Best Mileage CNG MPVs in India (2026)

The Maruti Suzuki Eeco has the best CNG mileage of any MPV in India, at 26.78 km/kg. It is followed closely by the Maruti Suzuki XL6 at 26.23 km/kg, then the Maruti Suzuki Ertiga and Toyota Rumion tied in third at 26.11 km/kg each. All four sit within 0.7 km/kg of each other, which in practice means essentially the same real-world efficiency, since they share closely related, naturally aspirated CNG hardware. The Kia Carens Clavis sits apart from those four, though not for the reason usually given: Kia publishes no ARAI-certified CNG figure for it at all, so it cannot be ranked here on a like-for-like basis.

If running costs are the main reason you're considering an MPV on CNG, it helps to know upfront that the choice is narrower than it looks. Only a handful of MPVs in India offer a factory-fitted CNG option at all, and four of the five here share closely related Maruti hardware, which is why their mileage figures land so close together. The fifth, from Kia, is the one Maruti has no hand in. Here's exactly how they compare.

Maruti Suzuki prices and mileage figures come from its own brochures and price pages. Toyota does not publish ex-showroom prices online, and the Kia numbers could not be checked against a manufacturer price page either, so those figures are our own and are worth confirming with a dealer.

Frequently asked questions

Which MPV has the best CNG mileage in India?

The Maruti Suzuki Eeco, at 26.78 km/kg, though it's a genuinely basic vehicle compared to the others on this list.

Which full-featured MPV has the best CNG mileage?

The Maruti Suzuki XL6, at 26.23 km/kg, offering the best mileage among MPVs that aren't stripped-down commercial-style vehicles.

Why is the Kia Carens Clavis so far behind on CNG mileage?

Kia has not published an ARAI-certified CNG figure for the Clavis, so any mileage number you see for it is an estimate rather than a certified one. Its SmartStream G1.5 is naturally aspirated like the Maruti units, but it runs a higher CNG-mode output at 96 PS against their 87.8 PS, which works against efficiency.

Do any MPVs offer an automatic transmission with CNG?

No. Every MPV with a CNG option in India, the Eeco, XL6, Ertiga, Rumion, and Carens Clavis, is manual only on CNG.

Which MPVs don't offer CNG at all?

The Toyota Innova Crysta, Toyota Innova Hycross, Maruti Suzuki Invicto, Renault Triber, and Nissan Gravite currently have no factory-fitted CNG option in India.
