Maruti Dzire Mileage Comparison: Petrol vs CNG (2026)

The Maruti Dzire is a highly popular compact sedan offering exceptional value for money and even a five-star safety rating with the latest generation. You can choose between refined petrol and highly efficient factory-fitted CNG fuel options. The petrol engine gets a five-speed manual or a convenient AMT automatic transmission. The CNG version comes exclusively with a five-speed manual gearbox. This Maruti Dzire mileage comparison matters deeply for your long-term daily running costs. Buyers wanting driving convenience often prefer the petrol automatic variant. Budget-conscious drivers focus strictly on the excellent fuel efficiency of the CNG model.

Variant-Wise Price Difference

Before we proceed with the Maruti Suzuki Dzire mileage comparison, you must understand the price premium. The CNG option is available on the mid-spec VXi and ZXi variants. Let us look at the ex-showroom price difference for the popular VXi trim.

There is a typical premium for the CNG factory fitment. You pay an extra Rs. 86,000 for the VXi CNG variant.

Official ARAI Mileage Figures

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

Disclaimer: ARAI = lab-tested, not road-realistic.

Car mileage vs competitors for the available engine options

The Maruti Dzire achieves a remarkably high petrol and CNG average compared to older sedans. The Dzire offers an incredibly impressive 33.73 km/kg claimed efficiency. Its closest Korean rival also puts up a strong fight for city commuters; the Hyundai Aura mileage comparison highlights a solid 20.5 km/l on petrol and a very practical 28.4 km/kg on CNG. The Honda Amaze delivers a lower 18.6 km/l petrol average compared to the Dzire. 

Real-World Mileage (City vs Highway)

Below is the real-world average of the Maruti Dzire in both city and highway conditions.

Real-world numbers differ from ARAI figures because lab tests exclude traffic and air conditioning.

• City traffic drastically impacts petrol efficiency due to constant idling and gear shifts.

• Smooth driving styles significantly improve highway Maruti Dzire fuel efficiency.

   

Performance Comparison

Beyond Dzire fuel efficiency, here is how the new Z-series engine specs compare.

The real-world drivability difference is noticeable during highway overtakes with a full passenger load. Petrol engines are slightly less load sensitive when all five seats are occupied. You will feel a noticeable power drop in CNG mode. This power drop requires more frequent gear changes on steep inclines and flyovers.

Cost Comparison

Per km running cost

To understand the true running cost difference, we must use the Maruti Dzire real-world average mileage.

For calculation purposes:

• Petrol price assumed at Rs. 100/litre

• CNG price assumed at Rs. 80/kg

   

When you factor in realistic driving conditions, the difference becomes quite substantial. The CNG variant of the Dzire costs nearly half per kilometre compared to petrol. Your running cost with the Maruti Dzire petrol is roughly Rs. 5.55 per kilometre. The Dzire CNG running cost drops to just around Rs. 3.20 per kilometre. Even after accounting for slightly higher annual maintenance, the CNG version remains significantly more economical.

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.

The savings with CNG are massive over a five-year period. You save roughly Rs. 3,525 every single month on fuel expenses. You will recover the upfront Rs. 86,000 premium relatively quickly. It takes just about 24 months to cover this specific price difference. After that, you enjoy pure savings on your daily family commutes.

City vs Highway Efficiency Difference

City Use

Stop-and-go traffic drastically lowers petrol efficiency. CNG engines use less fuel while idling in heavy urban traffic jams. Frequent braking negatively impacts the average fuel efficiency of both fuel types.

Highway Use

Consistent cruising speeds drastically improve your highway mileage. Petrol engines perform better when overtaking slow trucks easily. CNG requires you to downshift gears for quick and safe highway manoeuvres. Because under-inflated tyres drag the engine down, maintaining the right Maruti Suzuki Dzire tyre pressure is important to obtain the right mileage.

Practical Ownership Tradeoffs

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

• The CNG cylinder significantly reduces the generous 382-litre boot capacity. You can only accommodate soft bags with limited luggage flexibility. 
• The CNG option is available in VXi and ZXi trims. You miss premium features like the 360-degree camera on the top ZXi Plus. 
• CNG infrastructure in India is still expanding across rural highways. Long queues at CNG stations are common in metro cities, which wastes time. C

• CNG cars may require more frequent spark plug replacements during routine servicing.

   

Who Should Buy Which

Here is a quick summary for your buying decision.

Choose Petrol if:

• You need the absolute convenience of a smooth automatic gearbox.
• You frequently travel with heavy luggage and require maximum boot space.

• You prefer strong engine performance for effortless highway overtakes.

   

Choose CNG if:

• Your daily commute exceeds 50 kilometres in heavy stop-and-go traffic.
• You want the absolute lowest daily running costs possible for your family.
• Boot space is not your primary buying concern for daily city driving.
