7 Best SUVs With a CNG Option Under Rs 25 Lakh in India (2026)

Seven SUVs in India offer a factory-fitted CNG option under ₹25 lakh, and the whole field sits below ₹14 lakh. The cheapest is the Maruti Fronx Sigma CNG at ₹7.94 lakh, the most efficient is the same car at 28.51 km/kg, and the most powerful is the Tata Nexon at 100 PS. A ₹25 lakh ceiling turns out to be far more headroom than this segment actually uses.

Running an SUV on CNG used to mean accepting a short list of small, entry-level bodies and whatever the tank did to the boot. That limit has moved. Factory CNG now reaches genuine mid-size SUV bodies, and tank engineering has changed enough that the old assumption about lost cargo space no longer holds across the board.

What has not changed is that the fine print matters more than the fuel. A factory system and a dealer retrofit are different purchases, running cost swings by nearly 5 km/kg across this list, and a naturally aspirated engine on gas rarely matches its petrol-only sibling. This list ranks seven SUVs under ₹25 lakh on those terms.

Key takeaways

• Every factory CNG SUV in India costs under ₹14 lakh. The ₹25 lakh ceiling is not a constraint in this segment, it is a formality.
• Maruti Fronx: the cheapest entry at ₹7.94 lakh and the efficiency leader at 28.51 km/kg.
• Maruti Victoris: the only car here with an underbody CNG tank rather than a cylinder in the cargo area, and the only one holding 5-star ratings from both Bharat NCAP and Global NCAP.
• Maruti Brezza: the only one whose CNG trim carries an electric sunroof, and the only one with a six-speed gearbox on gas.
• Tata Punch: the only CNG SUV in India offering an automatic gearbox, on its higher AMT trims.
• Hyundai Exter: a dual-cylinder Hy-CNG layout that lets Hyundai keep an underbody spare wheel.
• Tata Nexon: the only turbocharged CNG SUV sold here, and the only one below 25 km/kg.

The seven compared

Model (CNG trim)	Price	Engine on CNG	Mileage	Gearbox
Maruti Fronx (Sigma CNG)	₹7.94 lakh	77.5 PS, 98.5 Nm	28.51 km/kg	5-speed MT
Tata Punch (Adventure CNG)	₹8.59 lakh	72 PS, 103 Nm	26.99 km/kg	5-speed MT
Hyundai Exter (SX CNG)	₹9.16 lakh	68 PS, 95.2 Nm	27.1 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
Maruti Victoris (LXi CNG)	₹11.55 lakh	87.8 PS, 121.5 Nm	27.02 km/kg	5-speed MT
Maruti Grand Vitara (Delta CNG)	₹13.48 lakh	87.8 PS, 121.5 Nm	26.6 km/kg	5-speed MT
Tata Nexon (Fearless+ CNG)	₹13.72 lakh	100 PS, 170 Nm	24 km/kg	6-speed MT
Where these numbers come from. The Maruti power, torque and mileage figures are read off Maruti's own current brochures, and the Fronx and Victoris prices off the NEXA and Arena price pages. Tata and Hyundai do not publish comparable brochure specification tables, so the Punch, Nexon and Exter figures are the best available published numbers rather than manufacturer spec-sheet entries. None of the Maruti brochures prints a boot volume for a CNG variant, so any CNG boot figure quoted below is a reported one and is described as such.

How these were shortlisted

Every car here had to clear three bars: a CNG system fitted by the manufacturer on the assembly line rather than a dealer-installed kit, a confirmed ex-showroom price under ₹25 lakh for that specific CNG trim, and a published mileage figure. Retrofit options are excluded, which is why the Renault Kiger and Nissan Magnite do not appear: both are currently offered only as authorised dealer-fitted conversions, with no official CNG-mode mileage or power published.

1. Maruti Fronx (Sigma CNG)

Price: ₹7,93,900 ex-showroom. The better-equipped Delta CNG is ₹8,73,900.

Fitting: factory-fitted S-CNG.

The Fronx is the cheapest way into a factory CNG SUV and the most efficient car in the segment. Unlike several rivals at this price, it does not cut safety kit to get there.

Features: 6 airbags standard, ABS with EBD, ISOFIX anchorages, reverse parking sensors with infographic display, idle start-stop.

Engine on CNG: 77.5 PS at 6,000 rpm and 98.5 Nm at 4,300 rpm from the 1.2-litre K-Series.

Mileage: 28.51 km/kg, the best in the segment.

Boot space: the Fronx brochure prints 308 litres for both petrol engines and leaves the CNG column blank, so Maruti does not state what the tank costs.

Gearbox: 5-speed manual.

2. Tata Punch (Adventure CNG)

Price: about ₹8.59 lakh ex-showroom.

Fitting: factory-fitted twin-cylinder iCNG.

The Punch is the only CNG SUV in India available with an automatic gearbox, though not on this trim: the AMT arrives higher up the CNG range. Its twin-cylinder tank is designed to leave more usable boot than a single large cylinder.

Features: 360-degree camera on this trim, automatic climate control, 6 airbags standard, stability and traction control.

Engine on CNG: 72 PS and 103 Nm from the 1.2-litre Revotron.

Mileage: 26.99 km/kg.

Gearbox: 5-speed manual on this trim, with AMT offered higher in the CNG range.

