Best CNG Compact SUVs Under ₹15 Lakh in India (2026)

Six factory-fitted CNG compact SUVs currently sell for under ₹15 lakh in India: the Tata Punch (₹6.85 lakh to ₹10.77 lakh), Hyundai Exter (₹7.00 lakh to ₹9.57 lakh), Maruti Suzuki Fronx (₹7.89 lakh to ₹8.74 lakh), Toyota Taisor (approximately ₹8.71 lakh), Maruti Suzuki Brezza (₹9.35 lakh to ₹11.71 lakh) and Tata Nexon (₹9.57 lakh to ₹13.72 lakh). Mileage runs from 28.51 km/kg on the Fronx and Taisor, which share the same CNG hardware, down to 17.44 km/kg on the Nexon, which is also the most powerful of the six at 98.59 PS and the only one offering ADAS on a CNG variant.

If you're shopping for compact SUVs on running costs, a factory-fitted CNG option is worth serious consideration over a petrol variant or an aftermarket retrofit kit. Factory-fitted means the CNG system is engineered and warrantied by the manufacturer, tested alongside the rest of the car rather than added on afterward by a third party. That usually means better tuning, safety certification, and resale value.

This list covers six compact SUVs that offer exactly that, all under 15 lakh, so you can compare them properly before deciding.

Key takeaways:

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

Best CNG compact SUVs under 15 lakh in India

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	8	₹9.57L to ₹13.72L	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 Tata, Hyundai and Toyota either block automated access or do not publish ARAI-certified CNG mileage, so those figures are our own and are worth confirming with a dealer.

1. Maruti Suzuki Brezza

CNG Price Range: ₹9.35 lakh to ₹11.71 lakh.

The Brezza's CNG tank is mounted underbody rather than inside the boot, a genuine engineering difference from most rivals here. It also carries over the electric sunroof to its top CNG trim, something few compact SUV CNG variants offer at all.

Key features:

• Underbody-mounted S-CNG tank
• Electric sunroof (ZXi CNG)
• PM2.5 cabin air filter
• Day/night auto-dimming rearview mirror
• Height-adjustable driver seat
• Keyless entry
• ISOFIX child seat mounts
• 7-inch touchscreen with wireless Android Auto and Apple CarPlay
• Steering-mounted controls

Engine: 1.5-litre K15C, producing 87.8 PS (64.6 kW) and 121.5 Nm in CNG mode.

Transmission options: 6-speed manual only.

Warranty: 3 years or 1,00,000 km, extendable up to 6 years.

Safety: 6 airbags standard across every CNG-eligible trim. No ADAS.

2. Maruti Suzuki Fronx

CNG Price Range: ₹7.89 lakh to ₹8.74 lakh.

The Fronx's Delta CNG trim is better equipped than it might look at first glance. You get a genuinely usable feature set here, not just the bare essentials.

Key features:

• Height-adjustable driver seat
• 60:40 split rear seats with recline and slide
• 2nd row AC vents
• PM2.5 cabin air filter
• Dedicated CNG fuel gauge with total CNG mode time display

Mileage: 28.51 km/kg.

Transmission options: 5-speed manual only.

Warranty: 3 years or 1,00,000 km, whichever comes first.

Safety: 6 airbags standard. No ADAS.

3. Tata Punch

CNG Price Range: ₹6.85 lakh to ₹10.77 lakh.

The Punch is the most affordable car on this list, and its top CNG trim is more feature-rich than that low starting price suggests, sunroof included. It's one of only three cars here, along with the Brezza and the Nexon, that offers one on CNG. It's also the only car on this list available with an automatic transmission on CNG, a genuine rarity in a segment where CNG almost always means manual-only.

Key features:

• Sunroof (Accomplished Dazzle S CNG and above)
• 10.25-inch floating touchscreen with wireless Android Auto and Apple CarPlay
• 7-inch digital instrument cluster
• Automatic climate control
• Cruise control
• Air purifier
• Wireless phone charger

Engine: 1.2-litre Revotron, producing 73.4 PS and 103 Nm.

