Maruti Suzuki Ertiga

The Maruti Suzuki Ertiga is offered in both petrol and factory-fitted CNG forms, with the CNG version sold as the Ertiga VXi CNG and ZXi CNG. Visually, there is no differentiation between the petrol and CNG models. Both get the updated grille, refreshed alloy wheels and subtle chrome detailing that give the MPV a smarter appearance.

The factory-integrated CNG setup uses a 60-litre tank mounted under the floor, ensuring the Ertiga retains its three-row layout and most of its everyday practicality.

Inside, the 2022 Ertiga gets a handful of updates that make a noticeable difference for everyday use. Keyless entry and a push-button start elevate convenience, while refreshed faux wood trim and new seat upholstery create a more pleasant cabin ambience. The switch from an older 2-DIN unit to a touchscreen infotainment system with Apple CarPlay and Android Auto brings the technology up to modern expectations.

A colour TFT display in the instrument cluster provides clear readouts of CNG level and the CNG-to-fuel ratio. Roominess has always been an Ertiga strength and the middle row remains spacious with good recline and seat adjustment, making long journeys comfortable. The third row is useable even for passengers over six feet tall once the middle row is suitably configured. Boot space is reduced by the CNG tank but still accommodates soft luggage reasonably well.

The Ertiga petrol is powered by the 1.5-litre K15C DualJet petrol engine, producing around 100hp and 136Nm, paired exclusively with a 5-speed manual gearbox in this review context.

The Ertiga CNG uses the same engine, but when running on CNG, output drops to around 87hp and 121.5Nm. The car always starts in petrol mode and automatically switches to CNG once operating temperatures are reached.

On the move, the performance gap between petrol and CNG is smaller than expected. The Ertiga CNG pulls cleanly from low speeds and feels tractable in urban driving, aided by well-spaced gear ratios. While outright acceleration is slower, drivability remains largely intact, especially with light to moderate loads.

In instrumented testing, the Ertiga CNG takes about 15.5 seconds to reach 100kph, compared to 13.9 seconds for the petrol Ertiga, but in everyday driving the difference is far less noticeable.

Efficiency is where the Ertiga CNG clearly justifies its existence. Maruti Suzuki claims 26.11km per kg of CNG, and real-world testing returned 22.32km per kg, which is excellent for a seven-seat MPV.

The petrol Ertiga, while more flexible and quicker, cannot match the CNG version’s low running costs, making the VXi CNG and ZXi CNG the preferred choices for high-mileage users.

Ride quality is well suited to the Ertiga’s role. With a full load on board, body motions remain composed, and the added weight of the CNG system slightly dampens pitch and bounce over rough surfaces. At low speeds ride quality can feel a bit firm, especially when unloaded, but on highways the MPV feels stable and planted, giving confidence even at triple-digit speeds. Steering is light and easy for city driving and parking, though it does not provide highly communicative feedback.

Handling is predictable rather than engaging, which fits the Ertiga’s character as a people mover. The focus is clearly on comfort and ease of use rather than sharp dynamics.

The updated Ertiga is well equipped for its class. In addition to the touchscreen infotainment and TFT instrument cluster, it offers features such as keyless entry and push-button start. Safety kit includes four airbags, ABS with EBD and a fire extinguisher mounted under the middle row seat for ready access.

While it misses out on higher-end comforts such as cruise control and ventilated seats, its core practical feature set matches its utilitarian focus and adds value for families and regular travellers.

At a price between approximately ₹10.41 lakh and ₹11.54 lakh (ex-showroom), the Ertiga CNG stands in a segment of its own. No other seven-seat MPV offers a factory-fitted CNG option, which has kept waiting lists long and demand strong. The availability of a higher ZXi trim broadens its appeal with more equipment and convenience.

Its core strengths of space, practicality, smooth integration of the CNG system and low running costs make it a compelling choice for families and high-mileage users who want the utility of a seven-seater without high fuel expenditure.
