There are two new factory-fitted CNG cars below ₹5 lakh ex-showroom in the evidence checked on 12 November 2026: the Maruti Suzuki S-Presso LXi (O) CNG at ₹4,64,400 and the Maruti Suzuki Alto K10 LXi (O) CNG at ₹4,84,400. The S-Presso is the cheaper entry point, while the Alto K10 has the slightly higher published claimed efficiency (33.40 km/kg versus 32.73 km/kg). Both use a 1.0-litre engine and five-speed manual transmission. These are Delhi ex-showroom figures, not on-road budgets; registration, insurance, taxes and local charges can take the final bill well above ₹5 lakh.
Use the shortlist below as a starting point, then obtain an itemised quote from an authorised dealer in your city and confirm CNG availability, waiting time and the exact equipment of the variant offered.

Which CNG car is under 5 lakh in India?
The reviewed 2026 evidence identifies only the S-Presso LXi (O) CNG and Alto K10 LXi (O) CNG as new, factory-fitted CNG variants below ₹5 lakh ex-showroom. The qualifying price is for the specific CNG trim, not the starting price of the petrol range. A petrol model advertised below ₹5 lakh does not automatically have a CNG version below that ceiling.

The S-Presso LXi (O) CNG is the price leader at ₹4,64,400 ex-showroom Delhi, according to the 2026 price compilation. The Alto K10 LXi (O) CNG is ₹4,84,400 on Maruti Suzuki’s current price page and in the same compilation. Autocar India’s broader guide gives CNG-trim ranges of roughly ₹4.62–5.12 lakh for the S-Presso and ₹4.82–5.32 lakh for the Alto K10, which reflects the fact that each model has more than one CNG trim and that displayed prices can vary by source, date and location. See the 2026 CNG price compilation, the current Alto K10 price page and Autocar India’s under-₹5-lakh list for the source figures.
What is the cheapest CNG car in India?
Among the new factory-fitted options identified here, the Maruti Suzuki S-Presso LXi (O) CNG is the cheapest, at ₹4,64,400 ex-showroom Delhi. That makes it the logical first quote to request when the purchase price is the overriding constraint.
“Cheapest” does not mean cheapest to own in every city. Your on-road price, local CNG rate, annual distance, insurance premium, service access, financing cost and resale conditions determine the total cost. A small difference in published efficiency may not offset a higher purchase price if your annual mileage is low or your local CNG station is inconvenient.
How does the S-Presso LXi (O) CNG compare?
The S-Presso is the lower-cost entry into a new CNG hatchback. Its qualifying LXi (O) CNG variant is listed at ₹4,64,400 ex-showroom Delhi, and Autocar India lists a 1.0-litre engine, five-speed manual gearbox and claimed efficiency of 32.73 km/kg.
Why choose the S-Presso
- Lowest entry price: it starts ₹20,000 below the Alto K10 LXi (O) CNG on the cited prices.
- Simple decision: if you have a hard ex-showroom ceiling and both cars are available locally, it is the only one of the two that leaves more headroom before registration and insurance are added.
- Cabin character: Autocar describes the S-Presso as airy inside, which may appeal to buyers who value an upright, open-feeling cabin.
Trade-offs to consider
Autocar characterises the S-Presso’s light build as a weakness. That is an editorial observation, not an instrumented crash or safety result, so it should not be converted into a broad safety conclusion. Sit in the actual car, check the seating position and inspect the standard equipment list for the exact LXi (O) CNG vehicle offered by the dealer.
The published 32.73 km/kg figure is a claimed comparison number. Traffic, payload, tyre pressures, air-conditioning use, route gradient, driving style and the condition of the CNG system all affect consumption. Use the figure for a consistent paper comparison, not as a promise of what your fuel receipts will show.

