For a new, factory-fitted CNG car under ₹8 lakh ex-showroom in India, the two options with variant-level prices established here are the Maruti Suzuki Alto K10 LXi (O) CNG and Celerio VXi CNG. The Alto is the lower-priced confirmed choice; the Celerio has the higher manufacturer-claimed efficiency. Maruti Suzuki also identifies the S-Presso and WagonR as S-CNG models, but their current CNG variant prices are not established consistently enough to call them confirmed under the cap.
This is not an on-road budget comparison. Registration, insurance, taxes and other local charges can take the final bill above ₹8 lakh, so obtain a written quote for your city before deciding. The figures below are manufacturer listings or claims checked in November 2026, not independent road-test results.

Which CNG cars under ₹8 lakh have a confirmed variant price?
The Alto K10 LXi (O) CNG and Celerio VXi CNG are the two models in this shortlist whose specific CNG variants have a manufacturer-listed ex-showroom price below ₹8 lakh. The threshold means the factory-fitted CNG variant’s ex-showroom price—not the model’s petrol starting price and not the total amount payable on road.

This distinction matters because manufacturer range pages often show a starting price for an entire model family. That starting figure may belong to a petrol trim, while the CNG version is a separate variant with its own price. Always match the fuel type, trim and transmission on the quote.
1. Maruti Suzuki Alto K10 LXi (O) CNG — lowest confirmed price
Maruti Suzuki lists the Alto K10 LXi (O) CNG at ₹4,84,400 ex-showroom and gives it a claimed efficiency of 33.40 km/kg. It is a manual. On the listed figures, it is the lowest-priced confirmed factory-fitted CNG option in this comparison, leaving the largest nominal gap between the ex-showroom price and an ₹8 lakh ceiling.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minuteA lower ex-showroom price does not automatically mean the lowest ownership cost. Your result will also depend on the city’s registration and insurance charges, the local CNG rate, annual kilometres, traffic conditions and the equipment you require. If you need a particular safety or convenience feature, confirm that it is included in the LXi (O) CNG trim rather than assuming it is shared with a higher petrol or CNG grade.
Check the Alto K10 CNG variant listing for the exact trim and specifications. Confirm that the quote is for LXi (O) CNG: a model’s headline starting price may refer to a different fuel or variant.
2. Maruti Suzuki Celerio VXi CNG — higher claimed efficiency
The Celerio VXi CNG is listed at ₹5,97,900 ex-showroom, with a manufacturer-claimed efficiency of 34.43 km/kg and a manual transmission. Its official claim is 1.03 km/kg higher than the Alto K10’s claim, while its listed price is ₹1,13,500 higher. That comparison identifies the relative position of the manufacturer figures; it does not prove that the Celerio will use less fuel in every owner’s traffic, route or driving style.
The Celerio may suit a buyer willing to spend more at the outset for the higher listed efficiency claim or for the equipment and packaging of that particular variant. Whether the extra ex-showroom amount is worthwhile depends on your distance travelled and actual consumption. Do not calculate a payback period from the brochure figure alone: you would need the current local CNG price, realistic fuel use and the final on-road difference.

Do the S-Presso and WagonR also fit under ₹8 lakh?
They are CNG candidates, but the evidence available here does not establish current prices for their exact CNG variants. Do not treat either as confirmed under the cap until a current variant-level quote shows that its ex-showroom price meets your budget.

Maruti Suzuki’s Arena hatchback range lists Alto K10, S-Presso, Celerio and WagonR among models with S-CNG options. A whole-model starting price is not enough to verify a CNG variant’s price. Ask the dealer to write the fuel type and trim on the quotation; otherwise a low petrol starting price can be mistaken for the CNG price.
S-Presso S-CNG
Maruti’s S-CNG technology information lists a claimed 32.73 km/kg for the S-Presso and identifies it as a manual model. That figure is lower than the listed claims for the confirmed Alto and Celerio, but efficiency claims should not be used as a ranking of real-world economy. The current S-Presso CNG variant price still needs to be checked for your city and model year before it can be placed below ₹8 lakh.

