Maruti Brezza Mileage Comparison: Petrol vs CNG (2026)

The Maruti Brezza is a popular compact SUV offering a commanding driving stance and premium features. You can choose between refined petrol and factory-fitted CNG fuel options. The petrol engine gets a five-speed manual or a six-speed torque converter automatic transmission. The CNG version comes exclusively with a five-speed manual gearbox. This Maruti Brezza mileage comparison matters for your long-term daily running costs. Buyers wanting driving 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 Suzuki Brezza mileage comparison, it is important to understand the price premium. The factory-fitted CNG option is available across four variants. You can choose between the LXi, VXi, ZXi, and ZXi Dual Tone CNG models. 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. 91,000 for the VXi CNG variant.

Maruti Brezza ARAI Mileage Figures

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

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

Maruti Brezza Mileage vs Competitors

The Hyundai Venue delivers a higher 20.99 km/l petrol average compared to the Brezza. The Toyota Taisor achieves an impressive 22.80 km/l petrol average. The Brezza offers a factory-fitted CNG option with an excellent 25.51 km/kg claimed efficiency.

If you are exploring the pre-owned market for older models, the Maruti Vitara Brezza mileage comparison highlights how its renowned 1.3-litre diesel engine achieved an incredible 24.3 km/l during its prime.

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

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

• Real-world numbers differ from ARAI figures because lab tests exclude traffic and air conditioning.
• City traffic impacts petrol efficiency due to constant idling and frequent gear shifts.
• Smooth driving styles significantly improve the highway Maruti Brezza fuel efficiency.

• To ensure your vehicle runs smoothly, maintaining the right Maruti Suzuki Brezza tyre pressure is important to obtain the right mileage.

   

Brezza Petrol vs CNG: Performance Comparison

Beyond Brezza fuel efficiency, here is how the performance specs compare between the models.

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

Petrol vs CNG: Cost Comparison

Brezza running cost

To understand the true running cost difference, we must use the Maruti Brezza 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 substantial. The CNG variant of the Brezza costs nearly half per kilometre compared to petrol. Your running cost with the Maruti Brezza petrol is roughly Rs. 6.66 per kilometre. The Brezza CNG running cost drops to just around Rs. 3.63 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. 4,555 every single month on fuel. You will recover the upfront Rs. 91,000 premium relatively quickly. It takes just about 20 months to cover this difference. After that, you enjoy pure savings on your daily 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 traffic jams. Frequent braking negatively impacts the average 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 highway manoeuvres.

Practical Ownership Tradeoffs

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

• Boot Space Impact

   

The 55-litre CNG cylinder significantly reduces the generous 328-litre boot capacity. You can only accommodate soft bags with limited luggage flexibility.

• Feature Availability Differences

   

CNG is available across four variants, including the well-equipped ZXi. You get premium features like an electric sunroof and alloy wheels in CNG.

• Refuelling Network

CNG infrastructure in India is still expanding across rural highways. Long queues at CNG stations are common in metro citie,s which wastes time.

• Maintenance Perception

   

CNG cars may require more frequent spark plug replacements during routine servicing. However, Maruti factory-fitted CNG kits are highly reliable and extremely safe.

• Resale Trends

   

Both petrol and CNG variants enjoy strong resale demand in the used car market.

Brezza Petrol vs CNG: 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
