CNG Price Crosses ₹100/kg in Ahmedabad November 2026: What Running Cost Means for Buyers

Ahmedabad CNG is now defined as a fuel priced above ₹100 per kilogram for the first time in the city's history, after Adani Total Gas raised rates by ₹2.30/kg on November 5, 2026, taking the pump price to ₹100.77/kg. Petrol in Ahmedabad simultaneously sells at ₹101.83/litre — a gap of just ₹1.06. That near-parity changes the running-cost arithmetic for every CNG car owner and prospective buyer in Gujarat.

This marks the ninth price revision Adani Total Gas has made in 2026. The cumulative net increase since January 1 stands at ₹17.79/kg, despite a ₹1.21/kg reduction at the start of the year. October's ₹4.45/kg hike and August's ₹4.00/kg increase show the pace accelerating rather than slowing.

Before diving into what this means model by model, here is a snapshot of how popular factory-fitted CNG cars compare on the numbers that matter most at ₹100.77/kg in Ahmedabad:

Model	CNG Kit	ARAI km/kg (CNG)	Cost/km at ₹100.77/kg	Ex-showroom CNG variant (approx.)	Boot space (CNG)
Maruti Dzire CNG	Factory-fitted S-CNG	33.73 km/kg	₹2.99	₹9.40–11.00 lakh	268 litres (single cylinder)
Maruti Baleno CNG	Factory-fitted S-CNG	30.61 km/kg	₹3.29	₹9.50–10.50 lakh	~170 litres (single cylinder)
Maruti Fronx CNG	Factory-fitted S-CNG	28.51 km/kg	₹3.54	₹10.00–11.50 lakh	~204 litres (single cylinder)
Tata Tiago iCNG	Factory-fitted iCNG	26.49 km/kg	₹3.80	₹7.90–9.00 lakh	~242 litres (twin cylinder)
Tata Tigor iCNG	Factory-fitted iCNG	26.49 km/kg	₹3.80	₹8.70–9.80 lakh	~316 litres (twin cylinder)
Hyundai Exter CNG	Factory-fitted	27.10 km/kg	₹3.72	₹9.00–10.50 lakh	Reduced (single cylinder)

All km/kg figures are ARAI-certified manufacturer claims; real-world mileage is typically 15–20% lower. Prices are approximate ex-showroom and vary by city and variant.

Why did CNG prices in Ahmedabad cross ₹100/kg now?

Adani Total Gas is the city gas distribution (CGD) licensee for Ahmedabad. CGD companies buy natural gas from upstream producers and the spot market, and their input costs have risen sharply in 2026 due to elevated international LNG prices and disruptions to global gas supply through the Strait of Hormuz, which have pushed India's LNG import costs higher even as domestic gas production has not kept pace with demand.

The November 5 hike of ₹2.30/kg came just 13 days after the October 23 revision of ₹4.45/kg — an unusually short interval reflecting how quickly input costs are moving. Eight of the nine 2026 revisions have been increases, with one reduction. Vadodara, also served by Adani Total Gas, has seen its CNG price rise to ₹98.95/kg — likely to cross ₹100 in the next revision cycle.

Ahmedabad's ₹100.77/kg is not the highest CNG price in India. Faridabad stands at ₹102.60/kg and Kolkata at ₹103/kg, while Thane remains significantly cheaper at ₹85.75/kg and Gurgaon at ₹92.01/kg. CNG pricing in India is city-specific, set by the local CGD licensee, which means the running-cost advantage of a CNG car varies dramatically depending on where you live and refuel.

How much has the CNG savings case weakened for Ahmedabad buyers?

The savings case for CNG is defined as the difference in per-kilometre fuel cost between CNG and petrol, multiplied by annual kilometres driven. When that gap narrows, the payback period on the premium you pay for a CNG variant stretches out.

At current Ahmedabad prices (₹100.77/kg CNG, ₹101.83/litre petrol):

Maruti Dzire CNG (ARAI: 33.73 km/kg CNG, ~22 km/l petrol):

CNG cost per km: ₹100.77 ÷ 33.73 = ₹2.99/km
Petrol cost per km: ₹101.83 ÷ 22 = ₹4.63/km
Saving per km: ₹1.64
Annual saving at 15,000 km: ₹24,600

Maruti Baleno CNG (ARAI: 30.61 km/kg CNG, ~22 km/l petrol):

CNG cost per km: ₹100.77 ÷ 30.61 = ₹3.29/km
Petrol cost per km: ₹101.83 ÷ 22 = ₹4.63/km
Saving per km: ₹1.34
Annual saving at 15,000 km: ₹20,100

Maruti Fronx CNG (ARAI: 28.51 km/kg CNG, ~21 km/l petrol):

CNG cost per km: ₹100.77 ÷ 28.51 = ₹3.54/km
Petrol cost per km: ₹101.83 ÷ 21 = ₹4.85/km
Saving per km: ₹1.31
Annual saving at 15,000 km: ₹19,650

Tata Tiago iCNG (ARAI: 26.49 km/kg CNG, ~19.8 km/l petrol):

CNG cost per km: ₹100.77 ÷ 26.49 = ₹3.80/km
Petrol cost per km: ₹101.83 ÷ 19.8 = ₹5.14/km
Saving per km: ₹1.34
Annual saving at 15,000 km: ₹20,100

These figures rely on ARAI-certified manufacturer claims. Real-world CNG mileage in city traffic typically runs 15–20% lower, which compresses the savings further. At a real-world 28 km/kg for the Dzire CNG, the cost per km rises to ₹3.60 — cutting the annual saving to around ₹15,000 at 15,000 km/year.

