Maruti Celerio Mileage Comparison: Petrol vs CNG (2026)

The Maruti Celerio is a highly practical hatchback ideal for city commuters. It offers exceptional fuel economy and everyday comfort. You can choose between petrol and factory-fitted CNG fuel options. The petrol engine gets a five-speed manual or AMT automatic transmission. The CNG version comes exclusively with a five-speed manual gearbox. This Maruti Celerio mileage comparison matters for your daily running costs. Buyers wanting convenience often prefer the petrol automatic variant. Budget-conscious drivers focus on the excellent fuel efficiency of the CNG model.

Variant-Wise Price Difference

Before we proceed with the Maruti Celerio mileage comparison, we must understand the costs. You pay a slight premium for the CNG option over the standard petrol. The CNG option is available on the VXI variant. Let us look at the ex-showroom price difference.

There is a typical premium for the CNG factory fitment. You pay an extra Rs. 82,000 for the VXI CNG variant.

Maruti Celerio ARAI Mileage Figures

Here are the lab-tested figures for the Maruti Celerio mileage.

Disclaimer: Celerio ARAI mileage is not equivalent to the real-world average. While ARAI figures are tested under laboratory conditions, real-road driving provides varying statistics.

Maruti Celerio Mileage vs Competitors

The Tata Tiago petrol delivers a lower 19.01 km/l petrol average. This is compared to the Maruti WagonR and Celerio. The Celerio achieves a much higher 25.24 km/l petrol figure. The Celerio and WagonR also offer impressive factory-fitted CNG options.

If cabin space is just as important to you as fuel efficiency, the Maruti Wagon R mileage comparison highlights how the tall-boy hatchback balances practicality with impressive economy.

Maruti Celerio Real-World Fuel-Efficiency (City vs Highway)

Below is the real-world average of the Maruti Celerio in normal conditions.

In city driving conditions, the Celerio petrol manual typically delivers excellent numbers. It gives an average of around 17 to 19 km/l. The CNG manual returns a significantly higher 26 to 28 km/kg. On the highway, the gap continues to remain substantial. The petrol manual offers approximately 21 to 23 km/l. The CNG variant stretches further with an impressive 30 to 32 km/kg. 

Real-world numbers differ from ARAI figures. Lab tests exclude traffic and air conditioning. City traffic impacts petrol efficiency due to constant idling. Smooth driving styles significantly improve highway fuel efficiency.

Rolling resistance also plays a huge part in fuel consumption, which is why adhering to the exact Maruti Suzuki Celerio tyre pressure is essential.

Celerio Petrol vs Celerio CNG Comparison: Performance

Beyond Celerio fuel efficiency, we must compare the engine performance specifications. Here is how the petrol and CNG models match up:

The real-world drivability difference is noticeable during highway overtakes. Petrol engines are less load sensitive when fully occupied. You will feel a power drop in CNG mode. This drop requires more frequent gear changes on steep inclines.

Petrol vs CNG Comparison: Cost

Celerio running cost

To understand the true running cost difference, we must use real figures. We need the real-world average of the Maruti Celerio, not ARAI figures.

For calculation purposes:

• Petrol price assumed at Rs. 100 per litre.

• CNG price assumed at Rs. 80 per kg.

   

When you factor in realistic driving conditions, the difference becomes substantial. The CNG variant of the Celerio costs nearly half per kilometre. Your running cost with the Maruti Celerio petrol is roughly Rs. 5.26. The Celerio CNG running cost drops to just around Rs. 2.76. Maintenance is slightly higher for CNG due to spark plug replacements. However, the CNG version remains significantly more economical for high-mileage users.

Monthly & 5-Year Fuel Cost Projection

Let us assume a realistic scenario of driving 1,500 km monthly. This will help us find your total fuel expenses with the Celerio.

The savings with CNG are massive over a five-year period. You save roughly Rs. 3,750 every single month. You will recover the upfront Rs. 82,000 premium quickly. It takes just about 22 months to cover this difference. After that, you enjoy pure savings on your daily commutes.

Practical Ownership Tradeoffs

Whether you are buying a new or a used Maruti Celerio, here are the things you need to consider before deciding between the powertrain options:

Boot Space Impact

The CNG tank significantly reduces boot capacity. You can only accommodate soft bags with limited luggage flexibility.

Variant Limitation

CNG is available in the VXI and ZXI variants. You miss top-tier premium features found in the ZXI Plus.

Refuelling Convenience

CNG infrastructure in India is still expanding. Long queues at CNG stations are common in metro cities.

Maintenance & Reliability

CNG cars may require more frequent spark plug replacements. However, factory-fitted CNG kits from Maruti are reliable and safe.

Resale Value

Both petrol and CNG variants enjoy strong resale demand.
