Hyundai Bayon CNG launches January 2027 at an expected starting price of ~₹11.20 lakh (ex-showroom), directly rivalling the Maruti Victoris CNG and Baleno CNG with a detuned 1.5-litre engine and underbody tank.
Hyundai Bayon CNG Launching January 2027 in India: Expected Price, Mileage & How It Compares to Maruti Baleno CNG
Hyundai has confirmed a January 2027 launch date for the Bayon CNG — a bi-fuel petrol-CNG variant of its recently launched mid-size SUV — with an expected starting price of approximately ₹11.20 lakh (ex-showroom), making it the brand's first model longer than 4,000 mm to carry a factory-fitted CNG powertrain in India.
The Bayon CNG enters a segment that Maruti Suzuki has long dominated through the Baleno CNG and, more recently, the Victoris CNG. Spy shots confirmed by Autocar India and GaadiWaadi show road-testing in what appears to be its final phase, suggesting the January timeline is realistic rather than aspirational.
How Does the Bayon CNG Stack Up Against Rivals at a Glance?
Before diving into the details, here is a side-by-side comparison of the Hyundai Bayon CNG against the Maruti Suzuki Baleno CNG and the Maruti Suzuki Victoris CNG — the two most relevant factory-fitted CNG alternatives in this price band.
| Specification | Hyundai Bayon CNG (Expected) | Maruti Suzuki Baleno CNG | Maruti Suzuki Victoris CNG |
|---|---|---|---|
| Segment | Mid-size SUV (4.2 m) | Premium Hatchback (3.99 m) | Mid-size SUV (4.39 m) |
| Engine | 1.5L NA Petrol (detuned for CNG) | 1.2L Dual Jet (CNG) | 1.5L NA Petrol (CNG) |
| Petrol Output | 115 hp / 144 Nm | ~90 hp / 113 Nm | ~103 hp / 137 Nm |
| CNG Output | Lower than petrol (exact TBC) | ~77 hp (CNG mode) | Lower than petrol (exact TBC) |
| Gearbox | 6-speed MT (CVT TBC) | 5-speed MT only | 5-speed MT only |
| Boot Space | 505 litres (underbody tank) | ~318 litres (reduced in CNG) | Unchanged (underbody tank) |
| ARAI Mileage (CNG) | TBC (manufacturer claim pending) | ~30.61 km/kg (ARAI claim) | TBC (manufacturer claim pending) |
| Expected Price (ex-showroom) | ~₹11.20 lakh (starting) | ₹7.49–₹9.33 lakh | ₹11.55–₹14.67 lakh |
| Spare Wheel | Likely tyre mobility kit only | Standard spare wheel | Standard spare wheel |
| 6 Airbags Standard | Yes (all variants) | 6 airbags (select variants) | 6 airbags (select variants) |
Bayon CNG figures are expected/estimated based on confirmed and reported details. Baleno CNG and Victoris CNG prices and specs are current ex-showroom figures. ARAI mileage figures are manufacturer claims.
What Engine Will the Bayon CNG Use?
The Bayon CNG is a bi-fuel petrol-CNG variant, meaning it can run on either compressed natural gas or petrol and switch between the two via a dedicated toggle switch near the engine start/stop button on the dashboard.
The powertrain is expected to be a modified version of the petrol Bayon's 1.5-litre four-cylinder naturally aspirated multi-point fuel injection (MPFI) engine — the same unit that powers the Hyundai Creta, tuned in the petrol Bayon to produce 115 hp at 6,300 rpm and 144 Nm of torque at 4,500 rpm. In CNG mode, output will be lower, as is standard practice with bi-fuel CNG conversions — the compressed gas has a lower energy density than petrol, which typically results in a 10–15% reduction in peak power.
Hyundai has not yet published official CNG-mode output figures. Treat any specific horsepower numbers for the CNG variant as estimates until Hyundai releases the technical specification sheet closer to launch.
A 6-speed manual gearbox is almost certain to be the sole option at launch. The petrol Bayon offers a CVT (which Hyundai calls an IVT — Intelligent Variable Transmission), but whether a CVT will be available with the CNG variant remains unconfirmed. Autocar India notes that it "remains to be seen" if an automatic will be paired with the CNG powertrain. For context, the Maruti Baleno CNG and Victoris CNG are both manual-only, so a CNG-automatic combination would be a genuine differentiator if Hyundai manages it.
What Is the Expected Mileage of the Bayon CNG?
The Bayon CNG's ARAI-certified mileage figure has not been published yet — Hyundai will release this number at or before the January 2027 launch. Context from comparable vehicles, however, provides a reasonable range to expect.
The Maruti Baleno CNG, which uses a smaller 1.2-litre engine, returns an ARAI-claimed 30.61 km/kg — a figure that is difficult to replicate in real-world city driving, where 22–25 km/kg is more typical. The Bayon CNG's larger 1.5-litre engine and heavier SUV body (the Bayon weighs more than the Baleno) will likely result in a lower ARAI claim, possibly in the 25–28 km/kg range, though this is speculative until Hyundai confirms the number.
