A seven-seat MUV with the third row in use

7-Seater MUVs With the Lowest Running Cost Per Km in India (2026)

Across the 7-seat MUV field, factory CNG wins on running cost by a margin no hybrid or diesel closes. The Maruti Suzuki Ertiga CNG costs about ₹3.26 per km on 26.11 km/kg, roughly a third less than everything else here. The Maruti Invicto and Toyota Innova Hycross share a 2.0-litre strong hybrid rated at 22.16 km/l and land together at about ₹4.51, though Maruti quotes 139 kW (188.9 PS) for the Invicto where Toyota quotes 186 PS for the Hycross. The Kia Carens Clavis 7-seat diesel follows at ₹4.61, the Ertiga petrol at ₹4.88 on 20.51 km/l, and the Renault Triber at ₹5.26. The Ertiga was the first factory CNG MPV here, but the XL6, Toyota Rumion and Carens Clavis now offer it too.

The Maruti Suzuki Ertiga CNG is the cheapest 7-seater MUV to run in India, at roughly ₹3.26 per km on its ARAI-certified 26.11 km/kg. The Maruti Suzuki Invicto and Toyota Innova Hycross strong hybrids come next at about ₹4.51 per km (22.16 kmpl), followed by the Kia Carens Clavis 7-seat diesel at ₹4.61, the Ertiga petrol at ₹4.88 and the Renault Triber at ₹5.26. A 7-seater MUV covers a lot of ground in India, from budget family runabouts to premium hybrid people-movers costing three times as much. That spread means running cost varies just as widely, and a buyer comparing two 7-seaters on sticker price alone can easily miss a real difference in what each one actually costs to keep fueled over years of ownership.

Fuel type matters more than body size or purchase price in this segment. A compact, affordable 7-seater running on plain petrol can cost noticeably more per kilometer than a pricier rival built around CNG or a hybrid powertrain, because the fuel economics do most of the work here, not the size of the cabin. Running cost is worth checking on its own terms rather than assuming it tracks neatly with what you paid at the dealership.

This list ranks 7-seater MUVs in India by estimated running cost per kilometer, based on ARAI-certified mileage across CNG, hybrid, diesel, and petrol powertrains. Buyers who don't need a full 7 seats can also check our breakdown of 6-seater MPVs with the lowest running cost, which covers the models that seat six rather than seven.

Maruti Suzuki and Toyota figures here are the ARAI-certified numbers printed in each model's own brochure. Kia and Renault either block automated access or do not print ARAI mileage, so those figures are our own and are worth confirming with a dealer.

Key takeaways

  • Lowest running cost overall: The Maruti Suzuki Ertiga CNG comes out cheapest at roughly ₹3.26 per km, helped by the same factory CNG technology found across Maruti's lineup.
  • Hybrid beats diesel in this segment, but not CNG: The Invicto's strong hybrid powertrain undercuts every diesel 7-seater here, though it still trails CNG on pure running cost.
  • Price and running cost don't move together: The most affordable 7-seater on this list doesn't have the lowest running cost, and the priciest hybrid doesn't have the highest.

Ranking methodology

Running cost per km is calculated as fuel price divided by ARAI-certified mileage. Only genuine 7-seat configurations are used here. 6-seat and 8-seat variants of the same model are left out to keep the comparison consistent, since seating count can change the mileage figure a manufacturer reports for that specific trim.

Where a model offers more than one transmission, whichever one actually returns the better mileage on that vehicle is used for the ranking, since that isn't always the manual. Fuel prices are held constant across every entry, so the differences here come down to mileage and powertrain technology rather than shifting local fuel costs.

Each MUV in detail

1. Maruti Suzuki Ertiga CNG

Price: Around ₹10.76 lakh to ₹12.44 lakh ex-showroom, across VXi and ZXi CNG trims.

The Ertiga CNG was the first factory-fitted CNG MPV in India and is still the cheapest 7-seater to run on this list by a wide margin. The XL6, Toyota Rumion and Kia Carens Clavis now offer factory CNG too. The Rumion is a rebadged Ertiga on the same 26.11 km/kg, and the 6-seat XL6 is fractionally ahead at 26.23 km/kg, so the Ertiga's lead here is over the non-CNG cars rather than over its own stablemates.

Engine: 1462cc K15C petrol, producing 100.6 PS and 137.1 Nm in petrol mode and 87.8 PS and 121.5 Nm in CNG mode.