3. Hyundai Exter (SX CNG)

Price: about ₹9.16 lakh ex-showroom. The better-equipped SX(O) CNG is about ₹9.40 lakh.

Fitting: factory-fitted dual-cylinder Hy-CNG.

Hyundai's Hy-CNG Duo layout uses two smaller cylinders rather than one large one, which is what lets the Exter keep an underbody spare wheel rather than surrendering that space.

Features: rear parking sensors with camera, height-adjustable driver's seat, 6 airbags standard, ABS with EBD, stability control.

Engine on CNG: 68 PS and 95.2 Nm from the 1.2-litre Kappa.

Mileage: 27.1 km/kg, second only to the Fronx here.

Gearbox: 5-speed manual.

4. Maruti Brezza (ZXi CNG)

Price: ₹11.55 lakh ex-showroom, the top of three CNG trims. Maruti offers CNG on LXi, VXi and ZXi, and not on the ZXi+.

Fitting: factory-fitted S-CNG.

The Brezza is the only car here whose CNG trim carries an electric sunroof, and the only one with a six-speed gearbox on gas rather than a five-speed.

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 standard with stability control.

Engine on CNG: 87.8 PS at 5,500 rpm and 121.5 Nm at 4,200 rpm from the 1.5-litre K15C.

Mileage: 26.90 km/kg.

Gearbox: 6-speed manual.

The Brezza's 360 View Camera and 10.1-inch screen are both ZXi+ features, and CNG is not offered on that trim, so no Brezza CNG has either.

5. Maruti Victoris (LXi CNG)

Price: ₹11,54,900 ex-showroom for the entry CNG trim. VXi CNG is ₹12,89,900 and ZXi CNG ₹14,82,300.

Fitting: factory-fitted S-CNG with an underbody tank.

The Victoris mounts its cylinder beneath the body rather than inside the cargo area. It is the only car here to do so, and the only one on this list with a current 5-star result from both Indian and international crash-test programmes.

Features: SmartPlay Pro touchscreen, push-button start, 6 airbags standard, ABS with EBD, stability control.

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

Mileage: 27.02 km/kg.

Boot space: Maruti's Victoris brochure prints no boot volume for any variant. The 439-litre figure widely quoted for the petrol and hybrid cars is a reported one, and the underbody tank is designed to protect most of that on CNG rather than leave it untouched.

Gearbox: 5-speed manual.

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

6. Maruti Grand Vitara (Delta CNG)

Price: about ₹13.48 lakh ex-showroom for the entry CNG trim. The higher Zeta MT CNG is about ₹14.60 lakh.

Fitting: factory-fitted S-CNG.

The Grand Vitara is one of only two genuine mid-size SUVs here, bringing full-size cabin space to a fuel usually confined to compact bodies.

Features: automatic climate control, height-adjustable driver's seat, cruise control, rear parking sensors, 6 airbags standard, ABS with EBD, stability control, hill-hold assist.

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

Mileage: 26.6 km/kg.

Gearbox: 5-speed manual.

Maruti's main Grand Vitara brochure does not break the CNG variants out separately, so the equipment above reflects the Delta specification generally. The Grand Vitara offers no ADAS on any trim.

7. Tata Nexon (Fearless+ CNG)

Price: about ₹13.72 lakh ex-showroom for the best-equipped CNG trim.

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

The Nexon is the only turbocharged CNG SUV on sale in India, which makes it the most powerful car here by 12 PS. It is also the only one that pays for that power at the pump.

Features: twin-cylinder tank, automatic climate control, 6 airbags standard, stability control.

Engine on CNG: 100 PS and 170 Nm from the 1.2-litre three-cylinder turbo-petrol.

Mileage: 24 km/kg, the lowest here.

Gearbox: 6-speed manual.

Conclusion

CNG in this price band has outgrown the idea that it is a compromise made on a smaller car to save fuel. Genuine mid-size cabin space now comes with a factory tank, and tank design has moved far enough that a full boot and a gas cylinder are no longer automatically in conflict.

That does not make these seven interchangeable. Mileage, output and how much cargo space survives the tank vary widely, and a lower price does not reliably predict where a car lands on any of them: the cheapest car here is also the most efficient, while the second most expensive is the least. The more useful observation is that the ₹25 lakh ceiling never binds. Every factory CNG SUV in India today costs under ₹14 lakh, so the real decision is which compromise suits, not how much to spend.

FAQs

Which SUV here has the cheapest CNG option?

The Maruti Fronx, at ₹7.94 lakh for the Sigma CNG trim.

Which has the best CNG mileage?

The Maruti Fronx again, at 28.51 km/kg, with the Hyundai Exter closest at 27.1 km/kg.

Are there mid-size SUVs with factory CNG under ₹25 lakh?

Two: the Maruti Grand Vitara and the Maruti Victoris, both priced well under ₹15 lakh on CNG. The Toyota Hyryder is a third badge on the same underlying car as the Grand Vitara.

Does a CNG tank always reduce boot space?

Not equally. The Victoris mounts its tank under the body rather than in the boot, and the Exter and the two Tatas use dual or twin-cylinder layouts designed to limit the loss. Maruti does not publish CNG boot volumes at all, so exact comparisons are not possible from official figures.

Why are the Nissan Magnite and Renault Kiger not here?

Both are offered only as authorised dealer-fitted retrofits rather than factory systems, and neither manufacturer publishes official CNG-mode mileage or power.
