The 2026 Maruti Baleno facelift’s CNG variant carries an official ARAI-certified mileage of 30.61 km/kg. Some pre-launch reports and leaks had speculated a figure as high as 33.5 to 35 km/kg, but Maruti Suzuki’s confirmed post-launch number for the CNG version is 30.61 km/kg, making it one of the most fuel-efficient CNG hatchbacks in its segment. Petrol variants return 22.35 km/l (manual) to 22.94 km/l (AMT).
What Is the Actual CNG Mileage of the Baleno Facelift 2026?
Maruti Suzuki officially launched the facelifted Baleno in India at a starting price of Rs 6.10 lakh (ex-showroom). At launch, the company confirmed the CNG variant’s fuel efficiency at 30.61 km/kg, tested and certified by ARAI (Automotive Research Association of India). This figure applies to the factory-fitted S-CNG kit paired with the updated engine lineup.
For buyers who came across claims of 33 km/kg, 34.5 km/kg, or even 35 km/kg, it’s worth clarifying that those numbers originated from pre-launch leaks and projections published before the official unveiling. Once Maruti Suzuki confirmed the final ARAI numbers at launch, the certified CNG mileage settled at 30.61 km/kg, which remains an excellent figure for a factory-fitted CNG hatchback.
Why Did Early Reports Predict Higher CNG Mileage
Before the official launch, several automotive outlets published leaked specifications suggesting the new 1.2-litre three-cylinder engine, combined with a lighter CNG tank setup and updated tuning, could push CNG efficiency beyond 33 km/kg, with some leaks pointing toward 34.5 km/kg on automatic variants. These were based on internal projections and testing mule data rather than final ARAI certification. As is common with pre-launch coverage, initial estimates are often optimistic compared to the officially homologated figures released at launch.
Engine and Powertrain Behind the CNG Mileage Figure
The 2026 Baleno facelift moves to a new 1.2-litre three-cylinder petrol engine shared with the Swift and Dzire, replacing the earlier four-cylinder K-Series unit. In CNG guise, this engine is tuned to produce around 77.5 hp and 98.5 Nm of torque, a slight step down from pure petrol output to accommodate the CNG combustion characteristics. This new engine, combined with Suzuki’s lighter platform and Dual VVT technology, is what enables the 30.61 km/kg efficiency rating.
For the first time in the Baleno’s history, the CNG variant is also available with an AMT (automated manual transmission) option, in addition to the standard 5-speed manual gearbox. This addresses a long-standing gap where CNG buyers previously had to choose manual transmission only.

Note: Manufacturers occasionally issue variant-specific mileage updates after launch. Always confirm the latest ARAI figure for your specific variant with your nearest Maruti Suzuki Arena or Nexa dealership before purchase.
How CNG Mileage Compares to Real-World Driving
ARAI mileage figures are recorded under controlled laboratory conditions and rarely match real-world performance exactly. Based on owner-reported data for the outgoing Baleno CNG, which uses a similar underlying platform, real-world CNG mileage typically ranges between 26 and 28 km/kg in mixed city and highway driving, with highway-only runs at a steady 80 to 90 km/h occasionally crossing 28 km/kg. City traffic, frequent idling, and air-conditioner usage can bring this down closer to 22 to 25 km/kg.
Buyers should treat the ARAI figure as a benchmark for comparison between models rather than a guaranteed real-world outcome.
Why the Baleno CNG’s Mileage Matters for Buyers
Fuel cost remains one of the biggest ongoing expenses for hatchback owners in India, and CNG has become the preferred option for buyers who drive high monthly distances, particularly for ride-hailing, daily office commutes, or intercity travel. At current CNG prices, a mileage of around 30 km/kg translates into meaningfully lower running costs compared to the petrol variant, often cutting fuel expenses by 40 to 50 percent per kilometre.
This is also why the CNG variant has historically accounted for a significant share of Baleno sales in metro cities with strong CNG station coverage, such as Delhi NCR, Mumbai, and Ahmedabad.
Other Updates Alongside the Mileage Improvement
The mileage figures are only part of a broader update in the 2026 facelift. The car also gets a new front fascia with reworked headlights and DRLs, a repositioned Suzuki badge, a redesigned grille and bumper, a 9-inch SmartPlay Pro+ infotainment touchscreen with an Arkamys-tuned sound system, rear AC vents, an auto-dimming inside rearview mirror, and a Level 2 ADAS suite on higher trims. Safety has also improved, with the facelifted Baleno securing a 4-star Bharat NCAP rating for both adult and child occupant protection.

What is the ARAI mileage of the Baleno CNG AMT variant? Maruti Suzuki’s official post-launch figures list the CNG variant’s mileage at 30.61 km/kg. Some pre-launch leaks suggested the CNG-AMT combination could reach closer to 34.5 km/kg, but this was not confirmed at launch.
Does the Baleno facelift CNG come with an automatic gearbox? Yes. For the first time, the Baleno CNG variant is available with an AMT gearbox in addition to the standard 5-speed manual.
How does the Baleno CNG mileage compare to its petrol variant? The petrol variant returns 22.35 km/l (manual) to 22.94 km/l (AMT), while the CNG variant returns 30.61 km/kg, making CNG the significantly more economical choice for high-mileage drivers.
What is the real-world mileage of the Baleno CNG, as opposed to the ARAI figure? Real-world CNG mileage for the Baleno platform typically falls between 26 and 28 km/kg in mixed driving conditions, based on owner-reported data, slightly lower than the ARAI-certified 30.61 km/kg.
