Maruti Brezza CNG Underbody Tank: Full Boot Space Coming Soon
Maruti Suzuki is preparing to solve the biggest problem faced by CNG car owners in India—the lack of boot space. Recent reports and spy shots suggest that the upcoming 2026 Maruti Brezza will feature a new Underbody CNG Tank technology.
This is a major shift for Maruti Suzuki, which has so far used the traditional large cylinder placed inside the boot. With this new update, the Brezza CNG will finally offer luggage space comparable to its petrol counterpart, directly challenging the Tata Nexon CNG.
Here is everything we know about this upcoming “game-changer” update.
What is the Underbody CNG Tank Technology?
Currently, most Maruti CNG cars (like the WagonR or current Brezza) come with a massive 60-liter cylinder fitted inside the boot. This leaves almost no room for luggage.
The new Underbody CNG Tank setup moves the gas storage from the boot area to the underside of the vehicle or the spare wheel cavity.
- Placement: The tanks are likely to be mounted where the spare wheel usually sits or attached to the chassis under the floorboard.
- Result: The boot floor remains flat and usable, giving you the full 328-liters (approx.) of space for bags and suitcases.
- Spare Wheel Change: To make space for the tank, the spare wheel might be moved to the underside (if room permits) or replaced with a puncture repair kit, similar to what we see in Tata’s twin-cylinder cars.
Why is This Update Important?
For the last two years, Tata Motors has dominated the “premium CNG” market with its Twin-Cylinder technology in cars like the Nexon, Punch, and Altroz. Buyers loved that they didn’t have to compromise on luggage space.
Maruti Suzuki, despite being the market leader in CNG sales, was lagging in this specific area. By introducing an underbody tank in the Brezza, Maruti is fixing the only major complaint owners had. This makes the Brezza CNG a complete family car for long highway trips where luggage space is essential.

Expected Features & Specs
The 2026 Brezza with the underbody tank is expected to carry forward the reliable mechanicals of the current model but with added premium touches.
- Engine: 1.5-litre K15C Petrol Engine.
- Performance: Approx 87 bhp and 121.5 Nm torque (in CNG mode).
- Mileage: Expected to remain high, around 25.51 km/kg.
- Safety: The updated model is rumored to come with 6 or 7 airbags as standard and possibly Level-2 ADAS (Advanced Driver Assistance Systems) in top variants.
Launch Timeline and Price
While Maruti Suzuki has not given an official date, test mules (camouflaged cars) with this setup have been spotted testing recently.
- Expected Launch: Mid-to-Late 2026.
- Price: Expect a slight price hike of ₹20,000 to ₹30,000 over the current CNG variants due to the new engineering required for the underbody setup.
Conclusion: Should You Wait?
If you are planning to buy a CNG SUV specifically for family use and traveling, it might be worth waiting for this update. The current Brezza is an excellent car, but the lack of boot space is a dealbreaker for many. The upcoming model promises to offer the best of both worlds—Maruti’s reliability and mileage, combined with the practicality of a diesel or petrol SUV.
Frequently Asked Questions (FAQs)
Q1. Will the new Brezza CNG have a spare wheel?
It is likely that the spare wheel will be removed to make space for the underbody tank. Maruti may provide a tire puncture repair kit instead, or mount the spare wheel underneath the car if design allows.
Q2. Is the underbody tank safe?
Yes. Manufacturers use high-strength steel and conduct rigorous crash tests to ensure the tank is protected from road debris and rear-impact collisions.
Q3. Will the mileage change with the underbody tank?
No, the mileage is expected to remain similar to the current model (approx. 25 km/kg) as the engine and weight will not change drastically.
Q4. Can I retrofit an underbody tank in my old Brezza?
No. This modification requires structural changes to the chassis and floorboard, so it cannot be installed in existing models legally or safely.
Q5. Which other Maruti cars will get this technology?
After the Brezza, it is expected that the Maruti Fronx and the Grand Vitara may also receive similar boot-saving CNG updates in the future.