Why choose the Alto K10
- Higher published claimed efficiency: 33.40 km/kg is 0.67 km/kg above the S-Presso’s 32.73 km/kg in Autocar’s comparison.
- Broader CNG range: Autocar lists both LXi (O) and VXi (O) CNG trims. Maruti’s price page lists the VXi (O) CNG at ₹5,34,400, so the better-equipped version is outside a strict ₹5-lakh ex-showroom limit.
- Standard equipment noted by Autocar: the publication says six airbags are standard in the CNG model. Confirm the equipment on the invoice and latest brochure because specifications can change by model year or market.
- Town-focused response: Autocar describes the Alto K10 CNG as having pep for town use, while also noting that its ride is less settled at higher speeds.
Trade-offs to consider
The Alto K10 costs more at the qualifying entry point, and selecting the VXi (O) CNG pushes the ex-showroom price above ₹5 lakh. The slightly better claimed efficiency does not establish a lower total ownership cost: you need your annual kilometres, local CNG price and actual on-road quotes to calculate that.
Autocar’s ride and performance comments are published editorial impressions, not measurements made for this article. Treat them as prompts for a dealer drive and route check rather than as universal verdicts.
What is the price difference between the two cars?
On the cited entry-variant prices, the Alto K10 LXi (O) CNG is ₹20,000 more than the S-Presso LXi (O) CNG:
| Variant | Ex-showroom price | Difference versus S-Presso |
|---|---|---|
| S-Presso LXi (O) CNG | ₹4,64,400 (Delhi figure in the 2026 compilation) | — |
| Alto K10 LXi (O) CNG | ₹4,84,400 | ₹20,000 more |
Prices checked against the cited sources in November 2026. Maruti Suzuki states that the price and schemes prevailing at the time of invoice or bill apply, so a displayed figure is not a locked transaction price.
That ₹20,000 gap is only the start. Registration charges, road tax, insurance, handling-related line items where lawful, accessories and finance costs are location- and buyer-specific. Ask both dealers for the same written breakdown so you compare like with like.
Is ₹5 lakh enough to buy one of these cars on the road?
No. ₹5 lakh is an ex-showroom ceiling in this comparison. The on-road total normally includes registration and road tax, insurance and other local charges, so it will be higher and can differ substantially between states and cities.

- 100% Satisfaction: Our products have quality assurance, if you have questions or are not satisfied after receiving the product, don't worry, please contact us as soon as possible, we provide after-sales service.
- Choose the exact variant: write “S-Presso LXi (O) CNG” or “Alto K10 LXi (O) CNG” on the request. Do not accept a petrol base-price quote as a CNG quote.
- Request a location-specific, itemised quotation: ask for ex-showroom price, registration or road-tax line, insurance, mandatory fees and any optional accessories as separate entries.
- Check the validity date: prices, schemes and taxes can change before invoicing. Maruti’s own price-page note says the price and schemes prevailing at invoice or bill time apply; read the current wording on the quote.
- Compare insurance on equal cover: check policy period, insurer, add-ons and insured-declared value rather than comparing only the headline premium.
- Remove unwanted extras: ask the dealer to mark optional accessories and service packages clearly. Keep them out of the comparison unless you genuinely want them.
Because no source in the available data establishes a nationwide on-road number, it would be misleading to publish one as if it applied to every buyer.
Which has better mileage: S-Presso CNG or Alto K10 CNG?
The Alto K10 has the higher published claimed figure in Autocar India’s 2026 guide: 33.40 km/kg versus 32.73 km/kg for the S-Presso. The difference is 0.67 km/kg on that source’s comparison.
Those are certified or claimed figures, not real-world test results. To estimate your own running cost, use:
Estimated annual CNG cost = annual kilometres ÷ expected km/kg × your local CNG price per kg
Free tools Windows power users keep installed
One-click scans. No signup required.
For a fair decision, keep the same annual distance and local fuel price for both cars, then test several realistic efficiency assumptions rather than using the headline number as a guarantee. Include petrol use during cold starts or when CNG is unavailable, because your route may not mirror the certification cycle.
Do not substitute Maruti’s older launch-release figure of 33.85 km/kg for the Alto K10 for the current comparison without noting the source and configuration difference. The 33.40 km/kg figure is the one used by Autocar’s 2026 guide for this comparison; the older figure refers to an earlier configuration.
What equipment and practicality should you check?
The sources support a few useful distinctions, but they do not provide a complete, current feature-by-feature equipment sheet for both entry variants. Confirm the exact car in writing before paying a booking amount.

