Introduction
The Nissan Gravite CNG Kit is finally here, and it brings a clever engineering twist that no other sub-4-metre MPV has attempted before. Nissan Motor India launched the government-approved retrofit kit on May 4, 2026, at an introductory price of Rs 82,999, and the highlight is a segment-first twin-cylinder layout that lets the Gravite keep all three rows of seats functional even after fitment. For Indian families who want low running costs without giving up the 7-seater character that defines this MPV, the Nissan Gravite CNG Kit opens a door that simply did not exist in this price band a day ago.
CNG buyers in India have lived with one big compromise for years. Choose CNG, and your boot effectively disappears. Choose space, and you stay on petrol. Nissan has tried to bend that rule with a vertically stacked twin-cylinder system developed and quality-assured by Motozen, certified by ICAT, and offered through authorised dealerships in 60 cities across 16 states. Nissan is positioning the kit under the tagline “Smart Power with Smarter Savings”, promising significantly lower running costs per kilometre while retaining the Gravite’s modularity, comfort, and everyday usability. Below, you will find every verified detail, the technical specifications, the running-cost logic, the honest trade-offs, and the Motors77 Verdict on whether the Nissan Gravite CNG Kit earns its asking price.
What Exactly Is the Nissan Gravite CNG Kit?
The Nissan Gravite CNG Kit is a dealer-fitted, government-approved retrofitment system designed exclusively for the all-new Nissan Gravite, which was launched in India on 17 February 2026. Unlike most sub-4-metre CNG offerings that rely on a single large cylinder eating into the entire boot floor and often forcing the removal of the third row, Nissan has chosen a smarter route. The kit uses two compact 25-litre cylinders, stacked vertically inside the existing boot bay, leaving the seven-seat configuration intact for everyday family use.
This is the first time a sub-4-metre Indian MPV has been offered with a factory-endorsed twin-cylinder retrofit, which is precisely why Nissan is calling it a segment-first solution. The system is BS6.2 compliant, supports seamless switchover between petrol and CNG modes, and uses the latest Dynamic Advancer Technology calibrated specifically for the Gravite’s 1.0-litre three-cylinder engine.
“After an extremely positive reception from the customers for the Magnite CNG, we are delighted to now launch the first twin-cylinder solution in the segment for the All-New Nissan Gravite.” Mr. Saurabh Vatsa, Managing Director, Nissan Motor India
“India continues to be a strategic market for Nissan, and our focus is on bringing products and mobility solutions that are relevant, accessible and future-ready, aligned with the evolving needs of the customers. With Gravite CNG, we are extending a proven, practical solution to customers seeking a combination of family-focused space, everyday mobility, and lower running costs in key CNG markets.” Mr. Thierry Sabbagh, Divisional Vice President and President, Middle East, KSA, CIS and India, Nissan and Infiniti
Nissan Gravite CNG Kit Price and Availability
Nissan has positioned the kit aggressively to drive adoption. The introductory Rs 82,999 charge is over and above the on-road price of the chosen Gravite variant. Customers can order the installation through any authorised Nissan dealership across the 60 launch cities, either at the time of vehicle purchase or as a post-delivery upgrade.
The base Nissan Gravite is priced from Rs 5.65 lakh (Visia MT) to Rs 8.94 lakh (Tekna Launch Edition AMT) ex-showroom. With the kit factored in, the effective ex-showroom price for a manual Gravite buyer ranges roughly from Rs 6.48 lakh to Rs 9.77 lakh, before RTO and insurance. There is no separate factory-fitted CNG variant for now, which means the entire existing manual petrol line-up is upgrade-eligible at the dealer level.
For exact city-level pricing and dealership availability, Motors77 recommends checking with your nearest authorised Nissan outlet, since RTO charges, insurance, and accessory packages vary city to city.
How the Twin-Cylinder Setup Works
Most retrofit CNG kits in this segment use a single 50 to 60-litre cylinder placed flat or upright on the boot floor. That layout works for sedans and hatchbacks where the boot is purely a cargo area. In a 7-seater MPV, however, that same approach forces the manufacturer or installer to fold or remove the third row to make space for the cylinder.
