The Kia Sonet has carved a strong presence in India’s compact SUV market with its stylish design, feature-rich interiors, and multiple engine options. It offers something for everyone – from efficient 1.2-litre petrol trims to the sporty 1.0-litre turbo-petrol and the frugal 1.5-litre diesel.

With the implementation of GST 2.0 from September 22, 2025, the Sonet has witnessed a major price drop. The new tax regime simplifies the structure, lowering levies on compact cars and SUVs under 4 metres. This makes the Sonet even more attractive for buyers across fuel choices.

Here’s a detailed breakdown of how the new GST policy impacts the Sonet’s petrol and diesel variants.

Kia Sonet (Petrol Variants) New Prices after the GST Cut

The petrol lineup of the Sonet includes both the 1.2-litre naturally aspirated engine and the 1.0-litre turbo-petrol engine. Earlier, these variants attracted a tax rate of 28% GST plus 1% cess (29% total). With GST 2.0, the new tax rate stands at 18% flat, resulting in a significant price cut of around 8.53% across the petrol range.

Why have the prices been reduced for the Kia Sonet?

Under the earlier tax structure, smaller petrol and diesel engines under 4 metres were charged at different effective rates. Now, with a uniform 18% GST for small cars and compact SUVs, the Sonet’s entire lineup becomes more affordable. This gives buyers savings across the board, with diesel trims benefiting the most.

Category	Old GST	Old Cess	Old Total Tax	New GST	New Total Tax	Change in Tax
Small petrol cars	28%	1%	29%	18%	18%	11% lower than before
Small diesel cars	28%	3%	31%	18%	18%	13% lower than before

When are the new rates applicable?

The new GST rates will be applicable from September 22, 2025. Any Kia Sonet invoiced or delivered on or after this date will reflect the reduced prices.

If you are looking for a feature-rich compact SUV with sporty performance, the Kia Sonet could be an ideal option. Now, thanks to the GST revision on cars, you can save up to ₹1.56 lakhs, depending on the variant you choose.

Disclaimer: The new prices mentioned in this article are tentative and based on the revised GST rates applicable from 22 September 2025. Final ex-showroom prices may vary slightly as manufacturers and dealerships update their pricing structures in line with the new taxation policy.

Frequently Asked Questions

Here are some of the most frequently asked questions about CNG cars vs petrol cars.

Which car should I buy, petrol or CNG?

That depends on your usage and priorities. A CNG car is a better choice if your daily driving includes long commutes within the city and you want to save on fuel costs. However, a petrol car might be more convenient if you prefer better performance, easier maintenance, and frequent travel to areas without CNG stations.

Is CNG good for the long term?

CNG is good for long-term usage, especially for city driving and regular commutes. It’s cost-effective and eco-friendly, but it requires slightly more maintenance. If you properly care for the CNG kit and engine, it can last as long as a petrol car.

Which fuel is best for a car?

There’s no one-size-fits-all answer. Petrol is best for power, smoother drives, and ease of refuelling. CNG is the most economical for daily use and much cleaner for the environment. If you're focused on savings and low emissions, CNG is best. If performance and convenience are more important, petrol leads.

Which CNG car is best under ₹10 lakh?

Some of the best CNG cars under ₹10 lakh include the Maruti Wagon R CNG, Tata Tiago CNG, Maruti Alto K10 CNG, and Maruti Celerio CNG. These cars offer great mileage, solid features, and are reliable for daily driving.

Which fuel car is best for long drives?

For long drives, petrol cars are still preferred due to better power delivery, wider fuel station availability, and smoother highway performance. CNG cars are more suited for city use and may not offer the same driving range or ease of refuelling on highways.

Which is the No. 1 CNG car?

The Maruti Suzuki Wagon R CNG is widely regarded as the No. 1 CNG car in India. It delivers excellent mileage, has spacious interiors, and enjoys strong brand trust and resale value.

Which is better, CNG or EV?

CNG is more affordable upfront and perfect for people without easy access to EV charging. On the other hand, EVs are more eco-friendly and cheaper to run in the long run. If infrastructure and budget allow, EVs are future-ready. But for now, CNG remains a practical and efficient bridge between petrol cars and full electric mobility.
