Nissan Gravite CNG vs Maruti Suzuki Ertiga S-CNG: Which 7-Seater Is Better?

As fuel prices continue to pinch household budgets, more Indian buyers are turning toward CNG vehicles for lower running costs without jumping to electric mobility. For families needing extra seats and affordable daily commuting, 7-seater CNG cars have become an increasingly sensible option.

For buyers considering a practical 7-seater CNG car, the Nissan Gravite CNG vs Maruti Suzuki Ertiga S-CNG are hard to ignore. While both promise economical family transportation, they cater to very different buyers.

The Gravite CNG enters the market as a more affordable option with a dealer-installed retrofit setup, targeting buyers who want lower ownership costs. Meanwhile, the Ertiga S-CNG continues to build on its strong reputation as one of India’s most trusted family MPVs with a factory-fitted CNG package.

At first glance, both may look like practical 7-seater people movers, but once you dig deeper, the differences become quite clear.

Let’s compare them in detail to understand which one fits your needs better.

Nissan Gravite CNG vs Maruti Suzuki Ertiga S-CNG: Price and Variants

For most Indian buyers, pricing is where the decision begins.

The Nissan Gravite lineup starts at ₹5.65 lakh and goes up to ₹8.93 lakh (ex-showroom). Nissan offers a dealer-installed twin-cylinder CNG retrofit kit priced at an introductory ₹82,999, available through authorised dealerships in select cities.

Even after adding the retrofit cost, the Gravite remains considerably more affordable than the Ertiga.

On the other hand, the Maruti Suzuki Ertiga S-CNG sits in a more premium bracket. The VXi S-CNG variant is priced at ₹10.76 lakh, while the better-equipped ZXi S-CNG costs ₹11.82 lakh (ex-showroom).

Price Comparison Table

Model	Price (Ex-Showroom)
Nissan Gravite CNG	₹5.65 lakh to ₹8.93 lakh + ₹82,999 CNG kit
Maruti Suzuki Ertiga VXi S-CNG	₹10.76 lakh
Maruti Suzuki Ertiga ZXi S-CNG	₹11.82 lakh

Verdict on Pricing

If affordability is your biggest concern, the Gravite clearly has an advantage. It opens the door to 7-seat CNG mobility at a much lower entry cost. However, the Ertiga’s higher price reflects its larger dimensions, stronger engine and factory-integrated setup.

Engine, Performance and Mileage

The biggest difference between these two family cars lies under the hood.

The Nissan Gravite CNG gets a 1.0-litre petrol engine producing 71 bhp and 96 Nm torque. Buyers can choose between a 5-speed manual gearbox and Nissan’s EZ Shift AMT, which can make city driving easier.

Nissan claims the CNG-equipped Gravite delivers up to 24 km/kg, making it a fairly economical option for daily commuting.

Meanwhile, the Maruti Suzuki Ertiga S-CNG comes powered by a larger 1.5-litre petrol engine, paired with a 5-speed manual transmission. In CNG mode, the engine produces 86.6 bhp and 121.5 Nm torque.

More importantly, Maruti claims a higher mileage figure of 26.11 km/kg.

Performance Comparison Table

Specification	Nissan Gravite CNG	Maruti Suzuki Ertiga S-CNG
Engine	1.0L Petrol	1.5L Petrol
Power	71 bhp	86.6 bhp
Torque	96 Nm	121.5 Nm
Gearbox	5MT / AMT	5MT
Mileage	Up to 24 km/kg	26.11 km/kg

Real-World Driving Experience

In daily city use, the Gravite’s smaller engine should feel adequate for short commutes and urban driving. The optional AMT also adds convenience in traffic, something many buyers may appreciate.

However, if you frequently drive with six or seven passengers or travel on highways, the Ertiga’s extra torque and larger engine make a noticeable difference. It feels more relaxed at cruising speeds and better suited for fully loaded family trips.

Honestly, for buyers who regularly travel long distances with family, the Ertiga is likely to feel like the more effortless car to drive.

Space and Practicality: Which One Works Better for Families?

When buying a 7-seater, cabin space matters just as much as mileage.

The Maruti Suzuki Ertiga is the larger vehicle here, measuring 4,395 mm in length with a 2,740 mm wheelbase. This gives it a more spacious cabin, especially in the third row.

For medium and long journeys, the Ertiga feels better suited to carrying adults in all three rows.

The Nissan Gravite, by comparison, measures 3,987 mm long and rides on a 2,636 mm wheelbase.

Its compact size makes city driving and parking easier, but the trade-off comes in rear-seat space. The third row may feel more suitable for children or occasional use.

CNG Tank and Boot Practicality

Nissan uses a twin-cylinder 25-litre setup, which helps preserve luggage practicality to some extent.

Maruti, meanwhile, uses a 60-litre water-equivalent tank, helping deliver better travel range between fuel stops.

For larger families planning weekend trips or highway journeys, the Ertiga again feels like the more practical choice.
