5 Best CNG Cars in India (2026)

Key takeaways

• Maruti Baleno: the highest CNG mileage of the five at 33.61 km/kg, from the new Z12E engine that came with the September 2026 facelift.
• Maruti Fronx: the cheapest car on this list at ₹7.89 lakh, and the only CNG option styled as a compact SUV/crossover.
• Maruti Victoris: the only car here with an underbody CNG tank, so the cylinder doesn't eat into the boot the way it does on the other four.
• Maruti XL6: the only 6-seater MPV in this list, for buyers who need CNG with three rows of seating.
• Maruti Grand Vitara: the most expensive CNG option here at ₹13.00 lakh, adding cruise control and a reverse camera, though its Delta CNG trim skips the ventilated seats, 9-inch touchscreen and wireless charging the petrol Zeta gets.

What are the benefits of having a CNG car?

• Lower running cost: CNG is priced lower per kg than petrol is per litre, and every car on this list returns 26-34 km/kg, so the fuel bill for the same distance driven comes down noticeably compared to running the same car on petrol.
• Lower tailpipe emissions: CNG burns cleaner than petrol, producing less particulate matter and lower carbon monoxide emissions, which is part of why it's pushed heavily in cities with strict pollution norms.
• Dual-fuel flexibility: all five cars here retain their petrol tank alongside the CNG kit, so you're not stranded if you can't find a CNG station and can switch back to petrol.
• Manufacturer-backed reliability: because all five are factory fitted rather than retrofit, the CNG kit is covered under a single Maruti warranty alongside the rest of the car, rather than a separate kit maker warranty.

How we shortlisted these cars

• Maruti only: this list covers five specific Maruti models with factory-fitted CNG, spanning hatchback to SUV and MPV body styles, rather than being restricted to one segment or price band.
• Factory fitted only: no retrofit kits were considered. All five get CNG from the factory, backed by a single manufacturer warranty rather than a split vehicle-plus-kit warranty.
• Current, on-sale CNG trim: pricing, features and specifications reflect the specific CNG trim each model is actually sold in today, not the wider petrol range.

All prices are for the entry-level CNG variant of each model, ex-showroom Delhi. Baleno figures are for the September 2026 facelift, whose CNG pricing and specifications Maruti published on 10 September 2026.

1. Maruti Baleno

• Pricing: ₹7.92 lakh
• Fitting: Factory-fitted CNG

The Baleno is Maruti's premium hatchback, sold through the NEXA network, and has been the best-selling car in its segment for years. It got a September 2026 facelift that brought Level 2 ADAS and ventilated seats to the petrol range, and Maruti published the updated CNG pricing on 10 September 2026. The figures below are for the Delta CNG variant, which pairs the new Z12E 1.2-litre three-cylinder engine with a 5-speed manual gearbox.

Features:

• 7-inch touchscreen with Android Auto and Apple CarPlay

• Electrically foldable ORVMs and steering-mounted audio controls

• Automatic climate control and a multi-function steering wheel

• ESP with hill-hold assist

• 6 airbags as standard

• Engine: 69 bhp, 101.8 Nm from the new Z12E 1.2-litre three-cylinder engine.

• Mileage: 33.61 km/kg, the highest of the five cars on this list.

• Boot space: 318 litres on petrol. A CNG-specific figure hasn't been published.

• Transmission: 5-speed manual only.

• Warranty: 3 years/100,000 km standard, extendable up to 6 years/160,000 km.

2. Maruti Fronx

• Pricing: ₹7.89 lakh
• Fitting: Factory-fitted CNG

The Fronx is Maruti's compact SUV/crossover, sold via NEXA, and the only Maruti model available with a turbo-petrol engine, though that option doesn't extend to CNG. This is the Sigma CNG, the range's base trim, built on the 1.2-litre naturally aspirated engine with a 5-speed manual gearbox. Being the entry trim, it comes without a touchscreen or steering-mounted controls; both arrive only from Delta trim upward on the petrol side. At just under ₹7.9 lakh, it undercuts the Baleno by ₹0.03 lakh, making the two nearly interchangeable on cost despite their different body styles.

Features:

• 6 airbags as standard

• Automatic climate control with rear AC vents

• Rear parking sensors

• 60:40 split-foldable rear seat

• Keyless entry and power windows (front and rear)

• ESC, central locking and engine immobiliser

• Engine: 76.4 bhp @ 6000 rpm, 98.5 Nm @ 4300 rpm.

• Mileage: 28.51 km/kg.

• Boot space: 308 litres on petrol. A CNG-specific figure hasn't been published.

• Transmission: 5-speed manual only.

• Warranty: 3 years/100,000 km standard, extendable up to 6 years/160,000 km.

