Mahindra XUV 3XO vs Kia Sonet Comparison 2026: Price, Mileage, Features

Comparison overview: The Mahindra XUV 3XO starts at ₹7.79 L and the Kia Sonet at ₹7.41 L, a difference of ₹38.10 K ex-showroom. On-road in New Delhi that gap becomes roughly ₹42.29 K. Here is what the extra money actually buys.

Engine and performance: The Mahindra XUV 3XO uses a 1,197cc Diesel/Petrol/CNG making 109.96 - 128.73 bhp and listed torque with Automatic/Manual. The Kia Sonet uses a 1,493cc Diesel/Petrol making 114bhp@4000rpm,118bhp@6000rpm and listed torque with Automatic/Manual.

Mileage and running cost: These two figures are not like for like. The Mahindra XUV 3XO number is for the Diesel/Petrol/CNG Automatic/Manual and the Kia Sonet number is for the Diesel/Petrol Automatic/Manual, so compare the variants you are actually shortlisting.

Only the Mahindra XUV 3XO comes with a factory CNG option at 17.96 kmpl - 24.7 km/kg, which is the cheapest way to run either car in the city.

Space and practicality: The Kia Sonet takes 385 litres against 364, about 21 litres more. That is roughly one extra cabin-size bag of extra room.

What one gives that the other does not: The Mahindra XUV 3XO adds Petrol Mileage ARAI, Petrol Fuel Tank Capacity, Turning Radius, Height Adjustable Front Seat Belts and Glove Box light. The Kia Sonet adds Curtain Airbag, Seat Belt Warning, Door Ajar Warning, Anti-Theft Device and Anti-Pinch Power Windows. The rest of both spec sheets is shared.

Which one should you buy?

Buy the Kia Sonet if you drive mostly in the city, you want the lower running cost, and you would rather keep the ₹38.10 K for your down payment than spend it on features.

Buy the Mahindra XUV 3XO if you do regular highway runs, you carry luggage or a pram often, and you want Engine Type without waiting for the next facelift.

The one thing that settles it: Mahindra XUV 3XO offers Petrol Mileage ARAI.

Before you sign anything:

Ex-showroom price is not what you pay. Add registration, road tax, insurance and handling, and expect the final figure to land ten to twelve percent higher. Road tax changes state to state, so a car that costs the same in two cities does not cost the same to own.

Ask the dealer four things before you book. What is the current waiting period for the variant you want. What is the on-road figure.

Then drive both cars back to back on the same day, on a road you actually use. Take your family. Put your usual luggage in the boot. Most people decide in the first ten minutes, and it is rarely for the reason they expected.