The manufacturer’s S-CNG technology page gives WagonR a claimed 34.05 km/kg, while the manufacturer’s 2025 WagonR brochure gives 33.47 km/kg. The difference may reflect a model-year, specification or document update, but the available figures do not explain it. Because the claims conflict, do not silently select the higher number for a comparison. Ask for the applicable model-year specification and retain the document supplied with your quote.
The S-CNG technology page and WagonR brochure are the relevant manufacturer references. Neither one, by itself, establishes a current city-specific CNG price.
What does “under ₹8 lakh” include?
For this shortlist, it means a CNG variant listed below ₹8 lakh ex-showroom. Ex-showroom is the manufacturer or dealer vehicle price before many location-dependent charges. It is useful for comparing variants on a common basis, but it is not the amount you transfer to complete registration and delivery.
An on-road invoice can include registration and road-tax charges, insurance, handling or documentation items where applicable, and other local costs. The exact mix and amount vary by state, city, insurer and purchase date. Therefore, a car at ₹5.97 lakh ex-showroom can still have a materially higher final bill, while a model with an unconfirmed CNG price cannot be assumed to fit merely because its petrol range starts below ₹8 lakh.
When requesting a quote, ask the dealer to identify the fuel type, trim and transmission, and to separate the ex-showroom price from registration, insurance and other charges. If your ₹8 lakh ceiling is an on-road limit, say so explicitly and ask for the total payable in writing. Compare quotes obtained on the same date and for the same variant.
How do the confirmed cars compare on price and claimed efficiency?
| Comparison point | Alto K10 LXi (O) CNG | Celerio VXi CNG |
|---|---|---|
| Listed ex-showroom price | ₹4,84,400 | ₹5,97,900 |
| Manufacturer-claimed CNG efficiency | 33.40 km/kg | 34.43 km/kg |
| Transmission identified in listing | Manual | Manual |
| Price difference | Celerio listing is ₹1,13,500 higher | |
| Efficiency difference | Celerio claim is 1.03 km/kg higher | |
The Alto is the straightforward choice for the lowest confirmed entry price. The Celerio is the alternative with the higher official claim. Neither label says which car is universally best: a buyer who wants to minimise the initial price may prefer the Alto, while someone who values the Celerio’s stated efficiency or its exact variant equipment may accept the higher price.

Both cars in this confirmed comparison use a manual transmission. If you require an automatic, do not assume that a CNG-compatible automatic variant exists or falls under the same price ceiling; verify the manufacturer’s current variant list. The figures here only establish the manual variants identified in the official listings.
How should you compare the claimed mileage?
Use the figures as manufacturer claims for the named CNG variants, not as a promise of real-world economy. The cited sources do not provide an independently tested, comparable mileage result for these cars, and the figures do not predict what a particular driver will achieve in traffic, with passengers, in air-conditioning use or on a specific route.

The S-Presso figure is 32.73 km/kg. WagonR is shown at 34.05 km/kg on the technology page and 33.47 km/kg in the 2025 brochure. Quote the source and model year whenever you repeat one of these figures.
To make your own running-cost estimate, use the structure annual kilometres ÷ actual km/kg × local CNG price per kilogram. This is a calculation method, not a claim about consumption. You still need an observed or conservatively estimated km/kg figure and the current price at stations you use. A higher official claim can reduce the theoretical fuel quantity, but it cannot establish actual savings or a payback period on its own.
Who should choose each confirmed option?
Choose the Alto K10 LXi (O) CNG when the entry price is the priority
The Alto is the clearest fit for a buyer whose first filter is the lowest confirmed ex-showroom price. Its ₹4,84,400 listing is well below the stated ceiling, and its 33.40 km/kg claim is still substantial on the manufacturer’s scale. Before booking, check that the quoted LXi (O) CNG equipment meets your needs and that the resulting on-road total remains within your real budget.
Choose the Celerio VXi CNG when the higher listed efficiency or trim matters more
The Celerio costs more at the listed ex-showroom level but carries the higher 34.43 km/kg claim among the confirmed options. It can make sense if you are comfortable with the larger initial outlay and prefer the VXi CNG specification. Validate the equipment list, waiting period, service arrangements and final city quote rather than paying more solely because one brochure number is higher.

Keep S-Presso and WagonR on the shortlist only after a current quote
S-Presso and WagonR remain relevant alternatives because Maruti lists them as S-CNG models. Their price status is unresolved here, and WagonR’s efficiency figures conflict across manufacturer documents. Treat them as models to investigate, not as confirmed sub-₹8 lakh recommendations.

Use this checklist to avoid comparing unlike prices or relying on an outdated figure:

