kmpl fuel economy of standard Baleno, the Baleno Smart Hybrid promises an economy of 23.87 kmpl. The engine here is a 1.2-litre four-cylinder mill, which makes 90 PS of power and 113 Nm of torque. The engine is paired to an integrated starter generator and a 12V lithium-ion battery, which performs functions like mild power assist, idle start-stop and brake energy recuperation.
Maruti Suzuki Swift
On the lines of its sedan counterpart, the Maruti Suzuki Swift also received a minor facelift. And like the Dzire, the Swift too received a new heart in the form of a 1.2-litre K12N petrol engine, which has replaced the erstwhile K12 engine.
With a maximum power output of 90 PS and a maximum torque output of 113 Nm, the Maruti Suzuki Swift returns a fuel efficiency of 23.76 kmpl in the AMT variants and 23.2 kmpl for manual variants. The engine also features an idle start-stop system, which is a part of Baleno Smart Hybrid’s engine functions as well.

Maruti Suzuki Alto
The arrival of new generation premium mass-market offerings has left Alto a bit behind in the race of fuel economy. The Maruti Suzuki Alto was the most fuel-efficient petrol car once upon a time, and even today, it continues to be one of the best on the list.
The 0.8-litre three-cylinder engine of the Maruti Suzuki Alto, which makes 48 PS of maximum power and 69 Nm of maximum torque, ensures a fuel efficiency figure of 22.05 kmpl. The engine comes paired to a 5-speed manual gearbox as standard.
The most premium variant of the lineup of the Renault Kwid, the 1.0 AMT, also happens to be the most fuel-efficient of all. In its facelifted avatar, the 1.0-litre three-cylinder petrol engine of the Kwid was upgraded to BS6 emission norms.
The engine, which makes 69 PS of power and 91 Nm of torque, promises a fuel efficiency of 22 kmpl. Even with the 5-speed manual gearbox, this engine returns 21.74 kmpl. The entry-level 0.8-litre three-cylinder petrol engine, which is available with a standard 5-speed manual gearbox, gives 20.71 kmpl of fuel efficiency.
Ranking next in the list of the most fuel-efficient petrol cars in India is the Kwid’s distant cousin, the Datsun Redigo. The Redigo shares its platform and engine options with the Kwid but wears a completely different tall boy design and a different interior cabin.
The 1.0-litre engine, which has been shared with the Kwid in the Datsun Redigo, gives 22 kmpl with the 5-speed AMT gearbox and 21.7 kmpl with the 5-speed manual gearbox. The 0.8-litre version isn’t too far behind either, with its ARAI-claimed fuel efficiency of 20.71 kmpl.
Maruti Suzuki WagonR
In its third generation avatar, the Maruti Suzuki WagonR not only received a much more modern design in and out but also got two engine options for the first time in its history.
This tallboy stalwart from Maruti Suzuki is available with two petrol engine options – 1.0-litre three-cylinder petrol and a 1.2-litre four-cylinder petrol engine. Out of these two, the 1.0-litre petrol, which makes 69 PS of power and 90 Nm of torque, is more fuel-efficient with an ARAI-claimed figure of 21.79 kmpl. Even the more powerful 1.2-litre petrol too promises 20.52 kmpl.
Maruti Suzuki S-Presso
The 1.0-litre K10B engine has been the mainstay of Maruti Suzuki for a long time, and the S-Presso is the latest car to get this engine. The Maruti Suzuki S-Presso was launched to take on a direct rivalry with the Renault Kwid, with its SUV-esque design and high ground clearance.
The three-cylinder engine of the Maruti Suzuki S-Presso pumps out 69 PS of power and 90 Nm of torque and returns a fuel efficiency figure of 21.7 kmpl in both manual and automatic variants.
Maruti Suzuki Ignis
There is a valid reason why Indians love small cars from Maruti Suzuki this much. The list of top ten cars with the highest fuel efficiency has a total of seven cars from Maruti Suzuki, with the Ignis being the seventh of all of them.
The quirky little SUV-inspired Maruti Suzuki Ignis gets the same 1.2-litre four-cylinder petrol engine that powers the WagonR and standard versions of Baleno. Here in the Ignis, this engine breathes out 84 PS of power and 113 Nm of torque and claims a fuel economy figure of 20.89 kmpl. Like the WagonR, the Ignis too is available with both 5-speed manual and 5-speed AMT transmission options.
Hyundai Grand i10 Nios
Currently, the most fuel-efficient petrol car from the stable of the country’s second-largest carmaker Hyundai is this, the Hyundai Grand i10 Nios. The Grand i10 Nios was launched as a successor to the highly successful Grand i10, and while it is a completely different car in terms of design and interior, it gets the same engine as the latter.
The 1.2-litre four-cylinder petrol engine in the Hyundai Grand i10 Nios has been tuned for better fuel efficiency than before. This engine now produces maximum power and torque outputs of 83 PS and 113 Nm respectively, with a claimed fuel economy of 20.7 kmpl.
