Engine Specifications and Claimed Efficiency
The Brezza S-CNG is powered by a 1.5-litre naturally aspirated petrol engine. In CNG mode, it develops 88 hp and 121.5 Nm of torque. The engine is paired with a manual transmission.
Maruti Suzuki claims fuel efficiency of 26.9 km/kg for the Brezza S-CNG. Among the XUV 3XO ZNG, Brezza S-CNG and Nexon iCNG, this is the highest claimed figure stated in the supplied specifications.
For commuters covering long distances regularly, fuel efficiency can make a meaningful difference to the overall ownership cost. However, buyers should remember that claimed mileage figures are not guaranteed real-world results. Congested roads, frequent acceleration, air-conditioning use and vehicle load can influence actual consumption.
Why Boot Space Matters
The Brezza S-CNG’s 328-litre luggage capacity makes it particularly relevant for households that use their vehicle for office commutes, shopping and weekend journeys. Keeping the main luggage compartment relatively unobstructed can make it easier to load bags and organise everyday items.
Its naturally aspirated engine also reflects a different performance approach from the turbocharged units used by the XUV 3XO ZNG and Nexon iCNG. Buyers should evaluate engine response, transmission behaviour and comfort during a test drive rather than relying on mileage figures alone.
The Brezza S-CNG is therefore worth considering for buyers who place a high priority on boot practicality, claimed fuel economy and the convenience of a CNG-powered SUV.
Tata Nexon iCNG: Twin Cylinders and 321 Litres of Boot Space
The Tata Nexon iCNG is another strong contender for buyers looking for a CNG SUV with useful luggage capacity. It offers 321 litres of boot space through Tata’s twin-cylinder CNG technology.
This capacity is 51 litres greater than the 270-litre figure stated for the Mahindra XUV 3XO ZNG. Although the difference alone does not determine which vehicle is more practical, it gives prospective buyers a useful starting point when comparing their luggage-carrying abilities.
Engine and Transmission
The Nexon iCNG uses a 1.2-litre turbo-petrol engine that produces 100 hp and 170 Nm of torque in CNG mode. It is paired with a six-speed manual gearbox.
Its turbocharged configuration gives it a different engine character from the naturally aspirated Brezza S-CNG and Victoris S-CNG. Nevertheless, performance should be assessed in the context of the vehicle’s weight, intended usage and driving conditions.
Tata Motors claims fuel efficiency of 24 km/kg for the Nexon iCNG. While this is lower than the stated figures for the Brezza S-CNG and Victoris S-CNG, the Nexon offers its own combination of engine specifications, packaging and equipment.

The Nexon iCNG, meanwhile, combines a 321-litre boot with a turbocharged engine and a stated starting price of approximately Rs. 8.35 lakh. However, prices, variant availability and equipment should be confirmed with the respective manufacturers or dealerships before making a purchase decision.
How Twin-Cylinder Technology Is Changing CNG Cars
One of the most significant developments in the Indian CNG passenger vehicle market is the adoption of twin-cylinder technology. Traditionally, a large CNG cylinder could occupy a substantial part of the luggage compartment, limiting the amount of cargo a vehicle could carry.
Twin-cylinder systems divide the gas storage arrangement between two cylinders, allowing manufacturers to make more efficient use of the available space. Models such as the Mahindra XUV 3XO ZNG and Tata Nexon iCNG use this approach to retain usable luggage capacity.
However, the final boot space depends on the vehicle’s platform, the dimensions and positioning of the cylinders, and the overall packaging of the CNG system. Twin-cylinder technology does not automatically mean that every CNG model will have a larger boot than every petrol variant.
Underbody tank placement offers another solution. The Maruti Suzuki Brezza S-CNG and Victoris S-CNG illustrate how positioning the tank beneath the vehicle can help preserve the main luggage compartment.
For customers, these developments mean that choosing a CNG vehicle no longer necessarily requires sacrificing most of the boot space. Nevertheless, buyers should inspect the actual luggage compartment and check whether it accommodates their usual travel bags.
What Buyers Should Consider Before Purchasing a CNG SUV
Boot space is an important consideration, but it should not be the only factor influencing a purchase decision. Buyers should evaluate several aspects before selecting a CNG-powered SUV.