A Dzire CNG costs roughly ₹70,000–90,000 more than the equivalent petrol variant. At ₹24,600 annual saving (ARAI claim) or ₹15,000 (real-world estimate), the payback period is 3–6 years. That remains viable for a high-mileage user, but the math was far more compelling when CNG was at ₹82/kg in early 2026.

What does this mean specifically for Maruti S-CNG owners in Gujarat?

Maruti Suzuki's S-CNG system is a factory-fitted, sequential CNG injection system that retains the manufacturer's warranty on the engine and drivetrain — unlike dealer-fitted or aftermarket CNG kits, which typically void the OEM warranty on affected components. This advantage over the aftermarket CNG segment remains unchanged regardless of fuel price.

The Dzire CNG, Baleno CNG, and Fronx CNG are the three Maruti S-CNG models most relevant to Gujarat buyers. All three use a single-cylinder CNG tank mounted in the boot, which is the primary trade-off buyers accept: the Baleno CNG's boot shrinks to approximately 170 litres (from 318 litres in the petrol version), the Dzire CNG to 268 litres, and the Fronx CNG to around 204 litres. This effectively eliminates the ability to carry large luggage on a family road trip while running on CNG.

Power output also suffers. On CNG, the Dzire produces approximately 77 PS versus 90 PS on petrol. The Baleno CNG produces around 77 PS on CNG versus 90 PS on petrol. This trade-off is most noticeable during highway overtaking or on steep gradients.

At ₹100.77/kg, the Dzire CNG's annual saving over petrol (at 15,000 km, ARAI figures) is around ₹24,600. Over three years, that is ₹73,800 — enough to justify the CNG premium if you drive consistently and have reliable CNG access. Gujarat buyers should note that Ahmedabad has only 50 Adani CNG outlets as of November 2026. For buyers in smaller Gujarat towns or those who frequently travel on state highways, CNG station availability remains a genuine constraint that the savings calculation does not capture.

How does Tata's twin-cylinder iCNG approach compare at these prices?

Tata Motors' iCNG system, available on the Tiago and Tigor, uses two smaller CNG cylinders mounted under the boot floor rather than a single large cylinder inside the boot. This twin-cylinder configuration preserves usable boot space — the Tigor iCNG retains approximately 316 litres, comparable to its petrol sibling. The Tiago iCNG similarly loses far less boot space than the Baleno CNG.

Efficiency is the trade-off: the Tiago iCNG's ARAI claim of 26.49 km/kg is lower than the Dzire CNG's 33.73 km/kg, which at ₹100.77/kg translates to ₹3.80/km versus ₹2.99/km. Over 15,000 km annually, that is a difference of roughly ₹12,150 in fuel costs between the two cars — meaningful over a three-year ownership period.

Tata's iCNG kits are factory-fitted and warranty-backed, putting them on equal footing with Maruti S-CNG. The Tiago iCNG's lower ex-showroom price (approximately ₹7.90–9.00 lakh) versus the Baleno CNG (approximately ₹9.50–10.50 lakh) offers a different value proposition: lower upfront cost, more boot space, but higher per-km fuel cost at current Ahmedabad CNG prices.

Should you reconsider buying a CNG car in Ahmedabad right now?

The answer depends on your annual mileage and your confidence in CNG prices stabilising. Here is the three-year running cost recalculation:

Scenario: 15,000 km/year, Ahmedabad, CNG at ₹100.77/kg (current), petrol at ₹101.83/litre

Model	3-yr CNG fuel cost (ARAI)	3-yr petrol fuel cost (ARAI)	3-yr saving on CNG	CNG premium over petrol variant
Maruti Dzire CNG	₹1,34,100	₹2,08,350	₹74,250	~₹80,000
Maruti Baleno CNG	₹1,47,900	₹2,08,350	₹60,450	~₹75,000
Maruti Fronx CNG	₹1,59,300	₹2,18,250	₹58,950	~₹80,000
Tata Tiago iCNG	₹1,71,000	₹2,31,300	₹60,300	~₹60,000

All fuel costs calculated using ARAI-certified km/kg and km/l figures, which are manufacturer claims. Real-world figures will be higher. CNG premium is approximate and varies by variant.

