How Much Does the Maruti Baleno CNG AMT Cost in India 2026? Price, Mileage and Running Cost

The Maruti Baleno CNG AMT is priced from Rs 8.32 lakh (ex-showroom) for the Delta trim and Rs 9.32 lakh for the Zeta trim, making it one of the first premium hatchbacks in India to combine a factory-fitted CNG powertrain with an automated manual transmission. Launched on 18 September 2026 alongside the Swift CNG AMT and Dzire CNG AMT, the Baleno CNG AMT claims an ARAI-certified fuel efficiency of 34.47 km/kg — 0.86 km/kg better than the existing CNG manual version.

For city commuters stuck in stop-and-go traffic who want the running-cost advantage of CNG without the fatigue of a clutch pedal, this combination is genuinely new territory in the premium hatchback segment. But it comes with a real compromise that no amount of marketing softens: the CNG cylinder lives inside the boot, leaving almost no usable luggage space.

How does the Baleno CNG AMT compare with rivals?

The table below covers the three CNG-AMT hatchbacks available in India as of September 2026. All mileage figures are manufacturer (ARAI) claims; real-world numbers will be lower.

Model	CNG Kit	Starting Price (ex-showroom)	CNG Mileage (ARAI)	Boot Space (CNG mode)	Key Weakness
Maruti Baleno CNG AMT (Delta)	Factory-fitted S-CNG	Rs 8.32 lakh	34.47 km/kg	Negligible (cylinder + spare wheel in boot)	Near-zero boot space; no underbody tank
Tata Altroz CNG AMT	Factory-fitted iCNG (twin-cylinder)	~Rs 8.00 lakh*	~28–29 km/kg*	~210 litres usable	Lower claimed mileage than Baleno
Maruti Swift CNG AMT (VXi)	Factory-fitted S-CNG	Rs 7.92 lakh	35.34 km/kg	Negligible (cylinder + spare wheel in boot)	Same boot-space penalty as Baleno
Maruti Dzire CNG AMT (VXi)	Factory-fitted S-CNG	Rs 8.53 lakh	36.47 km/kg	Negligible (cylinder + spare wheel in boot)	Sedan body, not a hatchback

The Baleno sits in the middle of Maruti's own CNG-AMT trio — more expensive than the Swift, cheaper than the Dzire, and with the lowest mileage of the three. Against the Altroz, it wins on claimed fuel efficiency by a meaningful margin but loses on boot practicality because Tata's twin-cylinder iCNG setup preserves around 210 litres of usable cargo space even with both cylinders loaded.

What engine and gearbox does the Baleno CNG AMT use?

The Baleno CNG AMT is defined as a factory-fitted S-CNG vehicle, meaning the CNG system is integrated at the manufacturing stage by Maruti Suzuki — not retrofitted by a dealer or third-party kit maker. This distinction matters for warranty: factory-fitted S-CNG cars carry Maruti's standard manufacturer warranty on both the vehicle and the CNG system, unlike dealer-fitted or aftermarket kits which can void the OEM powertrain warranty.

Under the bonnet sits the Z12E 1.2-litre, three-cylinder, naturally aspirated engine with Dual VVT (variable valve timing) and Idle Start Stop (ISS) technology. In CNG mode, it produces 69.75 PS (approximately 70 hp) and 101.8 Nm of torque. On petrol, the same engine makes 82.93 PS and 112.4 Nm — a drop of roughly 13 PS and 11 Nm that becomes noticeable on highway overtakes or steep inclines.

The gearbox is a 5-speed Auto Gear Shift (AGS) transmission — Maruti's term for its AMT unit. The clutch actuates automatically during gear changes, but the driver can also nudge the lever manually for low-speed city crawling. There is no torque converter involved, so the characteristic AMT head-nod during gear changes is present, especially at low speeds. Coming from a torque-converter automatic requires adjusted expectations.

ISS shuts the motor off at prolonged stops and restarts it quickly. Maruti claims this helps fuel economy in heavy urban traffic — a plausible assertion, though real-world Indian conditions for this specific variant have not yet been independently verified.

What is the full price list for the Baleno CNG AMT in 2026?

