Citroen AircrossX in short

The AircrossX is the October 2025 refresh of the C3 Aircross, and at ₹8.89 lakh it is India's cheapest 7-seat SUV. It offers 5- and 7-seat layouts, 200 mm of ground clearance, a 444-litre boot in 5-seat form and the same 82 PS NA / 110 PS turbo 1.2 petrol pair as the BasaltX with 6-speed manual or torque-converter automatic. A 5-star Bharat NCAP adult-occupant rating and six standard airbags give it a safety edge over the Maruti Ertiga and Renault Triber it undercuts on the 7-seat count.

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.