The Nissan Gravite CNG Kit sidesteps this problem. Engineers at Motozen have stacked two slim 25-litre cylinders vertically, packaged within the boot bay behind the third row. The combined 50-litre water-equivalent capacity is similar to a regular single-cylinder solution, but the vertical orientation preserves the full passenger seating layout. Nissan specifically notes that the rear seat layout has been optimised to maintain passenger comfort, and that ample space remains in the third row after fitment.
Note for buyers: while passenger space across all three rows is preserved, the cargo area behind the third row is largely occupied by the twin cylinders after fitment, since this is a retrofit kit and not a factory underbody installation. If you regularly travel with seven occupants, you should plan for a roof carrier for luggage. If you usually ride with five, the third row can still be folded or removed to free up cargo room, and the cylinders remain stowed neatly behind it.
Nissan Gravite CNG Kit Technical Specifications
The technical sheet of the Nissan Gravite CNG Kit has been engineered with longevity, safety, and emission compliance in mind.
| Parameter | Specification |
|---|---|
| Cylinder Configuration | Twin-cylinder (2 x 25 litres) |
| Cylinder Orientation | Vertically stacked in boot |
| Cylinder Wall Thickness | 8.1 mm (heavy-duty) |
| Compliance | BS6.2 Sequential CNG Kit |
| Certification | ICAT-approved |
| Advancer | Dynamic Advancer Technology |
| Fuel Filling Point | Under the standard fuel lid |
| Fuel Mode Switching | Seamless petrol and CNG switchover |
| Integration Quality | Factory-finish with dedicated brackets |
| Compatible Transmission | 5-speed Manual (likely) |
The 8.1 mm cylinder thickness is notably above the regulatory minimum, and the ICAT (International Centre for Automotive Technology) approval ensures that the kit complies with Indian safety and emission norms. The under-fuel-lid filling point is a thoughtful detail as well, because it removes the need for a second flap and gives the Gravite a clean factory-fitted look.
Nissan Gravite Base Engine and Performance
To understand what the Nissan Gravite CNG Kit does to performance, it helps to first recall the petrol baseline.
| Specification | Petrol (Existing) | With CNG Kit (Indicative) |
|---|---|---|
| Engine | 1.0L, 3-cylinder, NA Petrol | Same engine, dual-fuel |
| Displacement | 999 cc | 999 cc |
| Max Power | 72 PS @ 6,250 rpm | Slightly lower in CNG mode |
| Max Torque | 96 Nm @ 3,400 to 3,600 rpm | Slightly lower in CNG mode |
| Transmission | 5-speed MT / 5-speed AMT | 5-speed MT (likely) |
| ARAI Mileage (Petrol) | 19.3 kmpl (MT) / 19.6 kmpl (AMT) | Not officially disclosed for CNG |
| Platform | CMF-A+ | CMF-A+ |
| Seating | 7 | 7 |
Nissan has not yet quoted an ARAI-certified efficiency figure or specific power output for CNG mode. As is usual with retrofit systems, expect a modest dip in peak power and torque in CNG mode, balanced against running costs that are typically 40 to 50 percent lower than petrol on a per-kilometre basis in CNG-dense markets. The kit is most likely offered only with the manual gearbox, which is the standard practice for retrofit CNG installations on AMT platforms.
Why a 7-Seater CNG MPV Matters in India
Indian buyers in the Rs 6 lakh to Rs 10 lakh band are increasingly looking at fuel choice as a long-term savings calculation. With CNG retailing far cheaper than petrol per kilometre in cities such as Delhi, Mumbai, Pune, Ahmedabad, and Lucknow, a high-usage MPV can recover the kit cost in 18 to 24 months for a typical 1,500 to 2,000 km monthly user.
Until now, the only sub-4-metre 7-seater MPV in India was the Renault Triber, and a retrofit CNG kit for the Triber existed only with a single-cylinder layout that ate into seating practicality. The Nissan Gravite CNG Kit is fundamentally different from the upcoming factory-developed Renault Triber CNG, which uses an underbody twin-tank arrangement enabled by deeper platform re-engineering. The Gravite, sharing the older CMF-A+ architecture, sticks to a boot-mounted layout but cleverly preserves seating.
