Kia India is gearing up to expand its eco-friendly vehicle lineup with the launch of the much-anticipated Sonet CNG variant. As the demand for fuel-efficient SUVs continues to rise, especially among budget-conscious and environmentally aware Indian consumers, the introduction of the Sonet CNG could be a game-changer in the compact SUV segment. Here’s everything you need to know about the upcoming CNG version of the Sonet, including its mileage, pricing expectations, and launch timeline.
Why a CNG Variant for the Sonet?
The compact SUV segment in India is fiercely competitive. However, with rising fuel prices and stricter emissions norms, more buyers are shifting toward fuel-efficient SUVs that also reduce the environmental footprint. Recognizing this shift, Kia India has smartly decided to bring a CNG-powered version of the Sonet, offering a viable alternative to traditional petrol and diesel options.
Moreover, the success of other CNG SUVs in the Indian market has already set a strong precedent. Models like the Tata Nexon and Maruti Brezza have proven that there is a demand for utility vehicles that are also economical to run.
Expected Mileage of Kia Sonet CNG
One of the key selling points of any CNG vehicle is its mileage, and the Sonet CNG is expected to deliver impressive fuel efficiency. Based on early test vehicle sightings and engine specs from the standard Sonet, industry experts estimate the Kia Sonet CNG mileage to be around 25-27 km/kg.
This would place it among the top performers in the compact SUV category, offering substantial savings on running costs compared to its petrol and diesel counterparts.
Engine and Performance Details
The Sonet CNG will likely be powered by Kia’s 1.2L naturally aspirated petrol engine, which has already been adapted for CNG use in test mules. This engine is known for its refinement and reliability. While the CNG variant may have slightly lower power output compared to the petrol-only version (due to combustion characteristics of CNG), it will still be adequate for daily city commutes and occasional highway runs.
The Sonet CNG is expected to come with a 5-speed manual transmission initially. An automatic CNG variant might follow based on demand and consumer feedback post-launch.
Interior and Features
Kia has built a reputation in India for offering feature-rich vehicles, and the CNG version of the Sonet is unlikely to be an exception. While Kia may offer the CNG kit only in select mid-level trims (like HTK or HTK+), the SUV is expected to retain premium touches such as:
-
An 8-inch touchscreen infotainment system
-
Android Auto and Apple CarPlay
-
Rear parking camera
-
Steering-mounted controls
-
Dual airbags and ABS
Kia India might tweak the boot space slightly to accommodate the CNG tank, but the overall design and interior layout will remain consistent with the petrol versions.
Expected Price of Kia Sonet CNG in India
Kia is known for pricing its products competitively. The Sonet CNG price in India is expected to carry a premium of about ₹90,000 to ₹1.10 lakh over its corresponding petrol variant. This means the starting ex-showroom price for the CNG trim could be in the range of ₹9 lakh to ₹10.5 lakh, depending on the final variant mix.
This pricing positions the Sonet CNG as an affordable yet feature-rich option for buyers who want a compact SUV with lower running costs.
Launch Date and Availability
The official launch of the Kia Sonet CNG in India is expected in the second half of 2025, with most signs pointing to a festive season release (around October–November). Kia India may begin taking bookings a few weeks in advance to build anticipation and assess initial demand.
The Sonet CNG will initially be available in metro cities and tier-1 markets where CNG infrastructure is more established. Gradually, the availability will expand based on market response and dealer readiness.
Market Impact and Competitors
With the introduction of the Sonet CNG, Kia India will further strengthen its portfolio in the fuel-efficient SUV space. This variant will compete directly with the Maruti Brezza CNG and the upcoming Hyundai Venue CNG.
What sets the Sonet apart is its premium appeal, tech-forward features, and Kia’s growing service network. The CNG variant can potentially attract young urban buyers and fleet operators alike, offering them a stylish yet cost-effective mobility solution.
