Kia Sonet Price After GST Cut: Old vs New Prices Explained

The Kia Sonet has been one of the most successful compact SUVs in India since its launch. Known for its stylish design, feature-rich interiors, and a wide range of engine options, the Sonet has carved out a loyal customer base. Whether you want the efficiency of a 1.2-litre petrol engine, the punch of a 1.0-litre turbo-petrol, or the long-distance economy of a 1.5-litre diesel, the Sonet has something for every kind of buyer.

Now, the popular SUV has become even more attractive after the government’s new GST 2.0 tax reform, which came into effect on 22 September 2025. The new regime simplifies taxation on cars and SUVs under 4 metres, leading to a sharp drop in prices across different variants of the Kia Sonet.

This article provides a complete breakdown of the Kia Sonet Price After GST Cut, comparing old and new ex-showroom prices for both petrol and diesel variants, while also explaining why this reduction happened and how it benefits customers.

What Changed with GST 2.0?

Before GST 2.0, compact cars and SUVs were taxed differently based on fuel type and engine size.

• Petrol cars under 1.2L attracted 28% GST + 1% cess (29% effective).
• Diesel cars under 1.5L attracted 28% GST + 3% cess (31% effective).

With GST 2.0, the government has introduced a flat 18% GST for all compact vehicles under 4 metres. This has brought a uniform tax structure and has resulted in significant price cuts for customers.

For Kia Sonet, this means:

• Petrol variants now cost around 8.53% less than before.
• Diesel variants get an even bigger drop of 9.92%, as they previously had a higher tax burden.

Kia Sonet Petrol Variants – Old vs New Price

The petrol lineup of the Sonet includes the 1.2-litre naturally aspirated and 1.0-litre turbo-petrol engines. These trims now fall under the 18% tax bracket, resulting in substantial price reductions.

Why Did Kia Sonet Prices Drop After GST Cut?

The primary reason is the removal of cess and the introduction of a uniform GST slab. Earlier, petrol and diesel cars had different effective tax rates, which made diesel cars more expensive. Now:

• Small petrol cars: Tax dropped from 29% → 18%
• Small diesel cars: Tax dropped from 31% → 18%

This translates to a 11–13% lower tax burden, directly reducing ex-showroom prices.

From When Are These Prices Applicable?

The reduced prices under GST 2.0 are effective from 22 September 2025. Any Kia Sonet purchased or invoiced after this date will reflect the new prices.

How Much Can Buyers Save?

Depending on the variant, buyers can now save anywhere between ₹68,000 to ₹1.56 lakh on the Kia Sonet. Diesel buyers benefit the most, but even petrol trims see a healthy reduction of more than ₹1 lakh in higher models.

What This Means for the Compact SUV Market

The Kia Sonet has always been one of the most competitive SUVs in its segment, going up against rivals like Hyundai Venue, Maruti Brezza, Tata Nexon, and Mahindra XUV300. With the new GST cut, the Sonet becomes even more value-for-money, especially for buyers who were previously hesitant about diesel prices.

This price revision could also put pressure on other manufacturers to pass on similar benefits to customers, leading to a fresh wave of competition in the sub-4 metre SUV space.
