Kia India is aggressively expanding its three-row MPV portfolio with the introduction of factory-fitted CNG versions of the Carens and the newer Carens Clavis.
The new CNG variants are aimed squarely at buyers demanding the flexibility and practicality of a three-row family vehicle, while keeping everyday running costs significantly lower than a conventional petrol MPV. The standard Kia Carens CNG enters the market at an introductory price of ₹12.11 lakh, while the Carens Clavis CNG starts slightly higher at ₹12.39 lakh (ex-showroom).
It is crucial to note that unlike the earlier dealer-fitted Lovato CNG kits available for the Carens, these new versions roll out with a comprehensive, factory-integrated CNG system. This integration goes far beyond bolting a tank into the boot; it includes specific engine recalibration, beefed-up suspension, and upgraded braking hardware to handle the additional mass.
Kia Carens CNG & Clavis CNG Price
Kia is keeping the variant lineup relatively streamlined for its factory CNG debut. The standard Carens is offered in a single trim, while the Clavis provides two options.
| Model | Variant | Fuel | Transmission | Ex-showroom Price |
| Carens | Premium (O) | CNG | 6MT | ₹12.11 lakh |
| Carens Clavis | HTE | CNG | 6MT | ₹12.39 lakh |
| Carens Clavis | HTE (O) | CNG | 6MT | ₹13.35 lakh |
(All prices are ex-showroom, India)
How Much More Does the CNG Cost?
For buyers weighing their options, understanding the exact price premium over the standard petrol model is the first step in deciding if CNG makes financial sense.
| Variant | Petrol MT | CNG MT | Difference |
| Carens Premium (O) | ₹11.12 lakh | ₹12.11 lakh | ~₹1 lakh |
| Clavis HTE | ₹11.39 lakh | ₹12.39 lakh | ₹1 lakh |
| Clavis HTE (O) | ₹12.35 lakh | ₹13.35 lakh | ₹1 lakh |
Across the board, the factory-fitted CNG system commands a flat ₹1 lakh premium over the equivalent naturally aspirated petrol-manual variants. This precise price gap sets up a clear mathematical equation for buyers: how many kilometers do you need to drive to recover that ₹1 lakh through lower fuel costs?

Kia Carens CNG Engine Specifications
Both the Carens and Carens Clavis utilize Kia’s familiar 1.5-litre naturally aspirated Smartstream petrol engine, heavily adapted to run on compressed natural gas.
CNG Output:
- Power: 96 PS
- Torque: 123 Nm
- Transmission: 6-speed manual
- Drive: Front-wheel drive
The CNG versions produce less power and torque than their petrol counterparts (which generate roughly 115 PS and 144 Nm). Kia has recalibrated the engine control unit (ECU) specifically for CNG operation to ensure power delivery remains as linear and usable as possible despite the output drop. Currently, there is no automatic transmission available with the factory-fitted CNG variants.
60-Litre CNG Cylinder and Dual-Fuel Setup
Both MPVs feature a 60-litre (water-equivalent) CNG cylinder seamlessly integrated alongside the existing petrol fuel tank. This dual-fuel capability allows drivers to switch effortlessly between petrol and CNG on the fly, eliminating range anxiety during long trips where CNG stations might be sparse.
An important practical detail: Kia has successfully managed to package the CNG hardware without sacrificing the spare wheel, which remains securely mounted underneath the vehicle.
Kia Carens CNG Boot Space
There is no escaping the laws of physics—adding a large gas cylinder compromises luggage capacity.
The CNG cylinder is bolted into the boot area behind the third row. With all three rows of seating in use, boot space falls to 116 litres (down from the standard 216 litres).
This is a significant compromise. Buyers must carefully evaluate how much luggage they typically haul when all seven seats are occupied. If you frequently do airport runs with a full house, the reduced boot space will require a roof carrier.
Kia Carens CNG Mileage
Kia has not yet released the official ARAI-certified fuel efficiency figures for the new CNG versions. However, based on the powertrain and vehicle weight, industry expectations place the mileage roughly in the region of 22–25 km/kg.
Please note: This is an expected figure, not an official claim. We will update this section the moment Kia publishes the certified testing numbers.
What Changes on the CNG Versions?
A factory-fitted system is vastly superior to an aftermarket job because the manufacturer engineers the entire vehicle around the added weight and fuel type. Kia has implemented several key mechanical upgrades:
- CNG-specific engine calibration: Prevents engine knocking and optimizes valve timing for the drier, hotter combustion of natural gas.
