Mahindra Thar ROXX vs Kia Carens Comparison 2026: Price, Mileage, Features

Comparison overview: The Mahindra Thar ROXX starts at ₹12.39 L and the Kia Carens at ₹11.02 L, a difference of ₹1.37 L ex-showroom. On-road in New Delhi that gap becomes roughly ₹1.52 L. Here is what the extra money actually buys.

Engine and performance: The Mahindra Thar ROXX uses a 1,997cc Diesel/Petrol making 172bhp@3500rpm,160bhp@5000rpm and listed torque with Automatic/Manual. The Kia Carens uses a 1,493cc Diesel/Petrol/CNG making 113.42 - 114.41 bhp and listed torque with Manual.

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

Only the Kia Carens comes with a factory CNG option at 12.6 kmpl, which is the cheapest way to run either car in the city.

What one gives that the other does not: The Mahindra Thar ROXX adds Traction Control, Anti-Pinch Power Windows, Blind Spot Camera, 360 View Camera and Bharat NCAP Safety Rating. The Kia Carens adds Anti-Theft Alarm, Door Ajar Warning, Global NCAP Safety Rating, Global NCAP Child Safety Rating and Adjustable Headlamps. The rest of both spec sheets is shared.

Which one should you buy?

Buy the Kia Carens if you drive mostly in the city, you want the lower running cost, and you would rather keep the ₹1.37 L for your down payment than spend it on features.

Buy the Mahindra Thar ROXX if you do regular highway runs, you carry luggage or a pram often, and you want Anti-lock Braking System (ABS) without waiting for the next facelift.

The one thing that settles it: Mahindra Thar ROXX offers Traction Control.

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.
