6 Best SUVs With a CNG Option Under Rs 20 Lakh in India (2026)

Six SUVs in India offer factory CNG on a trim under ₹20 lakh. Raising the ceiling from ₹15 lakh adds exactly one car to the list, the Toyota Hyryder in its better-equipped G CNG grade at about ₹15.72 lakh, and that is the most useful thing this price band reveals: the extra ₹5 lakh buys equipment, not a wider choice of models or a single extra gearbox option.

Push a CNG SUV budget from ₹15 lakh to ₹20 lakh and the engines do not change. What changes is which trim the CNG system is allowed to sit on. Features that stay locked to an entry CNG variant under ₹15 lakh start appearing on the gas car itself once the ceiling moves, because manufacturers will finally pair factory CNG with something above their base grade.

This list compares six SUVs on that basis, each in the best-equipped CNG trim that clears ₹20 lakh.

Key takeaways

• Nothing here offers an automatic. All six are manual-only on CNG at every trim, so a bigger budget does not buy a CNG automatic in this segment.
• Toyota Hyryder G CNG is the one car the higher ceiling adds, and it brings a panoramic sunroof and ventilated seats the base S CNG does not get.
• Maruti Fronx Delta CNG remains the efficiency leader at 28.51 km/kg and the cheapest way in at ₹8.74 lakh.
• Maruti Victoris ZXi CNG posts the best mid-size mileage at 27.02 km/kg and is the only car here with 5-star results from both Bharat NCAP and Global NCAP.
• Tata Nexon is the only turbo, at 100 PS, and the only one under 25 km/kg.
• Maruti Brezza ZXi CNG is still capped at the ZXi trim: Maruti does not offer CNG on the ZXi+, so the extra headroom buys nothing here.

The six compared

Model (CNG trim)	Price	Engine on CNG	Mileage	Gearbox
Maruti Fronx (Delta CNG)	₹8.74 lakh	77.5 PS, 98.5 Nm	28.51 km/kg	5-speed MT
Maruti Brezza (ZXi CNG)	₹11.55 lakh	87.8 PS, 121.5 Nm	26.90 km/kg	6-speed MT
Tata Nexon (Creative+ PS CNG)	₹12.80 lakh	100 PS, 170 Nm	24 km/kg	6-speed MT
Maruti Grand Vitara (Zeta CNG)	₹14.60 lakh	87.8 PS, 121.5 Nm	26.6 km/kg	5-speed MT
Maruti Victoris (ZXi CNG)	₹14.82 lakh	87.8 PS, 121.5 Nm	27.02 km/kg	5-speed MT
Toyota Hyryder (G CNG)	about ₹15.72 lakh	87.8 PS, 121.5 Nm	26.6 km/kg	5-speed MT
Where these numbers come from. Power, torque and certified mileage for the Marutis and the Toyota come from those manufacturers' own brochures, and the Fronx and Victoris prices from the NEXA and Arena price pages. Toyota publishes no ex-showroom prices in India, so both Hyryder figures quoted here are dealer-listed. Tata does not publish an equivalent specification table, so the Nexon figures are the best available published ones. No brochure here prints a boot volume for a CNG variant.

What the higher ceiling actually buys

• A better Toyota, and only a better Toyota. The Hyryder is the single model whose CNG range extends past ₹15 lakh. Every other car on this list tops out below it, so for five of the six the extra headroom changes nothing.
• Not an automatic. This is worth stating plainly because it is the most common assumption. No SUV sold in India pairs factory CNG with an automatic gearbox above ₹15 lakh. The only CNG automatics in the SUV space sit below this band, on the Tata Punch.
• Not more power. The three Maruti mid-size cars and the Toyota all run the same 87.8 PS tune on gas. Spending more does not move that number.
• Lower running cost is not on the menu either. The cheapest car here is also the most efficient, so mileage and price move in opposite directions across this list.

1. Maruti Fronx (Delta CNG)

Price: ₹8.74 lakh ex-showroom, the upper of two Fronx CNG trims. Sigma CNG is ₹7.94 lakh.

Fitting: factory-fitted S-CNG.

The Fronx is the efficiency benchmark for CNG SUVs in India. At this ceiling it costs less than half the price of the two mid-size Marutis while returning more per kilogram than either.

Features: 6 airbags standard with ESP and hill-hold, automatic climate control with rear AC vents, rear parking sensors, 60:40 split-folding rear seat, keyless entry.

Engine on CNG: 77.5 PS at 6,000 rpm, 98.5 Nm at 4,300 rpm.

Mileage: 28.51 km/kg.

Gearbox: 5-speed manual.

Neither Fronx CNG trim gets the 360 View Camera or Head-Up Display, both of which are Alpha-only.

2. Maruti Brezza (ZXi CNG)

Price: ₹11.55 lakh ex-showroom.

Fitting: factory-fitted S-CNG.

The Brezza is the clearest illustration of why a higher budget does not always help. Maruti sells CNG on LXi, VXi and ZXi, and simply does not offer it on the ZXi+. A buyer with ₹20 lakh cannot get a better-equipped Brezza on gas than a buyer with ₹12 lakh.