3. Maruti Victoris

• Pricing: ₹11.55 lakh
• Fitting: Factory-fitted CNG with a segment-first underbody tank

The Victoris is Maruti's newest mid-size SUV, sold via the Arena network, and its CNG version is the first in the country to use an underbody-mounted tank instead of one in the boot. This is the LXi CNG, the entry-level trim, running the same 1.5-litre engine used across Maruti's other CNG models, paired with a 5-speed manual gearbox. Despite being the base trim, it has a fairly generous kit list for its price point, and being Maruti's most recent CNG launch, it carries the Victoris's 5-star Bharat NCAP rating. It's priced roughly ₹3.7 lakh above the Fronx, making it the natural step-up once budget allows for a larger SUV.

Features:

• 7-inch touchscreen with wireless Android Auto and Apple CarPlay

• Automatic climate control with rear AC vents

• Air purifier

• Keyless entry with push-button start

• 6 airbags, ABS with EBD, ESC, traction control and hill-hold assist

• 60:40 split-foldable rear seat

• Engine: 87 bhp, 121.5 Nm.

• Mileage: 27.02 km/kg.

• Boot space: Not published by Maruti for either the petrol or CNG variant. The underbody CNG tank is stated to leave boot capacity uncompromised, but no litre figure has been released to confirm this.

• Transmission: 5-speed manual only.

• Warranty: 3 years/100,000 km standard, extendable up to 6 years/160,000 km.

4. Maruti XL6

• Pricing: ₹12.61 lakh
• Fitting: Factory-fitted CNG

The XL6 is Maruti's premium 6-seater MPV, sold through NEXA, and CNG is available only on the Zeta trim, making it the only CNG-and-MPV combination in Maruti's lineup today. It runs the 1.5 litre K15C engine with a 5-speed manual gearbox; the 6-speed automatic offered on petrol Zeta variants isn't available once you choose CNG. The cabin layout, seating and equipment carry over largely unchanged from the petrol Zeta, aside from the drivetrain swap. It undercuts the Grand Vitara CNG by about ₹0.4 lakh while still offering three rows of seating, which is a genuine point of difference for larger families comparing these five cars.

Features:

• 2nd-row captain seats with one-touch recline and slide

• 3rd-row 50:50 split-fold seating

• Automatic climate control

• Android Auto and Apple CarPlay connectivity

• Suzuki Connect telematics

• 6 airbags, ABS with EBD and Brake Assist, ESP with hill-hold assist

• Engine: 86.63 bhp, 121.5 Nm.

• Mileage: 26.23 km/kg.

• Boot space: 209 litres with all three rows up (petrol figure; no CNG-specific figure published), extending to 550 litres with the 3rd row folded.

• Transmission: 5-speed manual only.

• Warranty: 3 years/100,000 km standard, extendable up to 6 years/160,000 km.

5. Maruti Grand Vitara

• Pricing: ₹13.00 lakh
• Fitting: Factory-fitted CNG

The Grand Vitara is Maruti's flagship compact SUV, and its CNG version was pulled from sale for a period before returning in May 2026 on the Delta trim at a revised price. It uses the same 1.5-litre CNG-tuned engine found across Maruti's other CNG models, paired with a 5-speed manual gearbox. CNG is offered on the mid-rung Delta trim, so the ventilated seats, 9-inch touchscreen and wireless charging of the petrol Zeta don't carry over, and neither do the panoramic sunroof, head-up display and 360-degree camera. At ₹13.00 lakh, it's the most expensive car here, aimed at buyers who want the largest Maruti CNG SUV rather than the longest feature list.

Features:

• 7-inch touchscreen with Android Auto and Apple CarPlay

• Cruise control

• Automatic climate control with rear AC vents

• Clarion audio system

• 6 airbags, ESC, hill-hold assist, ABS with EBD, reverse parking camera

• Engine: 88 PS, 121.5 Nm.

• Mileage: 26.6 km/kg.

• Boot space: 373 litres on petrol. A CNG-specific figure hasn't been published.

• Transmission: 5-speed manual only.

• Warranty: 3 years/100,000 km standard, extendable up to 6 years/160,000 km.

Conclusion

All five are manual-only, so none of them solve the automatic-plus-CNG gap; that combination isn't available anywhere in the current Maruti lineup. Beyond that, the choice comes down to body style and boot space. The Baleno and Fronx are the cheapest way in and return the best mileage. The Victoris is the only one that doesn't give up boot space for the CNG tank. The XL6 is the only 6-seater. The Grand Vitara is the priciest, adding cruise control and a reverse camera over the cheaper trims here.

FAQs

Do any of these CNG cars come with an automatic transmission?

No. All five, the Baleno, Fronx, Victoris, XL6 and Grand Vitara, are 5-speed manual only on CNG.

Does the CNG tank reduce boot space on these cars?

Only the Victoris is confirmed not to lose boot space, thanks to its underbody CNG tank. Maruti hasn't published CNG-specific boot figures for the other four, so the exact impact isn't confirmed, though a boot-mounted CNG cylinder conventionally takes up some cargo space.

Which is the cheapest CNG car in this list?

The Maruti Fronx, at ₹7.89 lakh ex-showroom for the Sigma CNG variant, just below the Baleno's ₹7.92 lakh.

Which of these has the most seats?

The Maruti XL6, a 6-seater MPV with 2nd-row captain seats and a 3rd row.