The Dzire CNG is the only model in this group where the three-year fuel saving (₹74,250 at ARAI figures) meaningfully exceeds the CNG variant premium (approximately ₹80,000) — and only barely, and only if you drive at ARAI efficiency. At real-world mileage (say, 28 km/kg for the Dzire CNG), the three-year saving drops to around ₹55,000, which does not cover the premium.

This does not mean CNG cars are a bad buy in Ahmedabad. It means the payback period has stretched from roughly 2–3 years (when CNG was at ₹82/kg in early 2026) to 4–5 years at current prices. For buyers who plan to keep the car for 5–7 years and drive 18,000–20,000 km annually, the case still holds. For buyers who drive less than 12,000 km/year or plan to sell within three years, the numbers no longer work cleanly.

There is also the question of trajectory. Nine price increases in 2026 with a cumulative net rise of ₹17.79/kg suggest structural input cost pressures rather than temporary ones. If that pace continues into 2027, the savings case will erode further. Auto-rickshaw drivers in Ahmedabad have already approached the state government demanding a CNG subsidy, but no decision has been taken. There is no indication that Gujarat will intervene in Adani Total Gas pricing in the near term.

What are cab operators and commercial CNG users doing?

The impact on commercial operators is more immediate and more severe than on private car owners. Auto-rickshaw drivers and cab operators run far higher annual kilometres — often 60,000–80,000 km/year — which means every ₹1/kg increase in CNG adds ₹2,000–3,000 to their annual fuel bill.

Paresh Thakker, treasurer of the Gujarat Luxury Cab Owners Association, noted that higher fares could discourage bookings, particularly for longer journeys. The hike comes just ahead of the festive season — Diwali — when outstation travel demand peaks. Operators face a difficult choice: absorb the cost and compress margins, or pass it on through higher fares and risk losing customers.

For private car buyers evaluating a CNG vehicle, this commercial pressure is worth watching. If cab operators shift away from CNG or reduce their fleet, it could affect the political pressure on state governments to intervene in CNG pricing — which could work either way.

How does Ahmedabad's CNG price compare to other Indian cities?

CNG pricing in India is city-specific, set by the local city gas distribution licensee, not a nationally uniform price. A CNG car owner in Thane pays ₹85.75/kg while one in Kolkata pays ₹103/kg — a difference of ₹17.25/kg that translates to a cost-per-km difference of roughly ₹0.65/km on a car doing 26 km/kg. Over 15,000 km/year, that is ₹9,750 in additional fuel cost simply due to geography.

Current CNG prices across major cities: Thane ₹85.75/kg, Gurgaon ₹92.01/kg, Bhubaneswar ₹93.50/kg, Darjeeling ₹95/kg, Kanchipuram ₹98.50/kg, Ahmedabad ₹100.77/kg, Faridabad ₹102.60/kg, Kolkata ₹103/kg.

Ahmedabad buyers are now in the expensive half of the national CNG price spectrum. The same Maruti Dzire CNG that makes strong financial sense in Thane (cost per km: ₹85.75 ÷ 33.73 = ₹2.54/km) is a much tighter call in Ahmedabad (₹2.99/km) and barely viable in Kolkata (₹3.05/km).

What should a Gujarat buyer do before buying a CNG car today?

Run the numbers with your actual mileage, not ARAI figures. A realistic approach:

Estimate your annual kilometres honestly. If it is under 12,000 km/year, the CNG premium will not pay back within a typical ownership period at current Ahmedabad prices.
Check CNG station density on your daily route. Ahmedabad has 50 Adani outlets — adequate for city use, but thin for highway travel. If you regularly drive to Surat, Rajkot, or smaller towns, factor in the inconvenience of planning refuelling stops.
Consider the boot space trade-off before committing. The Baleno CNG's ~170-litre boot is genuinely restrictive for a family. The Tata Tigor iCNG's twin-cylinder setup preserves more boot space at the cost of lower km/kg efficiency.
Factor in the CNG variant's lower power output. On CNG, most factory-fitted cars produce 10–15% less power than on petrol. This is manageable in city traffic but noticeable on highways.
Do not assume CNG prices will stabilise. The nine revisions in 2026 suggest that input cost pressures are structural, not temporary. Build a sensitivity analysis: what does your payback period look like if CNG hits ₹110/kg by mid-2027?

For buyers who drive 18,000+ km/year and have reliable CNG access, the Dzire CNG remains the strongest value in Ahmedabad at current prices — its 33.73 km/kg ARAI claim is the highest in its segment, and its factory-fitted S-CNG system preserves the Maruti warranty. For buyers prioritising boot space over fuel efficiency, the Tata Tigor iCNG's twin-cylinder setup is worth serious consideration despite its lower km/kg rating.

For buyers who drive under 12,000 km/year or are uncertain about their tenure with the car, the petrol variant of any of these models is now a more defensible choice in Ahmedabad than it was at the start of 2026.