- Confirm the exact factory-fitted CNG variant. Ask for the model, trim, fuel type and transmission in writing. Do not use a petrol model’s starting price as the CNG price.
- Check the current ex-showroom price. The prices cited above are manufacturer listings, but prices can change. Confirm the amount for your city, dealer and booking date.
- Get the full on-road quote. Request a line-by-line total and compare it with your actual ceiling. A sub-₹8 lakh ex-showroom price does not guarantee a sub-₹8 lakh on-road total.
- Verify the variant’s current specification. Check the transmission and equipment on the quoted trim. Do not assume that a feature shown in a model advertisement is included in every CNG variant.
- Check the model year and document date. This is especially important for WagonR because the technology page and 2025 brochure show different efficiency claims.
- Ask how the quoted price is held. Confirm whether the amount applies to your booking date and whether a later price revision could affect delivery. Get the dealer’s terms in writing.
- Consider refuelling practicality. The cited data do not compare local CNG-station access. Check stations on your normal commute, expected queues and whether your regular routes include reliable refuelling points.
- Plan for petrol fallback. CNG availability can vary by route and time. Understand how you will refuel when a station is closed, crowded or outside your usual area.
- Inspect the delivered car and paperwork. Ensure the invoice, registration documents and warranty paperwork name the same CNG variant you ordered.
- Compare like with like. Use the same price basis, date, fuel type and transmission when comparing Alto, Celerio, S-Presso or WagonR.
What does the manufacturer say about CNG-system safety?
Maruti Suzuki states: “Maruti Suzuki S-CNG vehicles are evaluated and tested for crashworthiness and durability with entire CNG System in place.” This is the manufacturer’s statement, not an independent crash-test result, a comparative safety rating or proof that one shortlisted model is safer than another.
Use the statement as information about the manufacturer’s testing approach, then ask for the exact variant’s current safety equipment and consult independent ratings where available. Do not turn a manufacturer statement into a claim that all four models have identical protection or that one model has won a comparative safety test.
What are the main buying pitfalls?
- Confusing a range starting price with a CNG price: the Arena range’s model-level starting figures do not verify a CNG trim.
- Treating ex-showroom as on-road: local registration, insurance and other charges can move the final bill above ₹8 lakh.
- Ranking by claimed mileage alone: official km/kg figures are not independent, comparable road-test results.
- Ignoring variant labels: Alto LXi (O) CNG and Celerio VXi CNG are specific trims, not generic model names.
- Hiding the WagonR discrepancy: 34.05 km/kg and 33.47 km/kg appear in different manufacturer documents; identify the applicable model year instead of choosing the more attractive number.
- Assuming every shortlisted price is current: S-Presso and WagonR need fresh variant-level confirmation.
- Overlooking station access: a theoretical fuel advantage is less useful if refuelling is inconvenient on your regular routes.
How we picked these options
The confirmed ranking uses the exact factory-fitted CNG variant’s manufacturer-listed ex-showroom price and claimed efficiency. The Alto K10 comes first for the lower listed price; the Celerio is the alternative with the higher listed claim. S-Presso and WagonR are identified as candidates, not ranked as confirmed under-budget choices, because current variant-level prices were not established.
This is a focused shortlist of models supported by the cited Maruti Suzuki pages and brochure, not a complete survey of every automaker’s current CNG cars in India. Prices, variants and specifications can change, so use the official page and a current dealer quotation for the final decision.
Bottom line
If your ₹8 lakh limit is ex-showroom, the Maruti Suzuki Alto K10 LXi (O) CNG is the lowest-priced confirmed option at ₹4,84,400, while the Celerio VXi CNG is listed at ₹5,97,900 and carries the higher claimed efficiency of 34.43 km/kg. S-Presso and WagonR deserve a price check but should not be labelled confirmed under the cap without a current CNG-variant quote. For any of them, compare the complete on-road total, verify the exact model year and trim, and check that CNG access fits your daily routes.

Can I compare a CNG car’s starting price with another car’s CNG price?
Only if both figures refer to the same basis and fuel-specific trim. A model’s advertised starting price can be for a petrol version, so ask for the named CNG variant’s price rather than assuming the headline figure applies.
Does an ex-showroom price below ₹8 lakh mean the on-road price will also be below ₹8 lakh?
No. Registration, insurance, taxes and other local charges can raise the final amount. Ask for a written, city-specific on-road quote for the exact CNG variant.
Recommended Free Tools
Are S-Presso and WagonR confirmed under ₹8 lakh?
Not from the price details established here. Maruti identifies both as S-CNG models, but current variant-level CNG prices were not conclusively captured. Obtain a current quote before counting either within your budget.
Why are two WagonR mileage figures shown?
Maruti’s S-CNG technology page lists 34.05 km/kg, while its 2025 WagonR brochure lists 33.47 km/kg. The documents do not resolve the difference, so confirm the applicable model-year figure instead of presenting one as universally current.
Does the listed km/kg figure tell me how much I will save?
No. A mileage claim by itself is not a savings estimate: you also need local CNG pricing, annual distance and actual consumption. Treat the figure as a manufacturer specification, not a guaranteed result or payback calculation.
Are the CNG systems independently crash-rated in this comparison?
No independent comparative crash result is established here. Maruti says its S-CNG vehicles are evaluated and tested for crashworthiness and durability with the entire CNG system in place; that remains a manufacturer statement, not an independent rating.
