Top 10 Best Mileage CNG Cars You Can Buy In 2026

This list could very well be every Maruti CNG car on sale. The brand dominates our most efficient CNG car list thanks to lightweight bodies, skinny tyres, and large factory-fitted CNG tanks.

Do note that apart from the Dzire CNG, none of the Maruti models here have an official safety rating yet, though they do come with six airbags as standard. The Dzire and the Punch are among the safest as well as most efficient CNG cars on this list.

The Punch, along with the Exter, also offers a larger usable boot than most rivals thanks to dual cylinder CNG technology. The Punch is also among the handful of CNG cars available with an automatic gearbox option.

Apart from these there is a string chance of bigger cars like Breeza and Kylaq to enter the game with a CNG engine, making CNG even more popular with premium buyers

Maruti Suzuki Celerio

The Celerio S-CNG utilizes the 1.0L K10C Dual Jet, Dual VVT engine specifically tuned for gas. In CNG mode, it delivers a maximum power of 56.7 PS at 5300 rpm and a peak torque of 82.1 Nm at 3400 rpm. It features a factory-fitted, leak-proof S-CNG kit with a single 60L (water equivalent) tank mounted in the boot, which significantly reduces the 313-liter petrol boot capacity to approximately 160–170 liters. 

Technical safety includes a micro-switch that cuts off the engine during refueling and an integrated ECU for optimized air-fuel ratios. It is available only with a 5-speed manual transmission.

Maruti Suzuki Wagon R

Wagon R is equipped with the 1.0L K10C three-cylinder engine, producing 56.7 PS and 82.1 Nm in CNG mode. 

The fuel system includes an Intelligent Injection System that works in tandem with dual interdependent ECUs. It features a dedicated CNG fuel gauge in the digital instrument cluster and a changeover switch with an "Auto" mode that starts the car in petrol and switches to gas once the engine reaches optimal temperature.

Maruti Suzuki Alto K10

The Maruti Suzuki Alto K10 CNG is one of the most affordable factory-fitted CNG hatchbacks in India. It uses a 1.0-litre K10C three-cylinder petrol engine tuned to produce about 56.7 PS and 82 Nm when running on CNG paired with a 5-speed manual gearbox. T

he lightweight body helps it deliver an ARAI rated efficiency of around 33.85 km per kg

Maruti Suzuki Dzire

The latest Dzire represents a massive shift in Maruti’s CNG strategy. It has ditched the old four-cylinder for the new Z12E 1.2L three-cylinder engine. In CNG mode, it pushes 69.7 PS and 101.8 Nm. The highlight here isn't just the fuel efficiency; it’s the safety rating. 

This is the first Maruti CNG to come with a 5-star Global NCAP rating, proving that carrying a high-pressure tank doesn't have to compromise structural integrity

Maruti Suzuki Swift

Like its sedan sibling, the new Swift has transitioned to the Z-Series engine architecture. The 1.2L three-cylinder unit generates 69.7 PS and 101.8 Nm on gas. The Swift's CNG variant is tuned specifically for a bit more "snap" in the low-end torque to keep that sporty hatchback feel, though you do lose some top-end refinement compared to the old four-cylinder. 

The hardware includes six airbags as standard and a specialized suspension setup with higher spring rates at the rear.

Maruti Suzuki S-Presso

The S-Presso is essentially a high-riding Alto K10 with more head clearance. It utilizes the 1.0L K10C engine (56.7 PS / 82.1 Nm) and a 55L CNG tank. What makes the S-Presso unique is its 180mm ground clearance.

Maruti Suzuki Baleno

The Baleno moves into a higher performance bracket, retaining the 1.2L K12N four-cylinder Dual Jet engine for its CNG variants. This results in a much smoother power delivery and a respectable 77.5 PS and 98.5 Nm of torque. Because it’s a wider car, the 55L tank feels slightly less intrusive, though it still eats the bulk of the boot.

Toyota Glanza

The Glanza is a product of the Toyota Suzuki global partnership, taking the Baleno’s mechanical foundation and pairing it with Toyota’s reputation for reliability and long term ownership peace of mind. It shares the same 1.2L engine and similar efficiency figures as the Baleno, but the styling differences, particularly at the front, give it a slightly sharper identity. I

nside, the dual tone cabin and Toyota branding create a more premium impression. Another key factor is Toyota’s extended warranty programs and service reputation, which many buyers consider a deciding factor. .

Hyundai Exter

The Hyundai Exter is a feature rich micro SUV that introduced a fresh level of technology to the CNG segment. One of its highlights is Hyundai’s twin cylinder layout, which frees up more usable luggage space compared to traditional single cylinder setups. The 1.2L Kappa engine is known for smooth operation and refined city manners.

Hyundai has also loaded the Exter with features such as standard six airbags and an integrated dash camera system. Even its CNG versions can be equipped with a sunroof, which shows how strongly Hyundai focuses on lifestyle features. 

Tata Punch

The Tata Punch is widely regarded as one of the toughest vehicles in the micro SUV segment. Built on the ALFA architecture, it carries a 5 star safety rating which is a major selling point for safety conscious buyers. Tata’s iCNG technology in the Punch uses two smaller cylinders placed under the luggage floor, allowing the car to retain usable boot space, something traditional CNG cars often struggle with.
