Best SUVs With a CNG Option Under Rs 10 Lakh in India (2026)

Under Rs 10 lakh the Maruti Fronx Delta CNG is the straightforward answer, leading on mileage by a wider margin than separates second from fourth and the only entry that does not need the full budget. The more useful point is what the ceiling excludes: the Brezza, Punch and Nexon all sell better-equipped CNG trims above Rs 10 lakh, which is why the sunroof appears on the Punch here but not the Brezza.

Four SUVs in India offer a factory-fitted CNG trim priced under ₹10 lakh: the Maruti Fronx Delta CNG at ₹8.74 lakh, the Maruti Brezza VXi CNG at about ₹9.99 lakh, the Tata Punch at about ₹9.90 lakh and the Tata Nexon at about ₹9.99 lakh. The Fronx leads on mileage at 28.51 km/kg, and in three of the four cases the best trim under the ceiling is not the cheapest CNG variant on offer.

Sub-₹10 lakh SUVs used to mean picking between a small engine and a short feature list. CNG has shifted that. Several manufacturers now put a factory tank on a genuine SUV without crossing this ceiling, as long as you pick the right trim.

This list covers the best-equipped CNG trim from each qualifying model that stays under ₹10 lakh, not the cheapest variant available.

Key takeaways

  • Maruti Fronx Delta CNG, ₹8.74 lakh: the efficiency leader at 28.51 km/kg, and the only car here with meaningful headroom left under the ceiling.
  • Three of four entries use a mid-tier trim, not the base one. Where a model offers several CNG variants under ₹10 lakh, the better-equipped one still fits.
  • Maruti Brezza VXi CNG is the most powerful naturally aspirated option here at 87.8 PS, though the sunroof and the larger screen sit on trims above this ceiling.
  • Tata's twin-cylinder tank appears at this price point too, on both the Punch and the Nexon.
  • Tata Nexon is the only turbocharged CNG SUV in India and the only car here below 26 km/kg.

The four compared

Where these numbers come from. The Fronx and Brezza output and mileage figures are read off Maruti's own current brochures, and the Fronx prices off the NEXA price page. Tata does not publish a comparable brochure specification table, so the Punch and Nexon figures are the best available published numbers. Maruti publishes no boot volume for a CNG variant of either car, so boot figures here are reported ones.

What qualifies for this list

A model made this list only if it met all of the following: a genuine factory-fitted CNG trim priced under ₹10 lakh ex-showroom, not a petrol variant with a CNG option noted elsewhere in the range; the best-equipped qualifying trim featured rather than the cheapest, since that gives a more accurate picture of what the ceiling actually buys; retrofit kits excluded entirely, since their output and mileage are not certified; and current availability, excluding withdrawn CNG variants.

1. Maruti Fronx (Delta CNG)

Price: ₹8,73,900 ex-showroom, the better equipped of two Fronx CNG trims. The base Sigma CNG is ₹7,93,900 and returns the same mileage.

Fitting: factory-fitted S-CNG.

The Fronx leads this list on mileage by a clear 1.5 km/kg, and the Delta trim adds a real step up over the Sigma without approaching the ceiling. It is the only car here that leaves more than ₹1 lakh of the budget unspent.

Features: SmartPlay touchscreen with wireless Android Auto and Apple CarPlay, automatic climate control, rear AC vents, steering-mounted controls, 6 airbags standard with ESP and hill-hold assist, rear parking sensors.

Engine on CNG: 1,197 cc K-Series, 77.5 PS at 6,000 rpm and 98.5 Nm at 4,300 rpm.

Mileage: 28.51 km/kg.

Boot space: the Fronx brochure prints 308 litres for the petrol engines and no figure for CNG, so Maruti does not state what the tank costs in litres.

Gearbox: 5-speed manual on CNG.

2. Tata Punch (Accomplished Dazzle S)

Price: about ₹9.90 lakh ex-showroom, the highest CNG trim that stays under the ceiling.

Fitting: factory-fitted twin-cylinder iCNG, designed to preserve more usable boot than a single large cylinder.

