Kia India has taken the wrap off the new generation iteration of Kia Seltos. The second generation iteration of the popular SUV is expected to boost the appeal of this model further. With the new Seltos unveiled and booking commenced at a token amount of ₹25,000, Kia will announce its pricing on January 2, 2026. With a significant amount of changes at exterior and inside the cabin, the 2026 Kia Seltos aims to strengthen its position further in the highly competitive Indian SUV segment, where it will compete with already established models, as well as a newcomer - Tata Sierra.

The Tata Sierra has already grabbed a lot of eyeballs, after making its debut, as one of the key launches in the country in 2025. With this, Tata Motors brought back one of the most hyped nomenclatures in the Indian passenger vehicle market. The new generation Tata Sierra comes as a modernised and advanced tech-enabled iteration of the original model that was in business in India during the last decade of last century.

If you are planning to buy a SUV soon, and exploring these two models, here is a quick comparison of the dimension and powertrain specifications of the new generation 2026 Kia Seltos and Tata Sierra.
