Best CNG Compact SUVs Under ₹25 Lakh in India (2026)

Six factory-fitted CNG compact SUVs sell under ₹25 lakh in India today: the Tata Punch from ₹6.85 lakh (26.99 km/kg), Hyundai Exter from ₹7.00 lakh (27.1 km/kg), Maruti Suzuki Fronx from ₹7.89 lakh (28.51 km/kg), Tata Nexon from ₹8.30 lakh (17.44 km/kg, but 98.59 PS and the only ADAS on the list), Toyota Taisor at approximately ₹8.71 lakh (28.51 km/kg), and Maruti Suzuki Brezza from ₹9.35 lakh (26.90 km/kg). The most expensive CNG variant of any of them, the Nexon at ₹14.60 lakh, still lands a long way short of the ₹25 lakh ceiling.

CNG used to mean a trade-off: less power, a smaller boot, and a stripped-down trim with none of the features you'd actually want. That's no longer true across the board. The six compact SUVs on this list now offer factory-fitted CNG with real equipment attached, sunroofs, touchscreens, cruise control, even ADAS on one of them, at prices that stay well under ₹25 lakh. If you're weighing running costs against everyday usability, this is where that decision actually plays out.

Key takeaways:

• Lowest entry price: Punch (₹6.85 lakh), Exter (₹7.00 lakh); best all-round everyday usability: Fronx
• Boot space preserved on CNG: Exter (dual-cylinder, 225 litres confirmed), Brezza (underbody tank)
• Most power, a panoramic sunroof, and the only one with ADAS: Nexon
• Simplest single-trim pick with Toyota's reliability reputation: Taisor

Every figure below is specific to each car's CNG variant, not its petrol range, so you're seeing exactly what you'd get if you bought the CNG version, not what the badge is capable of on a different fuel.

Model	No. of CNG variants	CNG price range	Engine (CNG mode)	Mileage
Maruti Suzuki Brezza	3	₹9.35L to ₹11.71L	1.5L K15C, 87.8 PS/121.5 Nm	26.90 km/kg
Maruti Suzuki Fronx	2	₹7.89L to ₹8.74L	1.2L K-Series, 77.5 PS/98.5 Nm	28.51 km/kg
Tata Punch	5	₹6.85L to ₹10.77L	1.2L Revotron, 73.4 PS/103 Nm	26.99 km/kg
Tata Nexon	9	₹8.30L to ₹14.60L	1.2L turbo-petrol, 98.59 PS/170 Nm	17.44 km/kg
Hyundai Exter	5	₹7.00L to ₹9.57L	1.2L Kappa, 69 PS/95.2 Nm	27.1 km/kg
Toyota Taisor	1	Approx. ₹8.71L	1.2L, ~77-78 PS	28.51 km/kg

Maruti Suzuki figures come from its own brochures and price pages. Tata, Hyundai and Toyota either block automated access or do not publish ARAI-certified CNG mileage, so those figures are our own and are worth confirming with a dealer.

Things to consider if you're buying a CNG car

• CNG almost always detunes the engine: Power and torque typically drop compared to the petrol version of the same engine, since CNG burns at a different rate. Check the CNG-specific output, not the petrol figure on the brochure.
• Boot space usually takes a hit: Most CNG SUVs carry the tank inside the boot, cutting usable space, sometimes significantly. A handful of cars here use dual-cylinder or underbody designs specifically to reduce this, worth checking if boot space matters to you.
• CNG availability isn't uniform across India: Filling stations are dense in cities like Delhi NCR and Mumbai but far sparser in smaller towns and rural areas. Check local CNG infrastructure before committing, especially if you plan to drive outside a major city often.
• CNG variants are usually manual-only: Automatic transmissions on CNG are rare in this segment, and where they do exist, they're often limited to a single top trim.
• Feature availability can lag behind the petrol range: Some CNG variants miss out on things like a sunroof, ADAS, or higher-end infotainment, even when the same car offers them on petrol. Don't assume a feature carries over just because it exists somewhere in the model's range.
• Running cost savings come with a higher upfront price: CNG variants typically cost more than the equivalent petrol trim, so it's worth calculating your break-even point based on how much you actually drive.