Mileage: 26.99 km/kg.

Transmission options: 5-speed manual, with an AMT automatic available on the top CNG trim.

Safety: 5-star Bharat NCAP rating. 6 airbags on higher trims. No ADAS.

4. Tata Nexon

CNG Price Range: ₹9.57 lakh to ₹13.72 lakh.

The Nexon is the only car on this list with ADAS available on a CNG variant, on the top Fearless+ PS trim. Its turbo-petrol engine also gives you noticeably more power than any rival here, though that comes at the cost of the weakest CNG mileage figure in this comparison.

Key features:

• Panoramic sunroof (Fearless+ PS)
• Harman infotainment system with 10.25-inch touchscreen (Fearless+ PS)
• Ventilated front seats (Fearless+ PS)
• Air purifier with dust sensors (Fearless+ PS)
• Wireless charger (Fearless+ PS)
• Leather-wrapped steering wheel (Fearless+ PS)
• 360-degree camera (Fearless+ PS)
• Rear AC vents

Engine: 1.2-litre turbo-petrol, producing 98.59 PS and 170 Nm in CNG mode.

Mileage: 17.44 km/kg.

Transmission options: 6-speed manual only.

Safety: 5-star Global NCAP rating. 6 airbags standard. ADAS available on the top Fearless+ PS trim, covering forward collision warning, autonomous emergency braking, lane departure warning, lane keep assist, high beam assist, and traffic sign recognition.

5. Hyundai Exter

CNG Price Range: ₹7.00 lakh to ₹9.57 lakh.

The Exter is the only car on this list with a factory-fitted dual-camera dashcam, a genuinely distinctive feature at this price point. It uses a dual-cylinder tank design that Hyundai says preserves 225 litres of boot space, officially confirmed on Hyundai's own website and a useful figure to know since most rivals don't publish theirs at all. It doesn't get a sunroof on CNG, though. That's reserved for a petrol-only top trim.

Key features:

• Dual-camera dashcam
• Dual-cylinder CNG technology
• 8-inch touchscreen with wireless Android Auto and Apple CarPlay
• Automatic climate control
• Digital instrument cluster
• Rear AC vents
• Push-button start/stop
• Rear parking camera
• Tyre pressure monitoring system
• Follow-me-home headlamps
• Power-adjustable ORVMs

Engine: 1.2-litre Kappa, producing 69 PS and 95.2 Nm.

Mileage: 27.1 km/kg.

Transmission options: 5-speed manual only.

Safety: 6 airbags standard. No ADAS. Not yet crash tested by Global NCAP or Bharat NCAP.

6. Toyota Taisor

CNG Price Range: Approximately ₹8.71 lakh, offered only on the base E trim.

The Taisor shares its underlying platform and CNG hardware with the Fronx, but Toyota restricts the CNG option to a single base trim. This is a straightforward, no-frills pick rather than one with multiple CNG variants to choose between.

Key features:

• Keyless entry
• Automatic climate control
• Hill hold assist
• ABS with EBD
• Tyre pressure monitoring system

Engine: 1.2-litre, producing approximately 77-78 PS, shared with the Fronx CNG.

Mileage: 28.51 km/kg.

Transmission options: 5-speed manual only.

Safety: 6 airbags standard. No ADAS. Not yet crash tested by Global NCAP or Bharat NCAP.

Conclusion

Factory-fitted CNG in the compact SUV segment has moved well beyond a basic running-cost add-on. The six cars on this list show real variation in how much power, boot space, and equipment carry over to the CNG variant, so it's worth looking past the badge and checking what the specific CNG trim actually offers before you decide. The Punch and Exter make the cheapest entry, the Fronx and Taisor are the most efficient at 28.51 km/kg, and the Nexon is the only one here with turbo power and ADAS.
