Best CNG MPVs Under 15 Lakh in India (2026): Prices, Certified km/kg and CNG Variants

Four MPVs in India sell a factory-fitted CNG variant under ₹15 lakh: the Maruti Suzuki Ertiga, the Maruti Suzuki XL6, the Toyota Rumion and the Kia Carens Clavis. The Ertiga is the cheapest of them, at ₹10,93,800 for the VXi CNG. The XL6 carries the highest certified figure at 26.23 km/kg. The Kia Carens Clavis is the most powerful at 96 PS in CNG mode, though Kia publishes no certified CNG efficiency figure for it.

Because the kit is fitted by the manufacturer, it stays inside the car's warranty and communicates with the instrument cluster, which a retrofitted kit does not. All four come with a manual gearbox only, and all four carry six airbags.

1. Maruti Suzuki Ertiga

The cluster adds a dedicated CNG fuel gauge and a total CNG mode time readout. The CNG variants keep the same seven-seat layout as the petrol, with a 60:40 split second row and a 50:50 split third row. The split-type luggage board is the one thing the CNG variants go without.