Mileage: 26.11 km/kg, confirmed against Maruti's official mileage page.

Estimated running cost: ₹3.26 per km.

Seating: 7 seats.

Transmission: 5-speed manual only on CNG.

Warranty: 3 years or 1,00,000 km, standard.

2. Maruti Suzuki Invicto (7-seat strong hybrid)

Price: ₹24.97 lakh ex-showroom for the Zeta Plus 7S, with the range topping out at ₹28.80 lakh.

The Invicto's 7-seat Strong Hybrid trim posts the best running cost of any non-CNG 7-seater in India, helped by a hybrid system shared with its Toyota counterpart.

Engine: 2.0-litre petrol producing 139 kW (188.9 PS) and 206 Nm combined with the hybrid motor.

Mileage: 22.16 kmpl, consistent across every Invicto trim and seating configuration.

Estimated running cost: ₹4.51 per km.

Seating: 7 seats on this trim; 8-seat variants are also available.

Transmission: e-CVT automatic only.

Warranty: 3 years or 1,00,000 km, standard.

3. Toyota Innova Hycross (7-seat strong hybrid)

Price: From roughly ₹25.90 lakh ex-showroom for the hybrid range.

The Innova Hycross shares its hybrid powertrain with the Invicto. Its 7-seat configuration adds captain seats in the second row, a genuine comfort upgrade over the bench-seat 8-seat version.

Engine: 2.0-litre petrol producing 186 PS combined with the hybrid motor, which is Toyota's rating for the same system Maruti quotes at 188.9 PS.

Mileage: 22.16 kmpl.

Estimated running cost: ₹4.51 per km.

Seating: 7 seats with captain seats; an 8-seat bench version is also offered.

Transmission: e-CVT automatic only.

Warranty: Standard Toyota warranty terms apply.

4. Kia Carens Clavis (7-seat diesel)

Price: From ₹13.50 lakh ex-showroom (HTE Diesel MT).

The Carens Clavis's 7-seat diesel manual posts a noticeably better mileage figure than the automatic-only 6-seat diesel variant of the same car, making it the stronger pick for buyers who don't specifically need captain seats.

Engine: 1.5-litre diesel, producing 116 PS and 250 Nm.

Mileage: 19.54 kmpl, on the manual transmission.

Estimated running cost: ₹4.61 per km.

Seating: 7 seats.

Transmission: 6-speed manual; an automatic is available on higher trims at a lower 17.5 kmpl.

Warranty: 3 years, unlimited km.

5. Maruti Suzuki Ertiga petrol

Price: ₹8.90 lakh to ₹13.04 lakh ex-showroom.

The Ertiga petrol is one of the most affordable 7-seaters in India to buy, though its running cost trails its own CNG sibling by a wide margin.

Engine: 1462cc K15C petrol, producing 75.8 kW (103.06 PS) and 139 Nm.

Mileage: 20.51 kmpl (manual) or 20.30 kmpl (automatic), confirmed against Maruti's official mileage page.

Estimated running cost: ₹4.88 per km on the manual.

Seating: 7 seats.

Transmission: 5-speed manual or 6-speed torque converter automatic.

Warranty: 3 years or 1,00,000 km, standard.

6. Renault Triber

Price: Among the most affordable 7-seaters on sale in India.

The Triber closes out this list with the highest running cost, which is the trade-off for being one of the lightest and most affordable 7-seat MUVs on the market.

Engine: 1.0-litre, 3-cylinder petrol engine.

Mileage: 19 kmpl.

Estimated running cost: ₹5.26 per km.

Seating: 7 seats.

Transmission: 5-speed manual or 5-speed AMT.

Warranty: Standard Renault warranty terms apply.

Conclusion

For the lowest running cost in a 7-seater MUV, CNG is still unbeaten, and the Ertiga's factory-fitted system keeps it well ahead of every hybrid, diesel, and petrol alternative on this list. Buyers who want more premium features or a bigger cabin without giving up too much on running cost should look at the Invicto or Innova Hycross, both of which beat every diesel option here despite their higher purchase price. Anyone shopping specifically for diesel should pick the Carens Clavis's manual 7-seat trim over its automatic 6-seat sibling, since the mileage difference between the two is large enough to matter over a typical ownership period. For buyers who don't need all 7 seats, it's also worth checking our 6-seater MPV running cost comparison and the full Maruti Suzuki lineup before settling on a final choice.