Maruti Suzuki revealed the complete price list on 21 September 2026. Two trims are available:

Delta CNG AMT: Rs 8.32 lakh (ex-showroom)
Zeta CNG AMT: Rs 9.32 lakh (ex-showroom)

The CNG AMT variants command a Rs 40,000 premium over the equivalent CNG manual trims. Compared to the petrol AMT variants, the CNG AMT versions cost an additional Rs 79,500. That premium buys you the CNG running-cost advantage but not any additional features — the feature set within each trim is identical to the CNG manual version.

Within Maruti's simultaneous CNG-AMT launch:

Swift CNG AMT starts at Rs 7.92 lakh
Baleno CNG AMT starts at Rs 8.32 lakh
Dzire CNG AMT starts at Rs 8.53 lakh

The Baleno's positioning as a "premium hatchback" is reflected in its price sitting above the Swift, even though the Swift actually returns better mileage (35.34 km/kg vs 34.47 km/kg). You are paying for the Baleno's larger dimensions, slightly more premium cabin feel, and the brand's premium hatchback positioning — not for better CNG efficiency.

What is the real-world running cost of the Baleno CNG AMT?

Running cost arithmetic is where the Baleno CNG AMT makes its strongest case. Using Delhi CNG prices as a reference point (approximately Rs 75 per kg as of mid-2026; verify current rates at your nearest CNG station before purchase):

On CNG (ARAI claim: 34.47 km/kg):

Cost per km = Rs 75 ÷ 34.47 = approximately Rs 2.18 per km

On petrol (Baleno petrol AMT ARAI claim: approximately 22 km/l; petrol in Delhi approximately Rs 95/litre):

Cost per km = Rs 95 ÷ 22 = approximately Rs 4.32 per km

That is a saving of roughly Rs 2.14 per km on CNG versus petrol. For a commuter covering 1,500 km per month — a reasonable urban average — the monthly saving works out to around Rs 3,200, or about Rs 38,400 per year. At that rate, the Rs 79,500 premium over the petrol AMT version pays back in roughly 25 months, assuming CNG prices and usage patterns remain stable.

These are ARAI-certified figures, and real-world CNG mileage in Indian city traffic typically runs 10–15% lower than the certified number. Adjusting for that, the Baleno CNG AMT might realistically deliver around 29–31 km/kg in mixed urban driving, which still makes the running cost math attractive compared to petrol.

CNG station density varies significantly by city. In Delhi, Mumbai, Ahmedabad, and Pune, CNG infrastructure is dense enough that range anxiety is minimal. In smaller cities or on long highway trips, planning refuelling stops becomes necessary. The Baleno CNG AMT carries a 37-litre petrol tank alongside the 55-litre (water-equivalent) CNG cylinder, so you always have petrol as a backup — the car switches automatically to petrol when CNG runs out.

How much boot space does the Baleno CNG AMT actually offer?

This is the most significant practical compromise in the Baleno CNG AMT, and it deserves an honest answer: the boot space is negligible in CNG mode. The CNG cylinder (55-litre water-equivalent capacity) sits inside the boot alongside the spare wheel, leaving almost no room for luggage.

Maruti has not adopted the underbody CNG tank layout for the Baleno — a layout that debuted with the Victoris and has since appeared in the Brezza facelift. That underbody setup preserves the full boot floor for luggage. For the Baleno, Swift, and Dzire CNG AMT variants, Maruti retained the traditional boot-mounted cylinder arrangement.

The contrast with the Tata Altroz iCNG is stark. The Altroz uses a twin-cylinder CNG setup housed in the boot but still manages approximately 210 litres of usable luggage space — enough for a couple of cabin bags or a week's worth of groceries. Tata's twin-cylinder iCNG is defined as a dual-tank CNG architecture where two smaller cylinders replace one large cylinder, reducing the individual cylinder footprint and freeing up usable floor space.

If you regularly carry luggage — weekend trips, airport runs, grocery hauls — the Baleno CNG AMT will frustrate you. For primarily urban commuting with occasional short trips and minimal luggage, the boot-space penalty is more manageable.

The Baleno's standard petrol boot capacity (without CNG) is 318 litres. In CNG mode, that number effectively drops to near zero for practical purposes. This is not a minor inconvenience — it is a fundamental change in how you use the car.

