Maruti Celerio ARAI Mileage Figures
Official ARAI-certified mileage for the Celerio across all engine and transmission options is:
| Engine & Transmission | ARAI Mileage (km/l) |
| Petrol – Manual | 25.24 km/l |
| Petrol – Automatic | 26.68 km/l |
| CNG – Manual | 34.43 km/kg |
Maruti Celerio Real-World Mileage vs ARAI Mileage
While ARAI returns are obtained under theoretical test conditions, real-world driving conditions yield mixed results. Under city driving, the petrol manual achieves approximately 23 km/l, while the AMT petrol achieves 19–20 km/l. Under highway driving, the petrol manual is capable of achieving 26 km/l, while the AMT is capable of delivering approximately 20 km/l.
The CNG version achieves approximately 32 km/kg in urban riding and comes very close to its advertised 34 km/kg highway mileage.
A few aspects that affect the variance between ARAI and real-world mileage are:
- Driving Style: Rapid acceleration and hard braking come at the expense of fuel efficiency. Smooth, progressive inputs to the accelerator and brake pedal can be made to yield more efficiency.
- Traffic Conditions: Traffic conditions are not conducive to fuel-efficient driving for CNG and petrol vehicles. Excessive idling time during traffic conditions causes the engine to consume more fuel for a shorter distance covered.
- Load & AC Use: More passengers and frequent AC usage lower mileage. Unnecessary loading on the engine consumes extra power and thus fuel.
- Maintenance: Keeping the tyre pressure at optimal levels, maintaining clean air filters, and servicing the car timely helps ensure maximum mileage. A properly serviced vehicle helps you get closer to the ARAI fuel figures.
The fuel economy of the Celerio ranks among the top in its class for most customers, and the CNG option is in high demand due to its low operating expenses.
Maruti Celerio Fuel Efficiency Comparison: Petrol vs CNG
When it comes to fuel economy, the Maruti Celerio, available in both petrol and CNG variants, is suitable for two categories of drivers. The petrol variant is a balanced blend of performance and frugality, catering to both city driving and weekend getaways.
The CNG variant, however, is for those seeking to minimize running expenses as much as possible, particularly on a day-to-day, high-mileage basis.
In actual usage conditions, the two would differ more clearly in urban driving, with constant stops, low speeds, and short runs making a significant difference to mileage.
Maruti Celerio City Fuel Efficiency Comparison
In city traffic conditions, the petrol Celerio excels in terms of mileage but inevitably suffers due to the repeated braking and acceleration associated with city driving. The AMT variant offers convenience at the cost of being marginally less fuel-efficient than the manual variant, due to the nature of power delivery.
Meanwhile, the CNG variant is better suited for daily commutes in city traffic due to its lower running cost per kilometre.
The primary reasons behind the variation are:
- Fuel Flexibility: CNG excels in low-speed driving, providing uniform mileage to those who are forever stuck in congested traffic or take short runs. It is therefore highly beneficial to ride-hailing services and urban driving commuters.
- Engine Management: The Celerio CNG calibration is biased towards economy by maintaining lower revs in crawling traffic conditions to minimise wasteful fuel consumption. This optimises the driving range between refills without trading smoothness.
- Stop-Start Efficiency: Petrol cars consume more fuel due to repeated acceleration during stop-and-go traffic. In this regard, CNG variants tend to perform better. This is also strongly observed in congested traffic during peak hours in urban areas.
- Fuel Consumption While Idling: While driving through protracted red lights or at traffic jams, CNG burns less fuel compared to petrol, which is one of the benefits of city driving. Such minor savings, accumulated over time, eventually result in a tremendous cost advantage.
- Thermal Stability: CNG engines maintain more stable temperatures during stop-and-go travel, contributing to improved long-term efficiency. This also lowers wear on some engine components during extended city driving.
Maruti Celerio Highway Fuel Efficiency Comparison
The petrol Celerio showcases its virtues on the highway with spirited performance and its ability to maintain high mileage at constant cruise speeds. The manual trim generally outperforms the AMT in terms of efficiency due to direct control over gear changes.
Meanwhile, the CNG model remains at a reasonable price per kilometre but occasionally becomes somewhat unresponsive during fast overtaking manoeuvres or steep hill climbs.
Highway mileage criteria are as follows:
- Constant-Speed Performance: Petrol variants are designed for constant higher speeds, although CNG still offers the lower fuel cost for long-distance users. CNG is thus a low-cost option for economically viable intercity commuting.
- Passenger & Luggage Load: Additional weight and consistent use of AC decrease efficiency in both, albeit a bit more for the CNG model. Planning lighter loads for travel will help maximise fuel consumption.
- Driving Discipline: Maintaining a constant speed and avoiding sudden acceleration or braking boosts efficiency for both models. This also enhances comfort for long drives.
- Road Gradient & Altitude: Petrol versions perform better on hilly roads or gradient slopes due to their increased power. However, CNG variants will need to downshift to keep the pace. This can add marginally to travel time on upward roads.
- Refuelling Convenience: Petrol remains the most convenient fuel for refuelling anywhere, while CNG customers need to preplan because the availability of filling stations along highways is low. For frequent highway users, preplanning CNG refills is obligatory.
Maruti Celerio Fuel Cost Comparison: Petrol vs CNG
Understanding fuel costs is essential when deciding between the petrol and CNG variants of the Maruti Celerio. Let’s compare the running expenses based on a typical monthly driving of 1500 km and a few other aspects to help you gauge which option fits your budget better.
| Aspect | Petrol | CNG |
| Monthly Running Distance | 1500 km | 1500 km |
| Monthly Fuel Use | ~60 litres | ~45 kg |
| Avg. Monthly Fuel Cost* | ₹5,040 | ₹2,250 |
| Avg. Yearly Fuel Cost | ₹60,480 | ₹27,000 |
| 5-Year Fuel Cost | ₹3,02,400 | ₹1,35,000 |
Note: Fuel expense is approximated based on the average petrol price of ₹84/litre and the CNG price of ₹50/kg. Prices vary by location.
With almost half the running cost, the CNG version is the more economical choice for frequent, long-distance drivers. However, the petrol variant still offers more flexibility, quicker refuelling, and better performance in varied driving conditions.
