Three-Way Specification Comparison
Kia Sonet in short
The Kia Sonet is one of the most feature-loaded sub-4-metre SUVs on sale, and its 2024 facelift sharpened the styling while making six airbags standard across the range. It remains the only car in its class to offer a diesel-automatic combination, giving it a unique selling point against the Tata Nexon, Maruti Brezza, Hyundai Venue and Mahindra XUV 3XO. The wide engine-gearbox matrix and segment-first features like ventilated seats and a 360-degree camera keep it a strong all-rounder.
