Kia is one of the best-selling car brands in India. Like its parent brand, Hyundai, the Korean carmaker is known for offering refined cars at affordable prices. Continuing its strong sales performance in December 2025, Kia sold 18,659 units, as the Kia Sonet maintained the position of the best-selling Kia car. Here is a look at the top-selling Kia cars and how the Kia Sonet outsold every other Kia car.
Why is the Kia Sonet the Best-Selling Kia Car in December 2025?
While Kia has spent nearly six years in the Indian market, it is considered a relatively new brand. Most Indian buyers usually remain tentative before trusting a new car brand and first want to try something inexpensive. Because of this, the Kia Sonet, which is the most affordable Kia car in India, caught the attention of many prospective buyers. However, the context is slightly deeper than that. Despite coming from a relatively new brand, the Kia Sonet has proven to be a trustworthy proposition. It was launched in 2020, and most Sonet owners have reported it to be more than a good car. This makes the Sonet a tried and trusted car from a relatively new car brand. The other factor that favours the Sonet more than other Kia cars is the fact that it is a compact SUV, one of the hottest-selling cars today.

Kia Sonet
The Kia Sonet sold 9,418 units in December 2025, seeing a 182 percent growth over the 3,337 units it sold in the same month last year.

Kia Seltos
With sales of 4,369 units in December 2025, the Kia Seltos saw a 54 percent growth in its year-on-year sales. In the last few years, the Seltos has suffered a serious decline in its popularity. This decline can be directly attributed to the increased competition in the segment, with a slew of cars getting into the segment in the last few years, for example, Tata Curvv, Honda Elevate, Maruti Grand Vitara, and more. Even the arrival of its younger sibling, Kia Syros, is something which is eating into its sales. However, being the direct sibling of the segment-leader Hyundai Creta, the Kia Seltos is a capable offering, if not better.
Kia has recently launched the new-gen Kia Seltos.

- Seating Capacity: 5
- Body Type: Mid-size SUV
Kia Carens
Selling 3,681 units in December 2025, Kia Carens saw a 40 percent growth in its year-on-year sales. As a premium 6- or 7-seater MUV, the Kia Carens has proven itself to be a capable and affordable alternative to the Toyota Innova. Moreover, with the space and comfort it offers, the Carens is one of the best seven-seater cars in India. At the same time, adding greatly to the sales of the Carens is the success of the recently launched Kia Carens Clavis, which is a more premium version of the Kia Carens. The Korean carmaker has also launched the electric version of the Carens Clavis, Kia Carens Clavis EV. Meanwhile, Kia has discontinued most variants of the Kia Carens, leaving only the Premium (O) seven-seater variant.
Kia Carens Specifications
- Engine: 1.5 litre petrol engine | 1.5 litre turbo petrol engine (Clavis) | 1.4-litre turbo petrol engine | 1.5-litre turbo diesel engine

- Airbags: 6 airbags as standard

Kia Syros
The Kia Syros sold 1,116 units in December 2025. Syros’s sales have seen a steep decline in the past few months, even though it is a great value-for-money offering. Slotted between the Kia Sonet and the Kia Seltos, the Kia Syros is more modern than both, and in typical Kia fashion, it packs a lot of technological perks. Meanwhile, the Syros has scored a 5-star rating in the Bharat NCAP safety test and is one of the safest cars in India.

Kia Carnival
The Kia Carnival premium MUV sold 75 units in December 2025. These are impressive sales figures for a car priced at Rs 59.42 lakh (ex-showroom), even though they were 27 percent less than the sales it did in the same month last year. The Carnival offers high-end comfort in its lounge-like cabin, which features seven seats: two captain seats in the middle row and a bench seat in the last row.