Features: single-pane electric sunroof, 17.78 cm touchscreen with wireless Android Auto and Apple CarPlay, automatic climate control with rear AC vents, wireless charging, 6 airbags with ESP and hill-hold.

Engine on CNG: 87.8 PS at 5,500 rpm, 121.5 Nm at 4,200 rpm.

Mileage: 26.90 km/kg.

Gearbox: 6-speed manual, the only six-speed on this list.

The 360 View Camera and the 10.1-inch screen are ZXi+ features, so no Brezza CNG has either.

3. Tata Nexon (Creative+ PS CNG)

Price: about ₹12.80 lakh ex-showroom.

Fitting: factory-fitted twin-cylinder iCNG, 60 litres combined and rated at 9 kg.

The Nexon is the outlier on this list in both directions. It is the only turbocharged CNG SUV here, giving it a 12 PS advantage over the K15C cars, and it is the only one that gives up meaningful efficiency for it.

Features: panoramic sunroof, 10.25-inch touchscreen with wireless Android Auto and Apple CarPlay, 360-degree camera, cooled glovebox, hill-hold control, ISOFIX anchorages.

Engine on CNG: 100 PS and 170 Nm.

Mileage: 24 km/kg, the lowest here.

Gearbox: 6-speed manual.

4. Maruti Grand Vitara (Zeta CNG)

Price: about ₹14.60 lakh ex-showroom. Maruti's price page lists two CNG trims, Delta MT CNG and Zeta MT CNG, but the main brochure does not break the CNG variants out separately, so the equipment below reflects the Zeta specification generally.

Fitting: factory-fitted S-CNG.

The Grand Vitara's CNG range stops at Zeta, so like the Brezza it gains nothing from the higher ceiling. What it offers is genuine mid-size cabin space on gas, with the Victoris as its only real alternative.

Features: 22.86 cm touchscreen with Android Auto and Apple CarPlay, wireless charging, automatic climate control with rear AC vents, cruise control, 6 airbags with stability control.

Engine on CNG: 87.8 PS at 5,500 rpm, 121.5 Nm at 4,200 rpm.

Mileage: 26.6 km/kg.

Gearbox: 5-speed manual.

The Grand Vitara offers no ADAS on any trim, in any fuel.

5. Maruti Victoris (ZXi CNG)

Price: ₹14.82 lakh ex-showroom, the top of three CNG trims. LXi CNG is ₹11.55 lakh, VXi CNG ₹12.90 lakh.

Fitting: factory-fitted S-CNG with an underbody tank rather than a cylinder in the cargo area.

The Victoris makes the strongest all-round case here. It returns the best mid-size mileage, uses the only underbody tank on the list, and carries crash-test credentials nothing else here can match.

Features: 17.78 cm touchscreen with wireless Android Auto and Apple CarPlay, wireless charging, LED headlamps and DRLs, 17-inch alloys, rear camera, auto-dimming mirror, tyre pressure monitoring, 6 airbags with ESP and hill-hold.

Engine on CNG: 87.8 PS at 5,500 rpm, 121.5 Nm at 4,200 rpm.

Mileage: 27.02 km/kg.

Gearbox: 5-speed manual.

Safety: 5-star Bharat NCAP, 31.66 of 32 adult and 43 of 49 child occupant protection, plus a separate 5-star Global NCAP result for both.

The Victoris does have Level 2 ADAS, but only on the Smart Hybrid petrol automatic. No CNG trim gets it.

6. Toyota Hyryder (G CNG)

Price: about ₹15.72 lakh ex-showroom, a dealer-listed figure since Toyota publishes no ex-showroom prices in India. This is the trim that a ₹15 lakh ceiling puts out of reach.

Fitting: factory-fitted CNG with a boot-mounted cylinder.

The Hyryder is built alongside the Grand Vitara and runs the same engine to the same numbers. What the G grade adds over the base S is equipment, and it is the one place on this list where a bigger budget genuinely buys a better car rather than the same car at a different badge.

Features: 22.86 cm touchscreen with wireless Apple CarPlay and Android Auto, panoramic sunroof, wireless charging, ventilated front seats, height-adjustable driver's seat, automatic climate control, cruise control, 6 airbags with ABS, EBD and stability control.

Engine on CNG: 87.8 PS at 5,500 rpm, 121.5 Nm at 4,200 rpm.

Mileage: 26.6 km/kg.

Gearbox: 5-speed manual.

Conclusion

Going from ₹15 lakh to ₹20 lakh buys better equipment on exactly one car and nothing at all on the other five, because most CNG ranges in India simply stop below ₹15 lakh. That is the real finding here, and it is more useful than a ranking: if the Hyryder G CNG's sunroof and ventilated seats are not what you want, there is no reason to spend above ₹15 lakh in this segment.

Mileage still moves in the opposite direction to price across the whole list, and no amount of budget buys an automatic. A buyer whose priority is running cost is better served at the bottom of this table than the top.