The Punch's top qualifying CNG trim brings in equipment usually found further up a price list, including a sunroof, while posting the second-best mileage here.

Features: voice-assisted electric sunroof, touchscreen infotainment, digital instrument cluster, automatic climate control, automatic projector headlamps, 6 airbags standard.

Engine on CNG: 1.2-litre three-cylinder, 72 PS and 103 Nm.

Mileage: 26.99 km/kg.

Boot space: reported at 210 litres on the CNG variant against 366 litres on the petrol car.

Gearbox: 5-speed manual on this trim. The Punch's CNG AMT sits above this ceiling.

3. Maruti Brezza (VXi CNG)

Price: about ₹9.99 lakh ex-showroom, the highest Brezza CNG trim that stays under ₹10 lakh. The LXi CNG is cheaper, and the ZXi CNG at about ₹11.55 lakh sits above the ceiling.

Fitting: factory-fitted S-CNG.

The Brezza has the largest engine on this list and the most power on gas, and it is the only car here with a six-speed gearbox. What it does not have at this trim is the equipment the Brezza is usually sold on. Most of that lives higher up the range.

Features: 17.78 cm touchscreen with wireless Android Auto and Apple CarPlay, automatic climate control, rear AC vents, steering-mounted controls, 6 airbags standard with stability control.

Engine on CNG: 1,462 cc K15C, 87.8 PS at 5,500 rpm and 121.5 Nm at 4,200 rpm.

Mileage: 26.90 km/kg.

Boot space: reported at 328 litres on the CNG variant. Maruti's brochure prints no boot figure.

Gearbox: 6-speed manual on CNG.

Worth knowing: the electric sunroof arrives on the ZXi CNG, above this ceiling. The 360 View Camera and the 25.65 cm touchscreen sit on the ZXi+, which Maruti does not offer with CNG at all, so no Brezza CNG has either at any price.

4. Tata Nexon (Smart+ S)

Price: about ₹9.99 lakh ex-showroom, the highest Nexon CNG trim under the ceiling.

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

The Nexon trails this list on mileage, which is the trade-off for being the only turbocharged CNG SUV in India. The Smart+ S is the most complete version available under ₹10 lakh.

Features: LED headlamps, tail lamps and DRLs, 6 airbags standard, rear parking sensors, ISOFIX child seat anchors.

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

Mileage: 24 km/kg.

Boot space: reported at 321 litres on the CNG variant against 382 litres on the petrol car.

Gearbox: 6-speed manual on CNG.

Conclusion

Under ₹10 lakh the Fronx Delta CNG is the straightforward answer for anyone optimising running cost. It leads on mileage by a wider margin than separates second from fourth, and it is the only entry that does not need the full budget.

The more useful point is what this ceiling does to the other three. The Brezza, the Punch and the Nexon all sell better-equipped CNG trims, and all three of those trims sit above ₹10 lakh. A buyer holding to this budget is choosing a mid-range variant of each. That is why the sunroof appears on the Punch here but not the Brezza, even though the Brezza does offer one on a trim ₹1.5 lakh higher.

FAQs

Which SUV under ₹10 lakh has the best CNG mileage?

The Maruti Fronx at 28.51 km/kg on its Delta CNG trim, the best figure of any CNG SUV sold in India.

Is the Brezza VXi CNG the cheapest Brezza CNG?

No. The LXi CNG is cheaper. The VXi was chosen here because it is the best-equipped Brezza CNG trim that still stays under ₹10 lakh.

Can I get a CNG SUV with an automatic under ₹10 lakh?

No. The Tata Punch is the only CNG SUV in India offering an automatic, and its CNG AMT trims sit above this ceiling.

Which of these has the most powerful CNG engine?

The Tata Nexon at 100 PS from a 1.2-litre turbo-petrol, ahead of the Brezza's 87.8 PS.

Does every trim of these SUVs come with CNG?

No. CNG is limited to specific trims on each model, and the most premium trims are often not offered with it at all. The Maruti Brezza is the clearest example: its top ZXi+ trim has no CNG option at any price.
