Maruti Suzuki Dzire Mileage Comparison: Petrol vs CNG

The Maruti Suzuki Dzire is one of India’s top-selling compact sedans, praised for its elegant design, spacious cabin, and excellent fuel efficiency. It comes equipped with a 1.2-litre petrol engine, providing both petrol and CNG fuel options to cater to varied driving requirements. It is built to provide you with excellent Maruti Suzuki Dzire mileage in all fuel cases.

The petrol model is available with both manual and AMT (automatic) transmissions, whereas the CNG model is offered only in manual transmission. The vehicle’s versatility makes it a rational option for both city and highway drivers.

In this comparison, we’ll focus on one of the most critical decision-making factors: mileage. We’ll break down the official ARAI ratings, compare them with real-world figures, and see which fuel type offers the best balance between performance and cost savings. 

Read on to explore the Maruti Dzire Petrol vs CNG mileage comparison in detail.

Maruti Dzire ARAI Mileage Figures

Official ARAI-certified mileage for the Dzire across all engine and transmission options is:

Maruti Dzire Real-World Mileage vs ARAI Mileage

While ARAI mileage is calculated under ideal lab conditions, real-world driving presents more variables. In city use, the petrol manual Dzire achieves 20–22 km/l, and the AMT petrol manages 19–21 km/l. 

The CNG model achieves approximately 28–30 km/kg in city driving, and on highways, it comes very close to its rated figure of 33.73 km/kg. Factors causing ARAI and real-world mileage to differ are:

• Driving Style: Aggressive driving, characterised by hard braking and acceleration, consumes more fuel. Smooth, gradual inputs on the accelerator and brake can be used to maintain efficiency more effectively.
• Traffic Conditions: Traffic is less efficient for both petrol and CNG. Longer idling time in traffic conditions causes the engine to burn more fuel without covering much distance.
• Load & AC Use: Additional passengers and constant AC usage reduce mileage. An excess load on the engine consumes additional power and, therefore, more fuel.
• Maintenance: Regular maintenance, including filter cleanliness and correctly serviced tyre pressure, helps maintain mileage at its best. A well-serviced car gets you closer to the fuel ratings it advertises.

For the majority of buyers, the Dzire’s fuel economy is among the class leaders, while the CNG model is popular for its economical running costs.

Maruti Dzire Fuel Efficiency Comparison: Petrol vs CNG

From the perspective of fuel efficiency, the Maruti Dzire’s petrol and CNG versions cater to the needs of various customers. The petrol version is a compromise between power and fuel efficiency, and is both highway and city-friendly. 

The CNG version is positioned as the most cost-effective option and caters to high-mileage customers looking to minimise running costs. In actual use, however, the two differ more noticeably in urban settings, where slow speeds and stop-and-go traffic can significantly impact consumption.

Maruti Dzire City Fuel Efficiency Comparison

For urban driving, the petrol version of the Dzire offers good fuel efficiency, but is hindered by lower efficiency in stop-and-go traffic situations. The AMT petrol version offers slightly higher fuel consumption compared to the manual version due to its transmission engineering. 

The CNG version is significantly more cost-effective for daily city driving, particularly in areas with heavy traffic. The prime reasons for the variation are:

• Fuel Features: CNG works well at low speeds, providing improved mileage in traffic. It’s an intelligent choice for city commuters who experience daily traffic congestion.
• Engine Tuning: The economy-tuned Dzire CNG results in fewer revs under low-speed conditions, minimising wasteful fuel burning.
• Traffic Conditions: Petrol engines consume more fuel during repeated acceleration, whereas CNG engines are better suited for constant, low-speed traffic.
• Idle Efficiency Time: CNG consumes less fuel during extended idling, resulting in better performance during traffic.
• Heat Control: Petrol engines can lose efficiency from excessive heat in stop-and-go traffic, but CNG engines have more balanced operating temperatures, which improves fuel economy.

Maruti Dzire Highway Fuel Efficiency Comparison

Dzire petrol models on highways offer great mileage when driven at a consistent pace at medium speeds. The manual petrol variant should have better mileage compared to the AMT, as it provides more direct power delivery. 

The CNG model also performs well for highway driving, but has a marginally lower overtaking ability due to its lower output. The parameters that affect highway mileage are:

• Cruising Efficiency: Petrol engines are efficient at steady higher speeds, but CNG is still more economical per kilometre, therefore cost-effective on long routes.
• Load and Air-Conditioning Consumption: Heavy loads and frequent AC usage lower efficiency in both, but the impact is more substantial in the CNG variant.
• Driving Habits: Smooth acceleration and uniform speed buildup maximise efficiency in both fuels, while sudden alternations of speed or hard braking maximise mileage.
• Altitude and Terrain: Petrol versions negotiate hills and rolling roads more easily with greater power output, whereas CNG versions can need more downshifting to keep pace.
• Availability of Fuel and Refuelling Points: Petrol is readily available on highways because it is instantly accessible, whereas CNG drivers must make route adjustments due to the limited number of refuelling points, which impacts overall travel comfort and efficiency.

Maruti Dzire Fuel Cost Comparison: Petrol vs CNG

Understanding fuel costs is essential when deciding between the petrol and CNG variants of the Maruti Dzire. 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.

Note: Fuel expense is approximated using the average petrol price of ₹84/litre and ₹50/kg CNG. Actual prices vary by location. The CNG Dzire’s running cost is almost half that of the petrol version, making it the economical choice for high-mileage drivers.

Maruti Dzire Mileage vs Competitors

Comparing the Maruti Dzire’s mileage with that of some of its closest rivals provides insight into its fuel efficiency. Here’s a look at official mileage figures for petrol and CNG variants (wherever applicable):

The Dzire stands out for its exceptional fuel efficiency in both petrol and CNG trims, particularly when compared to competitors that either don’t offer CNG or have lower efficiency ratings.

Summary

The Maruti Dzire CNG version is the most cost-effective option for running, making it ideal for low-budget, high-mileage drivers. Its factory-installed CNG system provides excellent fuel efficiency without compromising cabin space, comfort, or accessories. 

For those who value outright performance and ease of refuelling, the petrol version remains a dependable choice, thanks to its wide fuel availability and slightly better acceleration. Your ideal pick between petrol and CNG will depend on your daily travel distance, access to CNG filling stations, and performance needs. 

Additionally, both versions maintain the Dzire’s reputation for reliability, low maintenance costs, and substantial resale value, ensuring peace of mind for owners. Whether you prioritise savings or speed, the Dzire lineup offers a well-balanced solution for a variety of driving preferences.