Transmission and engine
Both shortlisted cars are 1.0-litre-class CNG hatchbacks with five-speed manual gearboxes in the compared variants. The Alto K10 price page specifies a 998cc engine, manual transmission and S-CNG. Readers who require an automatic should not assume one is available near this budget.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Safety equipment
Autocar says six airbags are standard in the Alto K10 CNG model. That statement should be checked against the latest variant brochure and the vehicle identification details on your quotation. The available data does not establish an independent comparative safety rating for these exact variants, so neither car should be declared universally safer from the information here.
Cabin and luggage needs
Autocar calls the S-Presso’s cabin airy, while its comments on the Alto K10 focus on town-use response and high-speed ride composure. Neither source supplies a consistent luggage-capacity measurement for this comparison. Take the items you regularly carry—child seats, work bags, a folded stroller or a cylinder-related travel kit—to the dealership and check the usable space yourself.
CNG access and service
A factory-fitted system is useful only if you can refuel and maintain it conveniently. Map the CNG stations on your normal commute and longer routes, ask the dealer about the nearest authorised service outlet, and confirm whether the exact variant is in stock or subject to a waiting period. The supplied sources do not establish current station coverage, dealer stock or waiting times across India.
Can I get an automatic CNG car for under ₹5 lakh?
Not in the reviewed 2026 price compilation. The cheapest CNG automatic listed there is the Tata Tiago Pure AMT at ₹7,12,990, far above this article’s ceiling. The two sub-₹5-lakh options identified here are manual hatchbacks.

Use this decision checklist:
- Budget: Can your on-road quote stay within the amount you can actually finance or pay?
- Distance: Will you drive enough annual kilometres for CNG’s running-cost advantage to matter?
- Refuelling: Is a dependable station on your regular route, and can you tolerate queues or detours?
- Variant: Are the safety and convenience features you need included in LXi (O), or would the higher trim push the price beyond your limit?
- Use case: Will the cabin and luggage space handle your passengers and routine loads?
- Support: Is an authorised service centre accessible, and is the dealer offering the exact car without an uncertain wait?
- Quote quality: Have you compared two itemised, same-date quotations rather than two advertised starting prices?
What should you verify before booking?
- Variant name and fuel system: the booking form should identify the factory-fitted CNG variant, not a petrol car with an aftermarket conversion.
- Price date and city: record the ex-showroom location and the date the quote was generated.
- On-road line items: obtain registration, insurance and every fee separately.
- Included equipment: ask for the latest brochure or variant sheet and match it to the vehicle identification number when the car arrives.
- Delivery timing: get the expected delivery window and the consequences if the price changes before invoicing in writing.
- Refuelling and service: identify nearby CNG stations and the authorised workshop you would use.
- Inspection: before registration, check the fuel-system labels, tyres, body panels, odometer and all promised accessories.
How we picked these CNG cars
The shortlist is limited to new, factory-fitted CNG variants that the supplied 2026 evidence places below ₹5 lakh ex-showroom. We compared the exact CNG-trim price—not a petrol model’s starting price—along with the published claimed efficiency, engine and transmission information, and the variant and ownership caveats reported by the cited sources. We did not rank either car on real-world mileage, crash performance, reliability, dealer stock, waiting time or on-road cost because the source set does not establish those factors consistently across India.
What is the final verdict?
The Maruti Suzuki S-Presso LXi (O) CNG is the answer to “what is the cheapest new CNG car under ₹5 lakh in India?” on the reviewed figures, at ₹4,64,400 ex-showroom Delhi. The Maruti Suzuki Alto K10 LXi (O) CNG is the alternative at ₹4,84,400, with a slightly higher published claimed efficiency of 33.40 km/kg. Neither price is an on-road total, and neither mileage figure predicts every driver’s fuel consumption.

Frequently Asked Questions
Is Alto K10 CNG available under ₹5 lakh?
Yes. The LXi (O) CNG is listed at ₹4,84,400 ex-showroom in the cited November 2026 sources. The VXi (O) CNG is listed at ₹5,34,400, so it does not meet a strict ₹5-lakh ex-showroom limit.
What is the on-road price of S-Presso CNG?
The available data does not establish one national on-road price. Registration taxes, insurance and other charges vary by state and buyer, so request a dated, itemised quotation from a local authorised dealer.
Does the Alto K10’s 33.40 km/kg mean it will always use less CNG?
No. It is Autocar India’s published claimed figure for the current comparison, not a guarantee. Traffic, load, air-conditioning, tyre pressure, route and driving style can change actual consumption.
Quick wins for a faster PC:
Scan for outdated or missing drivers - takes under a minuteDriver Scan →Clear out junk files and repair common Windows errorsFree Scan →Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Are these cars available with an automatic gearbox?
The two sub-₹5-lakh variants covered here use five-speed manual transmissions. The 2026 compilation lists the cheapest CNG automatic at ₹7,12,990, so an automatic requirement calls for a substantially higher budget.
Should I use the older 33.85 km/kg Alto K10 figure when budgeting?
Not without qualification. Maruti’s older launch release reported 33.85 km/kg for an earlier configuration, while Autocar’s 2026 guide lists 33.40 km/kg for its current comparison; use the latter for like-for-like budgeting and treat both as claimed figures.