The petrol Bayon CVT returns an ARAI-claimed 18.6 km/l — a manufacturer claim under controlled test conditions, not a real-world guarantee. CNG variants typically offer a significant per-kilometre running cost advantage over petrol even with a lower efficiency figure in km/kg, because CNG is priced substantially lower than petrol in most Indian cities.
What Is the Expected Price of the Bayon CNG?
The Bayon CNG is expected to start at approximately ₹11.20 lakh (ex-showroom), according to GaadiWaadi's report. For reference, the petrol Bayon's price range is ₹10.00–₹18.15 lakh (ex-showroom), so the CNG premium over an equivalent petrol trim is likely to be in the ₹80,000–₹1.20 lakh range — consistent with what Hyundai and Maruti charge for CNG variants of other models.
Hyundai is expected to offer the Bayon CNG in multiple trims, targeting both budget-conscious buyers and those willing to pay for a feature-loaded CNG SUV. The Maruti Victoris CNG, which is the most direct size-for-size rival, is priced at ₹11.55–₹14.67 lakh (ex-showroom), so the Bayon CNG's entry point would undercut the Victoris CNG's base price if the ₹11.20 lakh estimate proves accurate.
The Maruti Baleno CNG, at ₹7.49–₹9.33 lakh (ex-showroom), occupies a different market position — it is a premium hatchback, not an SUV, and competes on a lower price plane. Buyers primarily motivated by CNG running economics and not committed to the SUV form factor will naturally compare the two, especially in metros where CNG infrastructure is well-developed.
How Does the Boot Space and Practicality Compare?
Boot space is one area where the Bayon CNG is expected to hold a genuine advantage over the Baleno CNG. The Bayon CNG is likely to feature an underbody CNG tank — the same approach used by the Maruti Victoris CNG — which means the boot space remains unchanged from the petrol variant at 505 litres. That is a significant number for a mid-size SUV and is measured using the VDA 215 method with a tyre mobility kit.
The Maruti Baleno CNG uses a boot-mounted CNG cylinder, which reduces usable boot space from the petrol variant's already-modest figure. This represents a real-world disadvantage for families or buyers who carry luggage regularly.
The trade-off with the Bayon CNG's underbody tank layout, as GaadiWaadi reports, is the likely absence of a spare wheel. The petrol Bayon equips its base trim with a tyre mobility kit and all other trims with a 15-inch spare wheel. The Bayon CNG may only offer a tyre mobility kit across the entire line-up — a compromise that buyers in areas with limited roadside assistance should factor into their decision. The Baleno CNG retains a spare wheel, which is a practical advantage in this specific regard.
What Features Will the Bayon CNG Carry Over From the Petrol?
The Bayon CNG is defined as a powertrain variant of the existing Bayon, not a stripped-down budget model. This means the feature set is expected to largely mirror what the petrol Bayon offers at equivalent trim levels.
The petrol Bayon, as Times of India reports, comes with dual 12.3-inch displays (instrument cluster + infotainment), ventilated front seats, 8-way power-adjustable driver's seat, panoramic sunroof, wireless charging and Type-C USB ports, ambient lighting (crashpad and door trim), generative AI voice assistant (powered by Perplexity) and SoundHound AI voice technology, Bluelink connected-car technology with OTA updates, 6 airbags as standard across all variants, SmartSense Level 2 Pro ADAS with 23 features (higher variants), 360-degree camera system (higher variants), and 8-speaker Bose sound system (higher variants).
The Hyundai Bayon official page also highlights the H-edge LED DRLs, dual LED projector headlamps, and a dashcam as key features. The Bayon is built on Hyundai's Global K enhanced platform, engineered to meet five-star Indian crash-test safety standards, with Bharat NCAP results expected by end of 2026.
How many of these features carry over to the CNG variants will depend on which trims Hyundai makes available with the CNG powertrain. If Hyundai follows the Maruti/Toyota approach of restricting CNG to lower-spec trims, buyers will have to choose between CNG economy and top-tier features. If Hyundai offers CNG across most or all trims — which Autocar India flags as a possibility — it would be a more aggressive market play.
The Baleno CNG, for comparison, is available in mid-range trims (Delta+ and Zeta+) and does not offer the top-spec Alpha trim in CNG guise, which means buyers miss out on features like a sunroof and some connected-car tech.
Why Is This Launch Significant for Hyundai India?
This launch represents a segment milestone: the Bayon CNG will be the largest Hyundai India model — at 4.2 metres — to offer a factory-fitted CNG option. Hyundai's CNG portfolio has historically been limited to sub-4-metre vehicles. Crossing the 4-metre threshold with a CNG powertrain signals Hyundai's intent to compete in the growing mid-size CNG SUV space, which Maruti Suzuki has largely owned through the Victoris CNG.
It is also a volume play. GaadiWaadi notes that Hyundai has set a combined annual sales target of 2.5 lakh units for the Bayon and Creta. CNG variants typically broaden a model's appeal in Tier-2 and Tier-3 cities where CNG infrastructure has expanded significantly, and among fleet-adjacent private buyers who prioritise running costs. Adding a CNG variant is, in effect, a volume multiplier — Hyundai's own data from the Aura CNG and Grand i10 Nios CNG supports this pattern.