For ride-share operators, large families, and rural-to-urban commuters, the proposition is simple. You get a real 7-seater that costs significantly less to run, with a manufacturer-backed kit and a 3-year warranty.
Nissan Gravite CNG Kit Running Cost Calculator: Petrol vs CNG
The buying decision usually comes down to running-cost math, so here is the apples-to-apples comparison based on May 2026 fuel prices in India.
Assumptions used:
- Petrol price: Rs 105 per litre (representative metro average)
- CNG price: Rs 80 per kg (representative metro average)
- Gravite petrol mileage: 19.3 kmpl (ARAI, MT)
- Gravite CNG mileage: approximately 22 km/kg (estimated; official ARAI figure not yet disclosed by Nissan)
Cost per Kilometre
| Mode | Fuel Price | Mileage | Cost per km |
|---|---|---|---|
| Petrol | Rs 105 / litre | 19.3 kmpl | Rs 5.44 |
| CNG | Rs 80 / kg | ~22 km/kg | Rs 3.64 |
| Saving | — | — | Rs 1.80 / km |
Monthly and Annual Savings
| Monthly Distance | Monthly Saving | Annual Saving |
|---|---|---|
| 1,000 km | Rs 1,800 | Rs 21,600 |
| 1,500 km | Rs 2,700 | Rs 32,400 |
| 2,000 km | Rs 3,600 | Rs 43,200 |
| 2,500 km | Rs 4,500 | Rs 54,000 |
| 3,000 km | Rs 5,400 | Rs 64,800 |
Break-Even on the Rs 82,999 Kit Investment
| Monthly Distance | Break-Even Time |
|---|---|
| 1,000 km | ~46 months (3.8 years) |
| 1,500 km | ~31 months (2.6 years) |
| 2,000 km | ~23 months (1.9 years) |
| 2,500 km | ~18 months (1.5 years) |
| 3,000 km | ~15 months (1.3 years) |
If you drive 2,000 km or more per month, the Nissan Gravite CNG Kit pays for itself in under two years and turns into pure savings for the rest of the ownership period. Below 1,000 km a month, the math is far less compelling, and the petrol-only Gravite remains the smarter buy.
Local-rate note: Pune CNG retails at around Rs 92.50 per kg, Mumbai at Rs 81 per kg, Delhi at Rs 77.09 per kg, and Ahmedabad at Rs 82.25 per kg as of May 2026. Higher CNG rates extend the break-even period, while lower rates accelerate it. Always recalculate using your local pump prices.
Real-World Use Cases: Who Benefits Most?
| Use Case | Suitability | Why It Works (or Does Not) |
|---|---|---|
| Family with one car used daily | ⭐⭐⭐⭐⭐ Excellent | High monthly km, full 7 seats stay usable, savings compound quickly |
| App-cab or taxi operator | ⭐⭐⭐⭐⭐ Excellent | 3,000+ km/month means payback in ~15 months, then pure profit |
| Pure city commuter (under 1,000 km/month) | ⭐⭐ Limited | Long break-even (~46 months); petrol Gravite makes more sense |
| Highway-heavy weekend driver | ⭐⭐⭐ Moderate | CNG infrastructure thins on highways; expect mixed-mode running |
| Tourist transfer or rental fleet | ⭐⭐⭐⭐ Strong | Predictable costs and 7-seater capacity ideal for short tours |
| Long-distance trips with 7 occupants and full luggage | ⭐⭐ Limited | Cargo area behind 3rd row is occupied; needs roof-rack planning |
| Buyer in Delhi, Mumbai, Pune, Ahmedabad | ⭐⭐⭐⭐⭐ Excellent | Mature CNG network plus aggressive savings per km |
| Buyer in tier-2 or tier-3 city with sparse stations | ⭐⭐⭐ Moderate | Verify CNG station density on your daily route before committing |

Nissan Gravite CNG Kit vs Rivals
| Parameter | Nissan Gravite CNG Kit | Renault Triber CNG (Retrofit) | Maruti Ertiga CNG (Factory) |
|---|---|---|---|
| Type | Dealer Retrofit | Dealer Retrofit | Factory-fitted |
| Cylinder Layout | Twin (2 x 25L), vertical, boot | Single, boot | Single, boot |
| Seating Retained | 7 | Up to 5 (third row use limited) | 7 |
| Approval | ICAT, government-approved | ICAT | OEM-fitted, ARAI |

| Engine | 1.0L NA Petrol | 1.0L NA Petrol | 1.5L NA Petrol |
| Warranty (Kit) | 3 yr / 1,00,000 km | Brand-specific | Full vehicle warranty |
The Ertiga remains the segment heavyweight thanks to a factory-fit S-CNG system, but it is a larger, costlier vehicle. Within the sub-4-metre MPV bracket, the Nissan Gravite CNG Kit is now the only option that combines a manufacturer-backed twin-cylinder retrofit with full 7-seater practicality.
