The Nissan Gravite has already made waves as a budget-friendly rival to the Renault Triber and Maruti Ertiga. However, for high-mileage users and large families, petrol costs are always a concern. With the launch of the new Motozen-developed CNG kit, Nissan is offering a solution that slashes running costs without turning your 7-seater into a 5-seater.
1. The Twin-Cylinder Innovation
Traditional CNG tanks are large, heavy “bombs” that sit in the boot, usually forcing you to fold or remove the third-row seats entirely. Nissan has bypassed this by using a smart twin-cylinder layout (2 x 25 litres).
- Vertical Stacking: By stacking two smaller 25-litre tanks vertically, Nissan has managed to retain the full 7-seat functionality of the Gravite.
- The Boot Space Catch: While the seats remain usable, the vertical tanks do consume almost all of the 84-litre boot space available when seven people are on board. However, for those who value “people-moving” over luggage capacity, this is a revolutionary packaging feat in the sub-4-metre segment.
2. Technical Specs and Compatibility
The retrofit kit is specifically tuned for the Gravite’s 1.0-litre naturally aspirated engine, which produces 72 PS and 96 Nm in petrol mode.
| Feature | Specification |
| Kit Type | Sequential BS6.2 & ICAT-Approved |
| Tank Capacity | 50 Litres Total (2 x 25L) |
| Technology | Dynamic Advancer Technology for smooth power |
| Fueling | Dedicated point located under the fuel lid |
| Transmission | Available for Manual Transmission variants only |
While official CNG mileage figures are still being finalized, it is expected to hover around the 25–27 km/kg mark, making it significantly more economical for daily urban commutes than the petrol-only 19.3 kmpl.
3. Dealer-Level Assurance
Unlike third-party kits that might void your warranty, this is a factory-approved solution.
- Installation: Available across 60 cities in 16 states at authorized Nissan dealerships.
- Warranty: The kit comes with a 3-year or 1,00,000 km warranty (provided by the third-party vendor but supported through Nissan), mirroring the standard warranty of the car itself.
- Safety: The system features heavy-duty 8.1 mm thick cylinders and seamless petrol-to-CNG switchover tech.
The Verdict
At an all-in price of roughly ₹6.5 lakh to ₹9.7 lakh (including the kit), the Gravite CNG is now one of the most affordable 7-seater “green” cars in India. It effectively undercuts the Maruti Ertiga CNG by a significant margin while offering better seating flexibility than the current Renault Triber.
