Hyundai i20 vs Mahindra Thar OG Comparison 2026: Price, Mileage, Features

Comparison overview: The Hyundai i20 starts at ₹6.00 L and the Mahindra Thar OG at ₹10.32 L, a difference of ₹4.32 L ex-showroom. On-road in New Delhi that gap becomes roughly ₹4.80 L. Here is what the extra money actually buys.

Engine and performance: The Hyundai i20 uses a 1,197cc Petrol making 87bhp@6000rpm and listed torque with Automatic/Manual. The Mahindra Thar OG uses a 1,497cc Diesel/Petrol making 116.93 - 159.58 bhp and listed torque with Automatic/Manual.

Mileage and running cost: These two figures are not like for like. The Hyundai i20 number is for the Petrol Automatic/Manual and the Mahindra Thar OG number is for the Diesel/Petrol Automatic/Manual, so compare the variants you are actually shortlisting.

What one gives that the other does not: The Hyundai i20 adds Anti-lock Braking System (ABS), Central Locking, Anti-Theft Alarm, No. of Airbags and Driver Airbag. The rest of both spec sheets is shared.

Which one should you buy?

Buy the Hyundai i20 if you drive mostly in the city, you want the lower running cost, and you would rather keep the ₹4.32 L for your down payment than spend it on features.

Buy the Mahindra Thar OG if you do regular highway runs, you carry luggage or a pram often, and you want useful comfort features without waiting for the next facelift.

The one thing that settles it: Hyundai i20 offers Anti-lock Braking System (ABS).

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.