Safety and Compliance
The kit carries ICAT certification, which is the standard Indian regulatory benchmark for retrofit CNG systems. The cylinders meet the IS 15490 norm with an 8.1 mm wall thickness, well above the regulatory floor, which improves crash worthiness and long-term durability. The Sequential BS6.2 compliance ensures the system meets the latest emission norms with on-board diagnostics integration, and the Dynamic Advancer Technology fine-tunes ignition timing in CNG mode to reduce knocking and protect the engine.
The base Nissan Gravite already comes with six airbags as standard, ABS with EBD, ESP, hill-hold assist, TPMS, and a rear camera, which means the safety package remains uncompromised after fitment.
Should You Buy the Nissan Gravite CNG Kit?
Direct decision guidance, no fence-sitting.
Buy It If:
- You drive 2,000 km or more per month in a CNG-dense city. Break-even arrives in under two years.
- You need a genuine 7-seater for family or commercial use and refuse to sacrifice the third row.
- You operate a taxi, ride-share, or rental fleet where every rupee saved per km translates into profit.
- You already own or are about to book a Gravite manual variant and want to lock in the introductory Rs 82,999 price before it rises.
Skip It If:
- Your monthly running is under 1,000 km. A break-even period of nearly four years rarely makes financial sense.
- You frequently travel with all seven occupants plus full luggage on long trips, since the cargo area is largely occupied after fitment.
- You live in a region with sparse CNG infrastructure. Range anxiety in CNG mode kills the savings story.
- You bought the AMT variant, which is most likely incompatible with this kit.
Wait and Watch If:
- You are cross-shopping the upcoming Renault Triber CNG, which is expected to use a factory-fit underbody twin-tank layout that preserves the cargo area. If full luggage capacity matters, the Triber CNG may be the more elegant solution when it launches.
The bottom line: this kit is built for high-utilisation 7-seater buyers in CNG-dense markets. Match those two boxes, and the Nissan Gravite CNG Kit is one of the smartest Rs 82,999 investments in the Indian sub-4-metre MPV segment today.

Motors77 Verdict
The Nissan Gravite CNG Kit is one of the smartest retrofit solutions launched in the Indian market this year. By stacking two 25-litre cylinders vertically and engineering them through Motozen with ICAT certification, Nissan has answered the single biggest objection buyers had against CNG in this segment, namely the loss of seating practicality. The Rs 82,999 introductory price, the 3-year kit warranty, the BS6.2 compliance, and the seamless dealer installation experience together make this a genuinely well thought out package.
The trade-offs are real and worth acknowledging. Boot space behind the third row is effectively gone after fitment, the kit appears limited to the manual gearbox, and Nissan has not yet shared an official mileage figure for CNG mode. Still, for a 7-seater family that wants lower running costs without dropping a row, this is the most practical answer the sub-4-metre MPV segment has produced so far.
Motors77 Rating: 4.2 / 5
The Nissan Gravite CNG Kit earns its price tag for its engineering ingenuity, its certification depth, and its real-world relevance to Indian families. If you are a high-usage Gravite buyer in a CNG-dense city, this kit is well worth budgeting into your purchase plan.
