Tata Nexon vs Mahindra Thar OG Comparison 2026: Price, Mileage, Features

Comparison overview: The Tata Nexon starts at ₹7.40 L and the Mahindra Thar OG at ₹10.32 L, a difference of ₹2.92 L ex-showroom. On-road in New Delhi that gap becomes roughly ₹3.24 L. Here is what the extra money actually buys.

Engine and performance: The Tata Nexon uses a 1,497cc Diesel/Petrol/CNG making Diesel - 113.31bhp@3750rpm,Petrol - 118.27bhp@5500rpm,CNG - 99bhp@5000rpm 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 Tata Nexon number is for the Diesel/Petrol/CNG Automatic/Manual and the Mahindra Thar OG number is for the Diesel/Petrol Automatic/Manual, so compare the variants you are actually shortlisting.

Only the Tata Nexon comes with a factory CNG option at Diesel - 24.08 kmpl,Petrol - 17.44 kmpl, which is the cheapest way to run either car in the city.

What one gives that the other does not: The Tata Nexon adds Anti-lock Braking System (ABS), Central Locking, Child Safety Locks, Anti-Theft Alarm and No. of Airbags. The rest of both spec sheets is shared.

Which one should you buy?

Buy the Tata Nexon if you drive mostly in the city, you want the lower running cost, and you would rather keep the ₹2.92 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: Tata Nexon 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.
