Available Engine Options in the 2026 Kia Sonet
The SUV continues to be offered with three engine choices, ensuring flexibility for different driving needs. These powertrains cater to buyers who prioritise efficiency, performance, or affordability.
Engine Specifications Overview

The naturally aspirated petrol engine is aimed at buyers seeking a simple and cost-effective option, while the turbo petrol variant delivers stronger performance. The diesel engine, known for its higher torque output, is suitable for those who require better pulling power and highway efficiency.
Impact on the Compact SUV Segment
With the addition of new automatic trims, the Sonet diesel automatic variants are now positioned to compete more aggressively in the compact SUV market. The availability of lower-priced automatic options could make the model more appealing to first-time SUV buyers as well as customers upgrading from manual transmission vehicles.
Providing multiple transmission options also enhances the Sonet’s overall versatility. Buyers can now find combinations that match their driving habits, whether focused on city traffic comfort or long-distance travel convenience.
Conclusion: What the Sonet Update Means for Buyers
The expansion of the 2026 Kia Sonet lineup with new diesel and petrol automatic variants represents an important update for the compact SUV segment. By making the diesel automatic configuration more affordable and widely available, Kia has increased accessibility for a larger group of customers.
This development matters because it reflects rising demand for automatic vehicles in India’s urban markets. Buyers should understand that the updated Sonet now offers greater flexibility in terms of pricing, engine choices, and transmission options.
Going forward, the introduction of new variants and styling updates such as the Magma Red colour is likely to strengthen the Sonet’s competitiveness.