Real-World Fuel Efficiency
Claimed mileage is useful for comparing vehicles under specified testing conditions, but actual fuel efficiency depends on driving habits, traffic, road conditions, vehicle load and maintenance.
Customers who frequently drive in congested urban traffic should consider their typical journeys when estimating running costs. A test drive and feedback from existing owners may also help provide a more realistic picture of everyday performance.
Luggage Capacity and Boot Dimensions
A higher boot-capacity figure does not always guarantee that a vehicle will accommodate every type of suitcase. The shape of the luggage area, loading height and available width can be equally important.
Families who regularly travel with multiple suitcases should check the usable dimensions rather than relying solely on the published litre figure. It is also worth checking whether the rear seats fold down and how that affects the available cargo area.
Engine Performance and Transmission
The four models differ in their engine configurations and power outputs. The XUV 3XO ZNG and Nexon iCNG use turbocharged engines, whereas the Brezza S-CNG and Victoris S-CNG use naturally aspirated engines.
Buyers should assess acceleration, drivability, gearbox operation and performance with passengers on board. These factors can be especially relevant for those who frequently drive on highways or travel through hilly areas.
Purchase Price and Ownership Costs
The initial purchase price is only one part of the overall cost of ownership. Buyers should also consider insurance, scheduled servicing, warranty coverage, fuel expenses and the availability of authorised service centres.
A vehicle with a higher initial price may suit some customers better if it offers the features and practicality they need. Conversely, buyers who primarily commute short distances may place greater importance on the upfront cost and everyday convenience.
CNG Refuelling Availability
Access to CNG stations can significantly influence the convenience of owning a CNG vehicle. Prospective buyers should check the availability of refuelling stations near their home, workplace and regular travel routes.
Those who frequently undertake long-distance journeys should also plan around refuelling availability. Depending on the destination, carrying a suitable petrol option as part of the vehicle’s dual-fuel capability may provide additional flexibility.
Safety and Manufacturer Specifications
Customers should review the safety equipment, variant-specific features and official specifications before purchasing. They should also follow the manufacturer’s recommendations for servicing the CNG system and maintaining the vehicle.
The placement of the CNG cylinders, the vehicle’s approved configuration and compliance with applicable safety requirements are important considerations. Any inspection or maintenance involving the gas storage system should be carried out by qualified personnel.
Which CNG Car Offers the Best Combination of Boot Space and Mileage?
The best choice ultimately depends on the buyer’s priorities.
The Maruti Suzuki Brezza S-CNG stands out for its stated 328-litre boot capacity and claimed fuel efficiency of 26.9 km/kg. It is worth considering for customers who want to retain a relatively spacious luggage compartment while benefiting from CNG running costs.
The Maruti Suzuki Victoris S-CNG offers 320 litres of boot space and the highest claimed mileage in this comparison, at 27.02 km/kg. Its underbody tank layout may appeal to buyers who prefer to keep the main luggage area relatively unobstructed.
The Tata Nexon iCNG offers 321 litres of boot space, a turbocharged engine and a stated price range starting at approximately Rs. 8.35 lakh. It could be relevant to buyers looking for a combination of luggage practicality and turbocharged performance.
The Mahindra XUV 3XO ZNG, with its 270-litre boot and claimed 24.7 km/kg efficiency, takes a different approach by combining a twin-cylinder CNG setup with a turbocharged engine producing 111 hp in CNG mode. Buyers who prioritise its engine specifications may find it worth considering, although its stated boot capacity is lower than those of the other three models.
No single vehicle will suit every buyer. The final decision should account for the budget, luggage requirements, driving conditions, engine preferences and access to CNG refuelling.
The growing availability of CNG-powered SUVs with improved luggage packaging is making the segment more practical for Indian buyers. Features such as twin-cylinder CNG systems and underbody-mounted tanks are helping manufacturers address one of the traditional limitations of CNG vehicles.
Among the models covered in this comparison, the Maruti Suzuki Brezza S-CNG offers the largest stated boot capacity at 328 litres, while the Maruti Suzuki Victoris S-CNG leads in claimed fuel efficiency at 27.02 km/kg. The Tata Nexon iCNG provides 321 litres of luggage space, while the Mahindra XUV 3XO ZNG combines a twin-cylinder arrangement with a turbocharged engine.