- Modified suspension: The rear springs and dampers have been retuned to prevent the MPV from sagging under the weight of a full 60-litre steel cylinder.
- Upgraded front disc brakes: Larger 16-inch front discs provide the extra stopping power required to rein in the heavier vehicle.
- 16-inch wheels: Standard across all CNG models to improve load-bearing capability.
- Revised third-row seat-back: The seat frame has been modified so passengers can still recline comfortably without hitting the cylinder enclosure.
CNG Distance-to-Empty Display
Integration extends to the cabin electronics. Drivers get a dedicated 4.2-inch colour TFT Multi-Information Display (MID) that features CNG-specific Distance-to-Empty (DTE) logic. Alongside a factory-finish fuel-change switch on the dashboard, the system feels completely native to the car.
Factory-Fitted CNG vs Dealer-Fitted CNG
This launch draws a hard line under Kia’s previous CNG strategy. The Carens was previously available with a dealer-installed Lovato CNG kit. The new versions are entirely different beasts.
Why factory-fitted matters:
- Manufacturer-integrated hardware designed during the R&D phase.
- Upgraded suspension and braking components to handle the weight safely.
- Flawless integration with the vehicle’s ECU and dashboard displays.
- Uncompromised factory warranty support without third-party finger-pointing.
For a family buyer, the peace of mind offered by a factory-engineered system heavily outweighs the slight cost savings of an aftermarket conversion.
Kia Carens CNG vs Carens Clavis CNG
If you are set on a Kia CNG MPV, which one do you choose?
Carens CNG (Premium O)
- Price: ₹12.11 lakh
- Best for: Buyers who want the absolute lowest-cost entry into a three-row Kia CNG vehicle.
Carens Clavis CNG (HTE / HTE O)
- Price: ₹12.39 lakh to ₹13.35 lakh
- Best for: Buyers who prefer the newer, more rugged Clavis design language and are willing to spend slightly more for it. The starting price gap is a mere ₹28,000, making the newer Clavis an incredibly tempting upgrade.
Kia Carens Clavis CNG vs Diesel
This is where the pricing strategy gets fascinating. The Clavis HTE (O) diesel starts at ₹14.37 lakh, while the identically equipped CNG version costs ₹13.35 lakh. That positions the CNG model approximately ₹1.02 lakh below the diesel.
Choose CNG for: A lower initial purchase price, the potential for lower per-kilometer fuel costs in the city, and the flexibility of running on petrol.
Choose Diesel for: Superior high-speed highway cruising, massive torque (250 Nm vs 123 Nm) for carrying heavy loads, and the availability of an automatic gearbox.
Who Should Buy the Kia Carens CNG?
The CNG variants are tailor-made for buyers who:
- Clock significant kilometers every month, primarily within city limits.
- Have convenient, low-wait-time access to CNG stations on their daily route.
- Require a practical three-row vehicle for school runs and family duties.
- Demand the safety and reliability of a factory-fitted system.
- Are perfectly comfortable shifting a manual transmission in traffic.
Who Should Avoid the CNG Version?
Skip the CNG and look at the petrol or diesel models if:
- You frequently blast down highways for long-distance road trips.
- CNG infrastructure in your city is sparse or involves hour-long queues.
- You absolutely require the convenience of an automatic transmission.
- You regularly carry seven adults along with their luggage.
- You want strong, effortless overtaking performance. The 96 PS output is tuned strictly for economy, not speed.
Is the Kia Carens CNG Worth Buying?
The introduction of factory-fitted CNG transforms the Carens family into one of the most versatile MPV lineups in the country. Kia now gives buyers the power of choice: naturally aspirated petrol, punchy turbo-petrol, torque-heavy diesel, pure electric (via the upcoming Clavis EV), and now, ultra-economical CNG.
The ₹1 lakh premium over the standard petrol model is a significant upfront chunk of change. However, for a high-mileage driver, the dramatically lower cost of compressed natural gas will absolutely recover that investment over time.
The compromises are stark—reduced boot space (116 litres), a manual-only gearbox, and blunted acceleration. But if your primary goal is transporting your family across the city with the absolute lowest possible fuel bills, the factory-fitted Kia Carens CNG and Carens Clavis CNG are arguably the most compelling three-row options on the market today.