Which variants are available and what features do they include?

The Baleno CNG AMT is offered in Delta and Zeta trims only — the same trims as the CNG manual version. The top-spec Sigma and Alpha trims are not available with the CNG AMT powertrain. Buyers who want the highest feature level in the Baleno lineup cannot get it with CNG and AMT together.

The Delta trim at Rs 8.32 lakh includes:

9-inch SmartPlay Pro+ touchscreen infotainment with smartphone connectivity
Automatic climate control
Multiple airbags and ESP (Electronic Stability Program) as standard safety equipment
CNG fuel-level indicator and dedicated fuel-mode switch
Retuned suspension (compared to petrol version) to handle the CNG cylinder's additional weight

The Zeta trim at Rs 9.32 lakh adds features over the Delta — typically including a 360-degree camera, head-up display, and additional convenience features, though buyers should confirm the exact feature split at the dealership since trim-level features can vary by state.

Both trims get the same 70 hp / 102 Nm CNG output, the same 5-speed AMT, and the same 34.47 km/kg ARAI mileage claim. Maruti adjusts the spring and damper rates on all CNG variants to compensate for the heavier CNG cylinder, which helps maintain ride quality close to the petrol version's character.

How does the Baleno CNG AMT fit into Maruti's broader S-CNG strategy?

Maruti Suzuki's S-CNG sales grew 58 per cent year-on-year in the first quarter of FY2027, with July 2026 marking the company's highest-ever monthly S-CNG sales at 83,000 units. The simultaneous launch of CNG AMT variants across three models — Swift, Baleno, and Dzire — directly responds to that demand, targeting urban buyers who want CNG economics without a manual gearbox.

Until this launch, Tata Motors was the only carmaker offering an AMT option with factory-fitted CNG vehicles (the Tiago iCNG AMT, Tigor iCNG AMT, and Altroz iCNG AMT). Maruti's entry changes the competitive space significantly, given the brand's dominant market share and its existing CNG customer base.

The Baleno CNG AMT's positioning within Maruti's own lineup is interesting. The Fronx CNG occupies the compact SUV segment above the Baleno hatchback, targeting buyers who want SUV styling with CNG running costs. The Baleno CNG AMT targets buyers who prefer a traditional hatchback form factor — lower roofline, lighter kerb weight, and typically better city manoeuvrability — but still want the two-pedal convenience.

Maruti has signalled that the underbody CNG tank technology (first seen on the Victoris) will eventually filter down to more models. A Wagon R facelift test mule with an underbody CNG tank has already been spotted testing. If and when that technology reaches the Baleno, the boot-space compromise disappears — but that is a future product, not the car you can buy today.

Should you buy the Baleno CNG AMT, or wait for a rival?

The Baleno CNG AMT suits a specific buyer profile: someone who commutes primarily in a CNG-dense city, covers high monthly distances (1,200 km or more), wants automatic convenience, and can live without meaningful boot space. For that buyer, the running cost savings are real and the payback period on the premium over petrol is reasonable.

The car is less suitable if you regularly carry luggage, travel frequently on highways where CNG stations are sparse, or if you need the full boot for family use. In those scenarios, the Tata Altroz iCNG AMT's 210 litres of usable boot space makes it the more practical choice, even if its claimed mileage trails the Baleno's.

Within Maruti's own CNG-AMT lineup, the Swift CNG AMT at Rs 7.92 lakh offers better mileage (35.34 km/kg) at a lower price — the Baleno's premium over the Swift is justified only if you specifically want the Baleno's slightly larger dimensions and premium hatchback positioning. The Dzire CNG AMT at Rs 8.53 lakh offers the best mileage of the three (36.47 km/kg) but is a sedan, not a hatchback, which changes the driving character and parking dynamics.

The Baleno CNG AMT is a genuinely useful new variant in a segment that needed it. Its weaknesses — the boot-space penalty and the AMT's characteristic jerkiness at low speeds — are real and consistent across the Maruti CNG-AMT range. Its strengths — factory warranty, 34.47 km/kg ARAI claim, and the convenience of two-pedal driving with CNG economics — are equally real. Go in with clear eyes about what you are trading away, and it is a strong choice for the right buyer.