The Bayon itself was launched at ₹10 lakh (ex-showroom) for the base HX2 manual, positioned between the Venue and Creta. The petrol CVT tops out at ₹18.15 lakh. A CNG variant starting at ₹11.20 lakh would sit in the sweet spot of the Bayon range — above the entry-level petrol but well below the feature-loaded CVT variants — and could attract buyers who find the Venue too small but the Creta too expensive in CNG form (the Creta does not currently offer a CNG variant).
How Does the Bayon CNG Compare to the Maruti Baleno CNG Specifically?
The Maruti Baleno CNG is a factory-fitted bi-fuel CNG variant of Maruti's best-selling premium hatchback, available in Delta+ and Zeta+ trims with a 1.2-litre Dual Jet engine producing approximately 77 hp in CNG mode and an ARAI-claimed 30.61 km/kg. It is priced between ₹7.49 lakh and ₹9.33 lakh (ex-showroom).
The Bayon CNG is not a direct segment rival to the Baleno CNG — one is a mid-size SUV, the other a premium hatchback. But they will share buyers in practice, particularly in the CNG-first buyer cohort who prioritise running cost over form factor. Here is where the two diverge meaningfully:
Where the Bayon CNG has the edge:
- Larger body, higher ground clearance, SUV stance
- 505-litre boot (underbody tank) versus reduced boot in Baleno CNG
- More powerful engine (even in detuned CNG form, the 1.5L will likely outperform the 1.2L Baleno CNG)
- Richer feature set at equivalent price points (6 airbags standard, ADAS, larger infotainment)
- 6-speed manual versus Baleno CNG's 5-speed manual
Where the Baleno CNG has the edge:
- Significantly lower price (₹7.49–₹9.33 lakh versus an expected ₹11.20 lakh+ for the Bayon CNG)
- Higher ARAI mileage claim (30.61 km/kg versus an expected lower figure for the heavier Bayon CNG)
- Proven reliability — the Baleno CNG has been on sale for several years with an established service record
- Spare wheel retained (Bayon CNG will likely only offer a tyre mobility kit)
- Lower insurance and maintenance costs owing to lower price bracket
For buyers whose primary concern is the lowest possible per-kilometre cost and the smallest monthly EMI, the Baleno CNG remains the more rational choice. For buyers who want an SUV body, more features, and are willing to pay a premium for the Bayon's size and equipment, the Bayon CNG makes a compelling case — provided Hyundai prices it competitively against the Victoris CNG.

What Are the Key Risks and Unknowns Before Buying?
Several important details remain unconfirmed ahead of the January 2027 launch:
CNG mileage (ARAI claim): This is the single most important unknown. The Bayon CNG's ARAI-certified km/kg figure will determine whether it can match or beat the Victoris CNG on running economics. Until Hyundai publishes this number, any comparison on mileage is speculative.
Trim availability: Whether CNG will be offered across the full Bayon line-up or restricted to a few lower-spec trims will significantly affect the value. If CNG is limited to base and mid trims, buyers wanting features like ADAS or the Bose sound system will have to go petrol.
CVT availability: A CNG-automatic combination would be a first in this segment and would broaden the Bayon CNG's appeal considerably. Hyundai has not confirmed this.
Spare wheel: The likely absence of a spare wheel across the Bayon CNG line-up is a genuine concern, particularly for buyers in smaller cities or on highway routes where tyre punctures are more common and roadside assistance less accessible.
Bharat NCAP rating: The petrol Bayon's crash test result is expected by end of 2026. If it achieves a 5-star rating, it will strengthen the Bayon CNG's safety credentials significantly. Our 5-star Bharat NCAP SUVs under ₹25 lakh guide tracks these ratings as they are published.
Should You Wait for the Bayon CNG or Buy Now?
If you are in the market for a CNG mid-size SUV today, the Maruti Victoris CNG (₹11.55–₹14.67 lakh ex-showroom) is the benchmark. It offers an underbody tank, a proven CNG powertrain, and Maruti's extensive service network — the last point being a genuine advantage in smaller cities where Hyundai's dealer density is lower.
If you are specifically drawn to the Bayon's design, feature set (6 airbags standard, dual 12.3-inch screens, ADAS, AI voice assistant), and the promise of a larger engine in CNG form, waiting until January 2027 is reasonable. The gap between now and launch is short enough that you are not giving up much by holding off.
The Baleno CNG remains the right answer for buyers whose budget ceiling is under ₹10 lakh and who prioritise mileage and Maruti's service network above all else. It is a different product in a different segment, but it will draw comparisons from CNG-first buyers, and on pure running cost economics, it is hard to beat.
For buyers considering safety features alongside their CNG decision, our guide on hatchbacks with 6 airbags under ₹15 lakh covers the Baleno's safety equipment in detail.
The Bayon CNG's January 2027 launch will be one of the more consequential CNG introductions in recent years — not because CNG mid-size SUVs are new, but because Hyundai bringing its full feature arsenal to the segment will force Maruti to respond, which is ultimately good for buyers on both sides of the fence.
