Nissan Gravite Gets Twin Tank CNG Kit For Rs 82,999: Smart Move For A Smart Price
The Nissan Gravite launched in February 2026 with a promise: a factory-approved CNG kit will follow. That kit is now here, and the details are more considered than most retrofit setups that arrive as afterthoughts. Nissan has introduced a twin-cylinder CNG retro-fitment kit for the Gravite, priced at Rs 82,999, available through authorised dealerships across 16 states.
The kit has been developed by Motozen and carries ICAT approval, meaning it meets government safety and emission standards. It is also BS6 Phase 2 compliant. There is a third-party warranty of three years or 1,00,000 km on key components, which is competitive for a retrofit product.
Most CNG retrofits on seven-seater cars create a problem: the tanks eat into either boot space or the third row. Nissan has gone around this with a twin-cylinder setup using two 25-litre tanks instead of a single large cylinder.
The combined 50-litre CNG capacity is comparable to what a single-tank retrofit would offer, but the packaging is different. The tanks are positioned to leave the third row usable, which is the Gravite's primary selling point in the first place.
The Gravite's third-row seats are removable and fold flat, giving you a 625-litre boot in five-seat mode or a 320-litre boot in six-seat mode with the third row up. The CNG kit's twin-tank layout is designed not to compromise either of those configurations in any meaningful way. That is the right engineering priority for a car where versatility and space are the core value proposition.
The Gravite is powered by a 1.0-litre three-cylinder naturally aspirated engine producing 72 PS and 96 Nm. On petrol, the ARAI figure is 19.3 km per litre for the manual and 19.6 km per litre for the AMT.
The CNG kit is only compatible with the manual gearbox variant, not the AMT. That is a hardware limitation of the sequential CNG system, which works with the manual's fuelling and ignition calibration.
CNG pricing varies by city but typically runs between Rs 80 and Rs 95 per kg in most major markets. A CNG vehicle with a 50-litre equivalent tank and a conservative 22-25 km per kg efficiency delivers a per-kilometre running cost that is roughly 40-50 percent lower than petrol.
Over a year of driving 15,000 km, the fuel savings on CNG versus petrol at current prices can comfortably cross Rs 30,000-35,000. The Rs 82,999 kit investment therefore pays back in under three years in a moderate usage scenario, and faster for high-mileage users.
The Gravite is priced from Rs 5.65 lakh to Rs 8.94 lakh ex-showroom as a petrol. Add Rs 82,999 for the CNG kit and installation, and the entry-level CNG-capable Gravite works out at around Rs 7.5 lakh on-road in most cities, still well below the Rs 9.40 lakh that a factory CNG Tekna variant is expected to carry when it eventually arrives.
For someone buying a Gravite primarily as a family MPV and running it on daily school runs, weekend trips, or even limited commercial use, the economics of CNG are straightforward.
The Gravite's competition, primarily the Renault Triber on which it shares its platform, has had a factory CNG option for a while. Nissan has addressed that gap with this retrofit, and unlike a generic aftermarket kit, this comes with OEM backing, an authorised fitment channel, and a meaningful warranty.
The fuel-filling nozzle is neatly integrated under the petrol filler lid, so the exterior looks unchanged. Switching between petrol and CNG is done through a button on the dashboard. The system defaults to CNG on start and switches to petrol automatically when CNG runs low.
