Maruti Suzuki Is India's CNG King: 7 Out Of India's Top 10 Selling CNG Cars Are Marutis
India’s passenger vehicle landscape is undergoing a major structural shift, and CNG cars are right at the center of it. CNG as a fuel is rapidly gaining acceptance here. In the financial year 2026 (FY2026), CNG -powered vehicles crossed the 10-lakh sales milestone and now enjoys a 22 percent market share. Also, this is the second straight year in which CNG has overtaken diesel in popularity. Let’s take a look at India’s top 10 best-selling CNG cars.
The increase in acceptance for CNG vehicles is real. More interesting is the fact that a handful of high-volume models from a single carmaker are driving the trend.
Let’s start with some numbers. India’s passenger car market posted sales of around 47 lakh units in the financial year 2026. 10.14 lakh units out of these were CNG-powered. This growth in popularity is backed by the cost benefits, expanding CNG infrastructure and an increasing number of factory-fitted CNG products being rolled out. For most people, CNG has already become the ideal diesel alternative.
When we look at the top 10 rankings, seven best-selling CNG models in FY2026 so far have been from Maruti Suzuki. Two are from Tata Motors and one is from Hyundai.
At the top spot is the Maruti Suzuki Ertiga CNG. It continues to be in great acceptance and sold 1,45,480 units in FY26. That’s roughly 14.3% of total CNG vehicles sold here. Its badge-engineered sibling, the Toyota Rumion, has a significantly lower representation of 1.6% or 15,992 units.
The Ertiga has solid footprints in both private and fleet segments, and comes in a seven-seater layout. It is loved for its solid value proposition and good ride quality. Two mid-high trims get CNG options- VXi (O) and ZXi (O). The CNG version uses the 1.5-litre K15C bi-fuel engine as its base and comes only with a manual transmission.
The MPV comes with a factory-fitted 60L CNG tank that occupies the lower half of the boot area, leading to a slight compromise in luggage space. This can particularly be a problem when all three rows are occupied and there’s luggage to carry. The CNG-powered Ertiga has an ARAI-certified mileage of 26.11 km/kg, and typically delivers around 24 km/kg.
Taking the second spot is the Maruti Dzire CNG. It sold 1,35,330 units, translating to 13.3 percent of the total CNG count. Like the Ertiga, the Dzire too has strong footholds in private and commercial segments, and the same has helped it rack up numbers. The Dzire and Ertiga together, account for approximately 27.6 percent of total CNG car sales. That shows how much a strong presence in the fleet segment can influence CNG numbers.
The Dzire is currently in its fourth generation. The CNG setup here uses the 1.2L Z12E petrol engine as its base. The CNG version makes slightly less power than the pure-petrol version- 69 hp and 101.8 Nm. Like the Ertiga, CNG-powered Dzire is also available only with a five-speed manual transmission.
It, however, has an ARAI mileage of 33.73 km/kg. Owners typically report around 28 km/kg under real-world usage. This makes running costs exceptionally low and has also contributed well to shaping its acceptance here, particularly in the fleet segment.
In addition to low running costs, people also like the Dzire CNG for its ride quality, feature-rich cabin, good service support and strong resale value. The only downside would be the compromise in boot space brought about by the 55-litre CNG tank. The Dzire’s boot is smaller than those of rivals like the Honda Amaze- it can only accommodate 382 litres. The CNG tank eats significantly into this.
Ranking third in CNG sales is the Maruti Wagon R- the tall boy hatchback that holds a lot of relevance even in 2026 with its affordable placement and value-centric packaging. It sold 96,381 units in FY2026. On the Wagon R, CNG option is available on two primary variants- LXi and VXi.
These are powered by the 1.0L K10C bi-fuel engine, mated to a five-speed transmission. This setup has an ARAI fuel efficiency of 34.05 km/kg. The 60-litre tank sits in the boot, making it nearly unusable. The advantage, however, is massive cost savings.
Maruti Brezza is at the fourth spot, selling 71,329 units in the financial year. This translates to a 7.0% representation. It uses the 1.5L 4-cylinder engine as its base and makes 87 hp and 121.5 Nm on CNG. The CNG version comes with a 55-litre CNG tank that sits inside the boot.
Limited boot space is probably the only complaint one would have about this car. The upcoming facelift is expected to address this concern as it is likely to feature underbody CNG tank. The current SUV has an ARAI mileage of 25.51 km/kg. People love the Brezza for its smart packaging and good build quality.
At the fifth spot is the Tata Nexon iCNG that sold 69,168 units during the period, translating to a 6.8% contribution. The Nexon CNG was India’s first CNG product to use a turbocharged petrol engine as its base. It delivers 99 hp and 170 Nm in CNG mode and can be had with an AMT automatic transmission as well. It has an ARAI fuel efficiency of 24 km/kg.
The advantage here is in how the CNG is packaged within the vehicle. Tata Motors uses a twin-cylinder technology- two interconnected cylinders instead of a large single-piece unit- to store CNG. This ensures usable boot space- something that’s missing on multiple hot-selling Maruti Suzuki models. People also love the CNG-powered Nexon for its modern, feature-rich cabin, high safety standards and crashworthiness, and good ride quality.
At the sixth spot is the Tata Punch iCNG that posted sales of 67,468 units (6.6 percent). Its 1.2L CNG powertrain makes 71hp and 103 Nm, and is available with manual and AMT automatic transmissions. This setup has an ARAI mileage of 26.99 km/kg. Like the Nexon, the Punch CNG also has a technology-packed cabin and high safety standards. Here too, the CNG is packaged in two interconnected cylinders, ensuring usable boot space.
Maruti Eeco ranks seven in this list, having sold 66,675 units (6.6%). The Eeco has been around for a long time, but still stays relevant in multiple markets and roles. Its 1197cc engine makes 71hp and claims a mileage of 26.78 km/kg. It comes with a 65-litre CNG tank, mounted in the boot area. The Eeco offers unmatched cabin space for the price and the same is its biggest selling point. We can find Eecos being deployed in both passenger and cargo roles.
Hyundai Aura CNG takes the eighth spot, selling 62,612 units during the period- 6.2% contribution to the CNG space. Its 1.2-litre Kappa 4-cylinder bi-fuel engine makes 67hp and 95.2 Nm. It claims a mileage of 28 km/kg. Hyundai uses dual-cylinder technology to store CNG and the same ensures a usable boot space. This is a major advantage that the Aura CNG has over the Dzire CNG.
At the ninth position is the Maruti Suzuki Fronx CNG that sold 54,805 units. It uses the 1.2-litre K-Series Dual Jet engine as its base and claims to deliver 28.51 km/kg. It comes with a 55-litre CNG tank.
Finally, at the 10th spot is the Maruti Suzuki Victoris- the carmaker’s first model to feature a factory-fitted underbody CNG tank. It sold just 35,677 units, effectively translating to a contribution of 3.5 percent. It uses the 1.5L 4-cylinder petrol engine as its base and claims a fuel efficiency of 27.02 km/kg. This SUV is loved by many for its good looks, smart interior packaging, long list of equipment and strong safety rating/crashworthiness.
