The Maruti Baleno has long been one of India’s most fuel-efficient premium hatchbacks, making it a popular choice for both city commuters and highway drivers. In 2026, it continues to offer excellent efficiency across its petrol manual, AMT and factory-fitted CNG variants, with ARAI-certified mileage of up to 30.61 km/kg. In this guide, we explain the official mileage figures, expected real-world fuel economy, driving range and the factors that affect the Baleno’s efficiency in everyday driving.
Maruti Baleno Mileage at a Glance
| Variant | Transmission | Fuel | ARAI Mileage |
| Sigma, Delta, Zeta, Alpha | 5-speed MT | Petrol | 22.35 km/l |
| Delta, Zeta, Alpha | 5-speed AMT | Petrol | 22.94 km/l |
| Delta, Zeta | 5-speed MT | CNG | 30.61 km/kg |
The Baleno CNG is only offered with a 5-speed manual gearbox, while the petrol version is available with either a 5-speed manual or a 5-speed AMT. All mileage figures above are ARAI-certified and measured under standard laboratory test conditions.
Why Baleno Mileage Matters So Much to Buyers
The Baleno has earned its reputation in the premium hatchback segment by combining a spacious cabin, a refined petrol engine and excellent fuel efficiency. Since many owners use it as a daily commuter, running costs are a major deciding factor. Choosing between the petrol and CNG variants can make a noticeable difference to annual running costs.
Under the bonnet, the Baleno is powered by Maruti Suzuki’s 1.2-litre K-Series Dual Jet, Dual VVT petrol engine, paired with Idle Start Stop (ISS) technology. The system automatically switches off the engine when the car comes to a halt and restarts it as soon as you press the clutch in the manual or the brake in the AMT. This helps reduce fuel consumption, particularly during stop-and-go city traffic.
The Baleno also helps drivers monitor fuel efficiency through its multi-information display, which shows instantaneous fuel economy, average fuel economy, fuel consumption history, and Idle Start Stop performance. These readouts help drivers monitor fuel consumption and adapt their driving style for better efficiency.
ARAI vs Real-World Baleno Mileage
The 22.35 to 30.61 figures above are ARAI-certified numbers, tested in lab conditions on a fixed cycle. Your actual mileage will be lower, and how much lower depends on how and where you drive.
Based on owner reports from automotive communities such as Team-BHP, here is the typical mileage that Baleno owners report in everyday driving:
| Fuel & Transmission | Expected Real-World Mileage |
| Petrol MT (mixed) | 17–20 km/l |
| Petrol AMT (mixed) | 17–19 km/l |
| Petrol Highway | 19–22 km/l |
| CNG City | 20–23 km/kg |
| CNG Highway | 27–29 km/kg |
These are individual ownership figures, not averaged test data, so treat them as real-world reference points rather than a guarantee for your own car. Heavy traffic, AC use and driving style will pull these numbers in either direction.
Petrol MT vs AMT: Why the Mileage Barely Differs
On paper, the AMT returns a slightly higher ARAI-certified mileage than the manual (22.94 km/l versus 22.35 km/l), even though automatic cars often return slightly lower fuel economy than manuals. Maruti Suzuki’s AMT is rated to deliver a marginally higher ARAI-certified mileage during standardised testing. In everyday driving, however, the difference is very small, and many owners report similar fuel economy from both transmissions.
If your driving is mostly highway with light traffic, the difference between the two gearboxes is negligible. If you drive mostly in heavy city traffic, the manual usually edges ahead in the hands of an experienced driver.
Does Idle Start Stop Really Improve Mileage?
Yes. Idle Start Stop (ISS) is one of the Baleno’s most useful fuel-saving technologies for urban driving. Every time the vehicle comes to a complete halt, such as at a traffic signal, the engine switches off automatically to prevent unnecessary fuel consumption. It restarts instantly when you press the clutch (manual) or the brake (AMT). While the savings on any single trip are small, they add up over months of regular city driving.
Baleno CNG: How It Delivers 30.61 km/kg
The factory-fitted CNG variant is where the Baleno’s fuel efficiency really stands out. It runs on a dual inter-dependent Electronic Control Unit (ECU) setup with an intelligent injection system that manages the air-fuel ratio for both fuel modes. Two things are worth understanding here:
Power drops in CNG mode. Petrol mode makes 89.7 PS, while CNG mode makes 77.5 PS. This is normal for factory-fitted CNG systems and is the trade-off for the fuel savings.
Tank space is shared, not sacrificed entirely. The Baleno CNG retains its 37-litre petrol tank alongside a 55-litre (water equivalent) CNG cylinder. The water-equivalent figure refers to the cylinder’s physical capacity rather than the amount of CNG stored. Maruti Suzuki does not publish the exact usable quantity of CNG in kilograms, so real-world driving range can vary depending on the amount of fuel filled and operating conditions.
Maruti also builds in specific CNG safety measures on the Baleno: stainless steel pipes and joints to prevent corrosion and leakage, integrated wire harnesses to rule out short-circuiting, and a microswitch that stops the car from starting while it is being refuelled with CNG.
Fuel Tank Capacity and Driving Range by Variant
| Variant | Fuel Tank | ARAI Mileage | Approx. Driving Range |
| Petrol MT | 37 litres | 22.35 km/l | ~827 km |
| Petrol AMT | 37 litres | 22.94 km/l | ~849 km |
The Baleno CNG uses a 55-litre (water equivalent) CNG cylinder while retaining the full 37-litre petrol tank. Maruti Suzuki does not specify the exact usable quantity of CNG in kilograms, so the total driving range will vary depending on the amount of CNG filled and driving conditions.
What Affects the Baleno’s Real-World Mileage
A few habits make a bigger difference than most owners expect:
- Traffic and idling: Frequent stop-start driving is the single biggest drag on mileage, especially in petrol mode.
- AC usage: Running the AC continuously in city traffic can shave off a noticeable chunk of efficiency.
- Tyre pressure: Underinflated tyres increase rolling resistance and can quietly cost you a few percentage points of mileage.
- Driving style: Hard acceleration and late braking hurt both petrol and CNG mileage equally.
- Short trips: Frequent short journeys don’t let the engine reach efficient operating temperature, which shows up as lower reported mileage over time.
Maruti Baleno Mileage Compared to Rivals
With ARAI-certified mileage of 22.35-22.94 km/l for petrol and 30.61 km/kg for CNG, the Baleno ranks among the most fuel-efficient premium hatchbacks currently on sale in India. Its petrol efficiency is competitive with rivals such as the Hyundai i20, while its factory-fitted CNG variant remains one of the most economical options in the premium hatchback segment.
